• Wireless speed drops over time and doesn't get up if not reconnected

  - by Vili Lehto

  I am using Ubuntu 12.10 64bit and I have a Asus PCE-N15 wireless card(in PCI-E slot). The problem is that first when I connect to my WiFi network the speed is just fine, and actually my link speed never drops, it shows a solid 150mb/s+ link speed and good signal. But the download and upload speeds drop dramatically after couple minutes of use and I have to reconnect to fix this. Network is type IEEE 802.11bgn and uses WPA2/AES encryption. I don't have similar problems on the windows side, and the network is working fine on every other device. iwconfig shows this: wlan0 IEEE 802.11bgn ESSID:"WLAN-AP" Mode:Managed Frequency:2.412 GHz Access Point: 00:1E:AB:05:EF:31 Bit Rate=300 Mb/s Tx-Power=20 dBm Retry long limit:7 RTS thr=2347 B Fragment thr:off Encryption key:off Power Management:off Link Quality=61/70 Signal level=-49 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:2 Missed beacon:0 So the question is: Is there a way to fix this? Thanks in advance.

• What are some good resources for learning about file systems? [closed]

  - by Daniel

  I'd like to learn about file system design at a very detailed level. I'm currently in a graduate level operating systems course, and we're currently going over file systems. We mostly discuss papers and such, but our semester long project is to implement a log-structured file system using fuse and a virtual disk. Are there any good books that focus heavily on file system design and implementation? I have some conceptual clouding on things that seem very basic such as "when we say that an inode has pointers to blocks, do we mean anything besides the inode keeping track of block numbers? Is there any other format for 'disk pointers'?" I'm actually looking at file system design to start my career, so I'm probably going to try to implement a more traditional file system with fuse and our virtual disk format after this course is over.

• Having MSc or Bsc with Experience, whats worth in industrial environments?

  - by Abimaran

  I'm a fresh graduate in Electronic & Telecommunication field, and in our University, we can have major and minor fields in the relevant subjects. So, I majored in telecommunication and minored in Software Engineering. As I learned programing long before, Now I'm passionate in SE and programming. And, I want drive into the SE field. And, It came to know that, in industries, most of them expecting the candidates to have the Bsc + experience of two+ years, or having a MSc in the related field. [I'm referring my surrounding environment, not all the industries]. My Question, How do they consider those MSc and BSc + experience guys in the industries? IMO, having MSc is great assert with comparing to have experience. Because, in the industry, you can drive in a particular technology (Java, .Net or some thing else), not all, and with MSc, we can get the domain knowledge, not a particular technology! Thanks!

• How to "back track"?

  - by esqew

  I find that I start projects and, due to my lack of experience, find that old database structures and huge blocks of code are inefficient and memory-costly. However, by the time I realize a re-design of the entire project is needed, the project has grown to such a size that it is simply too late to go back and modify the project in its current state and requires a completely new project file and the whole shebang. How should I prevent ruts such as this one, where it is too late to go back and modify the current project to fit specifications modified far down the road from the creation of the project? (Apologies in advance for confusing grammar, it's been a long day here... as you can probably tell.)

• What's new with Java technology? Java Embedded

  - by hinkmond

  As this article points out, Java Embedded is a safer, more robust and easier to develop platform for small networked devices. So, get ready for good things to come from Java Embedded... See: Java Embedded: Next New Thing Here's a quote: Through the past few years the industry as we know it has seen a big boom with the mobile and cloud revolution. Today, there has been an enormous amount of buzz around machine to machine (M2M) or the "Internet of Things," since we are moving into a state where everything is going to have to be interconnected and will have to properly communicate together... Today, Java Embedded provides that platform. I like it! As long as there's no Zombie Apocalypse, I think Java Embedded has a great future! Hinkmond

• Notebook overheating

  - by user71372

  I'm asking this question because I've tried many tips to solve they don't work and it sounds like a non-fixed bug ubuntu. My problem is with overheating. I've recently installed Ubuntu Precise 12.04 LTS alongside with MS Windows 7 on my notebook Samsung 530U. I'm using both via dual-boot mode. I've no heating problem with MS Win 7 and the fan speed is normal even with long run utilization. However, when booting with Ubuntu and after short time, the PC got very hot and the fan was running at max speed. I installed a tool called Jupiter, I put it in "Power Saving" mode but no result. Now, I avoid using ubuntu because I fear it'll damage my all new notebook. Please can you give me a "FINAL" fix of this problem (lot of answers exist but I don't know the more accurate and efficient one). Thank you in advance.

• Pros and cons of the Google font API

  - by Seamus

  I am currently using a font from the google font directory on my website. I don't fully understand how it works, but it seems like when someone opens my site, their browser is told to go and fetch the font from Google. (correct me if I'm wrong). Now, what I'm wondering is, what are the pros and cons of this over just specifying a font family the old-school way? Presumably doing it the google font directory way has the advantage that they'll definitely see the font I want them to. (as long as the font directory is up). But does this way have disadvantages? Maybe using fonts that are stored locally speeds up the site loading?

• How to manage permissions on a shared volume for OSX and ubuntu

  - by gentmatt

  On my mac I'm using an unjournaled HFS partition to share files between OSX 10.8 and Ubuntu 12.04. It was a nice thought at first, because Time Machine will automatically backup the volume in OSX, but I soon noticed that OSX and Ubuntu mess with the permission in a way that makes things messy for me. So, in order to fully view and change files, I keep using chmod to apply permissions that which will allow me to fully use a document. But I don't understand why I have to keep applying changes over and over. Is possible to set some kind of permission permanently so that both operating systems will respect permanently? I guess 777 will work, but I thought that this is not a smart thing to do. But as long as 'others' does not get full access (third seven), I see a lock icon on the file in ubuntu.

• Why after each restart, my local .NET sites take time to load for the first time?

  - by Saeed Neamati

  I'm developing sites based on .NET platform. I usually deploy these sites on my local IIS, so that I can test them and see their functionality before going live. However, each time I restart windows, it seems that sites take a long time to run for the first time. I know about JIT and I'm also aware of this question, but it doesn't answer my question. Does JIT happens every time you restart windows? Is it related to creation of w3wp.exe process? Why sites are so slow for the first request after each restart?

• KVM switching from lower resolution system resets Ubuntu high resolution

  - by Ed Manet

  I'm running 12.04 desktop on my main desktop and it's hooked to a KVM (IOGear miniview) that shares the peripherals with a SLES 11 machine. The SLES 11 machine can't get the same resolution as the Ubuntu machine because of different graphics hardware. If I switch from Ubuntu to SLES and stay there too long, when I switch back to Ubuntu the screen resolution on Ubuntu is reset to the same as SLES. I can get it back easily just opening the Displays configuration; it immediately resets to the high resolution as soon as the Displays window opens. But all my open windows have been maximized and it's a P.I.T.A. having to resize them all again. How do I get it to just stay at the high resolution between switching between systems? Is there a setting in the Xorg conf file I need to set?

• How to effectively gather info about how players play my HTML5 game?

  - by Bane

  I'm finishing another HTML5 game, and this time I'd like to do some spying business on the players... Mostly just basic stuff: when they are playing, for how long, what upgrades they are buying the most and so on. Now, my first idea was just to collect this information during the gameplay, and then have a Javascript function fire when they close the tab/browser, and said function would send it to my server via Socket.io. This, of course, wouldn't work, because anyone who takes a look at the code would realize it and could start sending a tonne of false info which would mess up my statistics. Questions: Is there a way to effectively do this? If yes, what kind of info should I be looking for, aside from stuff I already mentioned?

• What makes for the ideal project? [closed]

  - by Hans Westerbeek

  I try to be careful when accepting assignments, to avoid mutual disappointment. So, I started to come up with a list of things that I consider ingredients for The Ideal Project: (in no particular order) What did I miss? What did I get wrong? Team size < 6 persons to avoid having too many meetings Team members must be dedicated to the project Gut-feeling-estimate (made by developers) of running period does not exceed 4 months. Projects longer than that tend to become open-ended, and are therefore not projects. Has a Product Owner who has mandate and is well-respected at their own company and who has a real interest in the long-term success of the project. Has no technical involvement from people that are not on the team. (yes that's you, Mr Architect That Doesn't Code) All the usual about quiet working conditions Exciting subject matter. Content management is just not as cool as controlling robots :)

• "make" and "make install" never work

  - by Nirmik

  I have been trying it from a long time now and this time it got my nerves... The commands make and make install used to install a program from an extracted tar ball never work for some reason... The make command gives me the error- make: *** No targets specified and no makefile found. Stop. and the make install command gives me the error make: *** No rule to make target `install'. Stop. Why are these commands not executing? What should I do to solve this issue?

• Does Ubuntu Touch consume less power than Android?

  - by Eduard Florinescu

  One of the problems of new OSs is power consumption. That is because power and performance requires a lot of tweaks and experience with the kernel, drivers and OS code-base on one hand, and a lot of extensive long-term test and quality assurance on the other hand. Given that Android is a rather old and established OS I saw that it has pretty good power consumption. Phoronix does this kind of comparissions but I was not able to find much about Ubuntu Touch. Does Ubuntu Touch consume less than Android, do you have data on some platforms compared?

• Uninstalling application built from source

  - by Nik

  I know that Ubuntu has come a long way in helping new users to get used to their linux system..and making things as easy as possible. One most important aspect is installing and uninstalling applications in ubuntu. Thanks to Ubuntu Software Center it is a breeze! However I noticed that when I compiled and installed a game from its source (battleship), it does not appear under the history tab in the Ubuntu Software Center. And also you cannot uninstall it through the software center but have to resort to the command line to do this. I do not mind doing it however I am sure some other users might not be comfortable with this. Is this a bug?

• Tips for a first year CS student looking for a summer internship to gain experience?

  - by Matt

  Hello all, I am a first year CS student and my programming experience is only what I have obtained in my computer programming I and II classes this school year. (console applications in C++) I want to find a summer job/internship that would help me build my skill set. Being that I am still such a beginner pay is not a concern, minimum wage would be nice, but as long as I am learning, I really don't care. My current resume just lists a bunch of random jobs i've had in the past (burger king, summer camps, best buy, etc.) Does anyone have any tips (places to look? things to put on resume?) that might help me?

• Job Search Engine Url Structure Issue [closed]

  - by Justin

  Possible Duplicate: What is the best stucture of SEO friendly URL? I am working on a job board, and i'm trying to figure out a good design for URL structure. Some things that I have found through research: 100 - 150 Chars long is ideal 3-5 words in your url, according to Matt Cutts Use .htaccess to force clean urls Do not duplicate data (important) Clean and precise, describing the content Use hyphens On the homepage, I try to detect the users location based on IP, but this isn't always accurate, and not always reliable. So until they put in their city/location, I can't always use this structure but this is potentially work-able. For Searching, a form post to a results page: domain.com/jobs/[city]/[search] ie: domain.com/jobs/toronto/sales manager/ OR domain.com/search/jobs/toronto/sales manager/ or do I remove the word JOBS and just use Search. I trying to keep good search terms in the URL, but also keep it clean and concise. Can someone give me some feedback and thoughts to 'why'...

• Very few visitors on Analytics: incorrect setting?

  - by Akaban

  it's quite a long time Analytics is making me crazy: I have a 2 years old website, started with Aruba (an Italian provider) and then transfered on Hostgator. It's a blog Wordpress + MyBB forum, and on both the platforms I've the Analytics code in the footer. The problem is that the stats on Analytics are simply ridiculous compared to the numbers reported by the Aruba (before) and Hostgator (then). I think that the numbers of Aruba/Hostgator are correct, simply because just the daily users connected on the forum is higher than the Analytics numbers. I know it's a really confused request, but maybe you can help me to understand what's the problem.

• FormatDate in Display Item Form Webpart

  - by H(at)Ni

  I've faced an issue that I wanted to display the date in the format of ('MMMM dd') that is retrieved from a sharepoint list in an arabic site collection. So, after googling this issue, I've found out that a possible solution to my poblem is using the function ddwrt:FormatDateTime that can be used as long as you'll include the following namespace xmlns:ddwrt="http://schemas.microsoft.com/WebParts/v2/DataView/runtime" My purpose was solved by writing this line of code in my xsl code behind for the webpart : ddwrt:FormatDateTime(string(@StartDate),3073,'MMMM dd') but that worked only if the webpart is inserted into an English site . After trying to search but in vain, I started to use my guesses that ended up doing something like that: ddwrt:FormatDateTime(ddwrt:FormatDateTime(string(@StartDate),3073,'dd/MM/yyyy'), 3073, 'MMMM dd') And the cause of the problem was that sharepoint parses the date as 'MM/dd/yyyy' which I think could be related to server regional settings, so I had to force it to parse the date in arabic-Egypt format as 'dd/MM/yyyy' in order to get the correct 'Month Day' format as expected.

• High I/O wait after login

  - by Jackson Tan

  I've noticed that the ubuntuone-syncdaemon hogs up the hard disk every time I log in to Ubuntu (10.04). This takes up to two or three minutes, which makes Ubuntu insufferably slow. Opening Firefox is okay, but the browser is constantly greyed out and lags horribly. Given that I often shut down my laptop when I don't use it (about 3 to 4 times a day), this makes Ubuntu lose much of its lustre because of its long boot time. Is this a normal behaviour of Ubuntu One? Is it intended? Note that I've actually posted this in the forums here, but I received only few replies.

• Patches and translations

  - by Chris Wilson

  When changing a string of text as a part of a patch, how should the translation in the .po files be handled? For example, a recent paper cut I've worked on involved changing the string "Reboot Anyway" to "Restart Anyway" when gnome-session detected applications still running during restart. When I greped for the offending string, I found not only the string on the Gtk button, but identical strings in a long list of .po files which I later learned contained translations. The format of these translations of along the lines of msgid:Reboot Anyway <translated text> Changing the text of only the button would results in a discrepancy between the text on the English button and the translation, and changing the msgid line would result in a similar situation. How should I raise the issue that new translations are needed? I know this is a trivial problem in this example, but there are other such bugs that involve rewriting entire paragraphs of text.
