• Option do not show schema names in SQL Server Management Studio

  - by Jörgen Sigvardsson

  I love the fact that tree and list controls in Windows allows incremental searches. Just select a starting point, and type, and the control will select the best matching node for you. This works in SSMS, but there's an annoying problem, especially so in the table node. SSMS prefixes all table names with the schema name and a dot. To make an incremental search here, I have to type 'dbo.', followed by whatever I'm searching for. Is there an option to turn off this table name representation in SSMS? I hope I'm asking this on the right stack exchange site. If you feel it's off base, let me know!

• GAC and SharePoint

  - by Sahil Malik

  SharePoint 2010 Training: more information GAC and SharePoint have had a funny love & hate relationship. In 2007, SharePoint and GAC fell in love. GAC was about the only practical alternative to deploying custom code. Here is a dirty secret, based on completely unscientific and unfounded research, I can tell you that 99% of SharePoint code written, ended up in the GAC. Yes, I know GAC rhymes with hack, crack, smack, and even mac, but still it was the better alternative. You could write CAS policies and put your DLLs in the bin folder, but it was mighty inconvenient to both write, and maintain. Most of us never did it. There are still some SharePoint developers out there insisting on the bin approach – well, get over it; you’re not winning the fight. CAS is about as outdated as Samantha Fox anyway. It was hot at one point though. So all that code that ended up in the GAC caused lots and lots of headache. Clearly, Microsoft had to get us off the crack, uhh .. I mean the GAC.

• Is there a browser addon to redirect a link to another, modifying some address content automatically?

  - by kokbira

  Well, I'm looking for an addon that can redirect a link when I click on it in the following ways: Change from https to http Change from twitter.com/xxxxxxxxx to, for example, dabr.co.uk/xxxxxxxxx (added at 2010-02-15th, 20:30 GMT) Remove the "?utm_source=twitterfeed&utm_medium=twitter" from the end ou a URL Generally, replace a string with another (e.g. youtube->yt; so www.example.com/visitingyoutube would become www.example.com/visitingyt) PS: (added at 2010-02-15th, 20:30 GMT) @oKtosiTe, a clearer user case: Supposes that there is a link in Twitter that point to a URL X (URL X is http://www.newspapersite.com/2011-02-15_1304.html?utm_source=twitterfeed&utm_medium=twitter) In that case, I want to open that URL only until ".html", i.e., I want to open a URL Y, that is http://www.newspapersite.com/2011-02-15_1304.html What happens when I click normally in that link: 3.1. Browser goes to URL X What I want to happen when I click in that link: 4.1. The addon must transform URL X to URL Y (I must configure it before to change a piece of URL from "?utm_source=twitterfeed&utm_medium=twitter" to "" 4.2. The browser goes to URL Y

• Coda-like experience for Ubuntu

  - by Dillon Gilmore

  I'm a web developer who's going to transition from using Mac OS X to Ubuntu. I've been using Coda for some time, only because it makes web development easy. I know a full fledged app isn't available for Linux, but would like to know about apps that specialize in the same tasks that Coda offers. I plan on switching to Vim for code editing, I'm extremely proficient and will install the Janus plugin and be good to go for editing code. One thing that makes editing on Coda so amazing is its extremely good at SFTP, you can drag and drop files and/or folders from your local drive to the server. Also, you can edit code directly on the server. The problem here, is that using Vim I don't know of a way to edit code on a remote server, while using my own Vim settings and plugins. To solve this, I would like to know of a good SFTP client OR a good SFTP CLI. A CLI that could synchronize your files after a file has been modified would be perfect, but not necessary. Now, one of the biggest and best features of Coda is its ability to view your databases. You get to create a database, create tables, add stuff, delete stuff and view the contents of the table (all this without writing a single SQL statement). I will admit that databases are my weak point, but is a very important part of my job. If there is a tool that specializes in databases would be perfect. I wouldn't prefer to use the command line for database stuff, but if there is a CLI for databases that I'm missing could potentially be useful. So I guess I'm asking for two things. A tool that makes databases easier to visualize and a tool that assists in pushing my local code to a server.

• Hosting a site on amazon ec2

  - by Khalid Mushtaq

  I have recently bought an amazon ec2 instance. Now I want to host a website. I have googled and found some useful info but there is some confusion in my mind. Suppose domain name is "http://www.example.com" That's what I have done so far. I have configured my domain locally on amazon ec2 instance and it's working fine when I open that url in amazon ec2 instance's browser. I have used http://www.example.com in /etc/hosts file point it to 127.0.0.1 to open locally on instance. I have got one elastic ip address and associated it with the instance. I have changed http://www.example.com A's record with the elastic IP that I have got in above step. Now what should I do? When some user will open my website anywhere in the world, will it get pointed to my instanace's ip address? Have I done proper configurations for website on instance?

• Do ORMs enable the creation of rich domain models?

  - by Augusto

  After using Hibernate on most of my projects for about 8 years, I've landed on a company that discourages its use and wants applications to only interact with the DB through stored procedures. After doing this for a couple of weeks, I haven't been able to create a rich domain model of the application I'm starting to build, and the application just looks like a (horrible) transactional script. Some of the issues I've found are: Cannot navigate object graph as the stored procedures just load the minimum amount of data, which means that sometimes we have similar objects with different fields. One example is: we have a stored procedure to retrieve all the data from a customer, and another to retrieve account information plus a few fields from the customer. Lots of the logic ends up in helper classes, so the code becomes more structured (with entities used as old C structs). More boring scaffolding code, as there's no framework that extracts result sets from a stored procedure and puts it in an entity. My questions are: has anyone been in a similar situation and didn't agree with the store procedure approch? what did you do? Is there an actual benefit of using stored procedures? appart from the silly point of "no one can issue a drop table". Is there a way to create a rich domain using stored procedures? I know that there's the posibility of using AOP to inject DAOs/Repositories into entities to be able to navigate the object graph. I don't like this option as it's very close to voodoo.

• Edd strikes again &ndash; IronRuby for Rubyists on InfoQ

  - by Eric Nelson

  Colleague, friend and generally top guy on IronRuby Edd Morgan has just been published over on InfoQ. To wet the appetite… a snippet or three. IronRuby for Rubyists IronRuby is Microsoft's implementation of the Ruby language we all know and love with the added bonus of interoperability with the .NET framework — the Iron in the name is actually an acronym for 'Implementation running on .NET'. It's supported by the .NET Common Language Runtime as well as, albeit unofficially, the Mono project. You'd be forgiven for harbouring some question in your mind about running a dynamic language such as Ruby atop the CLR - that's where the DLR (Dynamic Language Runtime) comes in. The DLR is Microsoft's way of providing dynamic language capability on top of the CLR. Both IronRuby and the DLR are, as part of Microsoft's commitment to open source software, available as part of the Microsoft Public License on GitHub and CodePlex respectively… And Metaprogramming with IronRuby The art and science of metaprogramming — especially in Ruby, where it's an absolute joy — is something that could very easily span an entire article. As you would hope, IronRuby code is fully able to manipulate itself allowing you to bend your classes to your whim just as you would expect with a good dynamic language… And Riding the irails? So let's get to the point. I think it's a solid bet to make that a large proportion of Ruby programmers are familiar with the Rails framework - perhaps it's even safe to assume that most were first led to the Ruby language by the siren song of the Rails framework itself. Long story short, IronRuby is compatible enough to run your Rails app… Now… get yourself over to the full article and also check out some of Edds other work below.

• All files on automounted NTFS partition are marked as executable

  - by MHC

  I have set up an NTFS partition to automount via fstab: # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda7 during installation UUID=e63fa8a2-432f-4749-b9db-dab328807d04 / ext4 errors=remount-ro 0 1 # /boot was on /dev/sda4 during installation UUID=e9ad1bb4-7c1f-4ea9-a6a5-799dfad71c0a /boot ext4 defaults 0 2 # /home was on /dev/sda8 during installation UUID=eda8c755-5448-4de8-b58c-9cb75823c22d /home ext4 defaults 0 2 # swap was on /dev/sda9 during installation UUID=804ff3a7-e5dd-406a-b63c-e8f3c635fbc5 none swap sw 0 0 #Windows-Partition UUID=368CEBC57807FDCD /media/Share ntfs defaults,uid=1000,gid=1000,noexec 0 0 As you can see I have added the noexec bit to the configuration. Why? Because any file I create on or move to the partition is automatically marked as executable. The problem is that there is no way of changing that through nautilus. I cannot uncheck the "Allow executing file as program" option. The noexec option doesn't help, unfortunately. It only prevents nautilus from displaying the "run" or "read" dialog but doesn't change the executable flag. Is there any way I can fix this?

• Accessing a Web Service: Learning Resource needed

  - by abel

  I have been searching for resources to learn (Java) Web Services. Although I have found a lot of resources and tutorials on JWS, I am confused with the version numbers, the abbreviations and Metro. Plus the last update to Metro was in 2008. Is it a worthwile thing to learn? I wanted to learn how to access Web Services, since an upcoming project is about accessing one. I have some experience with OAuth on Twitter(using code available). Things I know about the project: I have to access a Web Service. Java is the preferred platform to use(Although I know I can use any). Axis can be used to access the Web Service(I have never used Axis) I have a meeting scheduled to learn more, but I sure don't want to look silly since I am no Java expert, have never created or accessed Web Services using Java. My Questions: 1.Can someone point me to a tutorial which will help me learn how to access a already running Web Service (Preferably SOAP(?), not REST. It's XML based) 2. Will you recommend using PHP or Python to do the work of accessing the web service? I am expecting a lot of nay saying, but I hope I get some answers too. I will clarify things if needed.

• Is it safe to delete "Account Unknown" entries from Windows ACLs in a domain environment?

  - by Graeme Donaldson

  It's not uncommon to see entries in Windows ACLs (NTFS files/folders, registry, AD objects, etc.) with the name "Account Unknown (SID)". Obviously these are because of old AD users or groups which at some point had permissions manually configured on the relevant object and have since been deleted. Does anyone know if it is safe to remove these "Account Unknown" ACEs? My gut feeling is that it should be just fine, but I'm wondering if anyone has any past experiences where doing this has caused trouble? Normally I just ignore these, but the company I'm working at now seems to have an abnormal number of these, most likely due to past admins' inexperience with AD/Windows and assigning permissions to user accounts rather than groups in all sorts of weird places. FWIW, our environment is not complex, a single domain forest, 4 DCs in 3 sites, with all network connectivity and replication healthy, so I'm certain that these "Account Unknown" entries are really old accounts, and not just because of some failure to resolve the SID to a human-readable name.

• Tail the filename, not the file

  - by Craig Walker

  In UNIX (OS X BSD to be precise), I have a "tail -f" command on a log file. From time to time I want to delete this log file so I can more easily review it in my text editor. I delete the file, and then my program recreates it after new activity. However, my tail command (and anything else that was watching the old log file) doesn't update; it's still watching the old, deleted log file. I think I understand why this is (file names simply being pointers to blocks of file data). I'd like to know how I can work around this. Ideally, my tail command (and anything else I point to the file) would be able to read the data from the new file when the file name has been deleted and recreated. How would I do this?

• Copying windows 8 Users folder having long long paths

  - by bilal.haider

  I was trying to move my "Users" folder in Windows 8 as described here and here. But when I try to copy the folder using "xcopy" in Windows Installation Disk Repair Mode, after some files are copied, I get "insufficient memory". The files on which the error is given are like C:\Users\Bilal\Application Data\Application Data\Application Data.........Application Data\Application Data..... What is the point in such directories within directories? I also tried copying them using Mini Windows XP, but the problem was there too.. Also tried copying using Parted Magic Live CD... but still.. So now, how can I move them? Another Question. Is moving such/ system files using Linux a good idea? Does it do anything to permissions?

• IBM x226 server with Windows 2003 freezing and showing one HDD degraded

  - by Zvonko Telefonko

  We have an IBM x226 server with Windows 2003 running on it. For weeks it's been very slow and it freezes at least once each day. At the boot it show message "degraded" for one HDD and optimal for other HDDs. We have 4 HDDs in it set up in Raid 1. HDD 1 - HDD 2, HDD 3 - HDD4. It seems that HDD2 is the one who is causing problems (showing degraded status). There's an amber led blinking on it together with the green one. We installed ServerRAID manager downloaded from IBM and it gave us option for "rebuild". But the server froze at some point and now it's rebuilding from start again. I've done some Googling and it says that it could be to failing HDD or some cache battery. How can we verify what is the cause of this?

• Planning in the Cloud - For Real

  - by jmorourke

  One of the hottest topics at Oracle OpenWorld 2012 this week is “the cloud”.  Over the past few years, Oracle has made major investments in cloud-based applications, including some acquisitions, and now has over 100 applications available through Oracle Cloud services.  At OpenWorld this week, Oracle announced seven new offerings delivered via the Oracle Cloud services platform, one of which is the Oracle Planning and Budgeting Cloud Service.  Based on Oracle Hyperion Planning, this service is the first of Oracle’s EPM applications to be to be offered in the Cloud.    This solution is targeted to organizations that are struggling with spreadsheets or legacy planning and budgeting applications, want to deploy a world class solution for financial planning and budgeting, but are constrained by IT resources and capital budgets. With the Oracle Planning and Budgeting Cloud Service, organizations can fast track their way to world-class financial planning, budgeting and forecasting – at cloud speed, with no IT infrastructure investments and with minimal IT resources. Oracle Hyperion Planning is a market-leading budgeting, planning and forecasting application that is used by over 3,300 organizations worldwide.  Prior to this announcement, Oracle Hyperion Planning was only offered on a license and maintenance basis.  It could be deployed on-premise, or hosted through Oracle On-Demand or third party hosting partners.  With this announcement, Oracle’s market-leading Hyperion Planning application will be available as a Cloud Service and through subscription-based pricing. This lowers the cost of entry and deployment for new customers and provides a scalable environment to support future growth. With this announcement, Oracle is the first major vendor to offer one of its core EPM applications as a cloud-based service.  Other major vendors have recently announced cloud-based EPM solutions, but these are only BI dashboards delivered via a cloud platform.   With this announcement Oracle is providing a market-leading, world-class financial budgeting, planning and forecasting as a cloud service, with the following advantages: ·                     Subscription-based pricing ·                     Available standalone or as an extension to Oracle Fusion Financials Cloud Service ·                     Implementation services available from Oracle and the Oracle Partner Network ·                     High scalability and performance ·                     Integrated financial reporting and MS Office interface ·                     Seamless integration with Oracle and non-Oracle transactional applications ·                     Provides customers with more options for their planning and budgeting deployment vs. strictly on-premise or cloud-only solution providers. The OpenWorld announcement of Oracle Planning and Budgeting Cloud Service is a preview announcement, with controlled availability expected in calendar year 2012.  For more information, check out the links below: Press Release Web site If you have any questions or need additional information, please feel free to contact me at [email protected].

• SQL SERVER – Curious Case of Disappearing Rows – ON UPDATE CASCADE and ON DELETE CASCADE – T-SQL Example – Part 2 of 2

  - by pinaldave

  Yesterday I wrote a real world story of how a friend who thought they have an issue with intrusion or virus whereas the issue was really in the code. I strongly suggest you read my earlier blog post Curious Case of Disappearing Rows – ON UPDATE CASCADE and ON DELETE CASCADE – Part 1 of 2 before continuing this blog post as this is second part of the first blog post. Let me reproduce the simple scenario in T-SQL. Building Sample Data USE [TestDB] GO -- Creating Table Products CREATE TABLE [dbo].[Products]( [ProductID] [int] NOT NULL, [ProductDesc] [varchar](50) NOT NULL, CONSTRAINT [PK_Products] PRIMARY KEY CLUSTERED ( [ProductID] ASC )) ON [PRIMARY] GO -- Creating Table ProductDetails CREATE TABLE [dbo].[ProductDetails]( [ProductDetailID] [int] NOT NULL, [ProductID] [int] NOT NULL, [Total] [int] NOT NULL, CONSTRAINT [PK_ProductDetails] PRIMARY KEY CLUSTERED ( [ProductDetailID] ASC )) ON [PRIMARY] GO ALTER TABLE [dbo].[ProductDetails] WITH CHECK ADD CONSTRAINT [FK_ProductDetails_Products] FOREIGN KEY([ProductID]) REFERENCES [dbo].[Products] ([ProductID]) ON UPDATE CASCADE ON DELETE CASCADE GO -- Insert Data into Table USE TestDB GO INSERT INTO Products (ProductID, ProductDesc) SELECT 1, 'Bike' UNION ALL SELECT 2, 'Car' UNION ALL SELECT 3, 'Books' GO INSERT INTO ProductDetails ([ProductDetailID],[ProductID],[Total]) SELECT 1, 1, 200 UNION ALL SELECT 2, 1, 100 UNION ALL SELECT 3, 1, 111 UNION ALL SELECT 4, 2, 200 UNION ALL SELECT 5, 3, 100 UNION ALL SELECT 6, 3, 100 UNION ALL SELECT 7, 3, 200 GO Select Data from Tables -- Selecting Data SELECT * FROM Products SELECT * FROM ProductDetails GO Delete Data from Products Table -- Deleting Data DELETE FROM Products WHERE ProductID = 1 GO Select Data from Tables Again -- Selecting Data SELECT * FROM Products SELECT * FROM ProductDetails GO Clean up Data -- Clean up DROP TABLE ProductDetails DROP TABLE Products GO My friend was confused as there was no delete was firing over ProductsDetails Table still there was a delete happening. The reason was because there is a foreign key created between Products and ProductsDetails Table with the keywords ON DELETE CASCADE. Due to ON DELETE CASCADE whenever is specified when the data from Table A is deleted and if it is referenced in another table using foreign key it will be deleted as well. Workaround 1: Design Changes – 3 Tables Change the design to have more than two tables. Create One Product Mater Table with all the products. It should historically store all the products list in it. No products should be ever removed from it. Add another table called Current Product and it should contain only the table which should be visible in the product catalogue. Another table should be called as ProductHistory table. There should be no use of CASCADE keyword among them. Workaround 2: Design Changes - Column IsVisible You can keep the same two tables. 1) Products and 2) ProductsDetails. Add a column with BIT datatype to it and name it as a IsVisible. Now change your application code to display the catalogue based on this column. There should be no need to delete anything. Workaround 3: Bad Advices (Bad advises begins here) The reason I have said bad advices because these are going to be bad advices for sure. You should make necessary design changes and not use poor workarounds which can damage the system and database integrity further. Here are the examples 1) Do not delete the data – well, this is not a real solution but can give time to implement design changes. 2) Do not have ON CASCADE DELETE – in this case, you will have entry in productsdetails which will have no corresponding product id and later on there will be lots of confusion. 3) Duplicate Data – you can have all the data of the product table move to the product details table and repeat them at each row. Now remove CASCADE code. This will let you delete the product table rows without any issue. There are so many things wrong this suggestion, that I will not even start here. (Bad advises ends here)  Well, did I miss anything? Please help me with your suggestions.

• Masters vs. PhD - long [closed]

  - by Sterling

  I'm 21 years old and a first year master's computer science student. Whether or not to continue with my PhD has been plaguing me for the past few months. I can't stop thinking about it and am extremely torn on the issue. I have read http://www.cs.unc.edu/~azuma/hitch4.html and many, many other masters vs phd articles on the web. Unfortunately, I have not yet come to a conclusion. I was hoping that I could post my ideas about the issue on here in hopes to 1) get some extra insight on the issue and 2) make sure that I am correct in my assumptions. Hopefully having people who have experience in the respective fields can tell me if I am wrong so I don't make my decision based on false ideas. Okay, to get this topic out of the way - money. Money isn't the most important thing to me, but it is still important. It's always been a goal of mine to make 6 figures, but I realize that will probably take me a long time with either path. According to most online salary calculating sites, the average starting salary for a software engineer is ~60-70k. The PhD program here is 5 years, so that's about 300k I am missing out on by not going into the workforce with a masters. I have only ever had ~1k at one time in my life so 300k is something I can't even really accurately imagine. I know that I wouldn't have at once obviously, but just to know I would be earning that is kinda crazy to me. I feel like I would be living quite comfortably by the time I'm 30 years old (but risk being too content too soon). I would definitely love to have at least a few years of my 20s to spend with that kind of money before I have a family to spend it all on. I haven't grown up very financially stable so it would be so nice to just spend some money…get a nice car, buy a new guitar or two, eat some good food, and just be financially comfortable. I have always felt like I deserved to make good money in my life, even as a kid growing up, and I just want to have it be a reality. I know that either path I take will make good money by the time I'm ~40-45 years old, but I guess I'm just sick of not making money and am getting impatient about it. However, a big idea pushing me towards a PhD is that I feel the masters path would give me a feeling of selling out if I have the capability to solve real questions in the computer science world. (pretty straight-forward - not much to elaborate on, but this is a big deal) Now onto other aspects of the decision. I originally got into computer science because of programming. I started in high school and knew very soon that it was what I wanted to do for a career. I feel like getting a masters and being a software engineer in the industry gives me much more time to program in my career. In research, I feel like I would spend more time reading, writing, trying to get grant money, etc than I would coding. A guy I work with in the lab just recently published a paper. He showed it to me and I was shocked by it. The first two pages was littered with equations and formulas. Then the next page or so was followed by more equations and formulas that he derived from the previous ones. That was his work - breaking down and creating all of these formulas for robotic arm movement. And whenever I read computer science papers, they all seem to follow this pattern. I always pictured myself coding all day long…not proving equations and things of that nature. I know that's only one part of computer science research, but that part bores me. A couple cons on each side - Phd - I don't really enjoy writing or feel like I'm that great at technical writing. Whenever I'm in groups to make something, I'm always the one who does the large majority of the work and then give it to my team members to write up a report. Presenting is different though - I don't mind presenting at all as long as I have a good grasp on what I am presenting. But writing papers seems like such a chore to me. And because of this, the "publish or perish" phrase really turns me off from research. Another bad thing - I feel like if I am doing research, most of it would be done alone. I work best in small groups. I like to have at least one person to bounce ideas off of when I am brainstorming. The idea of being a part of some small elite group to build things sounds ideal to me. So being able to work in small groups for the majority of my career is a definite plus. I don't feel like I can get this doing research. Masters - I read a lot online that most people come in as engineers and eventually move into management positions. As of now, I don't see myself wanting to be a part of management. Lets say my company wanted to make some new product or system - I would get much more pride, enjoyment, and overall satisfaction to say "I made this" rather than "I managed a group of people that made this." I want to be a big part of the development process. I want to make things. I think it would be great to be more specialized than other people. I would rather know everything about something than something about everything. I always have been that way - was a great pitcher during my baseball years, but not so good at everything else, great at certain classes in school, but not so good at others, etc. To think that my career would be the same way sounds okay to me. Getting a PhD would point me in this direction. It would be great to be some guy who is someone that people look towards and come to ask for help because of being such an important contributor to a very specific field, such as artificial neural networks or robotic haptic perception. From what I gather about the software industry, being specialized can be a very bad thing because of the speed of the new technology. I When it comes to being employed, I have pretty conservative views. I don't want to change companies every 5 years. Maybe this is something everyone wishes, but I would love to just be an important person in one company for 10+ (maybe 20-25+ if I'm lucky!) years if the working conditions were acceptable. I feel like that is more possible as a PhD though, being a professor or researcher. The more I read about people in the software industry, the more it seems like most software engineers bounce from company to company at rapid paces. Some even work like a hired gun from project to project which is NOT what I want AT ALL. But finding a place to make great and important software would be great if that actually happens in the real world. I'm a very competitive person. I thrive on competition. I don't really know why, but I have always been that way even as a kid growing up. Competition always gave me a reason to practice that little extra every night, always push my limits, etc. It seems to me like there is no competition in the research world. It seems like everyone is very relaxed as long as research is being conducted. The only competition is if someone is researching the same thing as you and its whoever can finish and publish first (but everyone seems to careful to check that circumstance). The only noticeable competition to me is just with yourself and your own discipline. I like the idea that in the industry, there is real competition between companies to put out the best product or be put out of business. I feel like this would constantly be pushing me to be better at what I do. One thing that is really pushing me towards a PhD is the lifetime of the things you make. I feel like if you make something truly innovative in the industry…just some really great new application or system…there is a shelf-life of about 5-10 years before someone just does it faster and more efficiently. But with research work, you could create an idea or algorithm that last decades. For instance, the A* search algorithm was described in 1968 and is still widely used today. That is amazing to me. In the words of Palahniuk, "The goal isn't to live forever, its to create something that will." Over anything, I just want to do something that matters. I want my work to help and progress society. Seriously, if I'm stuck programming GUIs for the next 40 years…I might shoot myself in the face. But then again, I hate the idea that less than 1% of the population will come into contact with my work and even less understand its importance. So if anything I have said is false then please inform me. If you think I come off as a masters or PhD, inform me. If you want to give me some extra insight or add on to any point I made, please do. Thank you so much to anyone for any help.

• Slow USB 3.0 speeds

  Long time forum forager, first time poster. I bought a Toshiba 500 GB usb 3.0 hard drive last week and instantly ran home to see how fast I could push it. On my desktop (that I built) I was able to get 200 MB/sec. On my laptop (MSI FX something or other), which I dual boot Windows 7/Ubuntu 11.10, I was able to get about 120 MB/sec on Windows, but on Ubuntu, i get about 25 MB/sec. lsusb shows: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 8087:0020 Intel Corp.

Not really sure what to do at this point. Any help would be very nice, thank you.

• Using template questions in a technical interview

  - by Desolate Planet

  I've recently been in an argument with a colleage about technical questions in interviews. As a graduate, I went round lots of companies and noticed they used the same questions. An example is "Can you write a function that determines if a number is prime or not?", 4 years later, I find that particular question is quite common even for a junior developer. I might not be looking at this the correct way, but shouldn't software houses be intelligent enought to think up their own interview questions. This may well be the case, but I've been to about 16 interviews as a graduate and the same questions came up in about 75% of them. This leads me to believe that many companies are lazy and simply Google: 'Template questions for interviewing software developers' and I kind of look down on that. Question: Is it better to use a sest of questions off some template or should software houses strive to be more original and come up with their own interview material? From my point of view, if I failed an inteview and went off and looked for good answers to the questions I messed up on, I could fly through the next interview if they questions are the same.

• Virtualmin Configuration

  - by Allen

  I am trying to get Virtualmin setup and have reached a point where my noobish sysadmin skills aren't getting the job done. This is the message I get now when I try and refresh the configuration of Virtualmin. BIND DNS server is installed, and the system is configured to use it. However, the default master DNS server XXXXXX is not a fully qualified domain name. Sendmail is only accepting SMTP connections on the following ports : 127.0.0.1 port smtp. Email from other systems on the Internet will not be accepted. This can be changed in the Sendmail Mail Server module. Please advise what I need to do to get Sendmail configured properly. Thanks!

• Personal Software Process (PSP1)

  - by gentoo_drummer

  I'm trying to figure out an exercise but it doesn't really makes to much sense.. I'm not asking someone to provide the solution. just to try and analyse what needs to be done in order to solve this. I'm trying to understand which PSP 1.0 1.1 process I should use. PROBE? Or something else? I would greatly appreciate some help on this one from someone that has experience with the Personal Software Process Methodology.. Here is the question. For the reference case (“code1.c”), the following s/w metrics are provided: man-hours spent in implementation phase (per-module): 2,7 mh/file man-hours spent in testing phase (per-module): 4,3 mh/file estimated number of bugs remaining (per-module): 0,3 errors/function, 4 errors/module (remaining) Based on the corresponding values provided for the reference case, each of the following tasks focus on some s/w metrics to be estimated for the test case (“code2.c”): [25 marks] (estimated) man-hours required in implementation phase (per-module) [8 marks] (estimated) man-hours required in testing phase (per-module) [8 marks] (estimated) number of bugs remaining at the end of testing phase (per-module) [9 marks] Tasks 4 through 6 should use the data provided for the reference case within the context of Personal Software Process level-1 (PSP-1), using them as a single-point historic data log. Specifically, the same s/w metrics are to be estimated for the test case (“code2.c”), using PSP as the basic estimation model. In order to perform the above listed tasks, students are advised to consider all phases of the PSP software development process, especially at levels PSP0 and PSP1. Both cases are to be treated as separate case-studies in the context of classic s/w development.

• IP stops working from time to time

  - by Mattias

  Hi, have a problem that I can't seem to find the reason for. We are running a small network with windows clients(XP/Win7) and windows servers(2008 sp2/2008r2). The domaincontroller is working as DC, DNS, DHCP, VPN. We have a Level1 FBR4000 between internet and our internal network. The problem is that from time to time specific IP-adresses stops working, the only way I have gotten the devices to work again is to exclude the specific IP from the DHCP address pool and getting a new IP, then everything works again. It seems as the specific IP is beeing banned/blocked somewhere but I just can't figure out where. Anyone got an idea as to where I should start to look? I could also point out that I just reinstalled all servers due to a officemove and was hoping to get away from this problem but it just showed up again. This last time it was my iPhone that got stuck through the Wi-Fi...

• Book Review&ndash;Getting Started With OAuth 2.0

  - by Lori Lalonde

  Getting Started With OAuth 2.0, by Ryan Boyd, provides an introduction to the latest version of the OAuth protocol. The author starts off by exploring the origins of OAuth, along with its importance, and why developers should care about it. The bulk of this book involves a discussion of the various authorization flows that developers will need to consider when developing applications that will incorporate OAuth to manage user access and authorization. The author explains in detail which flow is appropriate to use based on the application being developed, as well as how to implement each type with step-by-step examples. Note that the examples in the book are focused on the Google and Facebook APIs. Personally, I would have liked to see some examples with the Twitter API as well. In addition to that, the author also discusses security considerations, error handling (what is returned if the access request fails), and access tokens (when are access tokens refreshed, and how access can be revoked). This book provides a good starting point for those developers looking to understand what OAuth is and how they can leverage it within their own applications. The book wraps up with a list of tools and libraries that are available to further assist the developer in exploring the APIs supporting the OAuth specification. I highly recommend this book as a must-read for developers at all levels that have not yet been exposed to OAuth. The eBook format of this book was provided free through O'Reilly's Blogger Review program. This book can be purchased from the O'Reilly book store at: : http://shop.oreilly.com/product/0636920021810.do

• How can I use domain masking without having self referral in Google Analytics

  - by Cdore

  I have one old domain that points to a website's server's ip (let's call it www.oldsite.com). I have a new one, www.newsite.com, that is set up to be forwarded to a specific page on the website. Due to the way the host of newsite.com places the website in a frame, in Google Analystics, the newsite.com is listed as a source rather than the source they were at before hand, causing a self referral. A solution is to edit the code of the iframe as I looked up, but there's no way to really edit the host's masking source code of course. Another solution I did previously was have www.newsite.com point to the address that www.oldsite.come pointed to. It solved the analytics problems, but in exchange, the url masking no longer worked. In the address bar, it came up as www.oldsite.com. Is there a way to make me have url masking and be able to forward to agree with google analytics? The server of the website is hosted on a cloud server, if this is anymore information.
