• Compact DIY Office-in-a-Cart Packs Away Into a Closet

  - by Jason Fitzpatrick

  Many geeks know the pain of losing a home office when a new baby comes along, but not many of them go to such lengths to miniaturize their offices like this. With a little ingenuity an entire home office now fits inside a heavily modified IKEA work table. Ian, an IKEAHacker reader and Los Angeles area geek, explains the motivation for the build: I had to surrender my home office to make room for my new baby boy ;) I took an Ikea stainless steel kitchen “work table”, some Ikea computer tower desk trays, two steel tabletops, and two grated steel shelves to make an “office” that I could pack away into a closet. Hit up the link below to check out the full photo set, the build includes quite a few clever design choices like mounted monitors, a ventilation system, and more.

• HTG Explains: Why Do Hard Drives Show the Wrong Capacity in Windows?

  - by Chris Hoffman

  If you’ve ever purchased a computer with a hard disk capacity of 500 GB and opened Windows Explorer only to find that its capacity looked more like 440 GB, you may be wondering where all those gigabytes went. There are several reasons Windows could display the wrong amount of available space, from invisible shadow files, formatting overhead, and hidden recovery partitions to misleading (though technically accurate) storage capacities advertised by hard drive manufacturers.

• Making profit from a social network

  - by James P.

  This follows similar questions but I'd like to see if anything particular comes out of it due to the nature of site. In short, I've taken up the role of webmaster for a small social network site and wish to make it profitable to at least cover the running costs. The site is linked to a commerce and presents are offered to members according to the number of points they've accumulated through various actions. The site is running on shared hosting so it's probably dirt cheap but the presents can be expensive as a whole and some money has already been invested into the project. One idea I have is to seek some sponsors that would be willing to offer presents or special offers in return for publicity. I don't know if this will be easy or not. I'm also looking into adapting hosting to perhaps move static files to a cheaper online storage medium (see Ideas for reducing storage needs and/or costs (lots of images)). Other suggestions are welcome.

• Big Data – Buzz Words: What is HDFS – Day 8 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned what is MapReduce. In this article we will take a quick look at one of the four most important buzz words which goes around Big Data – HDFS. What is HDFS ? HDFS stands for Hadoop Distributed File System and it is a primary storage system used by Hadoop. It provides high performance access to data across Hadoop clusters. It is usually deployed on low-cost commodity hardware. In commodity hardware deployment server failures are very common. Due to the same reason HDFS is built to have high fault tolerance. The data transfer rate between compute nodes in HDFS is very high, which leads to reduced risk of failure. HDFS creates smaller pieces of the big data and distributes it on different nodes. It also copies each smaller piece to multiple times on different nodes. Hence when any node with the data crashes the system is automatically able to use the data from a different node and continue the process. This is the key feature of the HDFS system. Architecture of HDFS The architecture of the HDFS is master/slave architecture. An HDFS cluster always consists of single NameNode. This single NameNode is a master server and it manages the file system as well regulates access to various files. In additional to NameNode there are multiple DataNodes. There is always one DataNode for each data server. In HDFS a big file is split into one or more blocks and those blocks are stored in a set of DataNodes. The primary task of the NameNode is to open, close or rename files and directory and regulate access to the file system, whereas the primary task of the DataNode is read and write to the file systems. DataNode is also responsible for the creation, deletion or replication of the data based on the instruction from NameNode. In reality, NameNode and DataNode are software designed to run on commodity machine build in Java language. Visual Representation of HDFS Architecture Let us understand how HDFS works with the help of the diagram. Client APP or HDFS Client connects to NameSpace as well as DataNode. Client App access to the DataNode is regulated by NameSpace Node. NameSpace Node allows Client App to connect to the DataNode based by allowing the connection to the DataNode directly. A big data file is divided into multiple data blocks (let us assume that those data chunks are A,B,C and D. Client App will later on write data blocks directly to the DataNode. Client App does not have to directly write to all the node. It just has to write to any one of the node and NameNode will decide on which other DataNode it will have to replicate the data. In our example Client App directly writes to DataNode 1 and detained 3. However, data chunks are automatically replicated to other nodes. All the information like in which DataNode which data block is placed is written back to NameNode. High Availability During Disaster Now as multiple DataNode have same data blocks in the case of any DataNode which faces the disaster, the entire process will continue as other DataNode will assume the role to serve the specific data block which was on the failed node. This system provides very high tolerance to disaster and provides high availability. If you notice there is only single NameNode in our architecture. If that node fails our entire Hadoop Application will stop performing as it is a single node where we store all the metadata. As this node is very critical, it is usually replicated on another clustered as well as on another data rack. Though, that replicated node is not operational in architecture, it has all the necessary data to perform the task of the NameNode in the case of the NameNode fails. The entire Hadoop architecture is built to function smoothly even there are node failures or hardware malfunction. It is built on the simple concept that data is so big it is impossible to have come up with a single piece of the hardware which can manage it properly. We need lots of commodity (cheap) hardware to manage our big data and hardware failure is part of the commodity servers. To reduce the impact of hardware failure Hadoop architecture is built to overcome the limitation of the non-functioning hardware. Tomorrow In tomorrow’s blog post we will discuss the importance of the relational database in Big Data.

• Default file permissions for php user www-data

  - by John Isaacks

  I have a php installed on my ubuntu machine. The web root is /var/www I set the permissions for this folder like so: sudo chown -R ftpuser:www-data /var/www ftpuser is the user I set up so I can ftp to /var/www from another machine on the network. www-data is the user php uses. I double checked using whoami from php. Whenever I ftp upload a new file to the machine the group has no permissions to the file. So when I try to access it in my browser via machine-name/new-file.php I am told permission denied and I have to go and chmod the new file. I am wondering if there is a way I can default the www-data user/group to have access permissions to new files so I don't have to keep chmod every new file?

• How do you put a database online?

  - by Dezrik

  I have a very beginner question regarding web development. I've had some experience with JSP, Hibernate, and MAMP to create a simple system for tracking inventory and sales. But this was all done locally on one computer. This time, I want to create a system that could be accessible online. It's to help my mother track her business wherever she goes. So there would be similar aspects like tracking inventory and sales. I understand that you have to have a server in which to host all the files in. But I don't understand how you can access your database online. Or what sorts of applications or products should be used. Currently the host of my database is localhost. How do put it online such that you can still do CRUD operations? Are there any guides to do this?

• CD/DVD drive not mounted when inserted with Disc of any kind

  - by Cisco Sán

  I just noticed that if a insert a CD or a DVD of any kind, the Drive will start spinning but it will not show the mounted disc. Before it used to ask me what to do with the media inserted. Now it doesn't even do that. I ran in the terminal this code: eject -n and it displays this: " eject: device is `/dev/sr0'" what can I do to get the functionality back on my drive. also ran this command: sudo mount -o ro,unhide,uid=1000 /dev/cdrom /mnt/cdrom but in return i get this: " mount: mount point /mnt/cdrom does not exist" Running Ubuntu 11.10 HERE IS THE HISTORY UNTIL NOW thanks Waltinator: I ran the 'dmesg' but don't know what I'm looking for. Im a newbie on this. The same thing with the 'ls -rlt /var/log' command.

• Building a distributed system on Amazon Web Services

  - by Songo

  Would simply using AWS to build an application make this application a distributed system? For example if someone uses RDS for the database server, EC2 for the application itself and S3 for hosting user uploaded media, does that make it a distributed system? If not, then what should it be called and what is this application lacking for it to be distributed? Update Here is my take on the application to clarify my approach to building the system: The application I'm building is a social game for Facebook. I developed the application locally on a LAMP stack using Symfony2. For production I used an a single EC2 Micro instance for hosting the app itself, RDS for hosting my database, S3 for the user uploaded files and CloudFront for hosting static content. I know this may sound like a naive approach, so don't be shy to express your ideas.

• Why doesn't Wolfram Workbench work on 64-bit Ubuntu?

  - by Ian Hincks

  I have downloaded the shell script (Workbench_2.0.0_LINUX.sh), I have run it as root with it giving no complaints, relevant looking files have appeared in /usr/local/Wolfram/WolframWorkbench/2.0/ and it has created the executable "WolframWorkbench" in /usr/local/bin. However, when I run WolframWorkbench from terminal it spits out /usr/local/bin/WolframWorkbench: 46: exec: /usr/local/Wolfram/WolframWorkbench/2.0/WolframWorkbench: not found That file does indeed exist, and is executable. I have also tried running it directly, and I have also tried running the /usr/local/Wolfram/WolframWorkbench/2.0/Executables/WolframWorkbench too. Is there something I'm missing? (I am running Ubuntu 12.04 64bit with openjdk7)

• Good text editor for Ruby on Rails programming?

  - by Andrew

  I'm trying to find a text editor that I can use for doing Ruby on Rails development. I have been using TextMate on my Mac and would love to find something that even comes close to that experience. My Ubuntu laptop is a little old, and doesn't have a lot of memory, so I need something lightweight. I don't need/want a bloated IDE because the performance on my slow laptop would be terrible. It would be nice if this text editor had: Syntax highlighting A project/file browser view to be able to open files in my project Keyboard shortcuts (don't need them as much)

• Looking for a light weight note program.

  - by Erin

  This might belongs on superuser but for me it's part of programming so i will ask it here. I find I use notepad to keep chunks of data that are important but not important enough to keep in my head. The one problem with this is I end up with a lot of files on my desktop that I don't know what they are for, or I don't save the file and my computer gets rebooted for some reason. So that big ramble leads to the question. I am looking for a note taking system that is light weight and easy to manage. I would rather it not be a huge application like onenote but if that is what you are using and is is working well for you could you explain how you are doing it? Thanks Erin.

• How to move MOSS 2007 to another SharePoint Farm

  - by DipeshBhanani

  It was time of my first onsite client assignment on SharePoint. Client had one server production environment. They wanted to upgrade the topology with completely new SharePoint Farm of three servers. So, the task was to move whole MOSS 2007 stuff to the new server environment without impacting data. The last three words “… without impacting data…” were actually putting pressure on my head. Moreover SSP was required to move because additional information has been added for users apart from AD import.   I thought I had to do only backup and restore. It appeared pretty easy at first thought. Just because of these three damn scary words, I thought to check out on internet for guidance related to this scenario. I couldn’t get anything except general guidance of moving server on Microsoft TechNet site. I promised myself for starting blogs with this post if I would be successful in this task. Well, I took long time to write this but finally made it. I hope it will be useful to all guys looking for SharePoint server movement.   Before beginning restoration, make sure that, there is no difference in versions of SharePoint at source and destination server. Also check whether the state of SharePoint Installation at the time of backup and restore is same or not. (E.g. SharePoint related service packs and patches if any)   The main tasks of the server movement are as follow:   1.        Backup all the databases 2.        Install and configure SharePoint on new environment 3.        Deploy all solutions (WSP Files) globally to destination server- for installing features attached to the solutions 4.        Install all the custom features 5.        Deploy/Copy custom pages/files which are added to the “12Hive” folder later 6.        Restore SSP 7.        Restore My Site 8.        Restore other web application   Tasks 3 to 5 are for making sure that we have configured the environment well enough for the web application to be restored successfully. The main and complex task was restoring SSP. I have started restoring SSP through Central Admin. After a while, the restoration status was updated to “unsuccessful”. “Damn it, what went wrong?” I thought looking at the error detail down the page. I couldn’t remember the error message but I had corrected and restored it again.   Actually once you fail restoring SSP, until and unless you don’t clean all related stuff well, your restoration will be failed again and again. I wanted to find the actual reason. So cleaned, restored, cleaned, restored… I had tried almost 5-6 times and finally, I succeeded. I had realized how pleasant it is, to see the word “Successful” on the screen. Without wasting your much time to read, let me write all the detailed steps of restoring SSP:   1.        Delete the SSP through following STSADM command. stsadm -o deletessp -title <SSP name> -deletedatabases -force e.g.: stsadm -o deletessp -title SharedServices1 -deletedatabases –force 2.        Check and delete the web application associated with SSP if it exists. 3.        Remove Link from Check and remove “Alternate Access Mapping” associated with SSP if it exists. 4.        Check and delete IIS site as well as application pool associated with SSP if it exists. 5.        Stop following services: ·         Office SharePoint Server Search ·         Windows SharePoint Services Search ·         Windows SharePoint Services Help Search   6.        Delete all the databases associated/related to SSP from SQL Server. 7.        Reset IIS. 8.        Start again following services: ·         Office SharePoint Server Search ·         Windows SharePoint Services Search ·         Windows SharePoint Services Help Search   9.        Restore the new SSP.   After the SSP restoration, all other stuffs had completed very smoothly without any more issues. I did few modifications to sites for change of server name and finally, the new environment was ready.

• Performance Tuning with Traces

  - by Tara Kizer

  This past Saturday, I presented "Performance Tuning with Traces" at SQL Saturday #47 in Phoenix, Arizona.  You can download my slide deck and supporting files here. This is the same presentation that I did in September at SQL Saturday #55 in San Diego, however I focused less on my custom server-side trace tool and more on the steps that I take to troubleshoot a production performance problem which often includes server-side tracing.  If any of my blog readers attended the presentation, I'd love to hear your feedback.  I'm specifically interested in hearing constructive criticism.  Speaking in front of people is not something that comes naturally to me.  I plan on presenting in the future, so feedback on how I can do a better job would be very helpful.  My number one problem is I talk too fast!

• How do I get the source code from a Google Code game project?

  - by BluFire

  I'm trying to get the Hedgewars source code. When I went to the downloads tab, it doesn't specify which is the actual game. I tried downloading it using the SVN Checkout on Tortoise, but it seems like it doesn't work on the browse section of Source. (Hgproject_filesAndroid_buildSDL-android-project) I then proceeded to the wiki but I got stuck at step two because I don't know anything about Mercurial. Some other things I don't know from the wiki is "FreePascal" "Android NDK" and "Tar" files. They are new to me so I am really confused. So my question is, how can I download the source code from Hedge Wars for Android without having to browse the source code inside the source tab?

• Is there a Windows philosophy of programming?

  - by Maglob

  I've been programming both in Unix and Windows environments. Mostly I've worked in Unix, where I've learned Unix Philosophy, which can be summarized as Write programs that do one thing and do it well. Write programs to work together. Write programs to handle text streams, because that is a universal interface. There seems to be a clear difference in programming cultures between Unix and Windows worlds, for example: GUI vs CLI Registry vs config files Lots of tools specializing for any given need vs group of generic orthogonal tools which can combined Is there equivalent of "Unix philosophy" in Windows world? What Unix-programmer can learn from Windows or should be aware of when moving to programming in Windows? I would like answers to focus on the best practices of Windows programming (and not a fight between Windows and Unix).

  Hi, Today I have been unable to boot into my Ubuntu (10.10) or Windows (7) partition. Ubuntu kernel panics on boot with the error: init: hash.c:296: Assertion failed in nih_hash_search: hash != NULL I can boot into a LiveUSB environment, and from there can access all my files on my 3 partitions (1 ext4, 2 NTFS). I have also ran fsck on the ext4 partition and ntfsfix on the 2 NTFS partitions, both not finding any errors at all. And Grub is intact and have also tried a reinstall of it. So at the moment I'm currently stuck using a LiveUSB, and would like to see if there are any other options other than reinstalling. Thanks. Update I've now ran chkdsk using my Windows recovery disk, and it found errors and fixed them, but I am still unable to boot into either Windows or Ubuntu Update #2 I've decided to just re-install Ubuntu and start again as I didn't really want to spend any more time looking around whilst I need this computer for work. Thanks for all your help though.

• What is the ideal self hosted search engine?

  - by Tim Post

  I have an internal (intranet) site that is comprised of several blogs and forums, hundreds of static pages, lots of PDF files and several other document types. Its been glued together loosely over the last couple of years and now its my job to maintain it. I'm looking for a search engine that I can host myself that ideally: Allows for searching the Blog / Forum databases directly if given the database information and tables to search. Handles most text documents (PDF/DOC/ODF) Is open source, or allows access to the source code once purchased It doesn't matter to me what language or platform it is written in. Normally, I'd just use Google site search, but that's not an option for an intranet.
