• Ubuntu boot is slower than Windows 7

  - by Alex Bixel

  One of the reasons I installed Ubuntu (Wubi installer) was for a supposedly quick boot time. My boot time with Windows 7 is about 20-25 seconds, while my boot with Ubuntu is 30-40. I judged the boot times from the time after I selected the operating system on the initial selection menu and the grub menu, respectively. This is even after following all sorts of online guides to improve it. I've done driver profiling (and yes, I remembered to remove the "profile" edit in the grub file afterwards), I've cut a fair few startup programs out, and I've installed the preload package. But I'm still getting startup rates phenomenally slower than Windows 7. Any help here?

• Remote connection problem.

  - by Woody

  Hello I have ubuntu 10.04 installed with mysql on it and I have a problem with remote connection. When I connect through putty it works but sometimes it looks like it hangs for example when I execute the command ln --help. Also with MySQL connection When I execute a simple query like show processlist; it works, but for example select * from table not always, if the table doesn't have many rows it works but if it has let's say more than 20 the query looks like it keeps working and never ends. It's connected but I can't do many things remotely. Added: I connect using putty from other windows pc, server is not overloaded. when i work at the same time directly on ubuntu i can do everything. Remotely not.

• Victory rewards in digital CCG

  - by Nils Munch

  I am currently polishing a digital CCG where people can play against friend and random opponents in a classical Magic the Gathering-like duel CCG. I plan to award the players with 20 ingame currency units (lets call them gold) for each hour they are playing, 50 for each day they are playing and X for each victory. Now, the X is what I am trying to calculate here, since I would prefer keeping the currency to a certain value, but also with to entice the players to battle. I could go with a solid figure, say 25, for beating up an opponent. But that would result in experienced players only beating up newly started players, making the experience lame for both. I could also make a laddered tier, where you start at level 1, and raise in level as you defeat your opponents, where winning over a player awards you his level x 2 in gold. Which would you prefer if you were playing a game like this. There is no gold-based scoreboard, but the gold is used to purchase new cards along the way.

• ubuntu 14 painfully slow on dell r200

  - by sirmonkey

  I didn't notice it at first. The machines (there is 20 plus) are to be used a simple file servers. It wasn't until samba just wouldn't act right that I installed a desktop gui and started more diagnoseing the problem did I catch the slow preformance... I've tested 4 servers they all suck. And windows 7 runs fantastic on them. I have Google and searched. But nothing to explain this. The easy test is dmesg is so slow you can almost read it. I'm guessing it's an apic or cpu power management issue. What output would you all like????? It is a core2 machine with 4Gb of ram. On board data.

• Looking for a very subtle unit testing example

  - by Stéphane Bruckert

  In the context of Continuous Integration, I need to teach unit testing to a 20-people audience of programmers. Everything will be all right, but I am still trying to find the perfect unit testing example. More than writing tests like a robot, I want to show that unit testing can help prevent very subtle errors. I am thinking of the following scenario to happen when doing a live TDD demo: the test cases would already be written, we would have to write methods together, most of us would naturally have forgotten to handle a specific case for a method, everyone would then be surprised, when seeing that all tests don't pass, the failing test would make us think more and realize that we forgot an important case. My question will probably finish as "too broad" or "not clear what you are asking", but we never know, one of you might have a great idea. Your answer can use Java and JUnit, though any other language will be fine since only the idea will matter.

• Writing drivers for a printer?

  - by user828584

  My goal is to be able to fax 20 page pdf documents for free. I've looked online, and there are some free fax services, but all of them have their limits. I do have an old fax machine, but the documents that need to be faxed are on the computer, and to print them would be far from free. Unfortunately, the only way to send a fax with the machine is by scanning it. What's strange is that it can scan to the computer and print from it, but it won't fax from it... :(. Is it possible to write something (preferably C#, but it's going to take some learning anyway) that will allow me to send a fax from the computer? I have very little software experience, and none in anything like this, so I have no idea where to start. If it is possible, where can I find all the information needed to write the program?

• Website Stopped Showing From Google Search Results Sunddenly

  - by Aman Virk

  I have a design and development blog http://www.thetutlage.com (1.5 years old), which was doing really well in Google search as I was getting over 70% of my traffic from Google. Now suddenly from last two days it reduced the amount of traffic from 70% to 20% and also when I am trying to search for the exact posts that I can created even after appending my website name to it does not show any results for that. Sample Search Text: JQuery Game Programming Creating A Ping Pong Game Part 1 I have post with exact same title and it does not show it on Google search anywhere. I am totally shocked, I write my own unique content and follow Google guide lines like bible. Also there is no message under my webmasters account stating any problem or error.

• If Ubuntu freezes when running off a USB drive, will it freeze after full installation?

  - by fearoffours

  I'm planning to install Ubuntu on an aging Compaq Presario V5000. I've established that the Unity desktop is not suited to this laptop, and am now using the standard (Gnome?) desktop. I'm grappling with ndiswrapper and my wireless chipset. But I'm still running it off a USB drive before I take the plunge and install properly to my internal HD. Part of my reticence in completing the installation is I'm experience freezes after about 10-20 minutes usage. Is this likely to be in any way related to running it off the USB drive?

• Retrieving snapshots of game statistics

  - by SatheeshJM

  What is a good architecture for storing game statistics, so that I can retrieve snapshots of it at various moments? Say I have a game, and the user's statistics initially are: { hours_played = 0, games_played = 0, no_of_times_killed = 0, } When the user purchases something for the first time from within the game, the stats are { hours_played = 10, games_played = 2, no_of_times_killed = 5, } And when he purchases something for the second time, the stats are { hours_played = 20, games_played = 4, no_of_times_killed = 10, } Let me name the events as "purchase1" and "purchase2" How do I model my statistics, so that at any point in the future, I will be able to retrieve the snapshot of the statistics at the time when "purchase1" was fired. Similarly for "purchase2" and any other event I will add. Hope that made sense..

• What's the best platform for blogging about coding? [closed]

  - by timday

  I'm toying with starting an occasional blog for posting odd bits of coding related stuff (mainly C++, probably). Are there any platforms which can be recommended as providing exceptionally good support (e.g syntax highlighting) for posting snippets of code ? (Or any to avoid because posting mono-spaced font blocks of text is a pain). Outcome: I accepted Josh K's answer because what I actually ended up doing was realizing I was more interested in articles than a blog style, getting back into LaTeX (after almost 20 years away from it), using the "listings" package for code, and pushing the HTML/PDF results to my ISP's static-hosting pages. (HTML generated using tex4ht). Kudos to the answers mentioning Wordpress, Tumblr and Jekyll; I spent some time looking into all of them.

• Better Embedded 2012

  - by Valter Minute

  Il 24 e 25 Settembre 2012 a Firenze si svolgerà la conferenza “Better Embedded 2012”. Lo scopo della conferenza è quello di parlare di sistemi embedded a 360°, abbracciando sia lo sviluppo firmware, che i sistemi operativi e i toolkit dedicati alla realizzazione di sistemi dedicati. E’ un’ottima occasione per confrontarsi e, in soli due giorni, avere una panoramica ampia dall’hardware a Linux, da Android a Windows CE, dal .NET microframework a QT, senza troppi messaggi commerciali e con un’ottima apertura sia alle tecnologie commerciali che a quelle free e open source. Io parteciperò come speaker, parlando di Windows CE, ma anche come spettatore interessato a molte delle track di un programma che si va popolando e diventa mano a mano più interessante. Se volete cogliere l’occasione per visitare Firenze (che già sarebbe un motivo più che sufficiente!) e parlare di embedded, contattatemi perchè come speaker posso fornire un codice sconto che vi farà risparmiare un 20% sul prezzo della conferenza (che già è vantaggiosissimo, vista la quantità di contenuti dedicati all’embedded). Arrivederci a Firenze!

• Ubuntu reports low battery capacity on my Dell Vostro

  - by Jeff

  I have a Dell Vostro 1500. Before I wiped Windows XP off my hard drive in 2009, I had a full ~7 hrs battery capacity. I installed Ubuntu 9, and the capacity immediately dropped to about 27% (and has since decreased to about 11%). I couldn't figure out what to do, so I've just lived with the 20-30 minute battery life ever since. I upgraded to Ubuntu 10, and the issue remained. I wiped my hard drive clean again and installed Ubuntu 11, and the issue still remains. I tried what they told me in the forum here, but it didn't do anything. Is it possible for a battery to suddenly lose most of its capacity?? Or is there a bug in the power management software?

• Generation 4 Modular Data Center

  - by kaleidoscope

  Microsoft’s launched Generation 4 Modular Data Center design at the PDC 09 - The 20-foot container built on container-based model. Microsoft says the use of server-packed containers – known as Pre-Assembled Components (PACs) – will allow it to slash the cost of building its new data centers. Completely optimized for outdoor use, with a design that relies upon fresh air (”free cooling”) rather than air conditioning. Its exterior is designed to draw fresh air into the cold aisle and expel hot air from the rear of the hot aisle. More details can be found at: http://www.datacenterknowledge.com/archives/2009/11/18/microsofts-windows-azure-cloud-container/   Rituraj, J

• Unity3D problem. Bullets fall down instead of flying like they should

  I used this tutorial as a reference. http://www.youtube.com/watch?v=3L8eaoyZ0Go My problem is that whenever I play the game, EVERYTHING works but the bullets. It just falls down instead of flying forward. This is the flash version of the game: http://v1k.me/swf/ Can some one help me out? Should I upload the project? This is my "Shoot.js": public var bulletPrefab : Transform; public var bulletSpeed : float = 20; function Update() { if(Input.GetMouseButton(0)) { if(bulletPrefab || bulletSpeed) { var bulletCreate = Instantiate(bulletPrefab, GameObject.Find("SpawnPoint").transform.position, Quaternion.identity); bulletCreate.rigidbody.AddForce(transform.forward * bulletSpeed); } } }

• Bug once in a while,but high priority

  - by Shirish11

  I am working on a CNC (computer numerical control) project which cuts shapes into metal with help of laser. Now my problem is once in a while (1-2 times in 20 odd days) the cutting goes wrong or not according to what is set. But this causes loss so the client is not very happy about it. I tried to find out the the cause of it by Including log files Debugging Repeating the same environment. But it wont repeat. A pause and continue operation will again make it to run smoothly with the bug reappearing. How do I tackle this issue? Should I state it as a Hardware Problem?

• Which programming career path fits my terms? [closed]

  - by Goward Gerald

  I am sick and tired of my enterprise development job, I need some programming direction like this: Demanded in jobs-market Demanded in freelance market Can use Ubuntu as development environment Not enterprise. Standalone, mobile, web-development, anything, just not enterprise. Basically, I need a programming direction which doesn't need 20 developers, terribly big databases systems and long going projects with intense long-term support, I don't want enterprise job where a lot of people are working on one terribly big project and do modules to it all day long. Instead, I need something where: Projects change pretty often Projects are little, or medium-sized (in terms of code, modules and people working on it) but still not enterprise-sized Possible for freelance, solo-development, or at least requires a team of 3-4 programmers. Not like in enterprise where you feel like a drop in the sea with your 50 classes while system itself has hundreds of classes. Suggestions please?

• F# &ndash; It&rsquo;s time to grow up baby.

  - by MarkPearl

  In the last few months since I started learning F# I have begin to notice an increase in the number of people blogging about the language. Sure, it could just be that I am noticing it more because I am actively looking out for questions and blog posts, but even in my day to day reading of Code Project Daily News and Stack Overflow questions there seems to be increased activity around the language. So what sparked this post? Well, today today I logged in and saw that the latest podcast by DNR was on F# and then immediately afterwards I received an email from CodeProject with a great article comparing F# and Scala. Currently, as of this blog posting (21 May 2010) F# is ranked on the tiobe site at position 43, but I am willing to put money on it that in the next few tiobe ratings this ranking will continue to rise till F# will be a top 20.

• Identify my terminal session that started a particular process

  - by Sam

  I'm using Gnome on Ubuntu. I often have 8-20 terminal sessions open and in some of them I have su'd to a different user. The specific problem that caused me to write this query happens when using git status, but this is more general issue. git status will tell me I have an uncontrolled file .foo.java.swp. This means that in one of my terminal sessions I have vi open on foo.java. I need a script or tool that would tell me in which terminal session that vi is running. I can do a "ps aux | grep vi" to pretty easily find the pid of the particular vi. It would be nice if the tool highlighted the terminal on my task bar in some way. Thanks. -Sam

• How much time do you spend in this site with work on your desk?

  - by David Conde

  This is a simple question, because I want to see if there is a collective tendency to do this: How much time do you spend snooping around in StackOverflow, Programmers, and all those heavenly sites even when having work on the desk? Are these sites becoming facebook, in our case? I used to enter facebook from time to time... it's been like 20 days now and I dont even care about it. All I want to see is what are the latest post of my geeky friends around here..! Is this collective?
