  • Alternatives to sql like databases

    - by user613326
    Well i was wondering these days computers usually have 2GB or 4GB memory I like to use some secure client server model, and well an sql database is likely candidate. On the other hand i only have about 8000 records, who will not frequently be read or written in total they would consume less then 16 Megabyte. And it made me wonder what would be good secure options in a windows environment to store the data work with it multi-client single server model, without using SQL or mysql Would for well such a small amount of data maybe other ideas better ? Because i like to keep maintenance as simple as possible (no administrators would need to know sql maintenance, as they dont know databases in my target environment) Maybe storing in xml files or.. something else. Just wonder how others would go if ease of administration is the main goal. Oh and it should be secure to, the client server data must be a bit secure (maybe NTLM files shares https or...etc)

  • How often do CPUs make calculation errors?

    - by veryfoolish
    In Dijkstra's Notes on Structured Programming he talks a lot about the provability of computer programs as abstract entities. As a corollary, he remarks how testing isn't enough. E.g., he points out the fact that it would be impossible to test a multiplication function f(x,y) = x*y for any large values of x and y across the entire ranges of x and y. My question concerns his misc. remarks on "lousy hardware". I know the essay was written in the 1970s when computer hardware was less reliable, but computers still aren't perfect, so they must make calculation mistakes sometimes. Does anybody know how often this happens or if there are any statistics on this?

  • Given two sets of DNA, what does it take to computationally "grow" that person from a fertilised egg and see what they become? [closed]

    - by Nicholas Hill
    My question is essentially entirely in the title, but let me add some points to prevent some "why on earth would you want to do that" sort of answers: This is more of a mind experiment than an attempt to implement real software. For fun. Don't worry about computational speed or the number of available memory bytes. Computers get faster and better all of the time. Imagine we have two data files: Mother.dna and Father.dna. What else would be required? (Bonus point for someone who tells me approx how many GB each file will be, and if the size of the files are exactly the same number of bytes for everyone alive on Earth!) There would ideally need to be a way to see what the egg becomes as it becomes a human adult. If you fancy, feel free to outline the design. I am initially thinking that there'd need to be some sort of volumetric voxel-based 3D environment for simulation purposes.

  • Learning programming

    - by user65862
    I am a senior & am a retired R.N., always good at math (50+ yrs ago, but still am). I have been in a computer users group since the mid 90's, & have become moderately advanced in using computers, including trouble-shooting other people's computer problems. Most of my expertise was gained by reading, asking questions, & trying my own trouble-shooting with the help of books & the internet. Now,I would like to take the next step and learn programming. What would be the best way for me to learn programming? Attending classes isn't a practical option, and I'm not in a position to spend much money. Any ideas would be greatly appreciated. Thank you. Margaret

  • Kernel won't update automatically

    - by Bucic
    My current kernel is 3.2.0-26 (my main computer) while on another of my Ubuntu computers, with which I didn't fiddle with unofficial updates, it's 3.2.0-30. Yet the Update manager on my main computer doesn't show available kernel updates. It shows other updates though. I suspect is due to the fact that in the past I installed multiple mainline kernel versions (not recommended versions), up to 3.5* series. What I'm after: Either: Fix automatic kernel updates. Or: Learn about a way to check for the latest official ubuntu kernel version and get it manually (I know how to install kernels from debs) What I have already tried: Uninstalled unused kernels including "the generic one without a number".

  • How do I install a driver for a Kodak esp 3250 printer?

    - by user108608
    First my system: pentium 4 -don't remember the speed-, 1g ram, dual boot to separate physical drives, Fdos and Lubuntu 12.1 second my lan: I have four computers operating for the same printer. Intel quad core i5, 4g ram, running Windoze 7 64 bit, printer connected and shared from here. Kodak ESP 3250 Gateway 17" laptop running Windoze 7 32bit Asus tablet (small laptop) running Lumbutu 12.1 My dual boot system running Fdos and Lubuntu 12.1 The problem: I downloaded c2esp_25c-1_i386.deb, tried to install it using DEBI Package Installer, it loads the files, looks for cups driver and ends with an error: "Dependancy is not satisfiable: libcupsdriver1 (=1.4.0)" What do I do now? Is there some place that I can get the correct cups driver? further information: The Asus tablet was running Ubuntu 12.1 (very slowly and with a few crashes) and could print from the lan printer with no problems. Is there something in Ubuntu that can be loaded into Lubuntu?

  • How can one get involved in the Ubuntu Brainstorm team?

    - by Jay
    I've heard it thrown around on a lot of blogs that Ubuntu Brainstorm is the "graveyard of good ideas". I have a bit of a passion for average end-users suggesting the kinds of software they want and they way they think their applications and computers could work. I'm interested in joining the Ubuntu Brainstorm team, maybe to facilitate ideas not getting buried and making it not seem like a dead platform. Unfortunately I'm not very plugged into the "community" so I'm not sure how to go about it. I was hoping someone might be able to point me in the right direction. Thanks.

  • Wubi doesn't install Ubuntu

    - by Nick
    I've tried 4 times on 2 different computers. After downloading wubi, and installing Ubuntu inside Windows XP, I restart and get the dual boot screen. I choose Ubuntu, and then nothing, my screen flashes for a few minutes with the Ubuntu colors. I restart and go to Ubuntu recovery, where it says "shadow passwords now on" and "clock off by a day-Fixed". I restart to only get the same thing, but Xubuntu, in stalled on one, but it's Ubuntu I want to try. Any thoughts ??

  • usb drive filesystem?

    - by purbleguy
    So, school is approaching quickly, and one of the things on my supply list is a usb drive. Now I'm asking myself what filesystem to use. After some research, I found ext4 to be the most stable drive filesystem. But, I also found that Windows (The OS used by every computer in my school) can't read ext4 formatted drives without special drivers, and I'm sure the school wouldn't be too happy with me having to install the windows ext4 drivers on every computer I use with my usb. So, my question is, Should I use fat32, one of the ext filesystems (2, 3 or 4 would work) or NTFS, I have an ubuntu laptop, a Mac desktop, and of course the school computers I use are Windows, so which would be the best filesystem for my usb.

  • Help with google pages; using them in general

    - by Sugarcube
    Is there any way someone could help me with building a website using google pages? I cannot for the life of me figure out how to do much more than create a new page, and I have been up all night. I thought I knew computers and websites but apparently I need a refresher course. Please, if you can help, I would be most appreciative. -Sugarcube Edit: Seems this is too vague. But honestly, I don't even know where to begin with the way Google has it set up. I tried to set one up with a template and a layout, but the layout has pages that I did not create and that I don't know how to edit to make them suitable to my website. I guess if I had to start somewhere it would be on how to make it do what I want it to do.

  • Domain mapping issues

    - by Nadya
    I have two domain names - .com & .co.uk bought with 123-reg and just one student Windows hosting pack associated with the .co.uk domain. The .com domain is the main one which people would be trying to access, so I just mapped the domain to the hosting this morning. The problem is that I would really like it to be functional by tomorrow morning and the usual waiting time is 24-48 hours. Is there point in stopping the process and trying with forward it with CNAME record instead, does it take less time? (I can just go back and do proper domain mapping during the weekend) Also, is there a possible way to check whether the domain mapping has been done correctly before these 24-48 hours? From some computers I get 404 Error on homepage.

  • Logout or shutdown shows terminal

    - by N.N.
    When I logout or shutdown the terminal (the one I reach with Ctrl Alt + F7) is sometimes shown before the login screen appears or before the computer is shut off. Is there a way to stop this behavior? More explicitly. If I logout the terminal is sometimes shown for a second before the login screen appears. Also, sometimes when I shutdown (from within Unity or Gnome) the terminal is shown, sometimes for the whole shutdown process or just for a second or two. I've had this problem throughout 10.04, 10.10 and 11.04 and I've always used the standard Ubuntu variant. I've also noticed this happening on a fresh install of Natty on a friends netbook, so it's not local to my computers.

  • Is there any guarantee about the graphical output of different GPUs in DirectX?

    - by cloudraven
    Let's say that I run the same game in two different computers with different GPUs. If for example they are both certified for DirectX 10. Is there a guarantee that the output for a given program (game) is going to be the same regardless the manufacturer or model of the GPU? I am assuming the configurable settings are exactly the same in both cases. I heard that it is not the case for DirectX 9 and older, but that it is true for DirectX 10. If someone could provide a source confirming or denying it, it would be great. Also what is the guarantee offered. Will the output be exactly the same or just perceptually the same to the human eye?

  • why does our network printer not show up on some of our macs, but does show up on others? [on hold]

    - by peter
    We lost power in our building and now cannot get our HP laser jet 5200 to be recognized by half of our computers. We are all Macs, some running OS 10.7.5 can see the printer, others running 10.7.5 cannot, and those running 10.8.5 and 10.9 cannot. We've re-booted the router, turned off and on printer and macs—no go. The printer displays an IP address (dynamically assigned) but we can't access it. Tried to see it using CUPS—same story, can see it on some systems, not on others. Any thoughts?

  • Learning to program on punchcards

    - by Plutor
    I'd like to try programming with punch cards once in my life. How can I do this? I'm in my 30s, and grew up entirely in the PC era, programming on computers with screens and keyboards. I want to experience the way my father and grandfather used to work. I imagine the hardware (and probably the cards themselves) are no longer manufactured. Are there any universities or museums with functioning punch card readers anymore? I'm in Boston, but I'm willing to travel to do this. I asked MetaFilter, and I got some mixed answers (along with a lot of "no, don't do this" nay-saying). I did get a pointer to the Retro-Computing Society Of Rhode Island, but I haven't received a response to my email to them yet.

  • Is there ongoing work in the kernel team to improve battery life under linux?

    - by leousa
    I have read in some forums that the kernel team is working on improving battery life and energy efficiency in linux. Unfortunately our community really lags behind windows and mac in that regard. I would like to read about the reasons why this difference exists with other platforms. Is it purely due to closed hardware specs from vendors or does it has to be with kernel design issues? Apple devices with unix cores have amazing battery times, but they also design their own hardware...just want to understand this issues in a less technical way I know that recent kernel updates in Ubuntu have improved the battery life in most computers, but I was wondering if there is still development going on and where can I read more about it. Thanks in advance

  • Can't install AMD drivers and Blinking problem

    - by demonscream
    I just installed Ubuntu 12.04 LTS with WUBI, everything is going fine and ubuntu is awesome but i have a little problem. When i open my Sony VAIO model E laptop, i have 2 choices (which is normal) but when i select Ubuntu 1/2 of the time it will just give a rapidly blinkin color background and can only be corrected if i reboot the computer and select ubuntu again. I think this has something to do with the fact i can't get any driver update for my computer from AMD, according to their website, VAIO computers aren't supported. I have a AMD RADEON HD 7650M graphic card which is not detected in ubuntu. When i try to install the drivers using the drivers application it gives a "can't install" error. What should i do?

  • Studying Quantum Computing?

    - by The_Neo
    Hi I am a computer science student currently on an internship and I have been thinking more and more about looking into working for a company / places that is developing quantum computers/ing when I graduate. Here is my problem, I have a pretty solid grasp of mathematics involved in Comp Sci and enjoy learning about more Comp Sci theory but in doing some minor research about Quantum Computing it seems to me to be more about hardware and I have always leant more to the software side of things. I haven't studied any physics since high school so I am wondering if I would be suitable to work in such a field with a Comp Sci degree, is it a field more aimed at physicists?

  • Server asks for username and password on boot

    - by Jon
    I installed the Ubuntu server 12.04 easily, however, when I boot it asks for a username and password. I don't know my previous username or password from Windows XP. I am currently trying to install any version of Ubuntu I have in my arsenal to recover the PC, but all intents so far have failed. They worked on other computers but not on this one, the error I get is No DEFAULT or UI configuration directive found! I have tried all the solutions found on this site but to no avail. I don't have a Windows Ultimate boot disk and I'm out of CDs to burn. I can, however, make live USBs. Any Suggestions?

  • ubuntu will not connect after restart

    - by nicedoggy
    Firstly, I hope this hasn't been covered elsewhere, I have searched but haven't found this particular problem. I updated to 12.04 a while back and though I now thoroughly regret that decision, I'm able to live with 12.04 and all it's odd little quirks. The one problem that I would like to fix is this. I have a small network, using a router modem which stays on most of the time. If the computer is switched off, when it is switched on again I have to click on "auto Ethernet" in "Network" in order to get on the internet. It then works fine. Previous versions just connected automatically on restart. When 12.04 says it is unable to connect, other computers on the network are able to connect. Thanks for any help.

  • How to make grub stop appearing every time I boot?

    - by Justin Riddiough
    I'm using Ubuntu 12.04 and grub selections appear each time I boot. This happens on both of my computers.

  • MinGw Multiple Definitions

    - by makuto
    I'm trying to get the MinGw C++ compiler set up so I can compile my code for Windows computers and I'm having troubles. I originally installed minGw32 but then found that mingw-w64 was a better fit for me, so I uninstalled minGw32 and installed mingw-w64. The problem is that when I try to compile a simple hello world application I get Multiple Definition errors (which are not from my code). I'm thinking it has something to do with the removal of w32 and the installation of w64 without a clean directory. How do/should I clean the necessary folders & get rid of those multiple definitions.

  • Is it correct to refer to a performing programming assignments as a "computer labs"?

    - by Nick Rosencrantz
    Can we say that developing an algorithm is a "laboration"? Are these "labs"? At engineering performing an exercise or an assignement is refered to as "labs" but are those "labs" when in fact it is mainly software problem solving pretty much like numeric methods in math which are not "labs". When studying engineering such as electrical engineering or physics you might do a "laser lab" or a "chemical laboration" if you study chemical engineering for instance. How do you define "lab"? Just performing something experimental? This is sort of double meaning also the physical environment at universities which we call "computer labs" that in fact are just rooms with computers.

  • Search for odt files without indexing

    - by josinalvo
    I am looking for: a way to search inside odt files (i.e. search for contents, not name) that does not require any kind of indexing that is graphical and very user-friendly (for a relatively old person, who does not like computers much) I know that it is possible to have 1) and 2): for x in `find . -iname '*odt'`; do odt2txt $x | grep Query; done works well enough, and it's pretty fast. But I wonder if there is already a good solution that does this with a GUI (or can be adapted to do this easily)

  • How to redirect visitors to the server that is closest to them and where to place the servers?

    - by user2971623
    I am focusing on providing fast page refreshes for my visitors and I wonder where is the smartest spot to place my servers on? I understand that the best would be to place a server in every country or even city, but that is of course not doable with my economy. I am thinking of maybe setting up three servers, one in the middle of USA (Kansas?), one in Italy and one in Sweden. What do you think about that? I don't care about Africa since they haven't even got computers so I won't get traffic from there anyway. China, North Korea etc are probably just visiting chinese websites, they barely know english anway... The next problem is how do I redirect a visitor from Finland to the Swedish server? I don't want the visitor from Finland to be using the USA server or vice versa.
