  • Star Trail Photos Taken from the International Space Station

    - by Jason Fitzpatrick
    While most people have seen a star trail photo or two, seeing a set of star trail photos taken from over 300 miles above the Earth’s surface is a treat. Courtesy of Astronaut and Expedition 31 Flight Engineer Don Pettit, the photos capture star trails from the vantage point of the International Space Station. He explains his technique: My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then ‘stack’ them using imaging software, thus producing the longer exposure.

  • PXE booting on old computer

    - by kosciak
    So my computer is not working - the disk is totally cleared, I've deleted GRUB and PLOP which I used to install new system, because CD-Rom is broken and BIOS is old (whole computer is old, it's Sony Vaio PCG-GR250) so it won't allow me to do it via USB and I got no floppy drive :) the only way is to PXE boot PLOP and install Linux from USB after PLOP has been opened. (I'm not a specialist but that's how I see it) I'm using Mac OS X 10.9 and I followed number of tutorials how to set up TFTP and DHCP server and I got PLOP here, but when I boot up with PXE it says that it found DHCP but TFTP timed out. Any help or alternative way of rescuing old laptop? Thanks in advance!

  • Dual Boot Installation with Win7 - Install Ubuntu in New Partition

    - by RC Russell
    Under Win 7 I created a new 100 GB disk partition (L:) to install Ubuntu 12.04. I then rebooted from the Ubuntu install CD, selected "Install side by side" and now I'm stuck. I end up at the Advanced Partitioning Tool and I do not know how to tell the installer to use the L: partition. Any help would be appreciated. Thanks! Thank you. I have successfully installed Ubuntu 12.04 alongside Win 7. However, now when I reboot the laptop it goes directly to Win 7 with no option to choose Ubuntu. Any thoughts on how to get the boot-time choice to show up? Thanks!

    I had created a demo web application by executing rails tickets and then i executed rails script/server to run it on localhost. Initially i was able to execute the application in the browser by typing localhost:3000 in the address bar, but then I deleted the folder tickets from my hard disk. Now again i created the same folder but when i try to run it using the same command rails script/server it says that vverma@l-vverma:~/railsExp/tickets$ rails script/server create File exists - script/server I tried deleting the script/server file but i still couldn't run the localhost:3000 in the browser Tried rails s as well, it gave the following output:- http://paste.ubuntu.com/1317610/ But still i was unable to run the app on 'localhost:3000' What is the solution to this

  • New install preserving home directory

    - by john francis lee
    I have 32bit 11.10 installed on an LVM disk taking up all 500gb, and I would like to install 64bit 12.04 on top ... preserving the data in my home directory. I used to do that pre-LVM by just not formatting the partition mounted as /home, installing over / and /usr and formatting /tmp ... but now I don't recognize the partition table. I've never had much luck with 'upograde' and so I just install afresh when I want t new version. Surely I can do what I want, can't I?

  • Nautilus is really slow

    - by david
    Nautilus used to be lightning fast.Now it's dead slow. I have tried upgrading the video card but that does not seem to be the problem. Also I found that there was a problem with the Dropbox uninstall, finally I replace it with pcmanfm which appears to be much faster but the down side is that I no longer have the gwibber social client and a lot of stuff don't work like they use to. Also I completely removed nautilus and couldn't even login to ubuntu to install again nautilus.How can I remove or repair nautilus, and use pcmanfm instead? I have a dell inspiron 1440 3gb ram / disk 300gb / Additionally, why does nautilus run fast when I run it as root? There are no USB devices attached to my computer. Thanks in advance

  • Expensive HDMI Cables Make No Difference

    - by Jason Fitzpatrick
    While we’re no strangers to spreading the news that expensive HDMI cables are a ripoff, we’re happy to share yet another study that shows there’s zero difference between a $5 cable and a $95 one. Over at the British hardware review site Expert Reviews, they subjected a wide selection of HDMI cables to extensive tests in a bid to produce the end-all examination of whether or not a premium HDMI cable could actually produce a better signal. They used capture cards, pixel-by-pixel comparison of output, and other techniques to pick over individual frames until they ultimately reached the same conclusion everyone outside of the Monster sales staff had already reached: you’re getting absolutely no benefit to spending $100 on cable that can be had for under five bucks.

  • How to import .m3u playlist

    - by Charl le Roux
    I exported my my iTunes playlists to .m3u files before I got rid of Win7 completely. Now I would like to import the playlists into Rhythmbox, but can't. My playlists contain windows filenames (e.g. D:\music....) instead of linux filenames (e.g. /mnt/music....). The music is still stored on the exact same disk and folder as it was under windows. I need a script to convert the file names, can anyone help?

  • virtualbox host | Ubuntu vs XP

    - by iambriansreed
    In order to lengthen the lifespan of my machine I am replacing the weakest link, the hard drive and installing a new OS. I had planned on using xp pro as my virtualbox host and ubuntu as guest. After messing with ubuntu desktop and server I am really impressed and am thinking of reversing the virtualbox setup; ubuntu host xp guest. I would use XP for Adobe Fireworks, Netflix, and iTunes (maybe) that's pretty much it. Any reason not to do ubuntu host with xp guest? I know the xp vbox will run slower as a guest but really how much slower? It's a desktop. 4gb ram, 500gb disk, Pent D 3.2 ghz

  • Solaris 11 Live CD alapú telepítés

    - by AndrasF
    Az elozo részben megigért két telepítési eljárás helyett kénytelen vagyok ebben a bejegyzésben kizárólag a Live CD-s változattal foglalkozni. Korábban nem gondoltam, hogy ennek bemutatása is több, mint 50 képernyo kimenetet igényel, ezért változtatnom kellett a korábbi tervezeten. A Solaris 11 Live CD-s telepítés elsosorban az asztali (desktop) felhasználók igényeit veszi figyelembe és kizárólag x86-os architektúrájú gépeken támogatott (annak ellenére, hogy SPARC-os rendszerek is rendelkeznek grafikus kártyával - pl. T4-1).A folyamat két részre bontható: eloször a vendéggép kerül kialakítása VirtualBox környezetben, majd ezt követi a Solaris 11-es telepítése virtuális gépre. HCL és segédprogramok (DDT, DDU) Mielott telepíteni szeretnénk a Solaris operációs rendszert, célszeru tájékozódni fizikai rendszerünk támogatottságáról. Erre jól használható a már említett hardver kompatibilitási (HCL) lista, vagy az alábbi két segédprogram: Device Detection Tool Device Driver Utility Mindkét alkalmazás képes rendszerünk hardver komponenseit feltérképezni és ellenorizni azok meghajtóprogram (driver) ellátottságát. Eltérés köztük abban nyilvánul meg, hogy míg a DDT futtatásához Java szükséges, addig a DDU Solarist igényel. Ez utóbbiról a telepítés során röviden szó fog esni. Telepíto készletek letöltési helye Hálózati installációtól eltekintve (*) telepítokészletre van szükségünk, mely az alábbi oldalról töltheto le. Célszeru letöltenünk mindhárom állományt és a csomagokat tartalmazó ún. repository médiát (a következo felsorolás utolsó eleme) is: sol-11-1111-live-x86.iso sol-11-1111-text-x86.iso sol-11-1111-ai-x86.iso sol-11-1111-repo-full.iso Az elso három változat indítható USB formátumban is rendelkezésre áll - ekkor iso végzodés helyett usb található a fájlnevek végén. Rövid utalást az egyes készletek feladatáról az elozo blog bejegyzés tartalmaz (link). Amennyiben SPARC architektúrájú rendszerre szeretnénk a telepítést végezni, 'x86' helyett a 'sparc' szöveget tartalmazó állományokra lesz szükség. (*) - arra is lehetoség van, hogy AI készletrol történo indítás segítségével végezzük a hálózaton keresztül történo telepítést. Ez akkor fontos, ha célgépünkön nincs PXE (Preboot Execution Environment) boot támogatás. VirtualBox konfigurálás Külön fizikai eszköz felhasználása nélkül virtuális környezetben is használható a Solaris 11, mint vendéggép. A VirtualBox használatával erre kényelmes lehetoség kínálkozik. Gazdagépünknek (Windows, Unix, Linux) megfelelo telepíto program, vagy programcsomag (jelenleg a 4.1.16-os verzió a legfrissebb változat) és az installációt is taglaló felhasználói kézikönyv letöltheto a termék oldaláról. A sikeres telepítést követoen az alábbi lépések során jutunk el az új virtuális gép kialakulásáig: 1. A VBox indítása után a központi ablak megmutatja a már létezo virtuális gépeinket (Sol11demo, Sol11u1b07, Sol11.1B16, Sun_ZFS_Storage_7000) és az aktuálisan kiválasztott egyed (Sol11demo) fobb jellemzoit (megnevezés, memória mérete, virtuális tároló eszközök listája...stb.) 2. A New gombra kattintva elindul a virtuális gépet létrehozó segéd (wizard) 3. Ezt követoen nevet kell adnunk a vendéggépnek és ki kell választanunk az operációs rendszer típusát (beszédes név használata esetén a VirtualBox képes az operációs rendszer családját kiválasztani, nekünk pusztán csak verziót kell beállítanunk): adjuk meg Solaris11-et névként és válasszuk a 64bites változatot (feltéve, hogy gazdagépünk támogatja ezt) 4. Telepítéshez és a kezdeti lépések megtételéhez 1536MB memória tökéletesen megfelel (ez késobb módosítható az elvárások függvényében) 5. Fizikai társaihoz hasonlóan, egyetlen virtuális gép sem létezhet merevlemez (jelen esetben virtuális diszk) nélkül. Használhatunk egy már létezo területet (virtuális lemezt tartalmazó állomány), de létrehozhatunk egy nekünk tetszo új példányt is. Maradjunk ez utóbbinál (Create new hard disk)! 6. A lehetséges formátumok közül - az egyszeruség okán - éljünk a felkínált alaptípussal (VDI - VirtualBox Disk Image). 7. Létrehozás során a virtuális lemez készülhet egyidejuleg (Fixed size), vagy több lépésben dinamikusan (Dynamically allocated). Az elso változat sokkal kevésbé terheli a rendszert, a második elonye pedig a helytakarékosság. Válasszuk a fix méretu változatot. 8. Most már csak egyetlen adat ismeretlen a VirtualBox számára, mégpedig a létrehozásra kerülo virtuális lemez nagysága. 8GB-os terület jelen esetben alkalmas az ismerkedés elkezdéséhez. 9. Amennyiben minden beállítást helyesen adtunk meg, a Create gomb megnyomása után elindul a virtuális lemez létrehozása. 10. Ez a muvelet a megadott adatoktól függoen néhány perc alatt befejezodik. 11. Hasonló megerosítés (Create gomb aktiválása) után elkezdodik a kért virtuális gép létrehozása is. 12. Sikeres végrehajtás után az új vitruális gép közvetlenül megjelenik a központi ablak baloldali listáján a rendelkezésre álló virtuális gépek közt. A blog bejegyzés folyamatosan frissül...a rész fennmaradó tartalma hamarosan felkerül az oldalra.

  • How are minimum system requirements determined?

    - by Michael McGowan
    We've all seen countless examples of software that ships with "minimum system requirements" like the following: Windows XP/Vista/7 1GB RAM 200 MB Storage How are these generally determined? Obviously sometimes there are specific constraints (if the program takes 200 MB on disk then that is a hard requirement). Aside from those situations, many times for things like RAM or processor it turns out that more/faster is better with no hard constraint. How are these determined? Do developers just make up numbers that seem reasonable? Does QA go through some rigorous process testing various requirements until they find the lowest settings with acceptable performance? My instinct says it should be the latter but is often the former in practice.

  • SQL Prompt Easter Egg

    - by Johnm
    Having Red Gate's SQL Prompt installed with SQL Server Management Studio has saved me many headaches over the years of its use. It is extremely nice to type in a table name and see not only the column names, but also their data types and identification of primary keys. Another cool feature is the built-in short cut scripts that are included toward the bottom of the suggestion box. An example of these short cut scripts would be to type in the letters  cv and then hit enter and the following template for CREATE VIEW will appear: CREATE VIEW --WITH ENCRYPTION, SCHEMABINDING, VIEW_METADATA AS     SELECT /* query specification */ -- WITH CHECK OPTION GO These scripts are great, and on occasion rather humorous. Recently, I was writing an UPDATE statement that would update a derived and aliased set of data in . An example of such a statement is as follows: UPDATE y SET a.[FieldA] = b.[FieldB] FROM     (         SELECT             a.[FieldA]             ,b.[FieldB]         FROM             [MyTableA] a             INNER JOIN [MyTableB] b                 ON a.[PKA] = b.[PKB]     ) y; Upon typing the UPDATE y portion I hit enter and the expression "A A A A R G H !" appeared resulting in an unexpected burst of laughter. With a dash of curiosity and a pinch of research I discovered that at the bottom of the SQL Prompt suggestion box resides a short cut script called "yell", which is described as "Vent your frustration". Another humorous short cut script is "neo", which is described as "-- I know Kung-Fu". All is required for these to activate is to type the first letter and hit enter. I wonder if there are any undocumented ones?

  • What is the best free program to burn DVD movies from DVD movie files that are present on the hard drive the way ImgBurn does it in Windows?

    - by cipricus
    Evaluating burning programs is difficult: it takes more time, while errors are very unpleasant. I have looked at AcetoneISO, Brasero, and K3B (which many recommend) but they seem more limited than Nero, CDBurnXP and especially ImgBurn from Windows. They all seem to work (did not tested them fully myself) but at a more basic level (create ISO, burn them, etc.). When it comes to something like creating a DVD movie disk from DVD movie files present on the hard drive, it seems to me that I would have to create the ISO first and then burn it, which involves using more hard drive space and more time. Looking in the Windows direction, there is a Nero for Linux. It costs money. ImgBurn is said to work well in Wine, but as yet I have not tested it enough. What other options are there?
