• Should I care about Junit redundancy when using setUp() with @Before annotation?

  - by c_maker

  Even though developers have switched from junit 3.x to 4.x I still see the following 99% of the time: @Before public void setUp(){/*some setup code*/} @After public void tearDown(){/*some clean up code*/} Just to clarify my point... in Junit 4.x, when the runners are set up correctly, the framework will pick up the @Before and @After annotations no matter the method name. So why do developers keep using the same conventional junit 3.x names? Is there any harm keeping the old names while also using the annotations (other than it makes me feel like devs do not know how this really works and just in case, use the same name AND annotate as well)? Is there any harm in changing the names to something maybe more meaningful, like eachTestMethod() (which looks great with @Before since it reads 'before each test method') or initializeEachTestMethod()? What do you do and why? I know this is a tiny thing (and may probably be even unimportant to some), but it is always in the back of my mind when I write a test and see this. I want to either follow this pattern or not but I want to know why I am doing it and not just because 99% of my fellow developers do it as well.

• Performance impact of Zones.

  - by nospam(at)example.com (Joerg Moellenkamp)

  I was really astonished when i saw this question. Because this question was a old acquaintance from years ago, that i didn't heard for a long time. However there was it again. The question: "What's the overhead of Zones?". Sun was and Oracle is not saying "zero". We saying saying minimal. However during all the performance analysis gigs on customer systems i made since the introduction of Zones i failed to measure any overhead caused by zones. What i saw however, was additional load intoduced by processes that wouldn't be there when you would use only one zone Like additional monitoring daemons, like additional daemons having a controlling or supervising job for the application that resulted in slighly longer runtimes of processes, because such additional daemons wanted some cycles on the CPU as well. So i ask when someone wants to tell me that he measured a slight slowdown, if he or she has really measured the impact of the virtualization layer or of a side effect described above. It seems to be a little bit hard to believe, that a virtualisation technology has no overhead, however keep in mind that there is no hypervisor and just one kernel running that looks and behaves like many operating system instances to apps and users. While this imposes some limits to the technology (because there is just one kernel running you can't have zones with different kernels versions running ... obvious even to the cursory observer), but that is key to it's lightweightness and thus to the low overhead.

• What is the recommended way to empty a SSD?

  - by Lekensteyn

  I've just received my new SSD since the old one died. This Intel 320 SSD supports TRIM. For testing purposes, my dealer put malware, err, Windows on it. I want to get rid of it and install Kubuntu on it. It does not have to be a "secure wipe", I just need the empty the disk in the mosy healthy way. I believe that dd if=/dev/zero of=/dev/sda just fills the blocks with zeroes and thereby taking another write (correct me if I'm wrong). I've seen the answer How to enable TRIM, but it looks like it's suited for clearing empty blocks, not wiping the disk. hdparm seems to be the program to do it, but I'm not sure if it clears the disk OR cleans empty blocks. From its manual page: --trim-sector-ranges For Solid State Drives (SSDs). EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! Tells the drive firmware to discard unneeded data sectors, destroying any data that may have been present within them. This makes those sectors available for immediate use by the firmware's garbage collection mechanism, to improve scheduling for wear-leveling of the flash media. This option expects one or more sector range pairs immediately after the option: an LBA starting address, a colon, and a sector count, with no intervening spaces. EXCEPTIONALLY DANGEROUS. DO NOT USE THIS OPTION!! E.g. hdparm --trim-sector-ranges 1000:4 7894:16 /dev/sdz How can I make all blocks appear as empty using TRIM?

• What patterns book for iOS development contains this specific information? [closed]

  - by Brett Ryan

  I've read several books on iOS development and Objective-C, however what a lot of them teach is how to work with interfaces and all contain the model inside the view controller, i.e. a UITableViewController based view will simply have an NSArray as it's model. I'm interested in what the best practices are for designing the structure of an application. Specifically I'm interested in best practices for the following: How to separate a model from the view controller. I think I know how to do this by simply replacing the NSArray style example with a specific model object, however what I do not know how to do is alert the view when the model changes. For example in .NET I would solve this by conforming to INotifyPropertyChanged and databinding, and similarly with Java I would use PropertyChangeListener. How to create a service model for my domain objects. For example I want to learn the best way to create a service for a hypothetical Widget object to manage an internal DB and also services for communicating with remote endpoints. I need to learn the best ways to do this in a way that interface components can subscribe to events such as widgetUpdated. These services should be singleton classes and some how dependency injected into model/controller objects. Books I've read so far are: Programming in Objective-C (4th Edition) Beginning iOS 5 Development: Exploring the iOS SDK The iOS 5 Developer's Cookbook: Expanded Electronic Edition: Essentials and Advanced Recipes for iOS Programmers Learn Objective-C on the Mac: For OS X and iOS I've also purchased the following updated books but not yet read them. The Core iOS 6 Developer's Cookbook (4th edition Programming in Objective-C (5th Edition) I come from a Java and C# background with 15 years experience, I understand that many of the ways I would do things in these languages may not fit to the ObjC way of developing applications. Would someone be able to provide me with the book on this topic containing this specific subject matter?

• Trac/SVN to DVCS Migration

  - by quanticle

  The project I'm currently working on is using Trac, with SVN integration. It's worked great until now. Now, however, we've taken on some additional developers and we're running into issues with branching and merging. Because of this, I think a move to a distributed version control system is in order. The problem is that Trac is very closely integrated with the SVN repository. We have tight integration between the tickets and the revision numbers of code changes corresponding to those tickets. In addition we have a support wiki that has a lot of data that helps the tech. support team. Is there a way we can migrate to git or mercurial without losing the benefits of Trac? I've looked at the git plugin for Trac, and I'm unsure of how well it works. Has anyone here used it with a project that's been migrated from SVN? EDIT: I should note that the most important priority for us is maintaining the links between Trac tickets and the corresponding changesets in SVN. That's a tool that we use every day, and it provides an easy way to jump to code changes when reviewing tickets. Wiki migration would be nice to have, but if it's not possible, we can continue to run the old system whilst we write some kind of a one-off script to migrate the content.

• Ubuntu 12.04 Very slow especially with Android Studio

  - by Dew

  I have an old laptop with the following specification: Memory: 485 MiB, Processor: Genuine intel CPU T2300 @ 1.66 GHz ×2, OS Type: 32 bit, Disk: 78.1 GB, I installed on it Ubuntu 12.04 LTS and I noticed that the overall system is very slow in responding. I tried to search about that in the internet and I found some articles talking about how to make Ubuntu 12.04 LTS run fast I applied all what they said including download LXDE desktop environment and then nothing different in the system response time. Then I need to develop some android applications so, I download Android Studio (Beta) 0.8.6. The problem became worse than before whenever I tried to open the Android Studio the screen is frozen for some minutes then it took time to download the projects and initialize the work space also, when I tried to move the cursor he is move very slowly. When I tried to run my first application on the AVD it took three hours and still not run yet. I delete the Android Studio and install it again several times, I was trying to solve the problem but still nothing change. Please if you have any suggestions that may help me make my laptop and Android Studio work faster I will appreciate it for you. Thank you in advance.

• What is a good Foxit reader equivalent (or other PDF editor)?

  - by Yanick Rochon

  On Windows, I have found Foxit Reader to be quite handy when I need to highlight texts in PDF document, make annotations, etc. etc. Unfortunately, I have not yet found product as user friendly (which also does not corrupt PDF files...) and full-featured as Foxit software... Any recommendations? ** UPDATE ** I just tried the Open Office PDF import extension. It seems to work ok... If anyone used it for a while, I'd appreciate your feedback on that one. Thanks! ** UPDATE ** You can't highlight text with OpenOffice's PDF extension. Doesn't matter, I was reading this thread and found out about Xournal . As it turns out, it's in the repository. It does not natively save in PDF, but once all edits are done, the document can be exported to PDF (and overwrite the old one, just like Gimp with the native .XCE format and original PNG file, for example) I realize that this question is no longer a question in itself, but could be migrated to community wiki. However, feedbacks are still welcome! ** EDIT ** So... to close up this question, I have to say that I adopted Xournal . It is light and works pretty well, even on multi-page PDF documents. Thank you all for your answers!

• Fresh install of 64 bit 12.04 over 32 bit 11.10 alongside Windows 7

  - by Pareen

  I currently have Ubuntu 11.10 32 bit and Windows 7 dual boot in separate partitions. I am trying to do a fresh install of Ubuntu 12.04 64 bit (mistakenly installed the 32 bit 11.10 a little while ago.. I need a 64 bit version to support AOSP build) OVER my the exisiting 11.10 partition. I have referenced How to Install fresh 12.04 install to a PC with dual booting Windows 7 & Ubuntu11.10?, as well as other posts on using the Live CD to do a fresh install. However, the problem I am experiencing is when I bring up the install screen, it says the following: This computer has multiple operating systems on it. What would you like to do. (3 options) Install Ubuntu 12.04 alongside them Replace all with Ubuntu 12.04 (Warning, this will delete files across ALL operating systems) Something else (you can create or resize partitions yourself) This is different from what is in other posts, as mine states that there are "multiple O.Ses" and doesnt individually allow me to replace the Ubuntu 11.10. I don't want to replace ALL O.S.es: I need to preserve Windows 7 and am only trying to replace the old Ubuntu 11.10 partition with the new 12.04 64 bit. I did have Ubuntu installed via Wubi (I believe it was 10.04) prior to putting 11.10 in a separate partition, but I have removed it via Add/Remove programs in Windows. I was wondering how to go about doing this... Should I use the "Something else" option to bring up the partition manager, and just assign my existing 11.10 partition with root mount point + swap space. Will this do the same thing by overwriting with fresh 12.04 install?? I appreciate all your help.

• What You Said: How Do You Browse Securely Away From Home?

  - by Jason Fitzpatrick

  Responses to this week’s Ask the Reader question show that just because you’re away from home doesn’t mean you have to give up the security and privacy that your home network provides. Earlier this week we asked you to share you browsing away from home security tips and tricks and obliged. JC offered one of the more entertaining tales of away-from-home browsing: Recently a bunch of us stayed at a high end resort down in Mexico. Internet was offered as a pay per device service at about $80/week/device. Considering we had about 12 wifi devices there among us(a few geeks), I decided to plan ahead. I setup a WRT54G as a WiFi client with a vpn back to my house and NAT. Setup a second one as a basic wireless access point with password and plugged it into the first. Onsite we setup the devices and connected to the wireless with one paid account(tied to the MAC address). Everyone connected to the other device for wireless access and it was all tunnelled through my home network with encryption.

• HP G42 Ubuntu live cd failure

  - by Jon

  Ok, I have tried every option under the sun. I have surfed through the internet for a good 3 hours straight and to no effect. I installed ubuntu on my HP G42 laptop, it worked fine, then when I tried installing the standard after installation updates my wifi failed. In my attempt to fix my wi-fi I rebooted my laptop, when I rebooted I was stuck on a black screen with nothing that I tried to fix it helping the situation. So I then tried to fix it by reinstalling Ubuntu. When I attempted to boot into the live ccd it failed leaving with the now familar black screen. After numerous attempts using instructions from live cd and instal failure blank screen... page and replacing my hard drive at a cost of $65 I am coming here for help. As for the actual DVD that I tried installing ubuntu from it was able to install ubuntu on a mac just fine after my issues on the HP. After installing the hard drive I loaded up windows just fine but I don't want windows I want ubuntu, can you please provide instructions on how to install ubuntu?

• Create subdomains via C-Panel or via domain registrar?

  - by cybergeek654

  I am a novice, so excuse me if it sounds dummy. I read a few similar questions on this topic here but they did not answer my question. I have a personal website, hosted with C-panel control panel. Via C-panel I can easily create new subdomains and I do not need to apply any DNS settings or so. And the subdomian is good to go immediately and are working fine. I have unlimited subdomains option. When I check my DNS management control panel in my domain registrar's site, there is no record associated with my subdomains. Now I want to buy a new domain name from 1and1, and have it as an add-on domain in my prevouse host. 1and1 say they only allow 5 subdomains. What does this mean? Can not I create unlimited subdomains under my new domain name, just as I do for my old domain? How does C-panel create and manage subdomains that there is nothing about it in my DNS control panel? Thanks for your help

• Ubuntu 14.04 install fails with Via S3 UniChrome Pro graphics

  - by WizardNo.7

  I am trying to install Ubuntu 14.04 on a Fujitsu Siemens Amilo Pro laptop(it's quite old yes, has about 30GB Hard Drive and I think 192mb of RAM) which currently has Windows XP installed (which I'd like to keep for the time being). I have downloaded the 32-bit Desktop ISO and used unetbootin to create a Live USB for this laptop. When I boot from USB, I arrive at the unetbootin Grey and Blue menu and pick either "Try Ubuntu without installing", or "Install Ubuntu". The menu goes away and an Ubuntu loadscreen showing UBUNTU and four dots which progressively change between white and orange. At about the second color changing cycle a white underscore symbol appears next to the fourth dot and flickers. There is some leftover text from the kernel boot still visible, but there is no graphical desktop. After this I have to hard reboot or shut-down. $ lshw -c video *-display UNCLAIMED description: VGA compatible controller product: CN700/P4M800 Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro] Vendor: VIA Technologies, Inc. physical id: 0 bus info: pci@0000:01:00.0 version: 01 width: 32 bits clock: 66MHz capabilities: pm agp agp-2.0 vga_controller bus_master cap_list configuration: latency=64 mingnt=2 resources: memory:f0000000-f3ffffff memory:d1000000-d1ffffff

• Directing Multiple ccTLD's to 1 gTLD with a country specific subdirectory?

  - by Pascal Van Opzeeland

  We have multiple ccTLDomains and are thinking about how to best combine these into one. We want to do this to focus our link building efforts. We are running a website through which we offer a software-as-a-service. Therefore we could potentially sell to any country in the world. However, Germany is our most important market. We currently have a .com, .de, .nl. and .pl domain. All these domains have a high amount of unique content pages. What we are planning is to change everything to .com with language-based subdirectories, so .com/en/, .com/de/, etc. I have two questions concerning this issue: 1) How much of an advantage does a ccTLD have over a gTLD with country specific subdirectories in search rankings? So let’s say .de versus .com/de/? 2) How could we best redirect the visitors of our old ccTLD’s to our gTLD’s subdirectories? We would like to loose as few search engine rankings as possible. Thank you for your help.

• Graphics hardware warning when updating to 14.04

  - by pacomet

  As I use Ubuntu at work I just update only LTS versions but now I'm not sure if I can/should. As my computer is now ten years old I would change if was mine but as it is owned by my employer I have to work with it. It's not a bad one, it runs fine (this was not true when still had Windows on it ;-). When updating to 14.04, it warns about possible bad/slow performance with Unity 3D so I stop updating as I am at work, not my own computer. As I understand from http://askubuntu.com/a/438958/25305 Nvidia Geforce FX 5500 graphics card is still supported in 14.04. Now, in 12.04, I have driver version 173 and unity 2d runs fine for me. output of /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: GeForce FX 5500/AGP/SSE2 OpenGL version string: 2.1.2 NVIDIA 173.14.39 Not software rendered: yes Not blacklisted: no GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no Should I update? Is it better to stay with 12.04? Thanks

• What are the common techniques to handle user-generated HTML modified differently by different browsers?

  - by Jakie

  I am developing a website updater. The front end uses HTML, CSS and JavaScript, and the backend uses Python. The way it works is that <p/>, <b/> and some other HTML elements can be updated by the user. To enable this, I load the webpage and, with JQuery, convert all those elements to <textarea/> elements. Once they the content of the text area is changed, I apply the change to the original elements and send it to a Python script to store the new content. The problem is that I'm finding that different browsers change the original HTML. How do you get around this issue? What Python libraries do you use? What techniques or application designs do you use to avoid or overcome this issue? The problems I found are: IE removes the quotes around class and id attributes. For example, <img class='abc'/> becomes <img class=abc/>. Firefox removes the backslash from the line breaks: <br \> becomes <br>. Some websites have very specific display technicalities, so an insertion of a simple "\n"(which IE does) can affect the display of a website. Example: changing <img class='headingpic' /><div id="maincontent"> to <img class='headingpic'/>\n <div id="maincontent"> inserts a vertical gap in IE. The things I have unsuccessfully tried to overcome these issues: Using either JQuery or Python to remove all >\n< occurences, <br> etc. But this fails because I get different patterns in IE, sometimes a ·\n, sometimes a \n···. In a Python, parse the new HTML, extract the new text/content, insert it into the old HTML so the elements and format never change, just the content. This is very difficult and seems to be overkill.

• Extension objects pattern

  - by voroninp

  In this MSDN Magazine article Peter Vogel describes Extension Objects partten. What is not clear is whether extensions can be later implemented by client code residing in a separate assembly. And if so how in this case can extension get acces to private members of the objet being extended? I quite often need to set different access levels for different classes. Sometimes I really need that descendants does not have access to the mebmer but separate class does. (good old friend classes) Now I solve this in C# by exposing callback properties in interface of the external class and setting them with private methods. This also alows to adjust access: read only or read|write depending on the desired interface. class Parent { private int foo; public void AcceptExternal(IFoo external) { external.GetFooCallback = () => this.foo; } } interface IFoo { Func<int> GetFooCallback {get;set;} } Other way is to explicitly implement particular interface. But I suspect more aspproaches exist.

• Do you sign contracts digitally or still on paper? And what do clients think?

  - by user1162541

  We are all getting used to checking a box and putting our name in a text field to create a contract with an airline, a hosting company, or a software download. However, for some reason I am still asking clients to sign our contracts for website development on paper, and send me a scan. Few complain about this procedure, but I am personally thinking: what am I doing, doing this the old fashion way?! Signing contracts digitally would be faster, more convenient for clients and for me, and easier to store. So to me it appears to be time to start creating some contract agreement online that clients can read, then print their name, and mark a box "I AGREE WITH THIS CONTRACT AND BY PRINTING MY NAME I AGREE TO SIGNING THIS", or something like that. I would record their IP, browser data, and time of signing. If I really want to ensure their identity, I could link this to OpenID and require them to log in with their e-mail so that I can ensure that they are logged in on an existing e-mail account. Sounds OK to me. My question is: is this practice becoming a standard practice in professional IT services? Are you (as a professional) doing this? If you are, how do clients react? Any drawbacks doing this? EDIT: This question is not about the legal aspects. It is about common practices among programmers and web-development companies, and what clients think of this.

• How do i impress employers with my resume?

  - by acidzombie24

  I built a entire website from scratch in 10days which looks and feels professional with the site being unique. The site has features like logging in, sending activation emails, tag/content search (lucence.net), syntax highlighting (prettify) and a diff (one of the js diffs), markup for comments all on this site and autocomplete in a textbox (remember, 10days). I wrote i have 5+ years of C# experience (i could lie and say more but smart employers will know its only 8 years old and 1.1 is very different from what we use now). I had employers REPEATEDLY say they are looking for someone who has more C# experience... wtf. Maybe they don't read my CV, maybe they dont believe it or ignore me because i am not yet a graduate. I laughed when i first read Steve Yegge The Five Essential Phone Screen Questions as i knew all of that (although i still never used graph datastruct nor know much about it). I'm pretty sure competency wise i can do the job. I am also positive no one noticed i have markup, a diff, autocomplete nor email activation/forget password (i offer a test user account). So maybe my site/example work isnt impressive bc you dont realize what is in it. In short i dont think they read my CV or notice my site. How do i impress employers? PS: The problem is i dont get to the interview. I had one and ruined it by speaking too technical to the PM because i was nervous. The other 25+ jobs either didnt contact me or was kind enough to send a rejection email.

• Design practice for securing data inside Azure SQL

  - by Sid

  Update: I'm looking for a specific design practice as we try to build-our-own database encryption. Azure SQL doesn't support many of the encryption features found in SQL Server (Table and Column encryption). We need to store some sensitive information that needs to be encrypted and we've rolled our own using AesCryptoServiceProvider to encrypt/decrypt data to/from the database. This solves the immediate issue (no cleartext in db) but poses other problems like Key rotation (we have to roll our own code for this, walking through the db converting old cipher text into new cipher text) metadata mapping of which tables and which columns are encrypted. This is simple when it's just couple of columns (send an email to all devs/document) but that quickly gets out of hand ... So, what is the best practice for doing application level encryption into a database that doesn't support encryption? In particular, what is a good design to solve the above two bullet points? If you had specific schema additions would love it if you could give details ("Have a NVARCHAR(max) column to store the cipher metadata as JSON" or a SQL script/commands). If someone would like to recommend a library, I'd be happy to stay away from "DIY" too. Before going too deep - I assume there isn't any way I can add encryption support to Azure by creating a stored procedure, right?

• Should one use a separate database for application data and user data?

  - by trycatch

  I’ve been working on a project for a little while and I’m unsure which is the better architecture. I’m interested in the consensus. The answer to me seems fairly obvious but something about it is digging at me and I can't pick out what. The TL;DR is: how do you handle a program with application data and user data in the same DB which needs to be able to receive updates to the application data periodically? One database for user data and one for application, or both in one? The detailed version is.. if an application has a database which needs to maintain application data AND user data, and the user data all references application data, it feels more natural to me to store them in the same database. But if there exists a need to be able to update the application data within this database periodically, should this be stripped into two databases so that one can simply download the updated application data database file as an update and replace the old one? Or should they remain as one database, and the application data be updated via a script which inserts the new data into the existing database? The second sounds clearly preferable to me... but for some reason just doesn’t feel right, and I can't pick out quite why.

• Network printer problem with 12.04

  - by G. He

  I had an HP LaserJet 3030 printer connected to an Ubuntu box. It worked fine with 11.10. I was able to print from Ubuntu as well as from Windows and Mac from the home network. About a month or so ago, I upgraded 11.10 to 12.04, then things started to falling apart. My Windows 7 laptop couldn't print to the printer any more. Today, I installed many updates on 12.04, hoping that would fix the printing problem. Unfortunately, it made the situation much worse. Now not only my Windows 7 laptop won't print, my XP desktop won't print either. Every time I print something from the Windows computer, the Ubuntu box logs an error message in /var/log/samba/log.'machineName' as: _spoolss_OpenPrinterEx: Cannot open a printer handle for printer \\server. It is interesting that it uses the server name as the printer, not the \\server\xyzprinter as the printer name. Anyone had a similar problem? Anyway to work around the problem?

• 12.04 Taking forever for no apparent reason

  - by Sam

  First off, I'd just like to say how much I'm loving Ubuntu so far. It's one of my first steps into Linux, but so far it's blown away Windows in almost every regard. Now, onto my problem. My brothers have some old Dell Dimensions that are barely clinging to life. They were both running XP Home Premium. The 2400 installed just fine, no issues at all. Now, the other computer, the 3000 isn't clearing the screen with the Ubuntu logo and the pulsing dots. I've tried multiple discs, including the exact same one that gave me no issue in the other computer, and I'm at a loss. Does anyone have any suggestions as to where the problem might lay? They're both 32 bit Intel processors, and it's the correct version of Ubuntu. Is it a bad disc drive? Hardware incompatibility? Thanks for any assistance that can be provided.

• Problems with LibreOffice Impress?

  - by kkp

  I am a big fan of Ubuntu. I have recently switched from Latex to LibreOffice Impress for PPT because it seems that with Impress you can quickly create slides. I am using LibreOffice 3.4.4 OOO340m1 (Build:402) on Ubuntu 11.04. I am saving them as .ppt format. However, facing the following problems. It is really frustrating and forcing me to use Windows/MAC just for making slides. Font is changing from Arial to TimesNewRoman specifically for Tables when I reopen an Impress presentation. Tables are stretched if I reopen an Impress presentation. Impress is not allowing me to compress them (the stretched tables) and I have needed to make a fresh table. Several other modifications are reverting back when I reopen an Impress presentation. For example, the "transparency" change to the borders (e.g., for rectangular shape). Arbitrarily Impress is crashing. It would be great if someone help me to resolve these issues. Thanks.
