• LINQ Style preference

  - by Erin

  I have come to use LINQ in my every day programming a lot. In fact, I rarely, if ever, use an explicit loop. I have, however, found that I don't use the SQL like syntax anymore. I just use the extension functions. So rather then saying: from x in y select datatransform where filter I use: x.Where(c => filter).Select(c => datatransform) Which style of LINQ do you prefer and what are others on your team are comfortable with?

• How to Back Up Your Linux System With Back In Time

  - by Chris Hoffman

  Ubuntu includes Déjà Dup, an integrated backup tool, but some people prefer Back In Time instead. Back In Time has several advantages over Déjà Dup, including a less-opaque backup format, integrated backup file browser, and more configurability. Déjà Dup still has a few advantages, notably its optional encryption and simpler interface, but Back In Time gives Déjà Dup a run for its money.

• Why are part-time jobs in programming an anomality?

  - by Mikle

  I've recently quit my full time developing job at mega-corp, and I decided that I'll look for a part time job. Since then I've talked to half a dozen potential employers, and every one of them had the same reaction when I said the magic words "part-time" - they all closed up and became suspicious. Now, I understand that it might just be me, so as control I asked every one of them what if I were willing to work full time, and they all said I would probably get an offer. My question is two fold: Why, as an employer, would you give up a competent, even great, developer, simply because he wants to work 3 days a week and not 5? How do I sell the story of part time job better? I usually just list my reasons which are that I prefer that balance currently in my life and that I want to work on my own projects, but it leaves them even more suspicious - am I going to start something myself and quit? Am I just lazy?

• SQL SERVER – Puzzle – SELECT * vs SELECT COUNT(*)

  - by pinaldave

  Earlier this weekend I have presented at Bangalore User Group on the subject of SQL Server Tips and Tricks. During the presentation I have asked a question to attendees. It was very interesting to see that I have received various different answer to my question. Here is the same question for you and I would like to see what your answer to this question. Question: SELECT * gives error when executed alone but SELECT COUNT(*) does not. Why? Select * - resulting Error Select count * - NOT resulting Error Please leave your answer as comment over here. If you prefer you can blog post about this on your blog and put a link here. I will publish valid answer with due credit in future blog posts.

• Authentication for users on a Single Page App?

  - by John H

  I have developed a single page app prototype that is using Backbone on the front end and going to consume from a thin RESTful API on the server for it's data. Coming from heavy server side application development (php and python), I have really enjoyed the new different design approach with a thick client side MVC but am confused on how best to restrict the app to authenticated users who log in. I prefer to have the app itself behind a login and would also like to implement other types of logins eventually (openid, fb connect, etc) in addition to the site's native login. I am unclear how this is done and have been searching - but unsuccessful in finding information that made it clear to me. In the big picture, what is the current best practice for registering users and requiring them to login to use your single page app? Once a user is logged in, how are the api requests authenticated? Can I store a session but how do I detect for this session in the API calls? Any answers to this would be much appreciated!

• How to take a screenshot every n second?

  - by Seppo Erviälä

  What software can I use to take screenshots with a set interval? I'd like to take screenshots every 2 second or so. Command-line and GUI are both ok. I'd prefer software that can also resize and compress each screenshot. EDIT: What I realized I really wanted to do was take a screenshot and a picture with webcam at the same time. I ended up doing some python: import threading import os def capture(i): i += 1 threading.Timer(2.0, printit, [i]).start() fill = str(i).zfill(5) os.system("scrot scrot-%s.jpg" % fill) os.system("streamer -o streamer-%s.jpeg -s 320x240 -j 100" % fill) capture(0)

• Is BDD actually writable by non-programmers?

  - by MattiSG

  Behavior-Driven Development with its emblematic “Given-When-Then” scenarios syntax has lately been quite hyped for its possible uses as a boundary object for software functionality assessment. I definitely agree that Gherkin, or whichever feature definition script you prefer, is a business-readable DSL, and already provides value as such. However, I disagree that it is writable by non-programmers (as does Martin Fowler). Does anyone have accounts of scenarios being written by non-programmers, then instrumented by developers? If there is indeed a consensus on the lack of writability, then would you see a problem with a tool that, instead of starting with the scenarios and instrumenting them, would generate business-readable scenarios from the actual tests?

• PostgreSQL data diff

  - by skanatek

  Note: this question is not about syncing database schema/structure Problem In my web application I have a PostgreSQL database server (PGS) and a (separate machine) business logic server (BLS) which regularly (every minute or two) queries 'SELECT ALL' against PGS. The problem is that the 'SELECT ALL' query can easily return 50-200 MB each time. It is obvious that it would be not so good architecture-wise to transfer so much data so frequently over the web. Possible solution What I would like to do is to run some diff tool on PGS and compare the new query with the previous query (all this should be done on PGS). Once the comparison is done I would like to get a dump from PGS and transfer it to BLS. I expect that a diff-based dump would be much, much smaller than the whole 'SELECT ALL' query. Question Is there any data diff tool for PostgreSQL that can do diffs that compare PostgreSQL data between 2 tables or 2 dumps? Note: I would prefer some open-source software tool.

• How can I mount an AFS filesystem?

  - by Ben

  My current method is to mount the filesystem via SSH using Nautilus's graphical interface, but I would much prefer to be able to use some tool that mounts the AFS filesystem and gives me access to AFS-specific features (permissions, etc.). I've tried installing OpenAFS via apt-get, but so far the kernel module has refused to compile. Also, assuming I get OpenAFS installed, I'm not quite sure how to actually mount the remote filesystem to, say, /media/afs or some directory. I'm running Maverick with the 2.6.36-020636-generic kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/ Thanks for the help!

• Conditions for a traditional friends system vs. open following system

  - by Dan

  I'm just curious for everyone who is developing social sites out there. When you build a method for connecting users, do you prefer to use a following-style system (follow me, you can see all of my information and I can just choose to follow you back), or instead do you choose to have a friends-style system (I have to allow you see all of my information on your homepage, even if it is open to the public, vise versa). Why and under what circumstances do you use each? How do you manage privacy between your users? Have you use another way to connect your users? Examples of what methods you've choose and how you manage the user's privacy (private by default vs open to the web) are awesome; it could show correlation and provides an actual look.

• Is your IP address neighborhood important for SEO?

  - by Evgeny

  Can other websites on your shared host affect the rank of your website in the Google index? (same IP address as yours, potentially malicious/low-trust content) Can other websites on your IP class affect the rank of your website in the Google index? (different actual IP, malicious/low-trust content) Clarification: Domain class, is what you get when you run a whois query on an IP address. Example: NetRange: 69.163.128.0 - 69.163.255.255 CIDR: 69.163.128.0/17 PS: Prefer answers with experience or links to trustworthy material, over speculations, assumptions and gut feelings.

• Publish/Subscribe/Request for exchange of big, complex, and confidential data?

  - by Morten

  I am working on a project where a website needs to exchange complex and confidential (and thus encrypted) data with other systems. The data includes personal information, technical drawings, public documents etc. We would prefer to avoid the Request-Reply pattern to the dependent systems (and there are a LOT of them), as that would create an awful lot of empty traffic. On the other hand, I am not sure that a pure Publisher/Subscriber pattern would be apropriate -- mainly because of the complex and bulky nature of the data to be exchanged. For that reason we have discussed the possibility of a "publish/subscribe/request" solution. The Publish/Subscribe part would be to publish a message to the dependent systems, that something is ready for pickup. The actual content is then picked up by old-school Request-Reply action. How does this sound to you?? Regards, Morten

• Good library for search text tokenization

  - by Chris Dutrow

  Looking to tokenize some text in the same or similar way in which a search engine would do it. The reason we are doing this is so that we can run some statistical analysis on the tokens. The language we are using is python, so would prefer a library in that language, but could probably set something up to use another language if necessary. Example Original token: We have some great burritos! More simplified: (remove plurals and punctuation) We have some great burrito Even more simplified: (remove superfluous words) great burrito Best: (recognize positive and negative meaning): burrito -positive-

• Going back to ASP.Net Webforms from ASP.Net MVC. Recommend patterns/architectures?

  - by jlnorsworthy

  To many of you this will sound like a ridiculous question, but I am asking because I have little to no experience with ASP.Net Webforms - I went straight to ASP.Net MVC. I am now working on a project where we are limited to .Net 2.0 and Visual Studio 2005. I liked the clean separation of concerns when working with ASP.Net MVC, and am looking for something to make webforms less unbearable. Are there any recommended patterns or practices for people who prefer asp.net MVC, but are stuck on .net 2.0 and visual studio 2005?

• Is big (as much as big) size display (Monitor) always better for Development?

  - by Jitendra Vyas

  Is bigger size display ( Monitor) always better for Development? I'm going to buy a new LCD Monitor. I mostly work in Adobe Photoshop, HTML, CSS, jQuery and Wordpress. Budget is not a problem. Many options are there for LCD Monitor SIZE My questions are Would it better for maximum size, or large size monitor are not good always? Would it better to buy 21.5 inch x 2 than one 30 inch monitor? Which monitor size would you would prefer between the size of 21.5 inch - 30 inch, if bugdet is not a problem?

• Using multiple indexes with buffer objects in OpenTK

  - by Rushyo

  I've got multiple buffers in OpenGL holding data on position, normals and texcoords. I also have an equal number of buffers holding distinct index data for each of those buffers. I quite like this format (indvidual indexes for each buffer) utilised by COLLADA since it strikes me as optimally efficient at accessing each buffer. I've set up pointers to the relevant data arrays using VertexPointer, NormalPointer, etc however I have no way to assign pointers to the index buffers since DrawElements appear to only look at one ElementArrayBuffer. Can I utilise multiple indices some way or will I be better off using a different technique which can support this? I'd prefer to keep the distinct indices if at all possible.

• How do I take an image/backup of Ubuntu partition and restore to VirtualBox VM

  - by whizkid

  I have Ubuntu 10.04 installed on an older hard disk. I recently bought a new disk and already installed Windows 7. I dont want to use the older disk anymore, and I would like to keep on using Ubuntu in a virtual machine on the new disk(to avoid the possible mess-ups of dual boot and I found VirtualBox is the best free tool for this). I wish to keep the exact same data\programs\configurations\settings I had been using in Ubuntu for so long, and avoid the tedious part of having to reconfigure so many things. How do I backup\restore Ubuntu to another disk? I would prefer a free tool to do the backup\restore.

• Installing windows after ubuntu is installed (need to create ntfs partition too)

  - by Brent Roose

  I prefer Ubuntu to work on, but for some applications for school, I need windows. I've done some research and have a few problems: I only have one hard drive which is formatted as ext4, not ntfs. Many people say I have to use Gparted to create an ntfs partition to install windows on, the only problem is that I need to unmount my drive to do this, which isn't possible I think because I only have one. I thought about mounting my HDD as a slave on a windows laptop but I don't manage to partition it with windows partition manager, so I think I need some kind of tool. which one? next problem I'll probably have is that I won't be able to boot ubuntu after installing windows because grub will be removed from my MBR. are there any good guides around here? I've used some kind of tool before, but it crashed my whole HDD so I had to fully format it.

• What good Social Networking Site solutions there are? [closed]

  - by ZetsubouWebmaster

  What good and free Social Networking Site solutions there are? I tried many options but most of them are either too complicated, too simple, or just do not work... I tried: Dolphin, DZOIC-Handshakes, elgg, Oxwall, SocialEngine, and some plugins for wp and other CMS. I don't need much, just: groups, chats, forums, profiles, PM, photos, pages, comments, search, statistics. Most of which included in pretty much every CMS out there, but not all.. So, what good solutions there are? Also I don't mind paying some money (I guess no more then $200), but I'd prefer if it was a free open source engine. Of course it should be PHP+MySQL based.

• host and share files in my hosting

  - by user1314836

  I currently have a domain+hosting with unlimited hosting space for our website. On the other hand, I use Dropbox to share our organizational files and photos between about 10 users. The thing is that sharing photos uses too much space for what a free Dropbox account offers. So I am thinking of taking advantage of my hosting space, but using FTP seems not to be ideal for users who are not too skilled with computers. In addition, it doesn't handle versions in case some user makes a mess of it. And using a public FTP to upload and giving them only download permission doesn't seem a good idea as I am only the CTO. So what I want is basically to implement a local Dropbox for a few users, but I'd prefer something that is not too complex to install/mantain. Thank you a lot.

• Bare-metal mode for Ubuntu

  - by user1071136

  I'm interested to benchmark a console-mode application, and would like to reduce to a minimum any interferences from other processes in the system. Is there an easy way to boot into Ubuntu 12.04 in a "bare-metal" mode ? I'm still interested in casually booting a "desktop" version of Ubuntu (so will prefer to avoid permanent changes), and would like to avoid installing a separate Ubuntu-server version. My use-case is the following - Application is single-thread and console-mode only. Test-box has 12GB of memory. I ssh into the test-box. Seems I can skip at least Unity, X-server and their dependents.

• Why is filesystem preferred for logs instead of RDBMS?

  - by Yasir

  Question should be clear from its title. For example Apache saves its access and error logs in files instead of RDBMS no matter on how large or small scale it is being utilized. For RDMS we just have to write SQL queries and it will do the work while for files we must decide a particular format and then write regex or may be parsers to manipulate them. And those might even fail in particular circumstances if great care was not paid. Yet everyone seems to prefer filesystem for maintaining the logs. I am not biased against any of these methods but I would like to know why it is practiced like this. Is it speed or maintainability or something else?

• Maximized Office 2007 gets cut off on multi-monitor setup with different resolutions

  - by Adam M-W

  I've got an external monitor plugged into my laptop that I like to use for typing up documents, but I've noticed that when Word is maximized it gets cut off at where the primary monitor's bounds are. Is this a bug in Wine (i'm using version 1.3.32), or with my Window Manager (metacity with compositing enabled, version 2.34.1), with my graphics drivers (nouveau) or something else? I know that I can fix it by unmaximizing (it doesn't get cut off and I can resize to the entirety of the second monitor), but it keeps on maximizing itself as it (rightly so) knows that it should be taking up the entire screen. I don't really want to use the "Emulate a virtual desktop feature", I would prefer to find the source of this issue.

• How to Change the Window Border Size in Windows 8

  - by Chris Hoffman

  The window borders on Windows 8’s desktop are fairly thick by default, but they don’t have to be – you can customize the side of the window borders with an easy-to-use application or a quick registry tweak. You can shrink the window borders and make them fairly thin, just as they were on previous versions of Windows. Or you can increase the window border size and make them extremely thick, if you prefer.. HTG Explains: Does Your Android Phone Need an Antivirus?
