  • Can I uninstall and reinstall Ubuntu Software Center?

    - by schonjones
    Since migrating to a true install and upgrading to 12.04 I have had several problems that seem to relate to the Ubuntu Software Center. Hanging at applying changes and blank screen on screen lock only when it is running, for instance. My question is: Can I safely uninstall and reinstall Ubuntu Software Center and could this possibly fix those problems or are they just bugs I have to wait for updates for?

  • Reduce weight in healthy way - Day 2

    - by krnites
    My second day of reducing weight and it seems most of the blog are correct in saying that you can reduce weight if your calorie consumption is less than what you burn. In one day I have lost 1 lbs without doing anything. My current weight is 177.4 lbs. Yesterday I ate small portion of dinner that I used to eat that also around 7 PM. Normally I eat my dinner around 10 PM and withing 2 hour of eating I go for sleep, but yesterday I ate around 7 PM and went for sleep only after 12.On my second day I have eaten noodles and 3 eggs in breakfast and sesame chicken ( I love it) and fried rice in lunch, I still have not gone for running but had plan to go for running and then swimming. I hope it will at least burn the calories that I had taken. On some site it was written that a normal men body needs around 2000 Calorie a day. So if I am eating less than 2000 calorie ( noodles + 3 eggs = 400+200, rice + sesame chicken = 1300, total = 1900) and burning around 300 calorie, my total calorie intake will be 1600 which is less than what my body needs. So most probably by tomorrow I should come under 176 lb bracket.Apart from counting the calorie that I am taking in everyday and approx number of calorie that I am burning everyday, I had also starting tracking my physical activities on my mobile. I have got a beautiful Samsung Focus S Windows 7.5 mobile. And after browsing through the market I have downloaded couple of health Apps.1. 6 Week training - this has set of exercise and lets you choose the number of sets you want to do for all exercise. Its focus on your core muscles.2. Fast food Calories - This apps has all the fast food chain listed and give the calorie count of each of the food item available on there menu. Like for Burger King's French Fries Large (Salted) contains 500 Calorie.3. Gym Pocket Guide - Contains instructions for different kind of exercise and tells a right way of doing them.4.  RunSat - kind of GPS based application. Its mark the distance you have run, shows the path you have taken on a map, total calorie burnt, laps completed. I love this apps.5. Stop Watch I also have noticed that If I am running in GYM and have television in front of me where a movie or serial is going on which I like,  I normally didn't notice the time. Most of the time running on treadmill is very boring, but if some music video is playing or some kind of sitcom is going, I can run for  a hour or half.So on day 2 I have lost 1 lbs and had learnt that calorie intake should be less then calorie burnt for a given day.

  • How to troubleshoot a wireless networking regression?

    - by fluteflute
    I've been experiencing this perhaps slightly odd bug. It works flawlessly in Lucid, but not in Maverick and Natty. I find it seems to work when I'm booting a partition everyday (as I do for my main 10.10 partition) but for my 11.04 testing partition it's a real pain - usually refusing to connect. So given that I have both a working (10.04) and not-working (10.10 and 11.04) installs, how can I troubleshoot my problem?

  • Windows Server 2003 network boogey men every DBA should know

    - by merrillaldrich
    Recently I was again visited by my old friends TCP Chimney and SynAttackProtect . (Yeah, sometimes I feel like I mostly blog about 5-year old problems, but many of us as DBA's have to work on older versions or older systems, and so repeat older problems :-). This has been written about before, but as I BinGoogled around I noticed you are more likely to find the documents if you search for the cause, and not the symptoms. Most people who face a problem, of course, know the symptoms but not the cause....(read more)

  • Physic engine for snooker/billard game

    - by Marc Gillé
    I think most billard/snooker games have a lot of problems with their physic engines. They are far away from realistic and you can't really enjoy the game (especially when snooker is your hobby :) ) So I want to try to make an own physic engine (and own snooker game). I think the physic engine is the most important part of such a game. So my question is: Do anybody know an open physic enginge I can start with? Is there any literature about such physic problems?

  • How do I maintain a really poorly written code base?

    - by onlineapplab.com
    Recently I got hired to work on existing web application because of NDA I'm not at liberty to disclose any details but this application is working online in sort of a beta testing stage before official launch. We have a few hundred users right now but this number is supposed to significantly increase after official launch. The application is written in PHP (but it is irrelevant to my question) and is running on a dual xeon processor standalone server with severe performance problems. I have seen a lot of bad PHP code but this really sets new standards, especially knowing how much time and money was invested in developing it. it is as badly coded as possible there is PHP, HTML, SQL mixed together and code is repeated whenever it is necessary (especially SQL queries). there are not any functions used, not mentioning any OOP there are four versions of the app (desktop, iPhone, Android + other mobile) each version has pretty much the same functionality but was created by copying the whole code base, so now there are some differences between each version and it is really hard to maintain the database is really badly designed, which is causing severe performance problems also for fixing some errors in PHP code there is a lot of database triggers used which are updating data on SELECT and on INSERT so any testing is a nightmare Basically, any sin of a bad programming you can imagine is there for example it is not only possible to use SQL injections in literally every place but you can log into app if you use a login which doesn't exist and an empty password. The team which created this app is not working on it any more and there is an outsourced team which suggested that there are some problems but was never willing to deal with the elephant in the room partially because they've got a very comfortable contract and partially due to lack of skills (just my opinion). My job was supposed to be fixing some performance problems and extending existing functionality but first thing I was asked to do was a review of the existing code base. I've made my review and it was quite a shock for the management but my conclusions were after some time finally confirmed by other programmers. Management made it clear that it is not possible to start rewriting this app from scratch (which in my opinion should be done). We have to maintain its operable state and at the same time fix performance errors and extend the functionality. My question is, as I don't want just to patch the existing code, how to transform this into properly written app while keeping the existing code working at the same time? My plan is: Unify four existing versions into common code base (fixing only most obvious errors). Redesign db and use triggers to populate it with data (so data will be maintained in two formats at the same time) All new functionality will be written as separate project. Step by step transfer existing functionality into the new project After some time everything will be in the new project Some explanation about #2, right now it is practically impossible to make any updates in existing db any change requires reviewing whole code and making changes in many places. Is such plan feasible at all? Another solution is to walk away and leave the headache to someone else.

  • Spotlight on Words

    Linguists will tell you that there is no way to measure the importance of words to the development of man. Whether this is an exaggeration or an understatement, it is clear that everyday life would halt instantly without the use of words. Even the people of Dallas, who know how to communicate much without the use of words, would not be able to do anything without speaking with each other.

  • Why do I always think I know much less than others? [closed]

    - by John Kenedy
    I have been in programming since primary 6. Since the time DOS comes, I have been doing programming in quickbasic 4.5, then to VB 6, then to C#. In between I also do programming in C++. But every time I open Stack Overflow and trying to help others answering their problems, it seems that I know nothing. I feel that I am so stupid even I have been in programming for so long. I would shock reading all the questions and unable to find any clue. Is technology moving too fast that left out me? I feel that technology changes too fast and I can't keep up, when I know ASP.NET web form, MVC is out, when I know MVC, android/iphone/HTML5 app is popular. It seems that I am chasing something and never reach 'it'. I don't know whether this is correct place for me to talk about this. I just wish to listen to opinion like you, how do you think technology should grow instead of recreating language, adding bug here and there to let programmer figure it out, while big company share the solution among themselves. This is exactly how I feel. The simple example is how do you think why doesn't Dictionary<> in .NET provide iterating the object using index? Why must we use Key or GetEnumerator(). Developer has to google and read wasted hour of hour of time to find pieces of hack code to use reflection to achieve reading from index. Where developer will keep it as collection and valuable code. HOwever when times come, everything changes again, developer has to find answer for new silly problems again! Yes, I really hate it! I hate how many big companies are playing with the developer by cutting a big picture into small puzzle and messing it up and asking developer to place it together themselves. As if they are creating problems for us to solve it, so we are unable to grow upfront, we are being manipulated by those silly problems they have created. Another sample would how difficult to collect Cookies from CookieContainer without passing the URL, yes without the URL and I WANT to get all cookie in the cookiecontainer without knowing the URL, I want to iterate all. Why does micros0ft have to limit me from doing that?

  • What are the common pitfalls that would stop Authorised Key SSH access, and how do I find and correct for them?

    - by Ashimema
    EDIT: This question was reworked to make it more useful to the community and less specific to me. Questions seem to come up reasonably often regarding ssh and problems with authorised keys access, but very few seem to have a clear answer anywhere; Server keeps asking for password after I've copied my SSH Public Key to authorized_keys ssh not accepting public key how do I use ssh with key access in 11.10 passwordless ssh not working So, In the communities opinion, what is the tried and tested method for getting to the bottom of such problems?

  • Connect Digest : 2011-03-12

    - by AaronBertrand
    Background Last year, I came to a very tough decision that I would cease publicizing Connect items in an attempt to drive up votes and get important issues fixed. This was almost entirely due to a couple of MVPs criticizing me for raising awareness of certain Connect items instead of letting them be found "naturally." I wasn't sure what world they were living in, where droves of everyday end users just happened to stumble upon Connect items without any prompting. I suppose it could be said that the...(read more)

  • How often do you use data structures (ie Binary Trees, Linked Lists) in your jobs/side projects?

    - by Chris2021
    It seems to me that, for everyday use, more primitive data structures like arrays get the job done just as well as a binary tree would. My question is how common is to use these structures when writing code for projects at work or projects that you pursue in your free time? I understand the better insertion time/deletion time/sorting time for certain structures but would that really matter that much if you were working with a relatively small amount of data?

  • Beyond the Great Wall

    This highway is traversed everyday by roughly 338 million Chinese Internet users. With the largest population in the world of 1.3 billion, the increase of Chinese Internet users in the next years would undoubtedly be viably incremental.

  • Book Readers As Envisioned Circa 1935

    - by Jason Fitzpatrick
    This early 20th century sketch showcases the future of books; thankfully the actual delivery of the concept proved to be a bit more lap-friendly. The sketch is from the April, 1935 issues of Everyday Science and Mechanics and presents a vision of book consumption that, thankfully, came to pass in a much more compact fashion that doesn’t require swapping rolls of film.
