• Java or Python? Career/Start-up advice needed [closed]

  - by vim

  I have a full-time PHP job and I've been working with PHP for 5 years. As you can guess after spending 5 years I'm not willing to stay within this technology stack any more. I also worked with Java for 2 year before, so for me it looks more obvious to switch back to Java. However during last 5 years I was thinking about starting my own project, and now I think I have a very good SAAS idea. I'm completely confused what technology should I use for my project. I don't want to do it in PHP, and after reading many articles about rapid prototype development it seems to me that Django/Ruby is the best option. I will continue to work full time for my current employer because I need to pay my bills and will work on my project in my free time. The concern I have is should I do my project in Java or Python? To be realistic there is always a risk when you are doing your own project/start-up. If I do it in Java in the worst case scenario I believe I will be able to find a full time Java position because I already have some experience in Java + recent experience in my project. With regards to Python it looks like it is not very popular in my area and salaries are much more lower then for Java. On the other hand I have a feeling that if I chose Java it will take me a way longer to finish my project. Guys I'm completely confused and I need your advice. P.S. I have moved to London 2 years ago from another country, local guys are very welcome to share their thoughts about London's job market.

• XDMCP is slow any ideas? (looking for alternative remote desktops)

  - by peteri

  I've been used to using RDP on Windows to remote to machines, and I've got an asus eee 701 which I want to use to do some *nix programming on. While the eee is a lovely little machine the screen and keyboard are a little small to use for lots of programming. I've tried using Xming (the free version) to remote login into the eee from my desktop using XDMCP (or even using a ssh session as a straight X11 server and no desktop on the eee) the whole thing seems seriously slow over wifi the initial desktop takes at least 5 seconds to paint (might even be 10 seconds I haven't actually timed it). So my real question is what do other folks use for remote control with a GUI for their *nix boxes? I am finding it hard to believe the performance is so bad over a wifi network (It makes the Mac IIs I used to use a college in 1988 seem fast) or is this just a problem with Xming and using say the Cygwin X11 server would be better.

• What iPhone apps have I already purchased?

  - by torbengb

  I've bought many iPhone apps by now, some free and some paid. I've reinstalled my computer, and in the new installation, iTunes is completely blank. On first sync, iTunes downloads the apps that are currently installed on my iPhone. But what about all those apps that I have bought and aren't currently installed? Is there a way to re-download all my apps into iTunes? Where can I see a listing of all the apps I've ever downloaded? (Update: Apparently not all purchased content is restored - some things are inexplicably missing. You won't be charged anew for downloading them again, but you also won't be told what it is that you're missing. See here for details...)

• Hosing website on own server. What is Hardware requirement and Cost [closed]

  - by KuKu

  As i am about to finish my dream website, i need to host it on some server. I checked Amazon AWS Free Tier, i found it pretty complex. As i made full website in java(JSP + Servlet + mysql + Node.js), its been expensive to host. So i thought that why not to host on own server so that i will be fully dependent on my resources, not on any one else. And i know, in future i need to pay more and more to the other hosting company(because of uploading images and number of incoming users). So my question is, On initial stage what kind of hardware i will required. What can be the cost of that hardware? I already have 12MBPS broadband connection, will it be sufficient? It has static IP Address as well.

• A quick tip for those working with the Windows Phone 7 AD SDK.

  - by mbcrump

  One thing that I’ve noticed in several apps in the Windows Phone 7 marketplace is the ad chopping off on the right hand side. I decided that my next Windows Phone 7 app will be ad supported so why not sign up for the Advertising SDK and investigate this issue. *Note: If you want to see this in an actual app then download the free app called “Road Rage”. So here is an example of what I am talking about: You will notice that the right hand side of the AD is chopped off using the default ad banner. You can see the border on the left hand side clearly. So, what exactly is going on? Let’s take a look at this in the designer. From this image we can see it clearer, the margin of the grid that the ad is contained in needs to be removed. By default, the ContentPanel in a Windows Phone Page has a margin already set on it. See below for an example of this: <!--ContentPanel - place additional content here--> <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0"> </Grid> If you simply remove that margin then your ad will display properly as shown below. It’s strange that I’ve seen this in multiple WP7 applications in the marketplace. If you are trying to make money off Ads, you would probably want to make sure the full ad is displayed. I am hoping this short post helped someone.   Subscribe to my feed

• How does dropbox version/upload large files?

  - by barfoon

  Hey everyone, I have a free dropbox account (2GB), and I was wondering how the versioning of large files works. I have a full backup of all my webfiles that sites @ just over 1GB. After the initial upload of 1GB, everytime it syncs will dropbox figure out the delta of the file, or will it have to upload the entire thing again to version it? It would be cool to always have an up to date version of a large file, but I dont want to kill my bandwidth uploading 1GB everytime. Is this possible? Thanks,

• How to schedule download of windows 7 updates?

  - by atoMerz

  To put it short: I'd like to schedule my windows updates to start/stop at certain times of day. How can I do this? More explanation: This is because my internet traffic is limited by ISP and it's free only during a specific period throughout the day (2:00am-7:00am). I've set windows update setting to check for updates but notify me before downloading in order to prevent it from automatically using up my traffic. But then I have to manually tell it when to start downloading. I obviously don't want to stay up that late just to push a button. So again, how can I schedule windows updates to start/stop at specified times?

• Backup windows image to thumb drive?

  - by Dean

  I recently bought a new netbook from Malasia. It doesn't have a brand name, or officially supporting drivers. It came with a version of windows, and working drivers for all the hardware - but I want to install Ubuntu on here. Being a netbook, it has no CD/DVD drive. I want some free easy to use software to image the entire drive onto a thumb drive, which I could later use to boot up a recovery program to reinstall windows, should I fail to get all the hardware supported on Linux. I have already done some research and found driver backup/restore software in this thread, and will probably use that failing a more all-encompasing solution.

• Customer Reviews on Company Listings [closed]

  - by GSTAR

  I'm not sure if this is the right place but I am after some general advice on a feature I am looking to implement on my website. The website I have is a Wedding Directory. Here, companies can advertise in the form of a directory listing. This listing contains the company details - such as what they do and how you can contact them. There are three packages available - Basic package is free and Silver and Gold packages are charged for. Now in order to further enhance the directory, I want to enable customer reviews for each listing. This is basically whereby customers who have used a particular company's service can write a review (and rate out of 5) of their experience. The dilemma I face is that if customers are to be paying for their listings then surely they will expect to not have content on their listing that would tarnish their reputation (i.e. negative reviews). But at the same time I want to be impartial and help my site visitors to make informed choices on which companies to book when arranging their weddings. Of course I will exercise my ability to remove offensive or fake reviews but I do not want to be removing reviews just to satisfy my clients. Suppose a client pays me a premium fee to have their listing on my front page and at the top of the listings. Now suppose that client gets lost of negative reviews - the fact that they have increased visibility means that they will also get increased bad publicity. This in turn means they won't renew their package and will most likely request the listing to be taken down. So, how can I get the right balance here and keep everyone happy?

• Hard disk failure. Can I recover my "move"d folders?

  - by Doug

  I am in the process of moving all my files from an old laptop to new one. I just moved 11gb of data from my old laptop to a hard drive (external) and then upon moving it out to the new hard drive, the hard drive is getting a CRC (Data Error (Cyclic Redundancy Check). Now I am looking for a solution to recover the files that I moved on my old laptop (not the external). I understand they they are just marked for potential overwriting to free up space. I was getting ready to test out GetDataBack, but it says to install it on a healthy windows and use the recover-needed drive as an external. However, I don't want to turn off my computer without first getting the okay since it is in a "moved" state. Please help! What can I do to recover the Moved files. I haven't touched the computer since it has been moved. What can I use to recover them?

• How are software projects 'typically' managed/deployed

  - by rguilbault

  My company is evaluating adopting off-the-shelf ALM products to aid in our development lifecycle; we currently use our own homegrown solutions to manage requirements gathering, specification documentation, testing, etc. One of the issues I am having is that we have what we call a pipeline, which consists of particular stops: [Source] - [QC] - [Production] At the first stop, the developer works out a solution to some requested change and performs individual testing. When that process is complete (and peer review has been performed), our ALM system physically moves the affected programs from the [Source] runtime environment to the [QC] runtime environment. You can think of this as analogous to moving some web pages from the 'test' server to the 'live' server, where QC personnel can bang on the system and complain that the developer has it all wrong ;-) Once QC signs off that the changes are working, the system again moves the code along to the next stage, where additional testing is performed, etc. I have been searching the internet for a few days trying to find how the process is accomplished anywhere else -- I have read a bit about builds, automated testing, various ALM products, etc. but nowhere does any of this state how builds interact with initial change requests, what the triggers are, how dependencies are managed, how the various forms of testing are accommodated (e.g. unit testing, integration testing, regression testing), etc. Can anyone point me to any resources or attempt to explain (generically) how a change could/should be tracked and moved though the development lifecycle? I'd be very appreciative. To keep things consistent, let's say that we have a project called Calculator, which we want to add support for the basic trigonometric functions: sine, cosine and tangent. I'm open to reorganizing the company however we need to in order to accomplish due diligence testing and we can suppose that any tools are available for use (if that helps to illustrate the process). To start things off, I think I understand this much: we document the requirements, e.g.: support sine, cosine and tangent functions we create some type of change request/work order to assign to programming coding takes place, commits are made to version control peer review commences programmer marks the work order as completed? ... now what? How does QC do their thing? Would they perform testing before closing the 'work order'?

• Game programming : C# or C++?

  - by Chronix

  Ok so the faq says : "What language should I learn next? (Unless you have a specific requirement and don't know which language meets that requirement.)" so I guess this is not against the rules of questions. So, I've decided what I really want is to do Game Programming. So the question is, as a 18 years old who wants to learn self taught programming, what is the most suited programming language between C# and C++? ( I should state that I don't care about unix because I believe windows will be still the most used os ) I know the basics of C++, but none about C#. I know that C++ has more tutorials guides, dlls and stuff like that, while C# doesn't, but it's far easier to learn and to use for a single person to develop a program, but I've read even if the program is obfuscated it's easy to get the source of it. Well, I kinda want to focus on basic a lot first, I must say that I have a preference for C++ just because it feels more suitable to me, but I must consider that I work alone.. So even if I like it, it may not be the best thing to do. I am really not sure of which one to go for, i've read a lot of threads on various websites and it looks like C# is becoming more popular than C++. But yeah, that said, I also specified I want to do Game Programming. So I need to know some better points than just "C# is easier because of .net memory handling while C++ isnt" because I couldn't just find it. I hope the thread won't be closed because I've read the faq and I have a specific requirement. Thank you, and if you need more details you're free to ask me, but I think just by saying game programming and that I'd work alone should be enough!

• High system cpu load (%sys), system locks

  - by Mark

  For the last two weeks we are having intermittent severe spikes in system cpu usage (shown as %sys), which last for maybe half a minute, locking most processes, including ssh. I've been trying to figure this out, but atop doesn't show anything relevant (system usage for processes it shows is insignificant), spikes are intermittent and I could not reproduce the spike using any workload for the web application this webserver hosts. If you have any ideas on how to debug high %sys and (sometimes) %si CPU usage, please share them. System specs (don't know if any of this is relevant): Dedicated server, CentOS 6, core i7 950, consistent 4 to 8 GB RAM free at any time, hard drives are in RAID-1. Additional info: dmesg output doesn't change between spikes /var/log/messages doesn't change between spikes Here is cat /proc/vmstat Here is output of mpstat 1 during a typical spike Add 07.11.11: looks like simple reboot restored system state, and we might never know what caused the disturbance in first place.

• Remote desktop on Mac

  - by Crystal

  I just started a job using a Mac. I also have a Mac at home. The IT dpt here does not know how to remote login to my desktop from home. They installed the Cisco VPN client and game an account for that. I think at this point I need some remote desktop software to login to my work Machine. I looked online and downloaded the free version of TeamViewer. I didn't really understand how to use it. I have my work computer's name, and was hoping that would be enough to login, but I think I am mising a piece of the puzzle. Any thoughts on how to login to my work computer? Thanks.

• Value my C++ knowledge

  - by PirateOwh

  I have only followed antiRTFM tutorials and read 2 books So, I'll list the things I know better : basic input output and all the variables : integers ( signed unsigned ), float, double, char arrays if, for, while, switch functions, and passing variables to functions and return type thing classes and the concept of oop with separating declaration and definition in the header and in the source pointers so this and some more i think is all i know of C++.. But, i need some exercises to test my knowledge because i want to move on to the library SDL, so I don't know if i should feel ready or not to move on to something totally different.. I feel I should know the basics for good at least. So the question is : How can i value my c++ knowledge? Is there any online tests? Is there any GDD ( Game Design Document ) for free to use and see if i can manage to do it so "i'd pass" ? ( I'm saying GDD since ill move on to SDL and try to make my own game ) When should I move to SDL? What are ALL the things I should "master" ( master is a big word to say.. but so you understand what i mean ) before moving on ? Please I'm really in need of expert advice. I think my question is detailed so i hope you understand what i mean and can give me a good reply. Thanks for the help!

• What's a good box to serve files on my local network, cross platform?

  - by rogpeppe

  I've installed CAT5e cable and gigabit switches in my house with the goal of having an "always-on" file server in the loft, accessible to both my macbook and my partner's Windows box. I'd like to find a solution which: uses minimal power. allows me to access as much disk bandwidth as possible. provides glitch-free file access to both MacOS and Windows. is as cheap as possible, while remaining reliable. Optional, but desirable extras: software or hardware RAID; open source solutions. A SheevaPlug with eSATA seems one possibility, but I'm sure there are any number of other good options.

• Smart Phones Shockingly Energy Efficient; Lead to Decreased Household Power Consumption

  - by Jason Fitzpatrick

  Given how often our smart phones and tablets spend plugged in and topping off their battery reserves, it’s easy to assume they’re sucking down a lot of power. Analysis shows the lilliputian but powerful devices are surprisingly efficient and may be decreasing our overall power consumption. Courtesy of energy-centric blog Outlier, we’re treated to a look at the power sipping habits of popular smart phones and mobile devices. The simple take away? They use shockingly little electricity over the course of the year–you can charge your new iPhone for a year of regular usage for under a buck. The more complex analysis? The proliferation of tiny and energy efficient devices is displacing heavier energy consumers (large televisions, desktop computers, etc.) and driving a more efficient gadget-to-consumption ratio is many households.

• Mounting Solaris UFS partition on Debian(with FreeBSD kernel)

• Applying for job: how to showcase work done for (private) past clients?

  - by user33445566

  I want to apply for my first "real" (read: non-freelance) Ruby on Rails job. I've built several apps already. My best work (also the most logically complicated app) was for a freelance client, and I'd like to show it to potential employers. Only problem is: it isn't online anymore. And I've lost touch with the client. How can I include this work in my portfolio? About the app: It's a Facebook game. The client's business idea for this app was not the best. It was never going to make any money. I think it was kind of a vanity side project for him. The logo and graphics are nice-looking, though, and were designed by the client. I've actually spent a lot of time recently recoding most of the app, and adding a full test suite. I want to showcase the BDD / TDD skills I've acquired. I'm not very familiar with the etiquette (/law?) concerning this situation. Can I just put my new version of the app up at a free Heroku URL (perhaps with a "credits" section, where I credit the ideas and graphic designs to my former client)? NOTE: Again, this is just to show potential employers. I am not trying to market the app as my idea, or attract any users. Can I put some or all of the code on GitHub? What if I don't put the code up publicly, but merely send a tarball to potential employers? Do I need to ask permission from my former client (and what if he says no)? The last thing I want to do is get in any legal trouble, or offend people I'm trying get a job from. But I believe that my work and experience on this app are my highest recommendation for getting a job.

  I need to dump whatever is seen on the vim screen as it is, with colors and everything. Is there a way do to id. I am hoping that ncurses uses the same escape sequence for colors as bash. So when I'll do cat on the file that I've dumped the screen to, I should get the same output as the vim file. I want to use it in the scenario when I am doing a side by side colorful diff of files and need to print them. If anyone knows of any other side-by-side colorful diff programs, please feel free to mention in the comments (not answers because I am hoping that this question will be answered so that it can be used by others).

• VPS showing low disk space despite there is nothing major on it

  - by SheoNarayyan

  Hello experts, On my VPS server I was trying to see the used disk space and when I open My Computer it shows 17.9 GB free out of 39.8 GB it means that 21.9 GB space is used. However, when I select all files and folders from C: and try to see the total size, it just count approximately 11 GB. The difference is around 10 GB. Where is this 10 GB going if I have not stored anything else here? I asked above question from my VPS provider and he responded below Check hidden files/system files/etc. This is default windows OS and its utilization and not specific to setup. If you want specifics of usage, you can go ahead and get in touch with Microsoft support team and they'll provide you with exact specification of the same. I am sure that Windows OS must not be taking up 10 GB space for hidden files and folders. My VPS has Windows Server 2008 R2 installed. Can anyone help me in this on who is right?
