• Serverlocation move and how can I Move the files

  - by Bernhard

  Hello together, I´ve a big problem. I have to move data from an old Webspace which is only accessibla by ftp. No we have a new root server which is accessible by ssh of course :-) No i Need to move all data from the old space but there is a lot of Gb of files. Is there a way to fetch all files directly from the old ftp to the storage and not over a third station (my local machine)? I´ve tried it with ftp but without success. I think I´ve used the wrong commands. Is there a way to etablish something like this including all files and directorys? Thank you in advance Bernhard

• Where should SQL/DB Queries be encapsulated in a software system?

  - by Stephen Bennet

  I frequently write small applications (either web based or otherwise) that require heavy database usage. i've attempted various ways of handling where to put the actual sql queries (sort of ad-hoc ORM systems). These include: Models that build themselves up - and only allowing SQL to be inside of a model. A sort of factory style method where the models are built by a factory class that is allowed to know about SQL. A third entity that maps models based on their fields/keys into the database and generates SQL code on the fly based on this. Is there a common knowledge of which method is best? Or another way I have missed? Clearly a lot of it will be based on the context of the system itself, which for me is usually to produce lightweight tools or utility frameworks. In experimenting, I've never found any of them that feel intuitively "right" and not clunky, but I also do not want to go for a full framework such as Django or Ruby - both because the tools I create are in a variety of languages and because they usually do not warrant that level of surrounding footprint.

• Needs free/ opensource network monitoring tool for office LAN

  - by Amit Ranjan

  I know there must be a lot similar questions on SU. Let me explain my setup first. I have 4-5 PC, Laptops and Few Android Phones in my office. To get them on a network , I have a UTStarCom, WA3002G1 ADSL2+ router with a landline broadband connection which has nothing to do with any PC except the configuration settings. Broadband channel is always on, we need to switch on the router and the internet is ready for us. No Internet Connection sharing is done via any PC. I have a limited 20GB monthly plan, which is consumed in 10-20 days, depending upon the download requirements. So in the above case, i need some suggestions from you: How do I monitor my Internet Bandwidth along-with the connected systems, realtime? Any free opensource tool available? Tweaks / Changes in PC to save bandwidth as my ISP do not have any Unlimited plan. PC and Laptops are Windows XP and/Or windows 7. Either of the platform tools are welcome.

• Introducing Programming To a Mathematician

  - by ell

  I currently am a programmer, I'm almost 16 years of age and have pretty much narrowed my careers down to something involving a Computer Science degree or Electrical Engineering degree (I know they are quite different but this question is about my friend) but my friend isn't so sure. He is very interested in maths and is very good at it and I think he would enjoy programming but he isn't willing to try it (edit he is willing to try but has never done before). Can anyone give me an suggestions for a language or tool that he could dabble in programming (at a reasonably basic level I assume) to solve maths problems or involve some kind of maths. As I say he enjoys maths a lot but I think he would enjoy programming, the problem is I don't want him to be put off by the stuff that isn't relevant at introductory levels such as memory allocation et al. I know that is very important but the point is that I want him to learn a bit of programming with maths then hopefully if he is interested enough he can start learning programming as programming. Thanks in advance, ell. Edit: Its not that he's completely uninterested - more that he hasn't actively explored the area before, maybe because he isn't informed about it. I wouldn't want to force him to do something he doesn't want to, I see this as more of a little push so that he can learn about programming. If he doesn't like it - fair enough, I can't control that and don't want to but if he turns out to enjoy it - this push will have been the right thing.

• Importing video from a videotape recorded on Soy Handycam

  - by Akhil Langer

  I used Windows Movie Maker to import videos from a videotape recorded on Sony handycam. I imported the video in .avi format( as it was giving the best video quality), but the size of the video is very large (8GB for just 1 hour). Moreover, it takes a lot of time to import the video in Windows Movie Maker (approx. 2.5 hrs. for 1 hour video). Please suggest some other software which is more robust in the sense that it can give good quality video in lesser size and also it should be able to import the video quickly(as I have to import many video cassettes).

• Is comparing an OO compiler to a SQL compiler/optimizer valid?

  - by Brad

  I'm now doing a lot of SQL development at my new job where as before I was doing Object Oriented desktop app stuff. I keep running across very large scripts (thousands of lines) and wanting to refactor in some way. I am seeing that SQL is a different sort of beast and it's probably fine to have these big scripts for the most part but while explaining this to me people are also insisting that the whole idea of refactoring is bad. That stuff like the .NET compiler are actually burdened by refactored code and that a big wall of code is more efficient and better design than code designed for reuse, readability and scalability. The other argument is that OO compilers are almost dangerously inefficient and don't have efficient memory management or runs too many CPU instructions compared to older "simpler" compilers and compared to SQL. Are these valid complaints? Even if some compiler like a C compiler is modestly more "efficient" (whatever that means on this high of a level without seeing code) would you want to write applications in C over C# or Java? Is comparing an OO compiler to a SQL compiler/optimizer even valid?

• Empirical evidence for choice of programming paradigm to address a problem

  - by Graham Lee

  The C2 wiki has a discussion of Empirical Evidence for Object-Oriented Programming that basically concludes there is none beyond appeal to authority. This was last edited in 2008. Discussion here seems to bear this out: questions on whether OO is outdated, when functional programming is a bad choice and the advantages and disadvantages of AOP are all answered with contributors' opinions without reliance on evidence. Of course, opinions of established and reputed practitioners are welcome and valuable things to have, but they're more plausible when they're consistent with experimental data. Does this evidence exist? Is evidence-based software engineering a thing? Specifically, if I have a particular problem P that I want to solve by writing software, does there exist a body of knowledge, studies and research that would let me see how the outcome of solving problems like P has depended on the choice of programming paradigm? I know that which paradigm comes out as "the right answer" can depend on what metrics a particular study pays attention to, on what conditions the study holds constant or varies, and doubtless on other factors too. That doesn't affect my desire to find this information and critically appraise it. It becomes clear that some people think I'm looking for a "turn the crank" solution - some sausage machine into which I put information about my problem and out of which comes a word like "functional" or "structured". This is not my intention. What I'm looking for is research into how - with a lot of caveats and assumptions that I'm not going into here but good literature on the matter would - certain properties of software vary depending on the problem and the choice of paradigm. In other words: some people say "OO gives better flexibility" or "functional programs have fewer bugs" - (part of) what I'm asking for is the evidence of this. The rest is asking for evidence against this, or the assumptions under which these statements are true, or evidence showing that these considerations aren't important. There are plenty of opinions on why one paradigm is better than another; is there anything objective behind any of these?

• Drawbacks of installing linux on usb stick?

  - by Znarkus

  I am setting up a router/nas/http/whatever server based on an ION mini-ITX board. I've installed Ubuntu Server on an old 160 GB drive, but it generates a lot more heat and vibrates more than my other new drive (storage). It just doesn't fit the concept, and worse: it takes up a SATA port. As SSD's are crazy expensive I'm thinking of buying an extra 4 GB USB stick, and raid0 it. From my point of view, these are the pros/cons: Pros Low power consumption No vibrations No heat Smaller Get to buy new, larger USB stick (:D) Cons Shorter life time Slower Raid 0 More work maintaing/installing? I think the pros overweighs the cons. Shorter life time and raid 0 is countered by regular backups of the configs/settings. Slower is partially countered by raid 0, and I don't know about the last one. What do You think? Experience? Another solution?

• USB to USB CD ROM emulator

  - by JohnnyLambada

  I'm wondering if anyone knows of a CDROM emulator that runs on Linux. I want to emulate this configuration: [CDROM DRIVE]----USB CABLE----[COMPUTER UNDER TEST] Where [COMPUTER UNDER TEST] is a computer that boots from a physical CD inserted into the [CDROM DRIVE]. Only instead of the [CDROM DRIVE] I want the following configuration: [CD IMAGE BUILD MACHINE]-----USB CABLE-----[COMPUTER UNDER TEST]. I want to build an ISO image on the [CD IMAGE BUILD MACHINE] and have some sort of USB CDROM emulator running on it to serve up the ISO image to the [COMPUTER UNDER TEST] as though it was talking to the [CDROM DRIVE]. Does this exist? If it does, I can't find it. I want to do this so I can test out bootable CDs without burning a lot of coasters.

• The Case of the Invisible Training Resource

  - by GGBlogger

  I’ve been at this programming business longer than I would like to admit. For that reason I am always looking for new training resources as anyone in this business knows all too well. I’ve looked at AppDev (way too expensive for my meager budget), LearnVisualStudio (I have a lifetime subscription), and several others. What appears to be a new version of AppDev called LearnDevNow has some good material and so it goes. So what does all this have to do with the title? I’ve been using Adobe’s Flex Builder 3 and now their latest Flash Builder 4 (a renaming of the Adobe Flex development environment). One of the offered perks on registering was a month’s subscription to Lynda.com. My first reaction was “What the heck is Lynda.com?” but I chose it and signed up. What a surprise I was in for. I’d never heard of them before but discovered one of the most comprehensive training resources I’ve ever seen – and all for $ 34.95 a month in the version that offers Exercise files. They do have a heavy focus on Adobe products but also cover a lot of Microsoft material. What bothered me is that in the time I’ve been in this business I’d never heard of them! ; Thus the allusion to “The Invisible Training Resource.” Not only do they offer beginner and in depth training but the syllabus and the instructors are some of the best I’ve seen in the industry. So I just feel that more folks need to know about this organization. If you need training in the venues they offer I can attest to the fact that they offer some of the best training available in this industry in my humble opinion. You really owe it to yourself to check out Lynda.com.

• Error when restarting computer after successful Ubuntu 12.10 installation

  - by Amy

  I was having a lot of sudden issues with my computer (slow on start up progressing quickly to not being able to start ...even in safe mode). Worked on several different things. Finally tried formatting hd and then installing Windows 7. Got errors so I said screw it and tried Ubuntu. Downloaded it (via my laptop), burned on DVD, and tried a disc boot on my desktop. Went through the whole installation, said it was successful and progressed to the restart. It stopped at a screen with an error (0x1b5a6) from 'hd0' I don't remember the error code verbatim. Now when I try restarting it I get to the initial page, hit 'enter' on Ubuntu..and it just sits at a blank screen. Eventually it runs through this screen with a bunch of code and then just sits there. I can't type anything and enter does nothing. Some things on the screen are: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0) I don't know what else to do... Restarting does not work. I have been working on fixing my computer for almost 2 days straight...

• dual boot preinstalled windows 8 laptop with windows 7

  - by sarathi

  I am having a hard disk in gpt partition style and Windows 8 is pre-installed in uefi mode. While trying to dual boot using usb bootable disk(using rufus,gpt partition style,fat32),it displays "Windows is loading files", then while displaying "Starting Windows" it hangs. So, I tried to install it inside Windows using setup.exe. Everything was running fine, but when it gets self restarted again, it got stuck at "Starting Windows". When restarted in Windows 8, it showed a htm file stating that "Windows cannot be installed on a computer using battery power. If the battery runs out of power during the installation, you might lose data. To continue the installation, plug in the computer's power adapter." I am sure that power adapter is connected. I Googled a lot on this, but I didn't get solution.

• Roadmap for Thinktecture IdentityServer

  - by Your DisplayName here!

  I got asked today if I could publish a roadmap for thinktecture IdentityServer (idrsv in short). Well – I got a lot of feedback after B1 and one of the biggest points here was the data access layer. So I made two changes: I moved to configuration database access code to EF 4.1 code first. That makes it much easier to change the underlying database. So it is now just a matter of changing the connection string to use real SQL Server instead of SQL Compact. Important when you plan to do scale out. I included the ASP.NET Universal Providers in the download. This adds official support for SQL Azure, SQL Server and SQL Compact for the membership, roles and profile features. Unfortunately the Universal Provider use a different schema than the original ASP.NET providers (that sucks btw!) – so I made them optional. If you want to use them go to web.config and uncomment the new provider. Then there are some other small changes: The relying party registration entries now have added fields to add extra data that you want to couple with the RP. One use case could be to give the UI a hint how the login experience should look like per RP. This allows to have a different look and feel for different relying parties. I also included a small helper API that you can use to retrieve the RP record based on the incoming WS-Federation query string. WS-Federation single sign out is now conforming to the spec. I made certificate based endpoint identities for SSL endpoints optional. This caused some problems with configuration and versioning of existing clients. I hope I can release the RC in the next days. If there are no major issues, there will be RTM very soon!

• What is good book for administration & configuration of Storage logical arrays?

  - by unknown (yahoo)

  I am looking for a book which can explain pros and cons of different combination of configurations/policies of storage Arrays and may also suggest some best practices for certain scenarios for e.g. when data availability & security is very important. There are a lot of "books for dummy" but they don't go in depth, I am a more of developer so I would like to understand how and why exactly it works beneath policies & configuration settings. I am working with EMC clarion logical array but I will have to work with EMC Symmetrix or NetApp or any other types of disk arrays.

• How to create an "hybrid" usb stick?

  - by rdesign

  Hey guys, I was wondering how to make an hybrid usb stick. That means a usb stick that runs under mac and windows and displays specific content. Example: Plug in on win : index.html opens. Mac os X files are invisible. Plug in on mac: indexMac.html opens. Win files are invisible. I know that every usb stick can be read by both platforms. The Apple Mac os X CD is something which inspired me. thanks a lot.

• Learning C, C++ and C#

  - by Zac

  I'm sure you guys are tired of this question but after wading through hours of similar posts and questions I've really not made any progress to my specific concerns. I was hoping you guys could shed some light on a couple of questions I have before I decide on a course of action. BACKGROUND: I'm wanting to enroll in some type of program to learn a programming language/get a certificate/degree to work in the field. I've always been interested and bought a book on VB back in high school and dabbled. Now I want to get serious after a huge hiatus. Question 1: I've read it's counter-productive to learn C first, then C++ or C# because you develop bad habits. In a lot of college courses I've looked at, learning C/C++ is mandatory to advance. Should I ever bother learning C? On a related note, I really don't understand the difference between C and C++, or C# for the matter other than it incorporates .NET (which, I understand, is a compilation of tools and libraries that make programming easier and faster). Question 2: Where did you guys learn to program? Where do you recommend? Is it possible to land a job programming being self-taught? Is my best chance an ITT tech or a regular college? I was going to enroll in a JC and go from there but I can't decide what to do. LAST question :) I heard C++ is being "ported" to .NET. True? And if so, is this going to make C++ a solid, in-demand language to learn? Thanks for looking. :)

• How to access web server of any machine of my network from the outside

  - by Luc

  Hello, I have an ip like username.dyndns.org, this is the external IP of my router. On my lan, I have several machine (m1, m2, ...) , each running a dedicated web server. Is it possible to reach each machine from the outside with something like: http://m1.username.dyndns.org http://m2.username.dyndns.org ? Do you know what needs to be configured in my router for NAT ? Also, is there a special directive in Apache to do so ? Thanks a lot, Regards, Luc

• Programs minimized for long time takes long time to "wake up"

  - by bart

  I'm working in Photoshop CS6 and multiple browsers a lot. I'm not using them all at once, so sometimes some applications are minimized to taskbar for hours or days. The problem is, when I try to maximize them from the taskbar - it sometimes takes longer than starting them! Especially Photoshop feels really weird for many seconds after finally showing up, it's slow, unresponsive and even sometimes totally freezes for minute or two. It's not a hardware problem as it's been like that since always on all on my PCs. Would I also notice it after upgrading my HDD to SDD and adding RAM (my main PC holds 4 GB currently)? Could guys with powerful pcs / macs tell me - does it also happen to you? I guess OSes somehow "focus" on active software and move all the resources away from the ones that run, but are not used. Is it possible to somehow set RAM / CPU / HDD priorities or something, for let's say, Photoshop, so it won't slow down after long period of inactivity?

• Pidgin: a me-specific log file?

  - by Wolfpack'08

  I'm trying to make a compilation file of all the text sent by me and all the responses that included my name.... What's the best way about scripting this? Is there a plugin like that for pidgin? I'd also like to be able to click on lines to add. For example, someone gives a really useful, easy-to-follow guide to another user, and I think: "I'm going to be doing that tomorrow." Rather than marking and pasting every line of it and skipping through all the other convo, I would like to be able to just click 'send to my personal log,' or something. It seems quite useful, right? And I think that a lot of people would use it. So, please try to provide a comprehensive answer, if possible, or one that I can follow through on.

• parameters in a seo url

  - by Marius

  This should be a very simple question for seo experts. Let's say we have the following URLs: http://www.test.com/some-sort-of-page http://www.test.com/some-sort-of-page?pgid1189 http://www.test.com/some-sort-of-page/page/1189 http://www.test.com/page/1189/some-sort-of-page The first one is an ideal solution. What i need to do is to somehow pass a resource identifier in the url to know exactly what this url is pointing to, since it can be pointing to a lot of different things. In the second URL, "pgid" specifies that the resource is a "page". URLs 3 and 4 specify the same thing differently. I do not care if the URL is friendly to people, because, let's face it - 99.9% of people will never ever ever bother to remember such url no matter how "friendly" it is. So the question is: which of the last 3 URLs would be the best solution for search engines? My guess is it would be the 2nd with query string, but i might be wrong. Thanks for your thoughts P.S. please don't offer using the first url. There's no problem using it, but the question is not about that.

• Chat client/server that offers certain options.

  - by MrStatic

  A few friends of mine and including me for the past few years have hosted an irc server on one of our dedicated servers. We use it for just personal reasons. We like the aspect of it that it allows private messages and chat rooms. Plus the ability to send/receive files and is cross platform (Linux/Mac/Windows/Mobile). Our domain is about to expire and we are looking to move onto something new. So we are looking for a chat client / server that offers the following: Chatroom (multiple people chatting together in the same box) File transfers Private messages Cross Platform (especially mobile ie: Blackberry and Android) We don't have to host it but that isn't out of the question Logging on the client side (we say a lot of crap and like to go back and quote said crap) SSL/TLS Some sort of encryption some of the stuff said/sent is of a sensitive nature ie: business nature

• Ubuntu server very slow out of the blue sky (Rails, passenger, nginx)

  - by snitko

  I run Ubuntu server 8.04 on Linode with multiple Rails apps under Passenger + nginx. Today I've noticed it takes quite a lot of time to load a page (5-10 secs). And it's not only websites, ssh seems to be affected too. Having no clue why this may be happening, I started to check different things. I checked how the log files are rotated, I checked if there's enough free disk space and memory. I also checked IO rate, here's the output: $ iostat avg-cpu: %user %nice %system %iowait %steal %idle 0.17 0.00 0.02 0.57 0.16 99.07 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn xvda 2.25 39.50 16.08 147042 59856 xvdb 0.00 0.05 0.00 192 0 xvdc 2.20 25.93 24.93 96530 92808 xvdd 0.01 0.12 0.00 434 16 xvde 0.04 0.23 0.35 858 1304 xvdf 0.37 0.31 4.12 1162 15352 Rebooting didn't help either.

• Level Creating Help

  - by Brandon oubiub

  I am making a little 2d overhead RPG type game just for fun. I have almost all the basic stuff set up, but I just need a little help on level creation. I can already make a level and place each tile how I want it, but having to place each tile gets annoying after a while. I noticed that in a lot of games, even extremely simple ones, they have LOTS of levels with LOTS of tiles in each. Creating all that in this fashion would take forever. So I guess my question is, as a game developer, am I supposed to do all that, or maybe make a little level editor so I can see things as I create it? What do game developers do? I'm using Java. EDIT: Okay, say if I had an image for a map, that I made in MS paint or photoshop, and each pixel represent a tile value, could I somehow in Java detect what color an individual pixel is? If so, that would be perfect. If so, how?
