• 5 Ways To Quickly Launch Programs On Windows

  - by Chris Hoffman

  Do you still launch programs on Windows by hunting down a desktop shortcut and double-clicking it? There are better ways – Windows has several built-in tricks for quickly launching applications. Even if you know all the built-in tricks, you may want to try out Launchy or another third-party launcher – some people swear by them. They offer more features than the Start menu search built into Windows. HTG Explains: Is ReadyBoost Worth Using?

• Perspective in Modeling

  - by drsql

  Your task, model a database that represents a suburban block.  You survey the area, and see the following houses (pictures culled from Wikipedia here ) and So you look at the houses, start modeling roofs, windows, lawn, driveway, mail boxes, porches, etc etc. You get done, and with your 30+ tables you are feeling great, right? I know I would be. “I knocked this out of the park! We can capture everything about these houses.  I…am…a…superhero database modeler,” I think, “I will get a big...(read more)

• What failure can kill a long running IRC client? [closed]

  - by Xeoncross

  I have an IRC bot that I built in PHP using sockets that attempts to run forever and (if disconnected) reconnects again. I have it listening to several channels. Apparently it's fairly resilient, because it can run for several days before the process ends and CRON has to start it up again. However, based on the fact the process ends I'm assuming there are other conditions I'm not accounting for that are causing problems. I have nothing in my error logs giving me a hint. In addition, sometimes the process will continue running - but I notice it's no longer present in any of the channels on the IRC server which makes me think it violated some part of the protocol. I have logic setup to handle: reply to PING's correctly reconnect on disconnect (and reconnect to channels) respond to private messages (so someone doesn't ban it) prevent memory leaks What other failure could be killing my long-running IRC client?

• What Language is unity written in?

  - by John

  What Language is Unity written in? Also, where can i get its source code? I have an idea for a windowing enviroment or shell (dont know what to call it). What i want to do is teach myself to create it. i like some of several ideas i have seen, but i want to redo all of them, also the concept of how a desktop works. I figured learning the language Unity is written in, and studying Unity and Gnomes code would be a good start. i am on Ubuntu 12.04 acer aspire 5920 3 gb ram 160 gb hard drive

• Is acoustic fingerprinting too broad for one audio file only?

  - by IBG

  We were looking for some topics related to audio analysis and found acoustic fingerprinting. As it is, it seems like the most famous application for it is for identification of music. Enter our manager, who requested us to research and possible find an algorithm or existing code that we can use for this very simple approach (like it's easy, source codes don't show up like mushrooms): Always-on app for listening Compare the audio patterns to a single audio file (assume sound is a simple beep) If beep is detected, send notification to server With a flow this simple, do you think acoustic fingerprinting is a broad approach to use? Should we stop and take another approach? Where to best start? We haven't started anything yet (on the development side) on this regard, so I want to get other opinion if this is pursuit is worth it or moot.

• Installed 7zip. Not working. And when removing, it says to remove Fileroller as well

  - by rainlover

  I installed 7zip today from software centre but it won't showed up in launch bar (side bar). I did a lot but failed to open 7zip "window" from any where. I clicked it in dash but then I was sent to software center showing that it is installed. I just don't know how to start it. Nor it is showing in right-click menu. I actually wanted to open flareget which is in .tar.gz. Ubuntu's default archive opener isn't opening it and showing me this: And if I try to remove 7zip, it's saying file-roller should also be removed: What's going on and what's solution?

• How to organize unit/integration test in BDD

  - by whatf

  So finally after reading a lot, I have understood that the difference between BDD and TDD is between T & B. But coming from basic TDD background, what I used to was, first write unittest for database models write test for views (at this point start with integration test as well, along with unittests) write more integration tests for testing UI stuff. What would be a correct way to approach BDD. Say I have a simple blog application. Given : When a user logs in. He should be shown list of all his posts. But for this, I need a model with a row user, another row blog posts. So how do we go about writing tests? when do we create fixtures? When do we write integration (selenium) tests?

• Battery Power when running Ubuntu 14.04 LTS in dual boot

  - by Amro A.

  This is only a general question in order for me to get a better idea of my dual boot (windows 8 & Ubuntu) systems. I noticed that every time I run Ubuntu (which is becoming more often) the battery power gets consumed really fast. I am not performing any special tasks at the moment, just getting to know the system, for example, sound settings, watching videos, surfing the net and so on. When I do the same thing in Windows 8 the battery lives a considerable amount of time longer. Is this something to do with Ubuntu or is it because of the dual boot that I have going on? In other words, if I start running Ubuntu all by itself on my laptop, will it be more power consuming than Windows 8?

• X crash at login for 1 user

  - by marxjohnson

  User switching wasn't working on my 12.04 LTS desktop (just dropped me to TTY8 with a blinking cursor) so I tried to manually start a second X session by logging in to TTY6 and running startx -- :1. This didn't work either, and my machine locked up. Now when I try to log in as the second user from LightDM, X instantly crashes and I'm thrown back to the login screen. Other accounts on the machine work fine, and it happens for every desktop environment. I've had a poke around in my home directory, but I can't see anything obvious to change/delete to get it working again. Can anyone advise please?

• Use open-source programs in your company?

  - by eversor

  Is there any cons of making your employees use open-source programs in your company? I am planning to start a bussiness and I wonder why companies usually work with proprietary software, as Microsoft Word to quote the most famous one. Why do not they use Open Office (or Libre Office) etc.? From my point of view, you can save a lot of money and help the open-source community by, for instance, giving them part of your benefits in form of donations. I do not know any (medium-big) company that does this. Probably you could give me some examples, just to prove that this model of open-source usage/collaboration works rocks.

• Can it be useful to build an application starting with the GUI?

  - by Grant Palin

  The trend in application design and development seems to be starting with the "guts": the domain, then data access, then infrastructure, etc. The GUI seems to usually come later in the process. I wonder if it could ever be useful to build the GUI first... My rationale is that by building at least a prototype GUI, you gain a better idea of what needs to happen behind the scenes, and so are in a better position to start work on the domain and supporting code. I can see an issue with this practice in that if the supporting code is not yet written, there won't be much for the GUI layer to actually do. Perhaps building mock objects or throwaway classes (somewhat like is done in unit testing) would provide just enough of a foundation to build the GUI on initially. Might this be a feasible idea for a real project? Maybe we could add GDD (GUI Driven Development) to the acronym stable...

• FGLRX Drivers Keep Crashing | "Installation Media" reads Natty even though I'm in Precise

  - by Tom Thorogood

  I recently switched back to Ubuntu after a year or so of hardly touching my Ubuntu partition, and upgraded from Natty. Every time I start up, i get the "A problem has occurred..." popup, but it won't let me report it because Precise is not in beta. The details on the report show a segfault, and going through all the details, I notice that it lists Natty under "InstallationMedia" -- I just installed these drivers, so I'm really unsure why it's saying this. I wish I could copy this entire error report, but I see no way of doing that (is it stored somewhere in /var/log?). I'm new to the Unity interface (it's why I stopped using Ubuntu to begin with, but now that I'm getting used to it I'm liking it better). Thanks.

• How relevant is PHP today for browser games?

  - by Bitgarden

  I was the lead developer of 2 moderately successful browser games quite a few years back, and plan on working on a new game soon. At the time, I wrote them in pure PHP (no template engine or anything of the sort). I'd like to start working on a new game, but have been out of the web development world for a while. Reading around, I hear a lot of good about Rails, Django, Node.js, etc., with which I have no experience (although I know my way around Python, Javascript, and the others quite well). So my question is the following- if I were to go in my old ways and go with PHP again, would I be making things hard for myself? Would picking something more "trendy" have a real impact on my development? In addition, does anyone have any pointers relating to specifically developing browser games with these more modern tools?

• Retail Link data storage requirements

  - by Randy Walker

  I was asked today about how much data an average Retail Link analyst (Walmart vendor) would consume.  I thought I would write this small post for future reference. Of course this vastly depends on the amount of skus, how long you want to archive data, and if you want store level sales. Most reports take up very little space. Most times when you download a report (total sales per sku for last week), you will overwrite the previous week’s report.  However, most users will take the data inside their downloaded report, and add it to a database or larger excel spreadsheet.  This way, the user has a history of the sales of each item/sku per week over the last 2+ years.  I would estimate 1 user to consume around 1-2 gb of space, at most, over the course of 2 years. If you start archiving store level sales those numbers can drastically increase up to 10gb or more very quickly.

• Wired : "Japanese despise western games" - how much is it true?

  - by user712092

  Wired has article that western games are seen as "bad games". Why is that? If that is true, than what do they see as bad? This article, i think, is biased towards western games: “The other day,” says Q Entertainment’s Mielke, “I was having lunch with a friend and I said, ‘Have you ever played StarCraft?’ And he said, ‘What’s StarCraft?’ Sometimes it’s just really shocking that their gaming vocabulary isn’t as extensive as it could be. I think Japanese game developers need to start playing other people’s games to open their minds, just like a writer might want to read classic literature to be inspired.” Rather than trusting such articles, I rather ask here.

• Chrome keeps crashing after updates

  - by Phil

  I'm a chrome user and an enthusiast but few days ago I made Ubuntu get some updates using Update Manager, then I turned off my notebook and when I restarted it, I tried to start Chrome which after a few seconds turned the screen completely black, and some errors appeared for few seconds and then I got logged off, and had to re-login, and when I opened Chrome again the same thing happened! I've uninstalled it with Synaptic and did complete cleanings before re-installing Chrome but nothing succeeded. Now I can't use either Chromium and Chrome, but Firefox works. It's a very strange thing, never happened to me before and I don't know what to do because I had all my bookmarks syncronized in Chrome! Please help if you can :)

• How to support tableless columns with WYSIWYG editor?

  - by Andy

  On the front page of a site I'm working on there's a small slideshow. It's not for pictures in particular, any content can go in, and I'm currently setting up the editing interface for the client. I'd like to be able to have one/two/more columns in the editable area, and ideally that would be via CSS - does anyone know of a WYSIWYG editor that supports this? I'm using Drupal (would prefer not to involve Panels as it would require a bit of work to make it a streamlined workflow for content entry) in case that matters to anyone. To start the ball rolling, one way would be to use templates. I know CKEditor supports templates, and it looks like TinyMCE might have something similar. I don't know how well these work with tableless columns (the CKEditor homepage demo uses tables to achieve its two column effect). Holding out for a cool solution!

• Processing a list of atomic operations, allowing for interruptions

  - by JDB

  I'm looking for a design pattern that addresses the following situation: There exists a list of tasks that must be processed. Tasks may be added at any time. Each task is wholly independent from all other tasks. The order in which tasks are processed has no effect on the overall system or on the tasks themselves. Every task must be processed once and only once. The "main" process which launches the task processors may start and stop without warning. When stopped, the "main" process loses all in-memory data. Obviously this is going to involve some state, but are there any design patterns which discuss where and how to maintain that state? Are there any relevant anti-patterns? Named patterns are especially helpful so that we can discuss this topic with other organizations without having to describe the entire problem domain.

• Web hosting announced downtime and how it affects FORWARD domain names?

  - by maple_shaft

  Our web hosting provider that holds our FORWARD domain names announced that at some point in the next couple weeks they will be migrating servers and that this will cause a 5-10 minute downtime at some point in that week during what happens to be our core business hours. They cite for technical reasons it is impossible to give an exact date or time when this downtime will occur. My questions are: If my domains are set to FORWARD to a static IP on servers not hosted by the web hosting provider in question then will this affect the DNS servers correctly routing to my website? Are their legitimate technical reasons for such a wide window of time, or could this just be a blanket statement to cover laziness in not being more organized with their server migrations? Are such downtimes normal for web hosting providers, or should I start to consider other providers?

• How to use unused space in ubuntu

  I installed ubuntu on my machine with only 80 GB of memory anticipating that I will remove it later but now I want to keep it forever (until I am frustrated with linux).

• Tons of problems a new user is encountering

  - by Barney

  I've borrowed this laptop from a friend. I wanted to install AdBlock to boost performance. First weird thing was that even though I was on Chrome, Chrome suggested me installing him? So I tried to install ,than it gave me some message about broken dependencies. I Googled and tried to run those commands you guys were suggesting, but than it popped up error messages about everything again. Than I found out that some package called linux image generic is broken, than I tried to find an answer to that, but on the topic it was ” ndk.bhj\spo;ujvsdljvaEOYUFgidgAPIF;hsgvk in other words, I didn't understand anything about it, than there's this thing: E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? Seriously, when I'm trying to fix an error, there is another one. I'm on something called GNOME. Sooo, where do I start?

• How do you format arrays within parameters?

  - by joslinm

  I'm talking about something like this: echo $form->input('general_addresss', array( 'label' => 'Where will you go today?' 'format' => array('before', 'input', 'after', 'label', 'after', 'error') )); Do you start with one array parameter, then break a line? If it can't fit on a line, do you immediately break a line? After of which, do you do a set number of tabs over? What happens if an array within an array has lots of properties? Is there any particular guide you follow?
