• Scheme vs Haskell for an Introduction to Functional Programming?

  - by haziz

  I am comfortable with programming in C and C#, and will explore C++ in the future. I may be interested in exploring functional programming as a different programming paradigm. I am doing this for fun, my job does not involve computer programming, and am somewhat inspired by the use of functional programming, taught fairly early, in computer science courses in college. Lambda calculus is certainly beyond my mathematical abilities, but I think I can handle functional programming. Which of Haskell or Scheme would serve as a good intro to functional programming? I use emacs as my text editor and would like to be able to configure it more easily in the future which would entail learning Emacs Lisp. My understanding, however, is that Emacs Lisp is fairly different from Scheme and is also more procedural as opposed to functional. I would likely be using "The Little Schemer" book, which I have already bought, if I pursue Scheme (seems to me a little weird from my limited leafing through it). Or would use the "Learn You a Haskell for Great Good" if I pursue Haskell. I would also watch the Intro to Haskell videos by Dr Erik Meijer on Channel 9. Any suggestions, feedback or input appreciated. Thanks. P.S. BTW I also have access to F# since I have Visual Studio 2010 which I use for C# development, but I don't think that should be my main criteria for selecting a language.

• Choosing a (browser) game environment [closed]

  - by Iain

  I apologise in advance if this post is something you've heard a million times already or seems like a trolling attempt. I just want some advice and I'm coming up short with my own Google searches. Basically, I would like to start learning some game development in my own free time (nothing serious, just purely as a hobbyist for fun). I'd like to know what the communities opinions are on the old HTML5/Javascript v Flash argument but purely from a game development perspective. I know people say Flash is dying because of issues like SEO, memory/bandwidth usage and Apple dropping it on tablet and mobile devices, so is it worth me dedicating my free time to learning to use Flash/AS3 for game development or should I focus on HTML5/Javascript? At the moment, I'm not sure HTML5/Javascript is mature enough or has the support tools that Flash does (framework, IDE, etc) and there seems to be a lot more resources online for beginner Flash/AS3 programming. When I'm reading tutorials online for Flash/AS3 I always have it in the back of my head that I'm wasting my time because it won't be around in a few years and I should be investing that time learning HTML5/Javascript. Thoughts? Disclaimer: I'm not trying to spark a flame war or troll anyone - I believe in the right tools for the job and I don't want to waste my time learning something that won't be around in a few years.

• Web Hosting Checklist

  - by Chris

  Hello, I am a web developer that is starting to look into hosting his own website. I would like to showcase my programming skills (PHP, MySQl, C#, Wordpress). My knowledge of languages I am OK with but the actually hosting site is where my knowledge starts to get a little shaky. I know the basics (bandwidth, sub-domains, re-write rules) but I would love your input, to help me formulate a check list of certain web-hosting services that I should be on the look-out for. Also I was wondering if there were any reliable hosting providers who give you the option to host both c# code-behinds and PHP code. As I would like to have two versions of my site, one in C# and one in PHP the hope is that if I need to look for another job this website will help me show possible employers my server side knowledge. I hope this is enough info, I did some researching online but found a bunch of unless articles and I've always have had luck on the StackExchange sites. So hopefully you, can help me. Thanks alot.

• How do I make money from my FOSS while staying anonymous?

  - by user21007

  Let's say that: You have created a FOSS project that other people find useful, perhaps useful enough to donate to or pay for modifications to be done. It is a perfectly legitimate and innocuous software project. It has nothing to do with cryptography as munitions, p2p music, or anything likely to lead to a search warrant or being sued. You want your involvement to stay anonymous or pseudonymous. You would like to receive some money for your efforts, if people are willing. Is that possible, and if so, how could it be done? When I talk about anonymity, I realize that it is necessary to define the extent. I am not talking about Wikileaks style 20 layers of proxies worth of anonymity. I would expect a 3 letter agency to be able to identify the person easily. What is wanted is shielding from commercial competitors or random people, who would not be expected to be able to get the financial intermediary to divulge your details just by asking for them. Why would you want to stay anonymous? I can think of several valid reasons, maybe you operate a stealth mode startup and don't want to give your competitors clues as to the technology you are using. Maybe it is a project that has nothing to do with your daily job, is not developed there, but the company you work for has an unfair (and possibly unenforceable) policy stating that any coding you do is owned by them. Maybe you just value your privacy. For what it's worth, you intend to pay the relevant taxes in your country on any donations.

• How to Print From Metro Apps in Windows 8

  - by Taylor Gibb

  Printing has become an application aware feature in Metro applications. This makes the outcome of a print job different from application to application, but the question remains, how do you print? Using the Keyboard Not all apps support printing in Windows 8, a good example of one that does is Mail. So fire up the default Mail app select an email you want to print. When you are ready, go ahead and press the ctrl + P keyboard combination. This will bring up a list of available print devices on the right-hand side, you can use the up and down arrows to select a printer. You will get most of the options you are use to when printing, so once you have set up your preferences go ahead and hit the print button. Using the Mouse If you would rather use your mouse, move it to the bottom right hand corner of your screen, which will bring up the Charms bar, from here you will need to click on the devices charm. Using this will list your printers as well as other devices, so make sure you select a printer. That’s all there is to it.

• Looking for someone to point me in the right direction. I want to learn how to use hosted servers

  - by Leisure

  TL;DR: I want a Java program to run on a server, I want the server to forward a particular port from external to internal IP, I want store a few files on the server. Guides please. So I made a hack job Java program that acts as a server for my android application. It stores data in text files and HTML files, uploads them via FTP to my webhost, and manages socket connections (using port forwarding) with any phones connected. Right now I'm running it on NetBeans on my home computer. I know that it will probably slow down or crash once about 50 phones are connected at once. Is there any way I can run this program on a server with a high bandwidth? Can someone please find me a guide for that? I'm noob and don't know where to start looking. I seriously don't know anything about renting or using servers - I need a nice guide, and recommendations. My requirements for the server: Can handle about 2k socket connections at once Can run my Java code and store my txt files Can give me a port and an IP address so TCP/IP clients can be connected My budget: $50 CAD per month. Please someone set my ship sailing in the right direction, I really don't know where to look for resources.

• Download lastfm tags into mp3 comment or genre tag

  - by Meng Tian

  for a long time I dream to have a songs lastfm tags in my music library, so I can use them to quickly generate playlists. There used to be a way to do that in amarok 1.4, but it never was stable. Than there is MusicBrainz Picard's lastfm/lastfmplus plugin. It is partially fine, but I cannot manage to make it look ONLY for the lastfm tags and put them into comments/genre/whatever but it always hast to tag everything. And it isn't particularly good with it, especially with small bands, songs without album etc. My music library is rather well organised. Most of the tags are correct. I also have quite some songs without an album. And I don't want it to find the albums for those songs, since it'd mess up my album view. So it must not touch the fields track name, track number, artist and album. All I want is that the most popular lastfm tags get into the genre or comments tag of the mp3, separated by semicolons, commas or whatever. I think I remember a script that did this job, but I cannot find. Does anybody know if there is anything like this? Would it be to hard to write this, for example as Banshee plugin? Thank you

• Anyone been successful changing their career without having to start over from scratch?

  - by Awaken

  I posted a similar question on careeroverflow, but stackoverflow is just way more active and has way more users, so hopefully someone out there can help answer. I am currently an embedded developer in the defense/aerospace world for a big company. While I like the benefits and the pay, it just isn't keeping me happy. The Paul Graham article: How To Do What You Love really struck home. The problem I face are my golden handcuffs. When I look at jobs out there, they all want 5+ years experience in that language with expertise in framework/tool/server A,B,C, etc... I have worked in C and C++ on the job (in a real-time embedded environment) with some small things in C# and Java. I'm learning Ruby now to expand my knowledge, but I don't consider myself an expert in anything right now. I'd love to work on desktop applications or web apps. Is it possible for someone like me to make the switch without going back to the start line? I'd love to leave the huge bureaucracy and work with some great developers. I'd be willing to work late and take a modest pay cut, but that isn't so clear just from a resume. For those that have altered their career path, how did you do it? For those people who are in charge of hiring, what can I do to help myself?

• Agile Data Book from O'Reilly Media

  - by Compudicted

  Originally posted on: http://geekswithblogs.net/Compudicted/archive/2013/07/01/153309.aspxAs part of my ongoing self-education and approaching of some free time, yeah, both is a must for every IT person and geek! I have carefully examined the latest trends in the Computersphere with whatever tools I had at my disposal (nothing really fancy was used) and came to a conclusion that for a database pro the *hottest* topic today is undoubtedly the #BigData and all the rapidly growing and spawning ecosystem around it. Having recently immersed myself into the NoSQL world (let me tell here right away NoSQL means Not Only SQL) one book really stood out of the crowd: Book site: http://shop.oreilly.com/product/0636920025054.doDespite being a new book I am sure it will end up on the tables of many Big Data Generalists.In a few dozen words, it is primarily for two reasons:1) The author understands that a  typical business today cannot wait for a Data Scientist for too long to deliver results demanding as usual a very quick turnaround on investments (ROI), and 2) The book covers all the needed and proven modern brick and mortar offerings to get the job done by a relatively newcomer to the Big Data World.It certainly enables such a professional to grow and expand based on the acquired knowledge, and one can truly do it very fast.

• How do you structure your shared code so that it is "re-findable" for new developers?

  - by awmckinley

  I started working at my current job about 8 months ago, and its been one of the best experiences I've had as a young programmer. It's a small company, and both my co-developers are brilliant guys. One of the practices that they both have been encouraging is lots of code-reuse. Our code base is mainly C#, and we're using a centralized revision control system. The way the repository is currently structured, there is a single folder in which all shared class libraries are placed (along with unit tests for each library), and our revision control system allows for sharing or linking those libraries out to other projects. What I'm trying to understand at this point is how the current structure of the folder can be made more conducive for finding those libraries again. I've talked to the other developers about this, and they agree that it's gotten a little messy. I find that I am sometimes "reinventing the wheel" because I didn't realize that there was an existing piece of code that solved a particular problem. The issue is complicated further by the fact that we're sharing some code between ASP.NET MVC2, WinForms, and Windows CE projects, and sharing code between applications built against multiple versions of .NET. How do other people approach this? Is the answer in naming the libraries in a certain way or is it preferable to invest in some code-search software? Is the answer in doc comments? Should we be sharing libraries at all or should we simply branch the class libraries for re-use? Thanks for any and all help!

• Lexmark E240 printing issues

  - by NoamH

  I have Lexmark E240 laser printer. I have been using it with 12.04 (32bit) for 2 years with no significant issues. Since lexmark does not support this printer on linux, I used alternatives drivers that were suggested by the community, such as HP-lasterjet, E238, generic PS, etc. They all worked fine, more or less. After upgrading to 14.04 (64bit fresh install) I tried to configure the printer as before, but now I have problems. The test page is ok, but when printing, most of the times, the first page in the document will be printed very partially and in 300% zoom. Next page might be ok. If I turn off the printer and back on, the first page might be ok, but in the next print job, it will be broken again. I used all the above printer options. Same results. I did NOT install the lexmark drivers since they are intended for 12.04 and the package manager report that it is in "bad quality" (don't know why). Does anyone has any experience with this printer in 14.04 64bit ?

• Lack of PHP experience = reduced compensation?

  - by Jake Tacholsavacky

  I interviewed for a C++ position at this company, and while they say that I knocked my interview out of the park, they also say that I am too senior for the position. Instead they would like to offer me a job programming in PHP. Unfortunately my PHP experience is limited. Because of this, they are expecting me to take a significant drop in salary with the hope that I will master PHP within a year and be promoted at my first annual performance review. I don't believe that this is reasonable. I agree with Joel when he writes, "Don’t look for experience with particular technologies." If they thought I was such a superstar, then they should have realized that I am capable of being productive in PHP within weeks, not a year! It seems like just an excuse to underpay me. Notwithstanding the fact that I was insulted by this offer, I think that I would be taking on much more risk than they would be; they won't guarantee what my post-PHP salary would be. What does the Stack Exchange community think about this offer? Would you take it?

• Azure Search Preview

  - by Greg Low

  One of the things I’ve been keeping an eye on for quite a while now is the development of the Azure Search system. While it’s not a full replacement for the full-text indexing service in SQL Server on-premises as yet, it’s a really, really good start. Liam Cavanagh, Pablo Castro and the team have done a great job bringing this to the preview stage and I suspect it could be quite popular. I was very impressed by how they incorporated quite a bit of feedback I gave them early on, and I’m sure that others involved would have felt the same. There are two tiers at present. One is a free tier and has shared resources; the other is currently $125/month and has reserved resources. I would like to see another tier between these two, much the same way that Azure websites work. If you have any feedback on this, now would be a good time to make it known. In the meantime, given there is a free tier, there’s no excuse to not get out and try it. You’ll find details of it here: http://azure.microsoft.com/en-us/documentation/services/search/ I’ll be posting more info about this service, and showing examples of it during the upcoming months.

• Writing a DB Python or Ruby

  - by WojonsTech

  I am planning on writing a database. I know it's crazy and people will tell me there is no good reason to do so. I am really using it to get better at programming overall, this database wont be used in production. I am planning on writing it Ruby or Python. I have some experience with both languages, but no job or large project experience. I don't want this to be a this is better than that randomly I really need some facts. The things that I need to know are which of the language are better at the following things. Searching arrays/hashes? Sorting? Threading? Sockets? Memory management? Disk Reads/Writes? base64 encode/decode? Again this is just a project for myself. I will port it on github for the hell of it, but I don't expect it to be amazing or going up against mysql or mongodb any day.

• My new anti-patent BSD-based license: necessary and effective? [closed]

  - by paperjam

  I am writing multimedia software in a domain that is rife with software patents. I want to open source my software but only for the benefit of those who don't play the patent game, that is enthusiasts, small companies, research projects, etc. The idea is, if my code would infringe a software patent somewhere and a company pays to license that patent, they then lose the right to use and distribute my software. Now I detest license proliferation as much as anyone but I can't find an existing OSI approved license that does this. The GPL comes close, but it only restricts distribution, not use. I want to stop someone using my software should they obtain a patent license to do so. Does another license do this job? Is the wording below unambiguous? - I don't want a legal opinion, just whether it would be interpreted as I intend. Copyright (c) <year>, <copyright holder> All rights reserved. Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: [ three standard new-BSD conditions not shown here] * No patents are licensed from any third party in respect of redistribution or use of this software or its derivatives unless the patent license is arranged to permit free use and distribution by all.

• With Choice Comes Complexity

  - by BuckWoody

  "Complex" may be defined as "Having many steps, details or parts." Many of Microsoft's products, including SQL Server, can be complex. I'm stating what most data professionals already know - there's usually multiple ways to do things in SQL Server. For instance, to import some data into a table you can use graphical tools, SQLCMD, bcp, SQL Server Integration Services, BULK INSERT, even PowerShell, just to name a few tools at your disposal. That's really not the issue, though. The bigger issue is that there are normally multiple thought-processes, or methods, that you have available for a task. That's both a strength and a weakness. If things were more simple, you would have fewer choices. Sometimes that's a good thing. Just tell me what I need to do and I'll do it. However, your particular situation may not fit that tool or process, so having more options increases your ability to get your job done the way you need to do it. On the other hand, that's more for you to learn, which is harder. There's another side of this benefit/difficulty that you need to be aware of. Even if you're quite good at what you do, keep in mind that the way you know how to do something may not be the only way to do it. Keep your mind open to new possibilities, and most importantly - to new knowledge. SQL Server professionals teach me something new every day. So embrace the complexity - on balance, it's a good thing! Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

• Office arangement - comfort vs. teamwork?

  - by finrod

  Our team works in an open-space office. Luckily the cubicles are quite big (L shaped tables for everyone!), there is quite a lot of space so we are not sandwiched. Without going into further detail, there are comfortable spots (window), normal spots and stupid spots (near the corridor). Until recently, the development team of twelve engineers was seated so that all types of spots were occupied and we were all close together. In the old arrangement, verbal communication was very easy - half of the team was withing talking distance. The other half was like ten steps away. Often times I could ask, discuss, solve problems without leaving the cube. Most of the communication is work related, no bullshit or mental masturbation that would unnecessarily distract others. Now we have moved to another part of the building and have larger space to occupy. At this point, everyone could pick their spot. Naturally all stupid spots are left empty (for the poor newcomers to occupy bwehaha). In the new arrangement, the development team is stretched across the floor and some of the key engineers are seated 'far' from each other - definitely not within talking distance. I have yet to experience how this works out but am getting concerned that team work and communication may have been traded for personal comfort. Finally the questions... What do you think is better office arrangement? Such that allows for free verbal communication but trading for some developer's comfort, or such that potentially hinders verbal communication but makes developer's more comfortable in their spot? Or maybe it does not matter at all and we will evolve to be efficient in any arrangement? What is your personal experience? Note - yes I read books and posts how workplace is important in our job. However in this case - we are all still in open space and the difference between the different spots are not really groundbreaking. So I'm thinking the little comfort that few developers gain is not worth the loss of easy communication.

• How to ask the boss to pay for qualifications?

  - by adamk

  Hi, I'm working as a junior developer for a startup company, and have been working here around 7 months now. After 4 months, we had a late quarterly review, and just before the boss mentioned there was a training budget, and we should let them know what training we needed and they'd get it for us. I asked for some training at the time, but 3 months have passed without mention of it, and I have since learnt what I needed in my own time (I just can't stop learning new things!) I took on a new role recently, so have been given some cheap ($60) training for that however. Now the next review is approaching, and I would like to get Adobe Qualified Expert qualifications for ActionScript 3 / Flex. I was told by a contracted co-worker who had left that I should try to get the company to pay for this, as it's something they can tell potential investors as a selling point. My question is though; how do I approach this with my boss? I don't want it to sound like I'm looking for another job and want the qualifications to look elsewhere!

• Pros and Cons between learning to program on Windows and Linux and Macs

  - by Amumu

  I have been studying IT for 2 years and I'm going to graduate soon in this year (if everything goes well). I think it's time for me to choose a path to specialized into some fields of this large industry. Personally, I want to be a game programmer. But to be a game programmer, surely I have to invest my time to study Windows Programming, then DirectX and other programming techniques related to game. On the other hand, Linux seems promising as well. I am not sure about Game Programming on for it, but it seems become an expert for this OS, and by expert it's not about using the OS to become an administrator, but can do further than that, such as understand the OS to its essence and can produce applications for it. However, there's some obstacles in my view for this development path. Many of my friends think that Linux is based on free and open source, and if you follow it, as its name suggested: Free and Open Source, it means we also give away our software free. Otherwise, we will have to find a second job to make living. Currently, I think a viable way to make money on Linux is doing works related to client-server. Another way to developer my career is to become expert in developing business applications for companies. This is more on business, not on specialized IT fields so I am not really interested. Another alternative is programming on mobile devices, such as iPhone, Android and it seems very promising and easier to approach. Another way is to become a computer scientist and research on academic subjects such as AI, human-computer interaction, but this is far beyond my reach, so I won't invest my time on it until I feel I am experienced enough. That's all I can think of for now. I may miss a lot of things, so I need more opinions as input to get the big picture of the industry for my career path.

• Planning milestones and time

  - by Ignas

  I was hired by a marketing company a year ago initially for link building / SEO stuff, but I'm actually a Web developer and took the job just in desperation to have one (I'm still quite young and just finished 2nd year of University). From the 3rd day my boss realised that I'm not into that stuff at all and since he had an idea of a web based app we started to plan it. I estimated that it shouldn't take me longer than two months to do it, but as I was making it we soon realised that we want to add more and more stuff to make it even better. So the development on my own lasted for about 4 months, but then it became an enterprise size app and we hired another programmer to work along me. The guy was awesome at what he did, but because I was assigned to be programmer/project manager I had to set up milestones with deadlines and we missed most of them, because most of the time it was too much work, and my lack of experience kept me setting really optimistic deadlines. We still kept adding features and had changed the architecture of the application twice. My boss is a great guy and he gets that when we add features it expands the time frame in which things should be done so he wasn't angry at me nor the other guy. But I was feeling bad (I still am) that I suck at planning. I gained loads of experience from the programming side, but I still lack the management/planning skills which make me go nuts. So over the last year I have dedicated probably about 8 months of work to this app (obviously my studies affected it) and we're launching as a closed beta this month. So my question is how do I get better at planning/managing a project, how do you estimate the times? What do you take into consideration when setting goals. I'm working alone again because the other guy moved from the city. But I'm sure we'll be hiring to help me maintain it so I need to get better at it. Any hints, points or anything on the topic are appreciated.

• Obscure SPUtility.SendMail Behavior When Manually Passing in Mail Headers

  - by Damon

  There are two ways to send mail in SharePoint: you can either use the mail components from the System.Net namespace, or you can send email using SharePoint's SPUtility.SendMail method.  One of the benefits of the SPUtility.SendMail method is that it uses the mail configuration from SharePoint, so you can manage settings in Central Administration instead of having to go through and modify your web.config file.  SPUtility.SendMail can get the job done, but it's defiantly not as developer friendly as the components from the System.Net namespace.  If you want to CC someone on an email, for example, you do NOT have a nice CC parameter - you have to manually add the CC mail header and pass it into the SPUtility.SendMail method.  I had to do this the other day, and ran into a really obscure issue. If you do NOT pass the headers into the method then SharePoint sends the email using the From Address configured in the Outgoing Mail settings in Central Admin.  If you pass headers into the method, but do not include the from header, then SharePoint sends the mail using the email address of the current user. This can be an issue if your mail server is setup to reject an email from an invalid email address or an email address that is not on your domain.  The way to fix this issue is to always pass in the from header.  If you want to use the configured From address, then you can do the following: SPWebApplication webApp = SPWebApplication.Lookup(new Uri(SPContext.Current.Site.Url)); StringDictionary headers = new StringDictionary(); headers.Add("from", webApp.OutboundMailSenderAddress);

• How can rotating release managers improve a project's velocity and stability?

  - by Yannis Rizos

  The Wikipedia article on Parrot VM includes this unreferenced claim: Core committers take turns producing releases in a revolving schedule, where no single committer is responsible for multiple releases in a row. This practice has improved the project's velocity and stability. Parrot's Release Manager role documentation doesn't offer any further insight into the process, and I couldn't find any reference for the claim. My first thoughts were that rotating release managers seems like a good idea, sharing the responsibility between as many people as possible, and having a certain degree of polyphony in releases. Is it, though? Rotating release managers has been proposed for Launchpad, and there were some interesting counterarguments: Release management is something that requires a good understanding of all parts of the code and the authority to make calls under pressure if issues come up during the release itself The less change we can have to the release process the better from an operational perspective Don't really want an engineer to have to learn all this stuff on the job as well as have other things to take care of (regular development responsibilities) Any change of timezones of the releases would need to be approved with the SAs and: I think this would be a great idea (mainly because of my lust for power), but I also think that there should be some way making sure that a release manager doesn't get overwhelmed if something disastrous happens during release week, maybe by have a deputy release manager at the same time (maybe just falling back to Francis or Kiko would be sufficient). The practice doesn't appear to be very common, and the counterarguments seem reasonalbe and convincing. I'm quite confused on how it would improve a project's velocity and stability, is there something I'm missing, or is this just a bad edit on the Wikipedia article? Worth noting that the top voted answer in the related "Is rotating the lead developer a good or bad idea?" question boldly notes: Don't rotate.

• New "delay" keyword for JavaScript

  - by Van Coding

  I had a great idea for a new javascript keyword "delay", but I don't know what I can do to bring it to the new specification. Also I want to know what you guys think about it and if it's even realistic. What does the delay keyword ? The delay keyword does nothing more than stop the execution of the current stack and immediately continues to the next "job" in the queue. But that's not all! Instead of discarding the stack, it adds it to the end of the queue. After all "jobs" before it are done, the stack continues to execute. What is it good for? delay could help make blocking code non-blocking while it still looks like synchronous code. A short example: setTimeout(function(){ console.log("two"); },0); console.log("one"); delay; //since there is currently another task in the queue, do this task first before continuing console.log("three"); //Outputs: one, two, three This simple keyword would allow us to create a synchronous-looking code wich is asynchronous behind the scenes. Using node.js modules, for example, would no longer be impossible to use in the browser without trickery. There would be so many possibilites with such a keyword! Is this pattern useful? What can I do to bring this into the new ECMAscript specification? Note: I asked this previously on Stack Overflow, where it was closed.

• web browsing vs. torrent traffic, and bandwidth priority?

  - by suli8

  recently i did download big torrent files. (120 Gb). and i need to seed them back to at least 1.5 ratio. my upload speed is 130 Kb/s max. the problem is that i need to seed them as fast as possible. but i browse the web a lot. and browsing with no upload left, can be very frustrating. I'm looking for something like this, torrent are on max. seeding rate, but when the browser needs the bandwidth, it gets it. priority is to web browser, but when not needed, torrent can be at max. i'm aware that i can change torrent client max speed. but doing it manually everytime and every 5 minutes or so, is hard. Info: i'm using firefox/chrome my torrent client is Ktorrent i'm on 11.10 with unity i do have a router, it's a HAG. and i can't access all it's properties. is this possible even? changing the priority in the system monitor for the applications can do the job?the nice value i mean. is there a way to set priority bandwidth usage for different apps? thank you!

• How to make and restore incremental snapshots of hard disk

  - by brunopereira81

  I use Virtual Box a lot for distro / applications testing purposes. One of the features I simply love about it is virtual machines snapshots, its saves a state of a virtual machine and is able to restore it to its former glory if something you did went wrong without any problems and without consuming your all hard disk space. On my live systems I know how to create a 1:1 image of the file system but all the solutions I'v known will create a new image of the complete file system. Are there any programs / file systems that are capable of taking a snapshot of a current file system, save it on another location but instead of making a complete new image it creates incremental backups? To easy describe what I want, it should be as dd images of a file system, but instead of only a full backup it would also create incremental. I am not looking for clonezilla, etc. It should run within the system itself with no (or almost none) intervention from the user, but contain all the data of the file systems. I am also not looking for a duplicity backup your all system excluding some folders script + dd to save your mbr. I can do that myself, looking for extra finesse. I'm looking for something I can do before doing massive changes to a system and then if something when wrong or I burned my hard disk after spilling coffee on it I can just boot from a liveCD and restore a working snapshot to a hard disk. It does not need to be daily, it doesn't even need a schedule. Just run once in a while and let it its job and preferably RAW based not file copy based.
