  • Cities from Space: A Tour of Urban Planning Patterns

    - by Jason Fitzpatrick
    While many cities developed haphazardly and organically with little structured planning, other cities were developed following strict organization–organization that reveals itself beautifully when seen from space. Wired magazine shares a roundup of ten well-planned cities viewed with a satellite’s eye. Among the roundup our favorite is the oldest, seen in the photo above: This nine-pointed fortress is perhaps the best example of a planned city from the Renaissance. Palmanova was built in 1593 and is located in the northeastern corner of Italy near the border with Slovenia. It was intended to be home to a completely self-reliant utopian community that could also defend itself against the Ottomans. It had three guarded entrances, ramparts between each of the star points and eventually a moat. Sadly, nobody was willing to move there. Eventually it was used as free housing for pardoned criminals. Today it is a national monument, a tourist destination and home to around 5,000 people. Hit up the link below to check out the other nine well-planned entries in the roundup.

  • FILESTREAM in SQL Server 2008 R2

    - by CatherineRussell
    Much data is unstructured, such as text documents, images, and videos. This unstructured data is often stored outside the database, separate from its structured data. This separation can cause data management complexities. Or, if the data is associated with structured storage, the file streaming capabilities and performance can be limited. FILESTREAM integrates the SQL Server Database Engine with an NTFS file system by storing varbinary(max) binary large object (BLOB) data as files on the file system. Transact-SQL statements can insert, update, query, search, and back up FILESTREAM data. Win32 file system interfaces provide streaming access to the data. FILESTREAM uses the NT system cache for caching file data. This helps reduce any effect that FILESTREAM data might have on Database Engine performance. The SQL Server buffer pool is not used; therefore, this memory is available for query processing. FILESTREAM data is not encrypted even when transparent data encryption is enabled.

  • M-Audio Delta starts up at wrong sample rate

    - by steevc
    When the PC starts my M-Audio Delta 66 is using 48000kHz sampling rate when it is set for 44100 in Envy24. This causes audio to play slower than it should. This is in Kubuntu 14.04 on my new PC using an AMD A8 6500 with 8GB. When I first installed it seemed okay, but at some point it went wrong and has been doing this consistently since then. Kernel is 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:31:42 UTC 2014 i686 athlon i686 GNU/Linux steve@slarti:~$ cat /proc/asound/card2/pcm0p/sub0/hw_params access: MMAP_INTERLEAVED format: S32_LE subformat: STD channels: 10 rate: 48000 (48000/1) period_size: 441 buffer_size: 3528 I can get it to switch to 44100 if I disable/enable the Delta in Pulseaudio volume control, but I have to do this every day and the sound still seems distorted. I can't see any issues in any of the config or log files I can find. If I boot the PC with a Mint Live USB it starts at 44100 and sound fine. Originally reported on Youtube is playing at the wrong speed - maybe soundcard related, but I'll close that and have this more relevant question instead.

  • Datenbank in a Box

    - by A&C Redaktion
    Die Oracle Database Appliance: ein zuverlässiges, einfach zu bedienendes und erschwingliches Datenbank-System. Endlich kommt ein Datenbanksystem auf den Markt, das auf die Bedürfnisse kleinerer Unternehmen zugeschnitten ist: Oracle Database Appliance (ODA). Nicht jeder, der große Datenmengen zu verwalten hat, kann schließlich gleich zu Exadata und Co. greifen. Die kompakte „Datenbank in a Box“ kombiniert Software, Server und Speicherkapazität und bietet diverse Vernetzungsmöglichkeiten. Sie beinhaltet zwei geclusterte SunFire-Server, die unter Oracle Linux laufen, vorinstalliert ist eine Oracle Database 11g Release 2. Einer der großen ODA-Vorteile: Die Datenbank wächst mit den Bedürfnissen des Unternehmens: Die Leistungsfähigkeit des Clusters lässt sich anpassen, indem per "Pay-as-you-grow" Software-Lizensierung sukzessive zwei bis 24 Cores freigeschaltet werden können. Sie bietet außerdem hohe Verfügbarkeit für Eigen- und Standard-OLTP sowie universelle Datenbanken, auch in großer Anzahl. Für den Schutz vor Server- und Speichersystemausfällen sorgen Oracle Real Application Clusters, beziehungsweise Oracle Automatic Storage Management. Proaktive Systemüberwachung, Software-Bereitstellung auf einen Klick, integrierte Patches über den gesamten Stack und ein automatischer Call-Home bei Hardware-Ausfällen sparen Kosten und Ressourcen bei der Instandhaltung. Über das Oracle PartnerNetzwerk steht Kunden eine große Anzahl an branchenübergreifenden und -spezifischen Anwendungen zur Verfügung, die von der besseren Verfügbarkeit der Oracle Database Appliance profitieren. Auch die Fachpresse setzt sich mit der neuen Oracle Database Appliance auseinander: Ausführlich berichten unter anderem die Computerwoche und heise online. Das Admin-Magazin bietet eine kurze aber treffende Übersicht. Eine ebenfalls anschauliche, etwas ausführlichere Darstellung bietet die Webseite von DOAG e.V. Im Webcast zur Oracle Database Appliance geht Judson Althoff unter anderem auf deren Bedeutung für das Partner-Business ein:

  • suggestions for lonewolf dev setup

    - by d33j
    I'm looking for some suggestions for a better development setup. Background: I'm a crusty old software engineer (mostly java of late) and I have around 50 - 100 incomplete java projects scattered everywhere, usb keys, HDDs, and spanning across 5 or 6 computers etc, which have been put on hold for a few years (ie: family). I have no version control at home. I've been using IntelliJ for around 10 years, so that's the only constant. I'm thinking of nominating one machine as a headless server to put all my projects on, maybe a ubuntu box, that way It won't matter which device I'm on, all my projects can be accessed (and I don't have to waste time actually looking for them). I don't need to access code over the net. These are my own 'happy place' projects so I only work on them when I'm at home, however I can see the benefit of the tasking app being online, that way if I think of something while on public transport lets say, I can add it then & there, but it's not a requirement. I can wait until I get home to create tasks. Summary: So I need some sort of version control so I can rollback mistakes, and some sort of simple tasking software where I can assign tasks for myself later on when I get time. I use Subversion, Sonar, Jira and Crucible at work but I think it's a little bit of an overkill for me though. What do you suggest?

  • how do I fix ati driver issue

    - by Michael
    I have little knowledge about ubuntu, but I am learning. Recently, my ubuntu 12.04 required that I update. I noticed that it was updating xorg and other things, after the update I was asked to reboot. I did. now when I start that computer up, it cannot detect any display and refuses to boot from usb. I have no idea how to recover my computer. It simply starts in what is akin to the terminal program and ask for my username and password. After that, I can enter commands. The problem may be because I manually installed drivers by copy pasting from some instructional that I now have no idea where they are, but what it amounts to is that I "built" the drivers. They were working GREAT until this update. I did this because otherwise I was unable to have sound through my hdmi. After I hand built the drivers, they worked great. After this update Ka-blam! nothing... Also, I had okay-ed lots of update sources (though all of them [xorg and such] were the stable versions, not the unstable update sources) Please help and thank you in advance. (if this is posted incorrectly or misplace, please let me know what to do)

  • Install Ubuntu on Asus Eee-PC 1005PE - Dealing with special partitions

    - by MestreLion
    I have an Asus EeePC 1005PE netbook and im planning on doing a massive re-partitioning (going to install Ubuntu, Mint, XP, etc) Ive noticed it has 2 "special" partitions: a 10Gb Fat32 RESTORE hidden partition (used by BIOS "F9 recovery" feature) and a 16Mb "unknown" partition at the end of the drive (used by BIOS "Boot Booster" feature). So, for both partitions, my question is: Can I move/resize the recovery partition freely? What are the requirements for it? (i mean, for it still be found by BIOS when i press F9/Activate BootBooster?). Partition table order? Partition type? Flags? Label? UUID? Can i make it a Logical (instead of primary) partition? Does it must be the flagged as boot? And, more importantly: where can i find any official documentation about it? Ive ready many (mis)information about it... some say Boot Booster partition must be last (in partition table), some say Recovery must be 2nd, that it must be bootable, etc. How can I know what is really needed for the BIOS to use both F9 and Boot Booster? Note: Im using gParted from a Live USB Stick (Mint 10 / Ubuntu 10.10), and ive noticed that, since the filesystem type of the Boot Booster is not recongnized, it cant move or resize it. Can I delete it and re-create it somewhere else? Whenever i create a 0xEF partition gParted crashes and quits and i cannot open it again (must delete the partition using fdisk / cfdisk)

  • Install Windows7 on drive with Ubuntu 12.04 already on. Is my plan good?

    - by John F
    I have Ubuntu 12.04 working fine, but need W7 occasionally. I just wanted to check that my plan for installing would work? Any help appreciated. Current partitions are: Partition....@ File System @ Mount Point @ Size.....@ Used.....@ Flags /dev/sda1....@ ext4........@ /ext4a......@ 37 GiB...@ 776 MiB..@ boot /dev/sda2....@ extended....@.............@ 122 GiB..@ -........@ ./dev/sda5...@ ext4........@ / ..........@ 37 GiB...@ 6 GiB....@ .unallocated @ unallocated @.............@ 7 GiB....@ - ...... @ ./dev/sda6 ..@ ext4........@ /home.......@ 77 GiB...@ 32 GiB...@ .unallocated @ unallocated @.............@ 65 GiB...@ - .......@ /dev/sda3...@ linux-swap..@.............@ 7 GiB....@ - .......@ My plan is to: - boot to ubuntu from USB ISO - change sda1 to NTFS - install W7 to sda1 - use the "Master Boot Record repair" utility to configure dual boot so I can see my original ubuntu installation as well as W7. Have I missed something? I'm concerned as to what the 776MB is that will be overwritten by the change to NTFS. It seems large for just the MBR? Would also appreciate it if anyone can explain what sda5 and 6 are being used for? Is sda5 Ubuntu and sda6 my data? Thanks in advance.

  • Network print to brother MFC-7420

    - by trampster
    I am trying to pint to a Brother MFC-7420 from my ubuntu 10.04 machine. The brother is attached to a windows XP machine and is shared. This is what I have tried: System-Administration-Printing, Add, Expand Network Printer, Windows Printer via SAMBA, Browse (I can find the printer no problems here), Foward, Choose Driver Dialog, Brother, My printer is not in this list So the next thing I tried was to download the printer driver from here http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_prn.html The driver installed fine but my printer still does not appear in the list. I also tried installing the cups wrapper but that gave the following error. Restarting Common Unix Printing System: cupsd [ OK ] cp: cannot stat `/usr/share/cups/model/MFC7420.ppd': No such file or directory dpkg: error processing cupswrappermfc7420 (--install): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: cupswrappermfc7420 I tried connecting the printer directly but even though I have installed the driver, when I go to printers and click on the printer (it shows up fine as a USB printer) then it say searching for drivers and then gives me a list, this is the same list as before which doesn't have my printer. It really shouldn't be this hard. on window you don't have to installing anything it just works and the same is true for my brothers Mac. How do I print to my printer?

  • Ubuntu on Samsung NP700Z5B - no Grub

    - by copolii
    I just bought a Samsung NP700Z5B laptop. Gorgeous machine and great performance! I do 2 things when I get a new laptop: Format the HD and install Winblows from a CD to ditch the bloatware Install some variant of Linux on it (lately Ubuntu) Step 1 worked fine (until earlier today), but I haven't been able to install Ubuntu on it for the past 3 days! I've tried Mint12, Ubuntu 12.04, Ubuntu 11.10, Ubuntu 11.04 and Ubuntu 10.04. The live CD and the installations all run fine and report no problems, but when I reboot grub is nowhere to be found! The system goes directly to Winblows! I've tried booting from the liveCD and re-installing grub via the chroot and purge & reinstall methods (https://help.ubuntu.com/community/Grub2) and neither makes a difference. I've also tried copying the boot sector: dd if=/dev/sda of=linux.bin bs=512 count=1 and putting it on c: then setting bcdedit to add the entry to the Windows bootloader with no results. Earlier today I decided to try and set my boot partition as an EFI boot partition ... bad choice, now I don't even have the Winblows boot loader. I've officially ran out of ideas. Tried calling Samsung, but they're closed (they'd probably say something stupid along the lines of "Samsung recommends Windows 7" ... I've had Dell say that to me). Any help would be greatly appreciated. Update 1 Tried re-installing 12.04 and now I get the screen continously turning off and back on, but still no sign of booting ... it has been doing it for 15 mins so far (I set the boot partition type to ext2 instead of ext4) Update 2 Well ... this just gets better and better. I inserted the installation USB key to reboot it and the flickering stopped for about a minute (remained on) then it started turning off and on again

  • How do I uninstall GRUB?

    - by ændrük
    A hard drive that I use only for data storage still has GRUB from past Ubuntu installations. How can I remove GRUB from it without harming the rest of the drive's data? Background I occasionally move the data drive between computers with various boot order configurations, so I would like it to be non-bootable in order to avoid having to accommodate it in each computer's BIOS settings. When I power on a computer while only the data drive is attached, the following appears: error: no such device: fdf38dd4-9e9d-479d-b830-2a6989958503. grub rescue> I can confirm from old backups of /etc/fstab that this was the UUID of a root partition that I recently reformatted and which no longer exists. Here's the the data drive's partition table and raw master boot record. Please note that I'm not interested in workarounds that don't answer my primary question. I can think of several ways to work around this issue, but it bothers me on principle that I don't know how to directly resolve it. Every installation procedure should have a counterpart uninstallation procedure.

  • How do I partition my Hard drive to install Kubuntu?

    - by Xdflames
    I am a complete newbie to partitioning and I would like some guidance here. Can anyone explain what exactly I should be doing here? I am installing Kubuntu 12.04 on a currently Windows 7 laptop. My current Partitions say this: /dev/sda /dev/sda1 ntfs 104 MB 35 MB /dev/sda2 ntfs 319965 MB 87164 MB Basically, what I want is some guidance on what exactly to do here. All I want is a partition for my OS (Which will be Kubuntu 12.04) and a partition for all of my data. I also want to restart fresh with my hard drive, with only what I mentioned on here. I am installing Kubuntu from a flash drive (I set it up as a bootable device with Universal-USB-Installer-1.9.0.9), as I do not have any blank CDs/DVDs to burn to. What should I name my partitions? What should I set the type as? What size do they need to be? Edit: My hard drive is 320GB. Just looked it up in my BIOS. This computer will mainly be used for internet browsing and overall just messing around with the Linux OS.

  • New SPC2 benchmark- The 7420 KILLS it !!!

    - by user12620172
    This is pretty sweet. The new SPC2 benchmark came out last week, and the 7420 not only came in 2nd of ALL speed scores, but came in #1 for price per MBPS. Check out this table. The 7420 score of 10,704 makes it really fast, but that's not the best part. The price one would have to pay in order to beat it is ridiculous. You can go see for yourself at http://www.storageperformance.org/results/benchmark_results_spc2The only system on the whole page that beats it was over twice the price per MBPS. Very sweet for Oracle. So let's see, the 7420 is the fastest per $. The 7420 is the cheapest per MBPS. The 7420 has incredible, built-in features, management services, analytics, and protocols. It's extremely stable and as a cluster has no single point of failure. It won the Storage Magazine award for best NAS system this year. So how long will it be before it's the number 1 NAS system in the market? What are the biggest hurdles still stopping the widespread adoption of the ZFSSA? From what I see, it's three things: 1. Administrator's comfort level with older legacy systems. 2. Politics 3. Past issues with Oracle Support.   I see all of these issues crop up regularly. Number 1 just takes time and education. Number 3 takes time with our new, better, and growing support team. many of them came from Oracle and there were growing pains when they went from a straight software-model to having to also support hardware. Number 2 is tricky, but it's the job of the sales teams to break through the internal politics and help their clients see the value in oracle hardware systems. Benchmarks like this will help.

  • Dual Booting Windows 7 and Ubuntu 12.04. Partition Sizes?

    - by John F.
    I'm about to reinstall Windows, so I thought that I'd try Ubuntu out on a partition just for fun. My question is, how large should my partitions be for each of them? I know this various depending on what you use, so i'll give you a general idea of what I have, and what I have in mind. I'm currently running: Windows 7 Professional (64bit) RAM: 4GB CPU: 2.5Ghz Quad Core processor HDD: 500GB GPU: 1GB Nvidia GeForce I have around 130GB in Steam games, and some heavier applications like Photoshop CS6, Sony Vegas Pro 11. But other Applications I use are: Chrome Skype Dxtory Fraps OpenOffice BitTorrent and other assorted smaller programs. So, I was thinking that I would give my Windows partition about 150-200GB, my Ubuntu Partition around 20GB, and the rest to shared storage. I'm not really sure if I'd need more or less on Ubuntu, because I've never used it and I'm not really sure what kind of apps i'd be using over there. This would also be a clean install, so I'd be wiping my HDD, creating the Partitions in GParted, then installing Windows with Ubuntu following that. Any critique you could give me? Maybe explanations to what the /root, /boot and /home partitions I hear are about? Thanks in advanced if you actually read this lengthy thing! Any help is appreciated. (x

  • How did we get saddled with the (hierarchical) filesystem as the basic data structure?

    - by user1936
    I'm self-taught and I don't have a CS degree. The more I've been learning about data structure, the more I wonder, in this day and age, how are we still saddled with the filesystem, with directories and files, as the basic data storage structure on the OS? I understand the simplicity of it, but it seems nowadays that there could be more options available natively. As far as I'm aware, the only project to improve the basic functionality of the filesystem was ReiserFS, where you could tell what line of a file was changed by whom, and when. For instance, if I could have native tagging for files, where I could tag images, diagrams, word-processing documents, an entire code repository, all as belonging to a single project, that would really be helpful to me. Since I'm stuck in the filesystem paradigm, I know that I could put all those into a single folder/directory, but what if they already exist in disparate directories, and they need to stay there? I know there are programs out there that can do this, but why aren't they on the filesystem? Something that would be nice to have is some kind of relational feature in the filesystem, like you get with RDBMSes. I understand that that was supposed to be part of Vista/7, but that fell off the feature list too. Sure, any program can store a binary file and have any data structure it wants in it, by why couldn't the OS offer more complex ways of storing data, beyond the simple heirarchy of the filesystem?

  • Amazon EC2 vs Dedicated server at Hetzner, what's the use for EC2?

    - by C-Blu
    After searching the web I still can't find the reason to use EC2. What's the point to scale EC2? If you expect a huge burst in traffic, they say. OK, but what if you already have a couple of sites with good traffic, and for example medium reserved EC2 instance is not enough. You are paying $36.60(medium reserved for 1year) in EU(Ireland) + traffic + optional expenses for databases and S3 if you use them. Of course as some point when you are under $56.6-$66.1 you can optimize your hosting costs with Amazon EC2. But when you get at some point if purchase EX4 server from Hetzner, it will surpass your perfomance needs for a long time, before you get a massive traffic. (I am wrong?) CPU: i7-2600 Quadcore (3.4-3.8 Ghz) RAM: 16 GB HDD: 2x3 TB SATA (6 Gbit/s) - I think that disc performance of a dedicated is better then of Amazon EBS Traffic: 10 TiB in month included. This is what you get from Hetzner for $56(- 19% VAT) or $66 for EU residents. Please, tell me what's the reason to use Amazon? Which load won't a server from Hetzner take, but Amazon Auto Scaling will? The maintenance of dedicated vs EC2 is still the same? Or hardware failure at Amazon, won't ruin your EBS storage? I'm still not at the level when I need expensive hosting, but want to know beforehand, just to be sure if Amazon infrastructure is better then pure performance of Hetzner's hardware.

  • Series On Embedded Development (Part 3) - Runtime Optionality

    - by Darryl Mocek
    What is runtime optionality? Runtime optionality means writing and packaging your code in such a way that all of the features are available at runtime, but aren't loaded and used if the feature isn't used. The code is separate, and you can even remove the code to save persistent storage if you know the feature will not be used. In native programming terms, it's splitting your application into separate shared libraries so you only have to load what you're using, which means it only impacts volatile memory when enabled at runtime. All the functionality is there, but if it's not used at runtime, it's not loaded. A good example of this in Java is JVMTI, Java's Virtual Machine Tool Interface. On smaller, embedded platforms, these libraries may not be there. If the libraries are not there, there's no effect on the runtime as long as you don't try to use the JVMTI features. There is a trade-off between size/performance and flexibility here. Putting code in separate libraries means loading that code will take longer and it will typically take up more persistent space. However, if the code is rarely used, you can save volatile memory by including it in a separate library. You can also use this method in Java by putting rarely-used code into one or more separate JAR's. Loading a JAR and parsing it takes CPU cycles and volatile memory. Putting all of your application's code into a single JAR means more processing for that JAR. Consider putting rarely-used code in a separate library/JAR.

  • Mobile development, recommended computer configuration?

    - by MikaelW
    Hi, For the last 4 weeks, I have been trying to get into mobile development. Done a couple of tutorials, read some books, developed a couple of dummy Android apps. The thing is my computer is a 5 years old laptop, it is slow and time has come to replace it and I’m looking at different offers online. Have you got any recommendations? Is there any must-have that should make my developer life easier in the future? Is there anything specific that may be useful at a more advanced stage of development that I just can’t think of right now on the hardware side? (I mean apart from good proc, lots of RAM, many USB ports...) One thing I can think of is to have three OS on the same workstation: Windows, Unix and MacOS (so far I focused on android/java/eclipse but am interested in Iphone/objC/xcode as well) but that’s more on the software side. Anyway, would be grateful for any recommendations. Thanks in advance! Mikael PS: I’m quite free on the budget side of things PPS: I'm aware it's not really a programming question but will still be of interest to some programmers here.

  • Touchpad and Keyboard both stop working after long uptime

    - by Sepero
    I have an Asus N53SM laptop that I leave running for several weeks at a time. I never put it in hibernate or suspend, I only close the lid when I'm not using it. After a few days or weeks of running, the touchpad and keyboard will Both lock up (at the same time) for no apparent reason. I could be just surfing the internet when it happens. The touchpad and keyboard seem to only lock up when I'm actively using the laptop (not when idle), which may mean it's related to something I press, but I'm not sure? The touchpad never locks or unlocks when Pressing FN and the designated touchpad lock key (it does not seem to work on Linux). While the touchpad and keyboard are locked, I am able to plug in my USB mouse and successfully use it to control the screen cursor. I can also remotely get into the system with vnc and ssh, everything seems to run fine there as well. No processes appear out of control. It's just the laptops physical touchpad and keyboard that are locking up. How might I go about diagnosing this problem? What system logs to look at? (anything specific to look for in them?) Perhaps I should try reloading some modules? Any thing else I should inspect?
