• Database design for very large amount of data

  - by Hossein

  Hi, I am working on a project, involving large amount of data from the delicious website.The data available is at files are "Date,UserId,Url,Tags" (for each bookmark). I normalized my database to a 3NF, and because of the nature of the queries that we wanted to use In combination I came down to 6 tables....The design looks fine, however, now a large amount of data is in the database, most of the queries needs to "join" at least 2 tables together to get the answer, sometimes 3 or 4. At first, we didn't have any performance issues, because for testing matters we haven't had added too much data in the database. No that we have a lot of data, simply joining extremely large tables does take a lot of time and for our project which has to be real-time is a disaster.I was wondering how big companies solve these issues.Looks like normalizing tables just adds complexity, but how does the big company handle large amounts of data in their databases, don't they do the normalization? thanks

• replace file with hardlink to another file atomically

  - by Ben Clifford

  I have two directory entries, a and b. Before, a and b point to different inodes. Afterwards, I want b to point to the same inode as a does. I want this to be safe - by which I mean if I fail somewhere, b either points to its original inode or the a inode. most especially I don't want to end up with b disappearing. mv is atomic when overwriting. ln appears to not work when the destination already exists. so it looks like i can say: ln a tmp mv tmp b which in case of failure will leave a 'tmp' file around, which is undesirable but not a disaster. Is there a better way to do this? (what I'm actually trying to do is replace files that have identical content with a single inode containing that content, shared between all directory entries)

• Postgresql - one database for everyone, or one-database per customer

  - by user337876

  I'm working on a web-based business application where each customer will need to have their own data (think basecamphq.com type model) For scalability and ease-of-upgrades, I'd prefer to have a single database where each customer gets a filtered version of the data. The problem is how to guarantee that they stay sandboxed to their own data. Trying to enforce it in code seems like a disaster waiting to happen. I know Oracle has a way to append a where clause to every query based on a login id, but does Postgresql have anything similar? If not, is there a different design pattern I could use (like creating a view of each table for each customer that filters)? Worse case scenario, what is the performance/memory overhead of having 1000 100M databases vs having a single 1Tb database? I will need to provide backup/restore functionality on a per-customer basis which is dead-simple on a single database but quite a bit trickier if they are sharing the database with other customers.

• Repeated Scene Trees (Java3d / OpenGL)

  - by Jim

  Hello, I want to make a 3d scene that loops around on its self. That is to say, if you keep going in any direction, you will loop back to the other side. My current implementation is so bad, it's embarrassing to admit to it. I redraw the each change twenty-seven times, to make a 3x3x3 scene cube. When the user reaches the end of the middle cube, I jump them over to the other side. Maintaining consistency (let alone performance) is a nightmare. Total Disaster. This doesn't seem like it would be an unusual request, so I'm wondering if anyone knows of a more legit solution. Thanks!

• Git on windows :|

  - by Sonic Soul

  i've been experimenting with git as my personal code rep.. and it has been a bit of a disaster with windows. i've used Subversion, CVS, and Perforce in the past.. none were as annoying to use as git. i've figured out the PGP part (for github), although my workstation no longer lets me check in, and after searching around it turns out that git bash is using putty which is not that reliable and should be configured with something else.. i was not able to configure it with windows shell extension for a nice visual of what is part of the repository, what is modified, and easy check ins, and easy pushes.. has anyone successfully configured some kind of windows shell client and can efficiently and quickly synchronize various machines? It just seems to be more pain to use than it is worth..

• How to secure licensekey generation

  - by Jakob Gade

  Scenario, simplified for brevity: A developer creates an application for a customer. The customer sells this app to end-users. The app requires a license key to run, and this key is generated by the customer for each end-user with a simple tool created by the developer. The license key contains an expiry date for the license and is encrypted so the end-user can’t tamper with it. The problem here is that the developer (or anybody who has a copy of the license key generator) can easily create valid license keys. Should this generator fall into the wrong hands, it could spell disaster for the customers business. Ideally, the customer would have to use a password to create new license keys. And this password would be unknown to the developer, and somehow baked into the decryption algorithm in the application so it will fail if an attempt to use an unauthorized key is made. How would you implement a solution for this problem that is both transparent and secure?

• How is dynamic memory allocation handled when extreme reliability is required?

  - by sharptooth

  Looks like dynamic memory allocation without garbage collection is a way to disaster. Dangling pointers there, memory leaks here. Very easy to plant an error that is sometimes hard to find and that has severe consequences. How are these problems addressed when mission-critical programs are written? I mean if I write a program that controls a spaceship like Voyager 1 that has to run for years and leave a smallest leak that leak can accumulate and halt the program sooner or later and when that happens it translates into epic fail. How is dynamic memory allocation handled when a program needs to be extremely reliable?

• Why would you want a case sensitive database?

  - by Khorkrak

  What are some reasons for choosing a case sensitive collation over a case insensitive one? I can see perhaps a modest performance gain for the DB engine in doing string comparisons. Is that it? If your data is set to all lower or uppercase then case sensitive could be reasonable but it's a disaster if you store mixed case data and then try to query it. You have then apply a lower() function on the column so that it'll match the corresponding lower case string literal. This prevents index usage in every dbms. So wondering why anyone would use such an option.

• If you can't do a Support Role, does this mean you should not be in development?

  - by Alex

  Hi, I've been shifted around roles a lot, and have been put in a support role which seems to deal out a lot of rubbish due to poor business management. Anyway, my line manager says that he's not sure he would recommend me for a developer role as they regard support as a poor technical role. What I resent is the fact that not all the information is available to us about what we're supporting and I miss coding. This thing I'm supporting has been regarded as a disaster when it went in and is still highly unstable. The thing is...does he have a point about Support roles being under developers, or are they completely two different kettle of fish?

• is JsonP working with Opera, Chrome & Safari ?

  - by Tom

  Hi, On a web site that I am building , when you log in (because the database is on an other server), I use json padding to check if the user as the right credentials. It's working flawlessly (ie7,ie8 & FF), until I tried it on chrome, safari & opera where it's a complete disaster. $.ajax({ type: "GET", dataType: "jsonp", url: "http://someurl.com", data: aRequestData, cache: false, error: function (XMLHttpRequest, textStatus, errorThrown) { // typically only one of textStatus or errorThrown // will have info alert("Error occured textStatus=" + textStatus + " errorThrown=" + errorThrown); }, success: function(data) { alert('success'); } }); Plain and simple and it works in browser window, however, to my big surprise it did not work in chrome, safari & opera, never got to the success alert. Does anyone know how to solve this issue? Thanks.

• Good programming style when handling multiple objects

  - by Glitch

  I've been programming a software version of a board game. Thus far I have written the classes which will correspond to physical objects on the game board. I'm well into writing the program logic, however I've found that many of the logic classes require access to the same objects. At first I was passing the appropriate objects to methods as they were called, but this was getting very tedious, particularly when the methods required many objects to perform their tasks. To solve this, I created a class which initialises and stores all the objects I need. This allows me to access an object from any class by calling Assets.dice(), for example. But now that I've thought about it, this doesn't seem right. This is why I'm here, I fear that I've created some sort of god class. Is this fear unfounded, or have I created a recipe for disaster?

• New hire expectations... (Am I being unreasonable?)

  - by user295841

  I work for a very small custom software shop. We currently consist me and my boss. My boss is an old FoxPro DOS developer and OOP makes him uncomfortable. He is planning on taking a back seat in the next few years to hopefully enjoy a “partial retirement”. I will be taking over the day to day operations and we are now desperately looking for more help. We tried Monster.com, Dice.com, and others a few years ago when we started our search. We had no success. We have tried outsourcing overseas (total disaster), hiring kids right out of college (mostly a disaster but that’s where I came from), interns (good for them, not so good for us) and hiring laid off “experienced” developers (there was a reason they were laid off). I have heard hiring practices discussed on podcasts, blogs, etc... and have tried a few. The “Fizz Buzz” test was a good one. One kid looked physically ill before he finally gave up. I think my problem is that I have grown so much as a developer since I started here that I now have a high standard. I hear/read very intelligent people podcasts and blogs and I know that there are lots of people out there that can do the job. I don’t want to settle for less than a “good” developer. Perhaps my expectations are unreasonable. I expect any good developer (entry level or experienced) to be billable (at least paying their own wage) in under one month. I expect any good developer to be able to be productive (at least dangerous) in any language or technology with only a few days of research/training. I expect any good developer to be able to take a project from initial customer request to completion with little or no help from others. Am I being unreasonable? What constitutes a valuable developer? What should be expected of an entry level developer? What should be expected of an experienced developer? I realize that everyone is different but there has to be some sort of expectations standard, right? I have been giving the test project below to potential canidates to weed them out. Good idea? Too much? Too little? Please let me know what you think. Thanks.

• End User Ad-Hoc Reporting Tool: Microsoft SQL Server Management Studio or Microsoft Access?

  - by schultkl

  Our centralized IT department has suggested two primary ad hoc query tools for our general user base of approximately 200 staff members: Microsoft SQL Server Management Studio 2008 (SSMS) Microsoft Access 2003 Environment The backend database is a read-only Microsoft SQL Server 2005 database. The schema is 400+ tables; allowing access to the raw data for our general staff would be a disaster. We will be building an "abstraction layer" over the raw data for our general staff to run ad hoc queries against. The abstraction layer will most likely contain a number of views. A number of users have basic knowledge in Microsoft Access; none have used SSMS. Which of the above tools (or alternative) would be best for a decidedly non-techie user base of approximately 200 people? What are the pros and cons of each? Also, the IT department has suggested teaching people T-SQL so they may use SSMS. Is this reasonable?

• Version control of Mathematica notebooks

  - by Etaoin

  Mathematica notebooks are, of course, plaintext files -- it seems reasonable to expect that they should play nice with a version-control system (git in my case, although I doubt the specific system matters). But the fact is that any .nb file is full of cache information, timestamps, and other assorted metadata. Scads of it. Which means that limited version control is possible -- commits and rollbacks work fine. Merging, though, is a disaster. Mathematica won't open a file with merge markers in it, and a text editor is no way to go through a .nb file. Has anyone had any luck putting a notebook under version control? How?

• Premature optimization is the root of all evil, but can it ever be too late?

  - by polygenelubricants

  "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil" So what is that 3% like? Can the avoidance of premature optimization ever be taken too extreme that it does more harm than good? Even if it's rare, has there been a case of a real measurable software engineering disaster due to complete negligence to optimize early in the process? Bonus question: is software engineering pretty much the only field that has such a counter intuitive principle regarding doing something earlier rather than later before things potentially become too big a problem to fix? Personal question: how do you justify something as premature optimization and not just a case of you being lazy/ignorant/dumb?

• Will the <b> and <i> tags ever become deprecated?

  - by CrazyJugglerDrummer

  (This is more of a curiousity question than any pending disaster :D ) So the <b> and <i> tags have been around since near the beginning of the web (I assume). But now we have CSS and many people apposing "stylistic html tags." They are stylistic tags, but they're really not so bad, as they save us from having to make a <span class="bold"> a whole bunch of times, reducing download times. Seeing as they don't take up much space, are easy to use, can possibly be useful to screen-readers, search engines, and other applications that don't care much about how a document looks, and removing them would break TONS of html code, I'm guessing probably not, but I still wanted to bring up the topic. :)

• What issues carry the highest risk in a software project?

  - by Mehrdad Afshari

  Clearly, software projects are different from other industries in terms of many things like for instance, quality assurance, project progress measurement, and many other things. Unique characteristics of software projects also makes the risk management process unique. Lots of issues in a project might lead it to unacceptable delay or failure to deliver business value. They might even make a complete disaster in the project. What are the deadliest risk factors in a software project? How to analyze, prevent and handle them? Particularly, I'm interested in the issues that you can detect from the beginning and you should keep an eye on (for example, you might be told about a third-party API that the current application uses and lacks documentation). Please share your experiences if they are relevant.

• Click-Once deployment is leaving multiple versions (yes, more than 2)

  - by Clyde

  I've got a click once application that is leaving all old versions on my disk. It's an internal corporate application that gets frequent updates, so this is a disaster for rapidly inflating our backup size. According to the docs and other SO questions, it is supposed to only leave the current and previous versions on disk. However, each time I deploy the project and upgrade a client, I get another copy of all exe/dll/data files. I'm making no changes whatsoever to the application, just pushing deploy again in Visual Studio. Any ideas? Updates: The problem seems to happen on both Windows 7 and XP. 64 bit windows and 32. I've done a diff of the folders where the version is installed and the following files are different: MyApp.exe.manifest MyApp.exe.cdf-ms MyDll1.cdf-ms MyDll2.cdf-ms No actual executable files are different, nor the MyApp.manifest, MyDll1.manifest, etc.

• The Oracle Enterprise Linux Software and Hardware Ecosystem

  - by sergio.leunissen

  It's been nearly four years since we launched the Unbreakable Linux support program and with it the free Oracle Enterprise Linux software. Since then, we've built up an extensive ecosystem of hardware and software partners. Oracle works directly with these vendors to ensure joint customers can run Oracle Enterprise Linux. As Oracle Enterprise Linux is fully--both source and binary--compatible with Red Hat Enterprise Linux (RHEL), there is minimal work involved for software and hardware vendors to test their products with it. We develop our software on Oracle Enterprise Linux and perform full certification testing on Oracle Enterprise Linux as well. Due to the compatibility between Oracle Enterprise Linux and RHEL, Oracle also certifies its software for use on RHEL, without any additional testing. Oracle Enterprise Linux tracks RHEL by publishing freely downloadable installation media on edelivery.oracle.com/linux and updates, bug fixes and security errata on Unbreakable Linux Network (ULN). At the same time, Oracle's Linux kernel team is shaping the future of enterprise Linux distributions by developing technologies and features that matter to customers who deploy Linux in the data center, including file systems, memory management, high performance computing, data integrity and virtualization. All this work is contributed to the Linux and Xen communities. The list below is a sample of the partners who have certified their products with Oracle Enterprise Linux.

• Disable Opera Thumbnail Previews on Windows 7 Taskbar

  - by Asian Angel

  If you are one of the people who does not care for the Taskbar Thumbnail Previews in Windows 7 then we have a quick and easy way for you to turn them off in Opera Browser. Before Here is our Opera Browser with four tabs full of HTG Network goodness… Hovering the mouse over the Taskbar Icon gives a nice preview of each tabs content. Looking closer you can see the fanned edge on the Taskbar Icon indicating that there are multiple tabs open. This is all good but what if you just want something simpler? Disabling the Previews If you want to disable the Taskbar Thumbnail Previews in Opera you will need to type opera:config in the Address Bar and press Enter. Once you have done that, you will see a condensed listing for all of Opera’s preferences. There is one Preference Category that we need to look for…User Prefs. Note: While a Quick Find Search could be conducted for the entry that needs to be modified, we have chosen to show the full method here. After scrolling down and finding the User Prefs category you will need to expand the section. Notice the size of the scrollbar in comparison with the screenshot above…there is quite a lot that you can look at and finesse in Opera if desired. Scroll down until you find the Use Windows 7 Taskbar Thumbnails entry. Uncheck the box but do not close the opera:config Tab yet…or your changes will not take effect. Scroll down once more until you reach the end of the User Prefs category and click Save. With this particular modification you will need to restart Opera after clicking OK. After restarting Opera the Taskbar Icon and Taskbar Thumbnail Preview will revert to the minimal Windows 7 default as shown here. You can see Opera’s Tab Bar in the thumbnail and the Taskbar Icon no longer has a “fanned edge”. Conclusion If you want to disable Opera’s Taskbar Thumbnail Previews on your Windows 7 system, then this quick modification will help get it sorted out in just a few moments.

• Mark Messages As Read in the Outlook 2010 Reading Pane

  - by Matthew Guay

  Do you ever feel annoyed that Outlook 2010 doesn’t mark messages as Read as soon as you click and view them in the Reading Pane?  Here we show you how to make Outlook mark them as read as soon as they’re opened. Mark as Read By default, Outlook will not mark a message as read until you select another message.  This can be annoying, because if you read a message and immediately click Delete, it will show up as an unread message in our Deleted Items folder. Let’s change this to make Outlook mark messages as read as soon as we view them in the Reading Pane.  Open Outlook and click File to open Backstage View, and select Options. In Options select Mail on the left menu, and under Outlook panes click on the Reading Pane button. Check the box Mark items as read when viewed in the Reading Pane to make Outlook mark your messages as read when you view them in the Reading Pane.  By default, Outlook will only mark a message read after you’ve been reading it for 5 seconds, though you can change this.  We set it to 0 seconds so our messages would be marked as read as soon as we select them. Click OK in both dialogs, and now your messages will be marked as read as soon as you select them in the reading pane, or soon after, depending on your settings. Conclusion Outlook 2010 is a great email client, but like most programs it has its quirks.  This quick tip can help you get rid of one of Outlook’s annoying features, and make it work like you want it to. And, if you’re still using Outlook 2007, check out our article on how to Mark Messages as Read When Viewed in Outlook 2007.

• Cost justification for buying a 32GB superfast Alienware M18x with a price tag of around £5K ($10K)

  - by tonyrogerson

  When considering buying a laptop that’s going to cost me around £5,000 I really need to justify the purchase from a business perspective; my Lenovo W700 has served me very well for the last 2 years, it’s an extremely good machine and as solid as a rock (and as heavy), alas though it is limited to the 8GB. As SQL Server 2012 approaches and with my interest in working in the Business Intelligence space over the next year or two it is clear I need a powerful machine that I can run a full infrastructure though virtualised. My requirements For High Availability / Disaster Recovery research and demonstration Machine for a domain controller Four machines in a shared disk cluster (SQL Server Clustering active – active etc.) Five  machines in a file share cluster (SQL Server Availability Groups) For Business Intelligence research and demonstration Not entirely sure how many machine I want to run here, but it would be to cover the entire BI stack in an enterprise setting, sharepoint, sql server etc. For Big Data Research I have a fondness for the NoSQL approach to scalability and dealing with large volumes so I need a number of machines to research VoltDB, Hadoop etc. As you can see the requirements for a SQL Server consultant to service their clients well is considerable; will 8GB suffice, alas no, it will no longer do. I’m a very strong believer that in order to do your job well you must expense it, short cuts only cost you time, waiting 5 minutes instead of an hour for something to run not only saves me time but my clients time, I can do things quicker and more importantly I can demonstrate concepts. My W700 with the 8GB of RAM and SSD’s cost me around £3.5K two years ago, to be honest I’ve not got the full use I wanted out of it but the machine has had the power when I’ve needed it, it’s served me and my clients well. Alienware now do a model (the M18x) with 32GB of RAM; yes 32GB in a laptop! Dual drives so I can whack a couple of really good SSD’s in there, a quad core with hyper threading i7 and a decent speed. I can reduce the cost of the memory by getting it from Crucial, so instead of £1.5K for 32GB it will be around £900, I can also cost save on the SSD as well. The beauty about the M18x is that it is USB3.0, SATA 3 and also really importantly has eSATA, running VM’s will never be easier, I can have a removeable SSD with my VM’s on it and can plug it into my home machine or laptop – an ideal world! The initial outlay of £5K is peanuts compared to the benefits I’ll give my clients, I will be able to present real enterprise concepts, I’ll also be able to give training on those real enterprise concepts and with real, albeit virtualised machines.

• Create a Shortcut to Put Your Windows Computer into Hibernation

  - by Mysticgeek

  Putting your Windows computer into Hibernation Mode allows you to save power, and quickly access your desktop again when you need it. Here we show how to create a shortcut to put your PC in Hibernation Mode quickly. Note: Here we show how to create the shortcut in Windows 7 and add it to the Taskbar. But creating the shortcut should work in XP and Vista as well. Create Shortcut  Right-click an empty area on your desktop and select New \ Shortcut from the Context Menu. In the Create Shortcut window type or copy the following in the location field… C:\Windows\System32\rundll32.exe powrprof.dll, SetSuspendState 0,1,0 Now give the shortcut a name such as Hibernate Computer or whatever you want to call it. Now you have the shortcut on your desktop, but you might want to change the icon to something else. Change Shortcut Icon Right-click the shortcut icon and select Properties. Select the Shortcut Tab and click the Change Icon button. In the Look for icons in this file field copy and past the following then click OK. %SystemRoot%\system32\SHELL32.dll This brings up a list of included Windows icons you can choose from.
