  • Northwind now available on SQL Azure

    - by jamiet
    Two weeks ago I made available a copy of [AdventureWorks2012] on SQL Azure and published credentials so that anyone from the SQL community could connect up and experience SQL Azure, probably for the first time. One of the (somewhat) popular requests thereafter was to make the venerable Northwind database available too so I am pleased to say that as of right now, Northwind is up there too. You will notice immediately that all of the Northwind tables (and the stored procedures and views too) have been moved into a schema called [Northwind] – this was so that they could be easily differentiated from the existing [AdventureWorks2012] objects. I used an SQL Server Data Tools (SSDT) project to publish the schema and data up to this SQL Azure database; if you are at all interested in poking around that SSDT project then I have made it available on Codeplex for your convenience under the MS-PL license – go and get it from https://northwindssdt.codeplex.com/. Using SSDT proved particularly useful as it alerted me to some aspects of Northwind that were not compatible with SQL Azure, namely that five of the tables did not have clustered indexes: The beauty of using SSDT is that I am alerted to these issues before I even attempt a connection to SQL Azure. Pretty cool, no? Fixing this situation was of course very easy, I simply changed the following primary keys from being nonclustered to clustered: [PK_Region] [PK_CustomerDemographics] [PK_EmployeeTerritories] [PK_Territories] [PK_CustomerCustomerDemo]   If you want to connect up then here are the credentials that you will need: Server mhknbn2kdz.database.windows.net Database AdventureWorks2012 User sqlfamily Password sqlf@m1ly You will need SQL Server Management Studio (SSMS) 2008R2 installed in order to connect or alternatively simply use this handy website: https://mhknbn2kdz.database.windows.net which provides a web interface to a SQL Azure server. Do remember that hosting this database is not free so if you find that you are making use of it please help to keep it available by visiting Paypal and donating any amount at all to [email protected]. To make this easy you can simply hit this link and the details will be completed for you – all you have to do is login and hit the “Send” button. If you are already a PayPal member then it should take you all of about 20 seconds! I hope this is useful to some of you folks out there. Don’t forget that we also have more data up there than in the conventional [AdventureWorks2012], read more at Big AdventureWorks2012. @Jamiet  AdventureWorks on Azure - Provided by the SQL Server community, for the SQL Server community!

  • How migrate my keyring (containing ssh passprases, nautilus remote filesystem, pgp passwords) and network manager connections?

    - by con-f-use
    I changed the disk on my laptop and installed Ubuntu on the new disk. Old disk had 12.04 upgraded to 12.10 on it. Now I want to copy my old keyring with WiFi passwords, ftp passwords for nautilus and ssh key passphrases. I have the whole data from the old disk available (is now a USB disk and I did not delete the old data yet or do anything with it - I could still put it in the laptop and boot from it like nothing happened). On the new disc that is now in my laptop, I have installed 12.10 with the same password, user-id and username as on the old disk. Then I copied a few important config files from the old disk (e.g. ~/.firefox/, ~/.mozilla, ~/.skype and so on, which all worked fine... except for the key ring: The old methods of just copying ~/.gconf/... and ~/.gnome2/keyrings won't work. Did I miss something? 1. Edit: I figure one needs to copy files not located in the users home directory as well. I copied the whole old /home/confus (which is my home directory) to the fresh install to no effect. That whole copy is now reverted to the fresh install's home directory, so my /home/confus is as it was the after fresh install. 2. Edit: The folder /etc/NetworkManager/system-connections seems to be the place for WiFi passwords. Could be that /usr/share/keyrings is important as well for ssh keys - that's the only sensible thing that a search came up with: find /usr/ -name "*keyring* 3. Edit: Still no ssh and ftp passwords from the keyring. What I did: Convert old hard drive to usb drive Put new drive in the laptop and installed fresh version of 12.10 there (same uid, username and passwort) Booted from old hdd via USB and copied its /etc/NetwrokManager/system-connections, ~/.gconf/ and ~/.gnome2/keyrings, ~/.ssh over to the new disk. Confirmed that all keys on the old install work Booted from new disk Result: No passphrase for ssh keys, no ftp passwords in keyring. At least the WiFi passwords are migrated. 4. Edit: Boutny! Ending soon... 5. Edit: Keyring's now in ./local/share/keyrings/. Also interesting .gnupg

  • General Policies and Procedures for Maintaining the Value of Data Assets

    Here is a general list for policies and procedures regarding maintaining the value of data assets. Data Backup Policies and Procedures Backups are very important when dealing with data because there is always the chance of losing data due to faulty hardware or a user activity. So the need for a strategic backup system should be mandatory for all companies. This being said, in the real world some companies that I have worked for do not really have a good data backup plan. Typically when companies tend to take this kind of approach in data backups usually the data is not really recoverable.  Unfortunately when companies do not regularly test their backup plans they get a false sense of security because they think that they are covered. However, I can tell you from personal and professional experience that a backup plan/system is never fully implemented until it is regularly tested prior to the time when it actually needs to be used. Disaster Recovery Plan Expanding on Backup Policies and Procedures, a company needs to also have a disaster recovery plan in order to protect its data in case of a catastrophic disaster.  Disaster recovery plans typically encompass how to restore all of a company’s data and infrastructure back to a restored operational status.  Most Disaster recovery plans also include time estimates on how long each step of the disaster recovery plan should take to be executed.  It is important to note that disaster recovery plans are never fully implemented until they have been tested just like backup plans. Disaster recovery plans should be tested regularly so that the business can be confident in not losing any or minimal data due to a catastrophic disaster. Firewall Policies and Content Filters One way companies can protect their data is by using a firewall to separate their internal network from the outside. Firewalls allow for enabling or disabling network access as data passes through it by applying various defined restrictions. Furthermore firewalls can also be used to prevent access from the internal network to the outside by these same factors. Common Firewall Restrictions Destination/Sender IP Address Destination/Sender Host Names Domain Names Network Ports Companies can also desire to restrict what their network user’s view on the internet through things like content filters. Content filters allow a company to track what webpages a person has accessed and can also restrict user’s access based on established rules set up in the content filter. This device and/or software can block access to domains or specific URLs based on a few factors. Common Content Filter Criteria Known malicious sites Specific Page Content Page Content Theme  Anti-Virus/Mal-ware Polices Fortunately, most companies utilize antivirus programs on all computers and servers for good reason, virus have been known to do the following: Corrupt/Invalidate Data, Destroy Data, and Steal Data. Anti-Virus applications are a great way to prevent any malicious application from being able to gain access to a company’s data.  However, anti-virus programs must be constantly updated because new viruses are always being created, and the anti-virus vendors need to distribute updates to their applications so that they can catch and remove them. Data Validation Policies and Procedures Data validation is very important to ensure that only accurate information is stored. The existence of invalid data can cause major problems when businesses attempt to use data for knowledge based decisions and for performance reporting. Data Scrubbing Policies and Procedures Data scrubbing is valuable to companies in one of two ways. The first can be used to clean data prior to being analyzed for report generation. The second is that it allows companies to remove things like personally Identifiable information from its data prior to transmit it between multiple environments or if the information is sent to an external location. An example of this can be seen with medical records in regards to HIPPA laws that prohibit the storage of specific personal and medical information. Additionally, I have professionally run in to a scenario where the Canadian government does not allow any Canadian’s personal information to be stored on a server not located in Canada. Encryption Practices The use of encryption is very valuable when a company needs to any personal information. This allows users with the appropriated access levels to view or confirm the existence or accuracy of data within a system by either decrypting the information or encrypting a piece of data and comparing it to the stored version.  Additionally, if for some unforeseen reason the data got in to the wrong hands then they would have to first decrypt the data before they could even be able to read it. Encryption just adds and additional layer of protection around data itself. Standard Normalization Practices The use of standard data normalization practices is very important when dealing with data because it can prevent allot of potential issues by eliminating the potential for unnecessary data duplication. Issues caused by data duplication include excess use of data storage, increased chance for invalidated data, and over use of data processing. Network and Database Security/Access Policies Every company has some form of network/data access policy even if they have none. These policies help secure data from being seen by inappropriate users along with preventing the data from being updated or deleted by users. In addition, without a good security policy there is a large potential for data to be corrupted by unassuming users or even stolen. Data Storage Policies Data storage polices are very important depending on how they are implemented especially when a company is trying to utilize them in conjunction with other policies like Data Backups. I have worked at companies where all network user folders are constantly backed up, and if a user wanted to ensure the existence of a piece of data in the form of a file then they had to store that file in their network folder. Conversely, I have also worked in places where when a user logs on or off of the network there entire user profile is backed up. Training Policies One of the biggest ways to prevent data loss and ensure that data will remain a company asset is through training. The practice of properly train employees on how to work with in systems that access data is crucial when trying to ensure a company’s data will remain an asset. Users need to be trained on how to manipulate a company’s data in order to perform their tasks to reduce the chances of invalidating data.

  • Five Fake Sounds Engineered to Make Your Feel Better [Science]

    - by Jason Fitzpatrick
    As objects in our environment (like cars, ATMs, and phones) have grown lighter and quieter scientists have been carefully engineering their sounds so that they continue to sound like we expect them to. Read on to see how. At the design blog Humans Invent they share five interesting ways that the world around us is being engineered so it sounds the way we expect it to. They start with the example of the car door. Years ago cars were almost entirely steel, the doors were weighty, and when you slammed them it sounded like one big hunk of steel locking into another big hunk of steel (which, in fact, it was). Newer cars are lighter but people still crave that substantial clunk. Humans Invent highlights the effect of consumer desire: A car door is essentially a hollow shell with parts placed inside it. Without careful design the door frame amplifies the rattling of mechanisms inside. Car companies know that if buyers don’t get a satisfying thud when they close the door, it dents their confidence in the entire vehicle. To produce the ideal clunk, car doors are designed to minimise the amount of high frequencies produced (we associate them with fragility and weakness) and emphasise low, bass-heavy frequencies that suggest solidity. The effect is achieved in a range of different ways – car companies have piled up hundreds of patents on the subject – but usually involves some form of dampener fitted in the door cavity. Locking mechanisms are also tailored to produce the right sort of click and the way seals make contact is precisely controlled. On average it takes 1.8 seconds to close a car door but in that time you’re witnessing a strange kind of symphony composed by engineers and designers whose goal is to reassure you that its rock solid. They mention lock mechanisms, something you may never have thought about. A friend of mine had a Ford Focus some years ago and that particular model had electric locks that, instead of giving a satisfying thunk or solid click, made this horrible gates-of-the-prison-buzzing sound that was completely unnerving. Hit up the link below to see how sounds are engineered for car doors, electric motors, ATM machines, and more. 5 Fake Sounds Designed to Help Humans [Humans Invent via Boing Boing] How To Easily Access Your Home Network From Anywhere With DDNSHow To Recover After Your Email Password Is CompromisedHow to Clean Your Filthy Keyboard in the Dishwasher (Without Ruining it)

  • A Bite With No Teeth&ndash;Demystifying Non-Compete Clauses

    - by D'Arcy Lussier
    *DISCLAIMER: I am not a lawyer and this post in no way should be considered legal advice. I’m also in Canada, so references made are to Canadian court cases. I received a signed letter the other day, a reminder from my previous employer about some clauses associated with my employment and entry into an employee stock purchase program. So since this is in effect for the next 12 months, I guess I’m not starting that new job tomorrow. I’m kidding of course. How outrageous, how presumptuous, pompous, and arrogant that a company – any company – would actually place these conditions upon an employee. And yet, this is not uncommon. Especially in the IT industry, we see time and again similar wording in our employment agreements. But…are these legal? Is there any teeth behind the threat of the bite? Luckily, the answer seems to be ‘No’. I want to highlight two cases that support this. The first is Lyons v. Multari. In a nutshell, Dentist hires younger Dentist to be an associate. In their short, handwritten agreement, a non-compete clause was written stating “Protective Covenant. 3 yrs. – 5mi” (meaning you can’t set up shop within 5 miles for 3 years). Well, the young dentist left and did start an oral surgery office within 5 miles and within 3 years. Off to court they go! The initial judge sided with the older dentist, but on appeal it was overturned. Feel free to read the transcript of the decision here, but let me highlight one portion from section [19]: The general rule in most common law jurisdictions is that non-competition clauses in employment contracts are void. The sections following [19] explain further, and discuss Elsley v. J.G. Collins Insurance Agency Ltd. and its impact on Canadian law in this regard. The second case is Winnipeg Livestock Sales Ltd. v. Plewman. Desmond Plewman is an auctioneer, and worked at Winnipeg Livestock Sales. Part of his employment agreement was that he could not work for a competitor for 18 months if he left the company. Well, he left, and took up an important role in a competing company. The case went to court and as with Lyons v. Multari, the initial judge found in favour of the plaintiffs. Also as in the first case, that was overturned on appeal. Again, read through the transcript of the decision, but consider section [28]: In other words, even though Plewman has a great deal of skill as an auctioneer, Winnipeg Livestock has no proprietary interest in his professional skill and experience, even if they were acquired during his time working for Winnipeg Livestock.  Thus, Winnipeg Livestock has the burden of establishing that it has a legitimate proprietary interest requiring protection.  On this key question there is little evidence before the Court.  The record discloses that part of Plewman’s job was to “mingle with the … crowd” and to telephone customers and prospective customers about future prospects for the sale of livestock.  It may seem reasonable to assume that Winnipeg Livestock has a legitimate proprietary interest in its customer connections; but there is no evidence to indicate that there is any significant degree of “customer loyalty” in the business, as opposed to customers making choices based on other considerations such as cost, availability and the like. So are there any incidents where a non-compete can actually be valid? Yes, and these are considered “exceptional” cases, meaning that the situation meets certain circumstances. Michael Carabash has a great blog series discussing the above mentioned cases as well as the difference between a non-compete and non-solicit agreement. He talks about the exceptional criteria: In summary, the authorities reveal that the following circumstances will generally be relevant in determining whether a case is an “exceptional” one so that a general non-competition clause will be found to be reasonable: - The length of service with the employer. - The amount of personal service to clients. - Whether the employee dealt with clients exclusively, or on a sustained or     recurring basis. - Whether the knowledge about the client which the employee gained was of a   confidential nature, or involved an intimate knowledge of the client’s   particular needs, preferences or idiosyncrasies. - Whether the nature of the employee’s work meant that the employee had   influence over clients in the sense that the clients relied upon the employee’s   advice, or trusted the employee. - If competition by the employee has already occurred, whether there is   evidence that clients have switched their custom to him, especially without   direct solicitation. - The nature of the business with respect to whether personal knowledge of   the clients’ confidential matters is required. - The nature of the business with respect to the strength of customer loyalty,   how clients are “won” and kept, and whether the clientele is a recurring one. - The community involved and whether there were clientele yet to be exploited   by anyone. I close this blog post with a final quote, one from Zvulony & Co’s blog post on this subject. Again, all of this is not official legal advice, but I think we can see what all these sources are pointing towards. To answer my earlier question, there’s no teeth behind the threat of the bite. In light of this list, and the decisions in Lyons and Orlan, it is reasonably certain that in most employment situations a non-competition clause will be ineffective in protecting an employer from a departing employee who wishes to compete in the same business. The Courts have been relatively consistent in their position that if a non-solicitation clause can protect an employer’s interests, then a non-competition clause is probably unreasonable. Employers (or their solicitors) should avoid the inclination to draft restrictive covenants in broad, catch-all language. Or in other words, when drafting a restrictive covenant – take only what you need! D

  • Setting up port forwarding for 7000 appliance VM in VirtualBox

    - by uejio
    I've been using the 7000 appliance VM for a lot of testing lately and relied on others to set up the networking for the VM for me, but finally, I decided to take the dive and do it myself.  After some experimenting, I came up with a very brief number of steps to do this all using the VirtualBox CLI instead of the GUI. First download the VM image and unpack it somewhere.  I put it in /var/tmp. Then, set your VBOX_USER_HOME to some place with lots of disk space and import the VM: export VBOX_USER_HOME=/var/tmp/MyVirtualBoxVBoxManage import /var/tmp/simulator/vbox-2011.1.0.0.1.1.8/Sun\ ZFS\ Storage\ 7000.ovf (go get a cup of tea...) Then, set up port forwarding of the VM appliance BUI and shell:First set up port as NAT:VBoxManage modifyvm Sun_ZFS_Storage_7000 --nic1 nat Then set up rules for port forwarding (pick some unused port numbers):VBoxManage modifyvm Sun_ZFS_Storage_7000 --natpf1 "guestssh,tcp,,4622,,22"VBoxManage modifyvm Sun_ZFS_Storage_7000 --natpf1 "guestbui,tcp,,46215,,215" Verify the settings using:VBoxManage showvminfo Sun_ZFS_Storage_7000 | grep -i nic Start the appliance:$ VBoxHeadless --startvm Sun_ZFS_Storage_7000 & Connect to it using your favorite RDP client.  I use a Sun Ray, so I use the Sun Ray Windows Connector client: $ /opt/SUNWuttsc/bin/uttsc -g 800x600 -P <portnumber> <your-hostname> & The portnumber is displayed in the output of the --startvm command.(This did not work after I updated to VirtualBox 4.1.12, so maybe at this point, you need to use the VirtualBox GUI.) It takes a while to first bring up the VM, so please be patient. The longest time is in loading the smf service descriptions, but fortunately, that only needs to be done the first time the VM boots.  There is also a delay in just booting the appliance, so give it some time. Be sure to set the NIC rule on only one port and not all ports otherwise there will be a conflict in ports and it won't work. After going through the initial configuration screen, you can connect to it using ssh or your browser: ssh -p 45022 root@<your-host-name> https://<your-host-name>:45215 BTW, for the initial configuration, I only had to set the hostname and password.  The rest of the defaults were set by VirtualBox and seemed to work fine.

  • Questions about identifying the components in MVC

    - by luiscubal
    I'm currently developing an client-server application in node.js, Express, mustache and MySQL. However, I believe this question should be mostly language and framework agnostic. This is the first time I'm doing a real MVC application and I'm having trouble deciding exactly what means each component. (I've done web applications that could perhaps be called MVC before, but I wouldn't confidently refer to them as such) I have a server.js that ties the whole application together. It does initialization of all other components (including the database connection, and what I think are the "models" and the "views"), receiving HTTP requests and deciding which "views" to use. Does this mean that my server.js file is the controller? Or am I mixing code that doesn't belong there? What components should I break the server.js file into? Some examples of code that's in the server.js file: var connection = mysql.createConnection({ host : 'localhost', user : 'root', password : 'sqlrevenge', database : 'blog' }); //... app.get("/login", function (req, res) { //Function handles a GET request for login forms if (process.env.NODE_ENV == 'DEVELOPMENT') { mu.clearCache(); } session.session_from_request(connection, req, function (err, session) { if (err) { console.log('index.js session error', err); session = null; } login_view.html(res, user_model, post_model, session, mu); //I named my view functions "html" for the case I might want to add other output types (such as a JSON API), or should I opt for completely separate views then? }); }); I have another file that belongs named session.js. It receives a cookies object, reads the stored data to decide if it's a valid user session or not. It also includes a function named login that does change the value of cookies. First, I thought it would be part of the controller, since it kind of dealt with user input and supplied data to the models. Then, I thought that maybe it was a model since it dealt with the application data/database and the data it supplies is used by views. Now, I'm even wondering if it could be considered a View, since it outputs data (cookies are part of HTTP headers, which are output)

  • Publishing an Excel spreadsheet using Microsoft SBS 2008 to a web page that is viewable by mobile ph

    - by Dave Heath
    I am getting well out of my “superuser” depth here and would love some support. At work we have an Excel workbook (*.xls format circa Office 2003) which maintains our “engineers” timesheet. This handles what events we are doing across the year and how many “work units” it is. As far as a workbook goes, it is fairly simple with just a few =SUM(range) cells and some linked across sheets (12 sheets, one for each month) It is stored on a server, in a folder that provides “management” with full access and “engineers” with read-only access. The workbook itself is read-only for “engineers” and full access for “management”. I think these permissions are controlled through Active Directory. The workbook is protected with a password, assumingly to allow “management” to edit it even if they are working at a terminal logged in as an “engineer”. This protection prevents “engineers” from going to certain cells to see formulae and therefore editing them. The workbook has a macro which saves and closes it ten minutes after opening. This is to stop other “management” from being locked out by any one person who has logged in with editing privileges. I hope this is making sense to someone... :S Now then, we have Microsoft Small Business Server 2008. We have a shiny new web-based login for when we are offsite so we can get to Exchange webmail and our internal site (which uses Sharepoint 3.0). “Management” would like to be able to publish this timesheet automatically after changes (they don’t want to have to do anything different to what they are currently doing) so that using an iPhone “engineers” can check on it while out of the office. I am currently having a look at “Excel Services” for Office 2007 on TechNet but I am not sure if I am running down the right garden path at the moment. < EDIT This seems to suggest that I have to have Sharepoint Server 2007, with no mention of Sharepoint 3.0... ... "MOSS builds on WSS by adding both core features as well as end user web parts" - Wikipedia entry for Microsoft Office SharePoint Server (MOSS) this is not good news... "...and using the ASP.NET APIs, web parts can be written to extend the functionality of WSS." Wikipedia entry for Windows Sharepoint Services. Could this bring back what I need? Is this good news? Do I need to start learning ASP.NET? This link here implies that we need MOSS to do what I want and the bosses say we aint' getting it. http://serverfault.com/questions/20198/what-is-some-cool-things-you-can-do-with-sharepoint-2007/22128#22128 Back to the drawing board. < /EDIT Please could someone suggest some “further reading” for me to help point me in the right direction or to put me back on the right track. Many thanks. I will try to keep this up to date with how I get on.

  • Super constructor must be a first statement in Java constructor [closed]

    - by Val
    I know the answer: "we need rules to prevent shooting into your own foot". Ok, I make millions of programming mistakes every day. To be prevented, we need one simple rule: prohibit all JLS and do not use Java. If we explain everything by "not shooting your foot", this is reasonable. But there is not much reason is such reason. When I programmed in Delphy, I always wanted the compiler to check me if I read uninitializable. I have discovered myself that is is stupid to read uncertain variable because it leads unpredictable result and is errorenous obviously. By just looking at the code I could see if there is an error. I wished if compiler could do this job. It is also a reliable signal of programming error if function does not return any value. But I never wanted it do enforce me the super constructor first. Why? You say that constructors just initialize fields. Super fields are derived; extra fields are introduced. From the goal point of view, it does not matter in which order you initialize the variables. I have studied parallel architectures and can say that all the fields can even be assigned in parallel... What? Do you want to use the unitialized fields? Stupid people always want to take away our freedoms and break the JLS rules the God gives to us! Please, policeman, take away that person! Where do I say so? I'm just saying only about initializing/assigning, not using the fields. Java compiler already defends me from the mistake of accessing notinitialized. Some cases sneak but this example shows how this stupid rule does not save us from the read-accessing incompletely initialized in construction: public class BadSuper { String field; public String toString() { return "field = " + field; } public BadSuper(String val) { field = val; // yea, superfirst does not protect from accessing // inconstructed subclass fields. Subclass constr // must be called before super()! System.err.println(this); } } public class BadPost extends BadSuper { Object o; public BadPost(Object o) { super("str"); this. o = o; } public String toString() { // superconstructor will boom here, because o is not initialized! return super.toString() + ", obj = " + o.toString(); } public static void main(String[] args) { new BadSuper("test 1"); new BadPost(new Object()); } } It shows that actually, subfields have to be inilialized before the supreclass! Meantime, java requirement "saves" us from writing specializing the class by specializing what the super constructor argument is, public class MyKryo extends Kryo { class MyClassResolver extends DefaultClassResolver { public Registration register(Registration registration) { System.out.println(MyKryo.this.getDepth()); return super.register(registration); } } MyKryo() { // cannot instantiate MyClassResolver in super super(new MyClassResolver(), new MapReferenceResolver()); } } Try to make it compilable. It is always pain. Especially, when you cannot assign the argument later. Initialization order is not important for initialization in general. I could understand that you should not use super methods before initializing super. But, the requirement for super to be the first statement is different. It only saves you from the code that does useful things simply. I do not see how this adds safety. Actually, safety is degraded because we need to use ugly workarounds. Doing post-initialization, outside the constructors also degrades safety (otherwise, why do we need constructors?) and defeats the java final safety reenforcer. To conclude Reading not initialized is a bug. Initialization order is not important from the computer science point of view. Doing initalization or computations in different order is not a bug. Reenforcing read-access to not initialized is good but compilers fail to detect all such bugs Making super the first does not solve the problem as it "Prevents" shooting into right things but not into the foot It requires to invent workarounds, where, because of complexity of analysis, it is easier to shoot into the foot doing post-initialization outside the constructors degrades safety (otherwise, why do we need constructors?) and that degrade safety by defeating final access modifier When there was java forum alive, java bigots attecked me for these thoughts. Particularly, they dislaked that fields can be initialized in parallel, saying that natural development ensures correctness. When I replied that you could use an advanced engineering to create a human right away, without "developing" any ape first, and it still be an ape, they stopped to listen me. Cos modern technology cannot afford it. Ok, Take something simpler. How do you produce a Renault? Should you construct an Automobile first? No, you start by producing a Renault and, once completed, you'll see that this is an automobile. So, the requirement to produce fields in "natural order" is unnatural. In case of alarmclock or armchair, which are still chair and clock, you may need first develop the base (clock and chair) and then add extra. So, I can have examples where superfields must be initialized first and, oppositely, when they need to be initialized later. The order does not exist in advance. So, the compiler cannot be aware of the proper order. Only programmer/constructor knows is. Compiler should not take more responsibility and enforce the wrong order onto programmer. Saying that I cannot initialize some fields because I did not ininialized the others is like "you cannot initialize the thing because it is not initialized". This is a kind of argument we have. So, to conclude once more, the feature that "protects" me from doing things in simple and right way in order to enforce something that does not add noticeably to the bug elimination at that is a strongly negative thing and it pisses me off, altogether with the all the arguments to support it I've seen so far. It is "a conceptual question about software development" Should there be the requirement to call super() first or not. I do not know. If you do or have an idea, you have place to answer. I think that I have provided enough arguments against this feature. Lets appreciate the ones who benefit form it. Let it just be something more than simple abstract and stupid "write your own language" or "protection" kind of argument. Why do we need it in the language that I am going to develop?

  • Black screen on latest Nvidia Cards when starting LightDM/Ubuntu

    - by Luis Alvarado
    Today I installed an Nvidia GT440 on my computer, changing the one that existed there, an Nvidia 9500GT. After changing it I started getting a problem where the screen just went black when loading the lightdm login screen (Where I punt my user and password). The thing is, if I disconnect the VGA cable and connect it again I get to see the lightdm greeter and everything works perfect. The problem is that I have to connect/disconnect every time I reboot the PC. I tried installing the 285.xx drivers. Same problem. I removed the Nvidia drivers installed with Jockey, rebooted, same problem. I install the current 280.xx again, same problem. After all that I installed a fresh install of Ubuntu, selected to install the Nvidia drivers while installing it from the livecd. After booting the same problem appeared. Dmesg does not say anything wrong about it. Same goes for the log from Jockey. What else should I check or what to do to solve it. Just to clarify, this does not happen BEFORE the lightdm greeter appears. Am guessing before the actual use of the video card with X starts with all the 2D/3D stuff that is used in ligthdm and unity. I can use any tty and even see the Ubuntu logo when starting. UPDATE: When I open a game in fullscreen the problem appears again. I have to unplug the monitor cable and plug it back in to see the game. Then when I quit the game I have to do it again to see the desktop. UPDATE 2: Today I bought a HDMI cable, connected the video card to the TV am testing it with and it actually did log in correctly without any black screen but it shows the resolution a little over the actual size of the screen. So I see only half of the launcher since the left side of it is hidden outside of the real resolution and the top bar is beyond the resolution. So the black screen is related to the VGA connection.

  • Apache doesn't load .php files

    - by Haddex
    First, sorry for my English and asking something that it's quite answered all over the web. I've read a lot of post about this problem but I still can't find the solution. I'm a web developer who recently moved to Ubuntu from Windows 7. I had a website done (it's online and working) and I set up LAMP to keep working with it. I made a test.php file with: <?php phpinfo(); ?> and put it on /var/www/html directory, it shows all the information about the php and I was really happy: "Ok, it's all done, tomorrow I will work hard" But I placed my whole web into /var/www/html , not in a folder, the index.php is in /var/www/html but guess what: doesn't load any of my .php files, the browser just keep thinking. What I did: I rebooted Apache: /etc/init.d/apache2 restart I tried again with the test.php file and it works fine I put in /var/www/html a .html file and works fine. I looked for /etc/apache2/sites-enable/000-default.conf and it says: DocumentRoot /var/www/html I looked for /etc/apache2/mods-enabled/dir.conf and it says: DirectoryIndex index.html index.cgi index.pl index.php ... Edit* I think it's something related to phpmyadmin, like if I'm not able to connect with the database. But I got nothing on the screen when trying to load the page so...I'm not sure. I can access to the url localhost/phpmyadmin and I edited the connection.php file like this: <?php # FileName="Connection_php_mysql.htm" # Type="MYSQL" # HTTP="true" $hostname_rakstadconnection = "localhost"; $database_rakstadconnection = "rakstadclandb"; $username_rakstadconnection = "root"; $password_rakstadconnection = "admin"; $rakstadconnection = mysql_connect($hostname_rakstadconnection, $username_rakstadconnection, $password_rakstadconnection) or trigger_error(mysql_error(),E_USER_ERROR); mysql_query("SET NAMES 'utf8'"); ?> The name of the database is correct, like the user and password. http://i89.photobucket.com/albums/k220/Haddex/Capturadepantallade2014-06-09112609_zpsc45ddb72.png http://i89.photobucket.com/albums/k220/Haddex/Capturadepantallade2014-06-09112120_zps0b9e15f7.png *Edit2: could this be because it's a website that I brought to Linux from Windows? I used Dreamweaver. Edit3: I changed the # to /*/, nothing. The error.log file says: [Mon Jun 09 17:08:13.627881 2014] [:error] [pid 1517] [client 127.0.0.1:46663] PHP Warning: require_once(/var/www/html/Connections/rakstadconnection.php): failed to open stream: Permission denied in /var/www/html/index.php on line 1 [Mon Jun 09 17:08:13.627933 2014] [:error] [pid 1517] [client 127.0.0.1:46663] PHP Fatal error: require_once(): Failed opening required 'Connections/rakstadconnection.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/html/index.php on line 1 I'm reading error log but...should I add a linux path into a my index.php file? Don't think so. Thanks.

  • Apache URL rewriting in reverse proxy

    - by Jeremy Gooch
    I'm deploying Apache in front of a Karaf-hosted application (Apache and Karaf are on separate servers). I want Apache to operate as a reverse proxy and also to hide part of the URL. The URL to get the log-in page of the application directly from the app server is http://app-server:8181/jellyfish. Pages are served by the Jetty instance running within Karaf. Of course, this behaviour would usually be blocked by the firewall for everything except the reverse proxy server. With the firewall off, if you hit this URL then Jetty loads the log-in page. The browser's address bar correctly changes to http://app-server:8181/jellyfish/login?0 and everything works. What I want is for http://web-server (i.e. from the root) to map to Jetty on the app server with the name of the app (jellyfish) suppressed. e.g. The browser would change to show http://web-server/login?0 in the address bar and all subsequent URLs and content would be served with the web-server's domain and without the jellyfish clutter. I can get Apache to operate as a simple reverse proxy, using the following config (snippet):- ProxyPass /jellyfish http://app-server:8181/jellyfish ProxyPassReverse / http://app-server:8181/ ...but this requires the browser's URL to contain jellyfish and going to the root URL (http://web-server) gives a 404 Not Found. I've spent a lot of time trying to use mod_rewrite with and without its [P] flag to get around this, but without success. I then tried the ProxyPassMatch directive, but I can't seem to get that quite correct either. Here's the current config, as is loaded into /etc/apache2/sites-available/ on the web server. Note that there is a locally-hosted images directory. I've also kept the mod_rewrite proxy exploit protection and am suppressing a couple of mod_security rules that were giving false positives. <VirtualHost *:80> ServerAdmin admin@drummer-server ServerName drummer-server ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn CustomLog ${APACHE_LOG_DIR}/access.log combined Alias /images/ "/var/www/images/" RewriteEngine On RewriteCond %{REQUEST_URI} !^$ RewriteCond %{REQUEST_URI} !^/ RewriteRule .* - [R=400,L] ProxyPass /images ! ProxyPassMatch ^/(.*) http://granny-server:8181/jellyfish/$1 ProxyPassReverse / http://granny-server:8181/jellyfish ProxyPreserveHost On SecRuleRemoveById 981059 981060 <Directory "/var/www/images"> Options Indexes MultiViews FollowSymLinks AllowOverride None Order allow,deny Allow from all </Directory> </VirtualHost> If I go to http://web-server, I get redirected to http://web-server/jellyfish/home but this gives a 404, with a complaint about trying to access /jellyfish/jellyfish/home - NB the browser's address bar does not contain the double /jellyfish. HTTP ERROR 404 Problem accessing /jellyfish/jellyfish/home. Reason: Not Found And, if I go to http://web-server/login, I get redirected to http://web-server/jellyfish/login?0 but this gives a 404, with a complaint about trying to access /jellyfish/jellyfish/login. HTTP ERROR 404 Problem accessing /jellyfish/jellyfish/login. Reason: Not Found So, I'm guessing I'm somehow passing through the rules twice. I am also slightly bemused as to where the home bit of the URL comes from in the first example. Can someone point me in the right direction, please? Thanks, J.

  • Please Help Me Install Firestorm?

    - by Elle Caszatt
    I have been trying for hours just to install one program. In this time, I've tried my best to follow directions and not screw everything up but I have. I'm new to Linux. I tried to install Firestorm and this is what happened: parent@ubuntu:~$ sudo '/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh' [sudo] password for parent: Enter the desired installation directory [/opt/firestorm-install]: /home/parent/downloads - Installing to /home/parent/downloads /home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh: line 80: /home/parent/downloads/etc/refresh_desktop_app_entry.sh: Permission denied parent@ubuntu:~$ sudo opt/firestorm-install sudo: opt/firestorm-install: command not found parent@ubuntu:~$ ./etc/refresh_desktop_app_entry.sh bash: ./etc/refresh_desktop_app_entry.sh: No such file or directory parent@ubuntu:~$ sudo '/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/install.sh' Enter the desired installation directory [/opt/firestorm-install]: /home/parent - Backing up previous installation to /home/parent.backup-2012-08-27 - Installing to /home/parent cp: cannot stat `/home/parent/Downloads/Phoenix_Firestorm-Release_i686_4.2.1.29803/*': No such file or directory Failed parent@ubuntu:~$ Now whenever I go into my files it says it can't find anything. Like Cannot find home/parent/Downloads. Now, I KNOW there are downloads. I don't know why it's doing this all of a sudden. I'm so frustrated that I'm ready to just go back to Windows. I've already had to uninstall/reinstall Ubuntu once today. It's looking like I"m going to have to do it again. How can I fix my file problem that I'm now having and can someone please, please tell me how to install Firestorm? I mean they don't even have their repository listed. It's ridiculous to have to go through this over a program. Spotify wasn't hard at all to install so why is this? Someone please help, and I'm sorry if I sound like a total idiot. I'm pretty tech savvy but I'm honestly pretty upset after struggling with this for hours. Edit Okay, I see the problem with the directory files (showing the error I mentioned above when I try to click on them). I can only access my downloads, desktop, ect, through the backup that was created when I tried to install Firestorm. It's like that's the real home now. How can I get it back to the way it was? Edit Ubuntu has stopped working for me on reboot now. It doesn't go past the login screen. This is exactly what happened when I had to uninstall it before after trying to install Firestorm. Maybe I'm giving up too easily but I think I'm just going to go back to Windows. If this is what's going to happen every time I innocently try to install a program then it's just not worth it. I installed it specifically to run Firestorm because Windows sucks up a lot of CPU and causes lag. I still appreciate any input but this is just too much hassle for something that shouldn't be hard.

  • Cannot connect to website - SSL handshaking fails

    - by ravenspoint
    So I cannot connect to certain websites. Just a few, most are OK. The one I really care about is paypal.com. I have done the usual things. Let's see: Checked my etc/hosts Flushed the DNS cache Checked firewall Switched on & off virus protection Switched on and off ad blocking pinged the sites Eventually, I decided to look at what curl is saying in detail == Info: About to connect() to www.paypal.com port 443 (#0) == Info: Trying 66.211.169.2... == Info: connected == Info: SSLv3, TLS handshake, Client hello (1): => Send SSL data, 110 bytes (0x6e) 0000: 01 00 00 6a 03 01 4f 6c aa 8c 57 2b 3d 1e 74 64 ...j..Ol..W+=.td 0010: c1 27 25 a5 3a 12 7f 3f 41 0a 17 15 2e c9 67 7c .'%.:.?A.....g| 0020: b3 e1 f6 9a db a9 00 00 2a 00 39 00 38 00 35 00 ........*.9.8.5. 0030: 16 00 13 00 0a 00 33 00 32 00 2f 00 07 00 05 00 ......3.2./..... 0040: 04 00 15 00 12 00 09 00 14 00 11 00 08 00 06 00 ................ 0050: 03 00 ff 01 00 00 17 00 00 00 13 00 11 00 00 0e ................ 0060: 77 77 77 2e 70 61 79 70 61 6c 2e 63 6f 6d www.paypal.com (hangs here for ever) This looks to me like paypal is refusing to reply to the first SSL handshake. I don't know much about SSL, but compaing to the output from a site that works for me seems to make it obvious == Info: About to connect() to www.cibc.com port 443 (#0) == Info: Trying 159.231.80.200... == Info: connected == Info: SSLv3, TLS handshake, Client hello (1): => Send SSL data, 108 bytes (0x6c) 0000: 01 00 00 68 03 01 4f 6c ad 6a 1f 67 d5 84 c4 4b ...h..Ol.j.g...K 0010: 0d 49 ae d6 b9 5b c3 63 f9 48 aa 18 da 43 d1 32 .I...[.c.H...C.2 0020: 47 ae 17 e5 cd e9 00 00 2a 00 39 00 38 00 35 00 G.......*.9.8.5. 0030: 16 00 13 00 0a 00 33 00 32 00 2f 00 07 00 05 00 ......3.2./..... 0040: 04 00 15 00 12 00 09 00 14 00 11 00 08 00 06 00 ................ 0050: 03 00 ff 01 00 00 15 00 00 00 11 00 0f 00 00 0c ................ 0060: 77 77 77 2e 63 69 62 63 2e 63 6f 6d www.cibc.com == Info: SSLv3, TLS handshake, Server hello (2): <= Recv SSL data, 74 bytes (0x4a) 0000: 02 00 00 46 03 01 00 00 58 cf 26 e2 e1 65 db 11 ...F....X.&..e.. 0010: bc 6f 26 7b 3b 6d eb 14 5f ad 47 dd 86 ea 4d a3 .o&{;m.._.G...M. 0020: fb 9f b7 2a 54 3e 20 5f 6b 04 5a 12 38 64 5d 18 ...*T> _k.Z.8d]. 0030: 65 9e e9 cd 61 eb 91 c1 16 25 61 30 bb 08 2a 78 e...a....%a0..*x 0040: b8 ee b8 7e f2 65 6a 00 04 00 ...~.ej... == Info: SSLv3, TLS handshake, CERT (11): ... and so on - working nicely eventually get some nice HTML Now I am reaaly stuck. This has been going on for five days, so I am pretty sure that the problem is not with paypal. But what on my system could be interfering with the SSL handshaking done by curl with this particular site? I suppose I could not be offering any certificates that PayPal accepts, but wouldn't I get a reply telling me so, or at least giving an error?

  • Microsoft Azure News: Capturing VM Images

    - by Herve Roggero
    Originally posted on: http://geekswithblogs.net/hroggero/archive/2014/05/21/microsoft-azure-news-capturing-vm-images.aspxIf you have a Virtual Machine (VM) in Microsoft Azure that has a specific configuration, it used to be difficult to clone that VM. You had to sysprep the VM, and clone the data disks. This was slow, prone to errors, and stopped you from being productive. No more! A new option, called Capture, allows you to easily select a VM, running or not. The capture will copy the OS disk and data disks and create a new image out of it automatically for you. This means you can now easily clone an entire VM without affecting productivity.  To capture a VM, simply browse to your Virtual Machines in the Microsoft Azure management website, select the VM you want to clone, and click on the Capture button at the bottom. A window will come up asking to name your image. It took less than 1 minute for me to build a clone of my server. And because it is stored as an image, I can easily create a new VM with it. So that’s what I did… And that took about 5 minutes total.  That’s amazing…  To create a new VM from your image, click on the NEW icon (bottom left), select Compute/Virtual Machine/From Gallery, and select My Images from the left menu when selecting an Image. You will find your newly created image. Because this is a clone, you will not be prompted for a new login; the user id/password is the same.

  • How to Add a Taskbar to the Desktop in Ubuntu 14.04

    - by Lori Kaufman
    If you’ve switched to Ubuntu from Windows, it may take some time to get used to the new and different interface. However, you can easily incorporate a familiar Windows feature, the Taskbar, into Ubuntu to make the transition easier. A tool called Tint2 provides a bar at the bottom of the Ubuntu Desktop that resembles the Windows Taskbar. We will show you how to install it and make it start every time you log into Ubuntu. NOTE: When we say to type something in this article and there are quotes around the text, DO NOT type the quotes, unless we specify otherwise. Press Ctrl + Alt + T to open a Terminal window. To install Tint2, type the following line at the prompt and press Enter. sudo apt-get install tint2 Type your password at the prompt and press Enter. The progress of the installation displays and then a message displays saying how much disk space will be used. When asked if you want to continue, type a “y” and press Enter. When the installation has finished, close the Terminal window by typing “exit” at the prompt and pressing Enter. Click the Search button at the top of the Unity bar. Start typing “startup applications” in the Search box. Items that match what you type start displaying below the Search box. When the Startup Applications tool displays, click the icon to open it. On the Startup Applications Preferences window, click Add. On the Add Startup Program dialog box, enter a name for the startup application. This name displays in the list on the Startup Applications Preferences window. Type “tint2” in the Command edit box, enter a description in the Comment edit box, if desired, and click Add. Tint2 is added as a startup program and will start every time you log into Ubuntu. Click Close to close the Startup Applications Preferences window. Log out and log back in to make the Taskbar available on the desktop. You do not need to reboot the computer for this change to take effect. Now, when you minimize a program, an icon for it displays on the Taskbar at the bottom of the screen, just like the Taskbar in Windows. If you decide that you don’t want the Taskbar to display every time you log into Ubuntu, you can uncheck the Tint2 startup program on the Startup Applications Preferences window. You don’t need to delete it from the list.

  • How do I maintain a really poorly written code base?

    - by onlineapplab.com
    Recently I got hired to work on existing web application because of NDA I'm not at liberty to disclose any details but this application is working online in sort of a beta testing stage before official launch. We have a few hundred users right now but this number is supposed to significantly increase after official launch. The application is written in PHP (but it is irrelevant to my question) and is running on a dual xeon processor standalone server with severe performance problems. I have seen a lot of bad PHP code but this really sets new standards, especially knowing how much time and money was invested in developing it. it is as badly coded as possible there is PHP, HTML, SQL mixed together and code is repeated whenever it is necessary (especially SQL queries). there are not any functions used, not mentioning any OOP there are four versions of the app (desktop, iPhone, Android + other mobile) each version has pretty much the same functionality but was created by copying the whole code base, so now there are some differences between each version and it is really hard to maintain the database is really badly designed, which is causing severe performance problems also for fixing some errors in PHP code there is a lot of database triggers used which are updating data on SELECT and on INSERT so any testing is a nightmare Basically, any sin of a bad programming you can imagine is there for example it is not only possible to use SQL injections in literally every place but you can log into app if you use a login which doesn't exist and an empty password. The team which created this app is not working on it any more and there is an outsourced team which suggested that there are some problems but was never willing to deal with the elephant in the room partially because they've got a very comfortable contract and partially due to lack of skills (just my opinion). My job was supposed to be fixing some performance problems and extending existing functionality but first thing I was asked to do was a review of the existing code base. I've made my review and it was quite a shock for the management but my conclusions were after some time finally confirmed by other programmers. Management made it clear that it is not possible to start rewriting this app from scratch (which in my opinion should be done). We have to maintain its operable state and at the same time fix performance errors and extend the functionality. My question is, as I don't want just to patch the existing code, how to transform this into properly written app while keeping the existing code working at the same time? My plan is: Unify four existing versions into common code base (fixing only most obvious errors). Redesign db and use triggers to populate it with data (so data will be maintained in two formats at the same time) All new functionality will be written as separate project. Step by step transfer existing functionality into the new project After some time everything will be in the new project Some explanation about #2, right now it is practically impossible to make any updates in existing db any change requires reviewing whole code and making changes in many places. Is such plan feasible at all? Another solution is to walk away and leave the headache to someone else.

  • Squid not caching files (Randomly)

    - by Heinrich
    I want to use an intercepting squid server to cache specific large zip files that users in my network download frequently. I have configured squid on a gateway machine and caching is working for "static" zip files that are served from an Apache web server outside our network. The files that I want to have cached by squid are zip files 100MB which are served from a heroku-hosted Rails application. I set an ETag header (SHA hash of the zip file on the server) and Cache-Control: public header. However, these files are not cached by squid. This, for example, is a request that is not cached: $ curl --no-keepalive -v -o test.zip --header "X-Access-Key: 20767ed397afdea90601fda4513ceb042fe6ab4e51578da63d3bc9b024ed538a" --header "X-Customer: 5" "http://MY_APP.herokuapp.com/api/device/v1/media/download?version=latest" * Adding handle: conn: 0x7ffd4a804400 * Adding handle: send: 0 * Adding handle: recv: 0 ... > GET /api/device/v1/media/download?version=latest HTTP/1.1 > User-Agent: curl/7.30.0 > Host: MY_APP.herokuapp.com > Accept: */* > X-Access-Key: 20767ed397afdea90601fda4513ceb042fe6ab4e51578da63d3bc9b024ed538a > X-Customer: 5 > 0 0 0 0 0 0 0 0 --:--:-- 0:00:09 --:--:-- 0< HTTP/1.1 200 OK * Server Cowboy is not blacklisted < Server: Cowboy < Date: Mon, 18 Aug 2014 14:13:27 GMT < Status: 200 OK < X-Frame-Options: SAMEORIGIN < X-Xss-Protection: 1; mode=block < X-Content-Type-Options: nosniff < ETag: "95e888938c0d539b8dd74139beace67f" < Content-Disposition: attachment; filename="e7cce850ae728b81fe3f315d21a560af.zip" < Content-Transfer-Encoding: binary < Content-Length: 125727431 < Content-Type: application/zip < Cache-Control: public < X-Request-Id: 7ce6edb0-013a-4003-a331-94d2b8fae8ad < X-Runtime: 1.244251 < X-Cache: MISS from AAA.fritz.box < Via: 1.1 vegur, 1.1 AAA.fritz.box (squid/3.3.11) < Connection: keep-alive In the logs squid is reporting a TCP_MISS.

What could be wrong here?

  • Combining Shared Secret and Certificates

    - by Michael Stephenson
    As discussed in the introduction article this walkthrough will explain how you can implement WCF security with the Windows Azure Service Bus to ensure that you can protect your endpoint in the cloud with a shared secret but also combine this with certificates so that you can identify the sender of the message.   Prerequisites As in the previous article before going into the walk through I want to explain a few assumptions about the scenario we are implementing but to keep the article shorter I am not going to walk through all of the steps in how to setup some of this. In the solution we have a simple console application which will represent the client application. There is also the services WCF application which contains the WCF service we will expose via the Windows Azure Service Bus. The WCF Service application in this example was hosted in IIS 7 on Windows 2008 R2 with AppFabric Server installed and configured to auto-start the WCF listening services. I am not going to go through significant detail around the IIS setup because it should not matter in relation to this article however if you want to understand more about how to configure WCF and IIS for such a scenario please refer to the following paper which goes into a lot of detail about how to configure this. The link is: http://tinyurl.com/8s5nwrz   Setting up the Certificates To keep the post and sample simple I am going to use the local computer store for all certificates but this bit is really just the same as setting up certificates for an example where you are using WCF without using Windows Azure Service Bus. In the sample I have included two batch files which you can use to create the sample certificates or remove them. Basically you will end up with: A certificate called PocServerCert in the personal store for the local computer which will be used by the WCF Service component A certificate called PocClientCert in the personal store for the local computer which will be used by the client application A root certificate in the Root store called PocRootCA with its associated revocation list which is the root from which the client and server certificates were created   For the sample Im just using development certificates like you would normally, and you can see exactly how these are configured and placed in the stores from the batch files in the solution using makecert and certmgr.   The Service Component To begin with let's look at the service component and how it can be configured to listen to the service bus using a shared secret but to also accept a username token from the client. In the sample the service component is called Acme.Azure.ServiceBus.Poc.Cert.Services. It has a single service which is the Visual Studio template for a WCF service when you add a new WCF Service Application so we have a service called Service1 with its Echo method. Nothing special so far!.... The next step is to look at the web.config file to see how we have configured the WCF service. In the services section of the WCF configuration you can see I have created my service and I have created a local endpoint which I simply used to do a little bit of diagnostics and to check it was working, but more importantly there is the Windows Azure endpoint which is using the ws2007HttpRelayBinding (note that this should also work just the same if your using netTcpRelayBinding). The key points to note on the above picture are the service behavior called MyServiceBehaviour and the service bus endpoints behavior called MyEndpointBehaviour. We will go into these in more detail later.   The Relay Binding The relay binding for the service has been configured to use the TransportWithMessageCredential security mode. This is the important bit where the transport security really relates to the interaction between the service and listening to the Azure Service Bus and the message credential is where we will use our certificate like we have specified in the message/clientCrentialType attribute. Note also that we have left the relayClientAuthenticationType set to RelayAccessToken. This means that authentication will be made against ACS for accessing the service bus and messages will not be accepted from any sender who has not been authenticated by ACS.   The Endpoint Behaviour In the below picture you can see the endpoint behavior which is configured to use the shared secret client credential for accessing the service bus and also for diagnostic purposes I have included the service registry element.     Hopefully if you are familiar with using Windows Azure Service Bus relay feature the above is very familiar to you and this is a very common setup for this section. There is nothing specific to the username token implementation here. The Service Behaviour Now we come to the bit with most of the certificate stuff in it. When you configure the service behavior I have included the serviceCredentials element and then setup to use the clientCertificate check and also specifying the serviceCertificate with information on how to find the servers certificate in the store.     I have also added a serviceAuthorization section where I will implement my own authorization component to perform additional security checks after the service has validated that the message was signed with a good certificate. I also have the same serviceSecurityAudit configuration to log access to my service. My Authorization Manager The below picture shows you implementation of my authorization manager. WCF will eventually hand off the message to my authorization component before it calls the service code. This is where I can perform some logic to check if the identity is allowed to access resources. In this case I am simple rejecting messages from anyone except the PocClientCertificate.     The Client Now let's take a look at the client side of this solution and how we can configure the client to authenticate against ACS but also send a certificate over to the service component so it can implement additional security checks on-premise. I have a console application and in the program class I want to use the proxy generated with Add Service Reference to send a message via the Azure Service Bus. You can see in my WCF client configuration below I have setup my details for the azure service bus url and am using the ws2007HttpRelayBinding.   Next is my configuration for the relay binding. You can see below I have configured security to use TransportWithMessageCredential so we will flow the token from a certificate with the message and also the RelayAccessToken relayClientAuthenticationType which means the component will validate against ACS before being allowed to access the relay endpoint to send a message.     After the binding we need to configure the endpoint behavior like in the below picture. This contains the normal transportClientEndpointBehaviour to setup the ACS shared secret configuration but we have also configured the clientCertificate to look for the PocClientCert.     Finally below we have the code of the client in the console application which will call the service bus. You can see that we have created our proxy and then made a normal call to a WCF in exactly the normal way but the configuration will jump in and ensure that a token is passed representing the client certificate.     Conclusion As you can see from the above walkthrough it is not too difficult to configure a service to use both a shared secret and certificate based token at the same time. This gives you the power and protection offered by the access control service in the cloud but also the ability to flow additional tokens to the on-premise component for additional security features to be implemented. Sample The sample used in this post is available at the following location: https://s3.amazonaws.com/CSCBlogSamples/Acme.Azure.ServiceBus.Poc.Cert.zip

  • [EF + Oracle] Intro

    - by JTorrecilla
    Prologue I have a busy personal and working time, and at this moment that I start to get more free time, I decided to start a Serie about Entity Framework with Oracle. A few time ago, I got my first experience with EF and Oracle with Oracle 10 g express and Oracle 10 g with the same results, Doesn’t work. Now I download Oracle 11 g to Test again. Tools To start using EF with Oracle we need the following: 1. Visual Studio 2010. No Express Edition 2. Oracle 11g 3 Oracle Driver for EF (ODAC) Intro People, who are starting with EF developments, I recommend to take a look into Unai Zorrilla’s Blog, the post were written in Spanish but they are great! To this Serie, we are going to define the DB from the Oracle administrator. For that we need to follow the next steps: 1. Create a User with a PassWord. In my example the user will be Jtorrecilla 2. Create a TableSpace 3. Define some example tables   (Image1) When we have created the DB, we are going to start a new project in VS 2010. I will start a C# Project. To start with EF, we need to add a new objet to our Project “ADO .NET Entity Data Model". (Image2) The next step will be to indicate that our model will be based on an existing DB, and indicate the connection string (Images 3 and 4): (Imagen3) (Imagen4) Once we selected the connection string, we will need to indicate that in the connection will be saved “Sensitive” data (Image 5), and in the next step we are going to select the DB objets to use in the project(Image 6).   (Image 5) (Image 6) A the end of the selection, we will press Finish button, and it will generate a EDMX file to add to our solution, and in the IDE will appear the DB Schema with the selected Tables and Relations. (Imagen7) One Entity is composed by a set of properties (each matches with a column from the Table in the DB) and Navigation Properties that represents any relation with other Entities.   Finally With this chapter we have installed the environment, defined a DB and configured the solution to start using EF with Oracle. In the next chapter we are going to see What is a Entity and how it works. I hope you enjoy this Serie!

  • Best Practices for serializing/persisting String Object Dictionary entities

    - by Mark Heath
    I'm noticing a trend towards using a dictionary of string to object (or sometimes string to string), instead of strongly typed objects. For example, the new Katana project makes heavy use of IDictionary<string,object>. This approach avoids the need to continually update your entity classes/DTOs and the database tables that persist them with new properties. It also avoids the need to create new derived entity types to support new types of entity, since the Dictionary is flexible enough to store any arbitrary properties. Here's a contrived example: class StorageDevice { public int Id { get; set; } public string Name { get; set; } } class NetworkShare : StorageDevice { public string Path { get; set; } public string LoginName { get; set; } public string Password { get; set; } } class CloudStorage : StorageDevice { public string ServerUri { get; set } public string ContainerName { get; set; } public int PortNumber { get; set; } public Guid ApiKey { get; set; } } versus: class StorageDevice { public IDictionary<string, object> Properties { get; set; } } Basically I'm on the lookout for any talks, books or articles on this approach, so I can pick up on any best practices / difficulties to avoid. Here's my main questions: Does this approach have a name? (only thing I've heard used so far is "self-describing objects") What are the best practices for persisting these dictionaries into a relational database? Especially the challenges of deserializing them successfully with strongly typed languages like C#. Does it change anything if some of the objects in the dictionary are themselves lists of strongly typed entities? Should a second dictionary be used if you want to temporarily store objects that are not to be persisted/serialized across a network, or should you use some kind of namespacing on the keys to indicate this?
