  • Can any web-based email program let user paste an image (not link) as part of the email instead of a

    - by Jian Lin
    I think back in the old days, some email programs let users Paste an image right inside the email content. (maybe WinMail or Outlook?) So for example, we can write some text, embed an image, and then write some more text, and embed another image. The recipient will get the email content in the above text-image-text-image order (instead of having all images attached at the end of email) Can any web-based email program do that? Note that the image is not just a link, but a complete file. For example, Gmail lets us paste an image, but it is actually just a link to some web location. Can the actual file content be embedded instead?

  • I have only two languages on my resume - how bad is this?

    - by Karl
    Hi there! I have a question that can be best answered here, given the vast experience some of you guys have! I am going to finish my bachelor's degree in CS and let's face it, I am just comfortable with C++ and Python. C++ - I have no experience to show for and I can't quote the C++ standard like some of the guys on SO do but yet I am comfortable with the language basics and the stuff that mostly matters. With Python, I have demonstrated work experience with a good company, so I can safely put that. I have never touched C, though I have been meaning to do it now. So I cannot write C on my resume because I have not done it ever. Sure I can finish K & R and get a sense of the language in a month, but I don't feel like writing it cause that would be being unfaithful to myself. So the big question is, are two languages on a a resume considered OK or that is usually a bad sign? Most resumes I have seen mention lots of languages and hence my question. Under the language section of my resume, I just mention: C++ and Python and that kinda looks empty! What are your views on this and what do you feel about such a situation? PS: I really don't want to write every single library or API I am familiar with. Or should I?

  • SQL SERVER – Difference Between DATETIME and DATETIME2 – WITH GETDATE

    - by pinaldave
    Earlier I wrote blog post SQL SERVER – Difference Between GETDATE and SYSDATETIME which inspired me to write SQL SERVER – Difference Between DATETIME and DATETIME2. Now earlier two blog post inspired me to write this blog post (and 4 emails and 3 reads from readers). I previously populated DATETIME and DATETIME2 field with SYSDATETIME, which gave me very different behavior as SYSDATETIME was rounded up/down for the DATETIME datatype. I just ran the same experiment but instead of populating SYSDATETIME in this script I will be using GETDATE function. DECLARE @Intveral INT SET @Intveral = 10000 CREATE TABLE #TimeTable (FirstDate DATETIME, LastDate DATETIME2) WHILE (@Intveral > 0) BEGIN INSERT #TimeTable (FirstDate, LastDate) VALUES (GETDATE(), GETDATE()) SET @Intveral = @Intveral - 1 END GO SELECT COUNT(DISTINCT FirstDate) D_FirstDate, COUNT(DISTINCT LastDate) D_LastDate FROM #TimeTable GO SELECT DISTINCT a.FirstDate, b.LastDate FROM #TimeTable a INNER JOIN #TimeTable b ON a.FirstDate = b.LastDate GO SELECT * FROM #TimeTable GO DROP TABLE #TimeTable GO Let us run above script and observe the results. You will find that the values of GETDATE which is populated in both the columns FirstDate and LastDate are very much same. This is because GETDATE is of datatype DATETIME and the precision of the GETDATE is smaller than DATETIME2 there is no rounding happening. In other word, this experiment is pointless. I have included this as I got 4 emails and 3 twitter questions on this subject. If your datatype of variable is smaller than column datatype there is no manipulation of data, if data type of variable is larger than column datatype the data is rounded.

  • Learn Domain-Driven Design

    - by Ben Griswold
    I just wrote about how I like to present on unfamiliar topics. With this said, Domain-Driven Design (DDD) is no exception. This is yet another area I knew enough about to be dangerous but I certainly was no expert.  As it turns out, researching this topic wasn’t easy. I could be wrong, but it is as if DDD is a secret to which few are privy. If you search the Interwebs, you will likely find little information about DDD until you start rolling over rocks to find that one great write-up, a handful of podcasts and videos and the Readers’ Digest version of the Blue Book which apparently you must read if you really want to get the complete, unabridged skinny on DDD.  Even Wikipedia’s write-up is skimpy which I didn’t know was possible…   Here’s a list of valuable resources.  If you, too, are interested in DDD, this is a good starting place.  Domain-Driven Design: Tackling Complexity in the Heart of Software by Eric Evans Domain-Driven Design Quickly, by Abel Avram & Floyd Marinescu An Introduction to Domain-Driven Design by David Laribee Talking Domain-Driven Design with David Laribee Part 1, Deep Fried Bytes Talking Domain-Driven Design with David Laribee Part 2, Deep Fried Bytes Eric Evans on Domain Driven Design, .NET Rocks Domain-Driven Design Community Eric Evans on Domain Driven Design Jimmy Nilsson on Domain Driven Design Domain-Driven Design Wikipedia What I’ve Learned About DDD Since the Book, Eric Evans Domain Driven Design, Alt.Net Podcast Applying Domain-Driven Design and Patterns: With Examples in C# and .NET, Jimmy Nilsson Domain-Driven Design Discussion Group DDD: Putting the Model to Work by Eric Evans The Official DDD Site

  • SQL SERVER – Guest Post – Jonathan Kehayias – Wait Type – Day 16 of 28

    - by pinaldave
    Jonathan Kehayias (Blog | Twitter) is a MCITP Database Administrator and Developer, who got started in SQL Server in 2004 as a database developer and report writer in the natural gas industry. After spending two and a half years working in TSQL, in late 2006, he transitioned to the role of SQL Database Administrator. His primary passion is performance tuning, where he frequently rewrites queries for better performance and performs in depth analysis of index implementation and usage. Jonathan blogs regularly on SQLBlog, and was a coauthor of Professional SQL Server 2008 Internals and Troubleshooting. On a personal note, I think Jonathan is extremely positive person. In every conversation with him I have found that he is always eager to help and encourage. Every time he finds something needs to be approved, he has contacted me without hesitation and guided me to improve, change and learn. During all the time, he has not lost his focus to help larger community. I am honored that he has accepted to provide his views on complex subject of Wait Types and Queues. Currently I am reading his series on Extended Events. Here is the guest blog post by Jonathan: SQL Server troubleshooting is all about correlating related pieces of information together to indentify where exactly the root cause of a problem lies. In my daily work as a DBA, I generally get phone calls like, “So and so application is slow, what’s wrong with the SQL Server.” One of the funny things about the letters DBA is that they go so well with Default Blame Acceptor, and I really wish that I knew exactly who the first person was that pointed that out to me, because it really fits at times. A lot of times when I get this call, the problem isn’t related to SQL Server at all, but every now and then in my initial quick checks, something pops up that makes me start looking at things further. The SQL Server is slow, we see a number of tasks waiting on ASYNC_IO_COMPLETION, IO_COMPLETION, or PAGEIOLATCH_* waits in sys.dm_exec_requests and sys.dm_exec_waiting_tasks. These are also some of the highest wait types in sys.dm_os_wait_stats for the server, so it would appear that we have a disk I/O bottleneck on the machine. A quick check of sys.dm_io_virtual_file_stats() and tempdb shows a high write stall rate, while our user databases show high read stall rates on the data files. A quick check of some performance counters and Page Life Expectancy on the server is bouncing up and down in the 50-150 range, the Free Page counter consistently hits zero, and the Free List Stalls/sec counter keeps jumping over 10, but Buffer Cache Hit Ratio is 98-99%. Where exactly is the problem? In this case, which happens to be based on a real scenario I faced a few years back, the problem may not be a disk bottleneck at all; it may very well be a memory pressure issue on the server. A quick check of the system spec’s and it is a dual duo core server with 8GB RAM running SQL Server 2005 SP1 x64 on Windows Server 2003 R2 x64. Max Server memory is configured at 6GB and we think that this should be enough to handle the workload; or is it? This is a unique scenario because there are a couple of things happening inside of this system, and they all relate to what the root cause of the performance problem is on the system. If we were to query sys.dm_exec_query_stats for the TOP 10 queries, by max_physical_reads, max_logical_reads, and max_worker_time, we may be able to find some queries that were using excessive I/O and possibly CPU against the system in their worst single execution. We can also CROSS APPLY to sys.dm_exec_sql_text() and see the statement text, and also CROSS APPLY sys.dm_exec_query_plan() to get the execution plan stored in cache. Ok, quick check, the plans are pretty big, I see some large index seeks, that estimate 2.8GB of data movement between operators, but everything looks like it is optimized the best it can be. Nothing really stands out in the code, and the indexing looks correct, and I should have enough memory to handle this in cache, so it must be a disk I/O problem right? Not exactly! If we were to look at how much memory the plan cache is taking by querying sys.dm_os_memory_clerks for the CACHESTORE_SQLCP and CACHESTORE_OBJCP clerks we might be surprised at what we find. In SQL Server 2005 RTM and SP1, the plan cache was allowed to take up to 75% of the memory under 8GB. I’ll give you a second to go back and read that again. Yes, you read it correctly, it says 75% of the memory under 8GB, but you don’t have to take my word for it, you can validate this by reading Changes in Caching Behavior between SQL Server 2000, SQL Server 2005 RTM and SQL Server 2005 SP2. In this scenario the application uses an entirely adhoc workload against SQL Server and this leads to plan cache bloat, and up to 4.5GB of our 6GB of memory for SQL can be consumed by the plan cache in SQL Server 2005 SP1. This in turn reduces the size of the buffer cache to just 1.5GB, causing our 2.8GB of data movement in this expensive plan to cause complete flushing of the buffer cache, not just once initially, but then another time during the queries execution, resulting in excessive physical I/O from disk. Keep in mind that this is not the only query executing at the time this occurs. Remember the output of sys.dm_io_virtual_file_stats() showed high read stalls on the data files for our user databases versus higher write stalls for tempdb? The memory pressure is also forcing heavier use of tempdb to handle sorting and hashing in the environment as well. The real clue here is the Memory counters for the instance; Page Life Expectancy, Free List Pages, and Free List Stalls/sec. The fact that Page Life Expectancy is fluctuating between 50 and 150 constantly is a sign that the buffer cache is experiencing constant churn of data, once every minute to two and a half minutes. If you add to the Page Life Expectancy counter, the consistent bottoming out of Free List Pages along with Free List Stalls/sec consistently spiking over 10, and you have the perfect memory pressure scenario. All of sudden it may not be that our disk subsystem is the problem, but is instead an innocent bystander and victim. Side Note: The Page Life Expectancy counter dropping briefly and then returning to normal operating values intermittently is not necessarily a sign that the server is under memory pressure. The Books Online and a number of other references will tell you that this counter should remain on average above 300 which is the time in seconds a page will remain in cache before being flushed or aged out. This number, which equates to just five minutes, is incredibly low for modern systems and most published documents pre-date the predominance of 64 bit computing and easy availability to larger amounts of memory in SQL Servers. As food for thought, consider that my personal laptop has more memory in it than most SQL Servers did at the time those numbers were posted. I would argue that today, a system churning the buffer cache every five minutes is in need of some serious tuning or a hardware upgrade. Back to our problem and its investigation: There are two things really wrong with this server; first the plan cache is excessively consuming memory and bloated in size and we need to look at that and second we need to evaluate upgrading the memory to accommodate the workload being performed. In the case of the server I was working on there were a lot of single use plans found in sys.dm_exec_cached_plans (where usecounts=1). Single use plans waste space in the plan cache, especially when they are adhoc plans for statements that had concatenated filter criteria that is not likely to reoccur with any frequency.  SQL Server 2005 doesn’t natively have a way to evict a single plan from cache like SQL Server 2008 does, but MVP Kalen Delaney, showed a hack to evict a single plan by creating a plan guide for the statement and then dropping that plan guide in her blog post Geek City: Clearing a Single Plan from Cache. We could put that hack in place in a job to automate cleaning out all the single use plans periodically, minimizing the size of the plan cache, but a better solution would be to fix the application so that it uses proper parameterized calls to the database. You didn’t write the app, and you can’t change its design? Ok, well you could try to force parameterization to occur by creating and keeping plan guides in place, or we can try forcing parameterization at the database level by using ALTER DATABASE <dbname> SET PARAMETERIZATION FORCED and that might help. If neither of these help, we could periodically dump the plan cache for that database, as discussed as being a problem in Kalen’s blog post referenced above; not an ideal scenario. The other option is to increase the memory on the server to 16GB or 32GB, if the hardware allows it, which will increase the size of the plan cache as well as the buffer cache. In SQL Server 2005 SP1, on a system with 16GB of memory, if we set max server memory to 14GB the plan cache could use at most 9GB  [(8GB*.75)+(6GB*.5)=(6+3)=9GB], leaving 5GB for the buffer cache.  If we went to 32GB of memory and set max server memory to 28GB, the plan cache could use at most 16GB [(8*.75)+(20*.5)=(6+10)=16GB], leaving 12GB for the buffer cache. Thankfully we have SQL Server 2005 Service Pack 2, 3, and 4 these days which include the changes in plan cache sizing discussed in the Changes to Caching Behavior between SQL Server 2000, SQL Server 2005 RTM and SQL Server 2005 SP2 blog post. In real life, when I was troubleshooting this problem, I spent a week trying to chase down the cause of the disk I/O bottleneck with our Server Admin and SAN Admin, and there wasn’t much that could be done immediately there, so I finally asked if we could increase the memory on the server to 16GB, which did fix the problem. It wasn’t until I had this same problem occur on another system that I actually figured out how to really troubleshoot this down to the root cause.  I couldn’t believe the size of the plan cache on the server with 16GB of memory when I actually learned about this and went back to look at it. SQL Server is constantly telling a story to anyone that will listen. As the DBA, you have to sit back and listen to all that it’s telling you and then evaluate the big picture and how all the data you can gather from SQL about performance relate to each other. One of the greatest tools out there is actually a free in the form of Diagnostic Scripts for SQL Server 2005 and 2008, created by MVP Glenn Alan Berry. Glenn’s scripts collect a majority of the information that SQL has to offer for rapid troubleshooting of problems, and he includes a lot of notes about what the outputs of each individual query might be telling you. When I read Pinal’s blog post SQL SERVER – ASYNC_IO_COMPLETION – Wait Type – Day 11 of 28, I noticed that he referenced Checking Memory Related Performance Counters in his post, but there was no real explanation about why checking memory counters is so important when looking at an I/O related wait type. I thought I’d chat with him briefly on Google Talk/Twitter DM and point this out, and offer a couple of other points I noted, so that he could add the information to his blog post if he found it useful.  Instead he asked that I write a guest blog for this. I am honored to be a guest blogger, and to be able to share this kind of information with the community. The information contained in this blog post is a glimpse at how I do troubleshooting almost every day of the week in my own environment. SQL Server provides us with a lot of information about how it is running, and where it may be having problems, it is up to us to play detective and find out how all that information comes together to tell us what’s really the problem.

  • Building services with .Net Part 1

    - by Allan Rwakatungu
    On the 26th of May 2010 , I made a presentation to the .NET user group meeting (thanks to Malisa Ncube for organizing this event every month … ). If you missed my presentation , we talked about why we should all be building services … better still using the .NET framework. This blog post is an introduction to services , why you would want to build services and how you can build services using the .NET framework. What is a service? OASIS defines service as "a mechanism to enable access to one or more capabilities, where the access is provided using a prescribed interface and is exercised consistent with constraints and policies as specified by the service description." [1]. If the above definition sounds to academic , you can also define a service as loosely coupled units of functionality that have no calls to each other embedded in the. Instead of services embedding calls to each other in their service code they use defined protocols that describe how services pass and parse messages. This is a good way to think about services if you’re from an objected oriented background. While in object oriented programming functions make calls to each other, in service oriented programming, functions pass messages between each other. Why would you want to use services? 1. If your enterprise architecture looks like this   Services are the building blocks for SOA . With SOA you can move away from the sphaggetti infrastructure that is common in most enterprises. The complexity or lack of visibility of the integration points in your enterprises makes it difficult and costly to implement new initiatives and changes into the business - and even impossible in some cases - as it is not possible to identify the impact a change in one system might have to other systems. With services you can move to an architecture like this Your building blocks from Spaghetti infrastructure to something that is more well-defined and manageable to achieve cost efficiency and not least business agility - enabling you to react to changes in the market with speed and achieve operational efficiency and control are services. 2. If you want to become the Gates or Zuckerburger. Have you heard about Web 2.0 ? Mashups? Software as a service (SAAS) ? Cloud computing ?   They all offer you the opportunity to have scalable but low cost business models and they built using services.  Some of my favorite companies that leverage services for their business models include  https://www.salesforce.com/ (cloud CRM) http://www. twitter.com (more people use twitter clients built by 3rd parties than their official clients) http://www.kayak.com/ (compares data from other travel sites to give information to users in one location) Services with the .NET framework      If you are a .NET developer and you want to develop services, Windows Communication Framework (WCF) is the tool for you. WCF is Microsoft’s unified programming model (service model) for building service oriented applications. ( Before .NET 3.0 you had several models for programming services in .NET including .NET remoting, Web services (ASMX), COM +, Microsoft Messaging queuing (MSMQ) etc, after .NET 3.0 the programming model was unified into one i.e. WCF ). Windows Communication Framework (WCF) provides you 1. An Software Development Kit (SDK) for creating SOA applications 2. A runtime for running services on the Windows platform Why should you use Windows Communication Foundation if you’re programming services?   1. It supports interoperable and open standards e.g. WS* protocols for programming SOAP services 2. It has a unified programming model. Whether you use TCP or Http or Pipes or transmitting using Messaging Queues, programmers need to learn just one way to program. Previously you had .NET remoting, MSMQ, Web services, COM+ and they were all done differently 3. Productive programming model You don’t have to worry about all the plumbing involved to write services. You have a rich declarative programming model to add stuff like logging, transactions, and reliable messages in-built in the Windows Communication Framework. Understanding services in WCF The basic principles of WCF are as easy as ABC A – Address This is where the service is located B- Binding This describes how you communicate with the service e.g. Use TCP, HTTP or both. How to exchange security information with the service etc. C – Contract This defines what the service can do. E.g. Pay water bill, Make a phone call A - Addresses In WCF, an address is a combination of transport, server name, port and path Example addresses may include http://localhost:8001 net.tcp://localhost:8002/MyService net.pipe://localhost/MyPipe net.msmq://localhost/private/MyService net.msmq://localhost/MyService B- Binding   There are numerous ways to communicate with services , different ways that a message can be formatted/sent/secured, that allows you to tailor your service for the compatibility/performance you require for your solution. Transport You can use HTTP TCP MSMQ , Named pipes, Your own custom transport etc Message You  can send a plain text binary, Message Transmission Optimization Mechanism (MTOM) message Communication security No security Transport security Message security Authenticating and authorizing callers etc Behaviour You service can support Transactions Be reliable Use queues Support ajax etc C - Contract You define what your service can do using Service contracts :- Define operations that your service can do, communications and behaviours Data contracts :- Define the messages that are passed from and into your service and how they are formatted Fault contracts :- Defines errors types in your service   As an example, suppose your service service shows money. You define your service contract using a interface [ServiceContract] public interface IShowMeTheMoney {   [OperationContract]    Money Show(); } You define the data contract by annotating a class it with the Data Contract attribute and fields you want to pass in the message as Data Members. (Note:- In the latest versions of WCF you dont have to use attributes if you passing all the objects properties in the message) [DataContract] public Money {   [DataMember]   public string Currency { get; set; }   [DataMember]   public Decimal Amount { get; set; }   public string Comment { get; set; } } Features of Windows Communication Foundation Windows Communication Foundation is not only simple but feature rich , offering you several options to tweak your service to fit your business requirements. Some of the features of WCF include 1. Workflow services You can combine WCF with Windows WorkFlow Foundation (WWF) to write workflow type services 2. Control how your data (messages) are transferred and serialized e.g. you can serialize your business objects as XML or binary 3. control over session management , instance creation and concurrency management without writing code if you like 4. Queues and reliable sessions. You can store messages from the sending client and later forward them to the receiving application. You can also guarantee that messages will arrive at their destincation. 5.Transactions:  You can have different services participate in a transaction operations that can be rolled back if needed 6. Security. WCF has rich features for authorization and authentication  as well as keep audit trails 7. Web programming model. WCF allows developers to expose services as non SOAP endpoints 8. Inbuilt features that you can use to write JSON and services that support AJAX applications And lots more In my next blog I will show you how you can use WCF features to write a real world business service.               Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 ]] /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  • Writing a Book, and Moving my Blog

    - by Ben Nevarez
    I started blogging about SQL Server here at SQLblog back in July, 2009 and it was a lot of fun, I enjoyed it a lot. Then later, after a series of blog posts about the Query Optimizer, I was invited to write an entire book about that same topic. But after a few months I realized that it was going to be hard to continue both blogging and writing chapters for a book, this in addition to my regular day job, so I decided to stop blogging for a little while.   Now that I have finished the last chapter of the book and I am working on the final chapter reviews, I decided to start blogging again. This time I am moving my blog to   http://www.benjaminnevarez.com   Same as my previous posts I plan to write about my topics of interest, like the relational engine, and basically anything related to SQL Server. Hopefully you find my new blog interesting and useful.   Finally, I would like to thank Adam for allowing me to blog here.

  • OpenSSL Handshake Failure (14094410) - Erroneous Client Certificate Check from Mobile Phone

    - by Clayton Sims
    I'm running a proxy server through Apache with modssl, which we're using to proxy POSTs from mobile devices to another internal server. This works successfully for most clients, but requests from a specific phone model (Nokia 2690) are showing a bizarre handshake failure. It looks as though OpenSSL is either requesting (or attempting to read an unsolicited) client certificate from the phone (which is especially bizarre because j2me's kssl implementation doesn't support client certs). I've disabled client certificates with the SSLVerifyClient none directive in both the virtual host conf and the modssl conf. The trace from error.log on debug level is (details redacted): [client 41.220.207.10] Connection to child 0 established (server www.myserver.org:443) [info] Seeding PRNG with 656 bytes of entropy [debug] ssl_engine_kernel.c(1866): OpenSSL: Handshake: start [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: before/accept initialization [debug] ssl_engine_io.c(1882): OpenSSL: read 11/11 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d0] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1882): OpenSSL: read 49/49 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90db] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 read client hello A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write server hello A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write certificate A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 write server done A [debug] ssl_engine_kernel.c(1874): OpenSSL: Loop: SSLv3 flush data [debug] ssl_engine_io.c(1882): OpenSSL: read 5/5 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d0] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1882): OpenSSL: read 2/2 bytes from BIO#7fe3fbaf17a0 [mem: 7fe3fbaf90d5] (BIO dump follows) [debug] ssl_engine_io.c(1815): +-------------------------------------------------------------------------+ [debug] ssl_engine_io.c(1860): +-------------------------------------------------------------------------+ [debug] ssl_engine_kernel.c(1879): OpenSSL: Read: SSLv3 read client certificate A [debug] ssl_engine_kernel.c(1898): OpenSSL: Exit: failed in SSLv3 read client certificate A [client 41.220.207.10] SSL library error 1 in handshake (server www.myserver.org:443) [info] SSL Library Error: 336151568 error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure [client 41.220.207.10] Connection closed to child 0 with abortive shutdown (server www.myserver.org:443) I've tried enabling all ciphers and all protocols temporarily with modssl, neither of which seemed to be the issue. The phone should be using RSA_RC4_128_MD5 and SSLv3, all of which are available. Am I missing something more fundamental about what's failing here? It seemed like the certificate request might have been part of a renegotiation failure. I tried enabling SSLInsecureRenegotiation On on the virtual host, in case it was an issue of the phone's SSL not supporting the new protocol, but to no avail.

  • Does software architect/designer require more skills and intellectual than software engineer (implementation)?

    - by Amumu
    So I heard the positions for designing software and writing spec for developers to implement are higher and getting paid more. I think many companies are using the Software Engineering title to depict the person to implement software, which means using tools and technologies to write the actual code. I know that in order to be a software architecture, one needs to be good at implementation in order to have an architectural overview of a system using a set of specific technologies. This is different than I thought of a Software Engineer. My thinking is similar to the standard of IEEE: A software engineer is an engineer who is capable of going from requirement analysis until the software is deployed, based on the SWEBOK (IEEE). Just look at the table of content. The IEEE even has the certificate for Software Engineering, since ABET (Accreditation Board for Engineering and Technology) seems to not have an official qualification test for Software Engineer (although IEEE is a member of ABET). The two certificates are CSDA and CSDP. I intend to take on these two examination in the future to be qualified as a software engineer, although I am already working as one (Junior position). On a side note on the issues of Software Engineer, you can read the dicussion here: Just a Programmer and Just a Software Engineer. The information of ABET does not accredit Software Engineer is in "Just a Software Engineer". On the other hand, why is Programmer/Softwar Engineer who writes code considered a low level position? Suppose if two people have equal skills after the same years of experience, one becomes a software architect and one keeps focus on implementation aspect of Software Engineering (of course he also has design skill to compose a system, since he's a software engineer as well, but maybe less than the specialized software architect), how comes work from Software Engineer is less complicated than the Software Architect? In order to write great code with turn design into reality, it requires far greater skill than just understanding a particular language and a framework. I don't think the ones who wrote and contributing Linux OS are lower level job and easier than conceptual design and writing spec. Can someone enlighten me?

  • Looking for good Regex book

    - by Cyberherbalist
    I've been trying to get a good grounding with Regular Expressions, and am looking for a single book to do so. I've been going through Amazon.com's listings on this subject, and I've identified a few possibilities, but am unsure which would be best for a C# developer who can write very simple Regexs, but wants to learn more. On a scale of 0-9 where 0 is knowing how to spell "Regex" but nothing else, and 9 where I could write a book on the subject out of my own head, I would place myself at 2. Which of the following would be your choice: Mastering Regular Expressions by Jeffrey E F Friedl Regular Expressions Cookbook by Jan Goyvaerts and Steven Levithan Sams Teach Yourself Regular Expressions in 10 Minutes by Ben Forta Beginning Regular Expressions (Programmer to Programmer) by Andrew Watt Regular Expression Recipes for Windows Developers: A Problem-Solution Approach by Nathan A. Good Regular Expression Recipes: A Problem-Solution Approach by Nathan A. Good Now, according to Amazon, "Regular Expressions Cookbook" (REC) above is rated the highest according to user ratings, but only based on 20 reviews. The first one, "Mastering Regular Expressions" (MRE) is rated second based on 140 reviews. This alone suggests that MRE might be by far the best one. But is it best for a relative beginner? Would I perhaps be better getting "Beginning Regular Expressions" (BRE) instead, to start with? Please help me resolve my confusion!

  • The Low Down Dirty Azure Blues

    - by SGWellens
    Remember the SETI screen savers that used to be on everyone's computer? As far I as know, it was the first bona-fide use of "Cloud" computing…albeit an ad hoc cloud. I still think it was a brilliant leveraging of computing power. My interest in clouds was re-piqued when I went to a technical seminar at the local .Net User Group. The speaker was Mike Benkovitch and he expounded magnificently on the virtues of the Azure platform. Mike always does a good job. One killer reason he gave for cloud computing is instant scalability. Not applicable for most applications, but it is there if needed. I have a bunch of files stored on Microsoft's SkyDrive platform which is cloud storage. It is painfully slow. Accessing a file means going through layers and layers of software, redirections and security. Am I complaining? Hell no! It's free! So my opinions of Cloud Computing are both skeptical and appreciative. What intrigued me at the seminar, in addition to its other features, is that Azure can serve as a web hosting platform. I have a client with an Asp.Net web site I developed who is not happy with the performance of their current hosting service. I checked the cost of Azure and since the site has low bandwidth/space requirements the cost would be competitive with the existing host provider: Azure Pricing Calculator. And, Azure has a three month free trial. Perfect! I could try moving the website and see how it works for free. I went through the signup process. Everything was proceeding fine until I went to the MS SQL database management screen. A popup window informed me that I needed to install Silverlight on my machine. Silverlight? No thanks. Buh-Bye. I half-heartedly found the Azure support button and logged a ticket telling them I didn't want Silverlight on my machine. Within 4 to 6 hours (and a myriad (5) of automated support emails) they sent me a link to a database management page that did not require Silverlight. Thanks! I was able to create a database immediately. One really nice feature was that after creating the database, I was given a list of connection strings. I went to the current host provider, made a backup of the database and saved it to my machine. I attached to the remote database using SQL Server Studio 2012 and looked for the Restore menu item. It was missing. So I tried using the SQL command: RESTORE DATABASE MyDatabase FROM DISK ='C:\temp\MyBackup.bak' Msg 40510, Level 16, State 1, Line 1 Statement 'RESTORE DATABASE' is not supported in this version of SQL Server. Are you kidding me? Why on earth…? This can't be happening! I opened both the source database and destination database in SQL Management Studio. I right clicked the source database, selected "Tasks" and noticed a menu selection called "Deploy Database to SQL Azure" Are you kidding me? Could it be? Oh yes, it be! There was a small problem because the database already existed on the Azure machine, I deployed to a new name, deleted the existing database and renamed the deployed database to what I needed. It was ridiculously easy. Being able to attach SQL Management Studio to remote databases is an awesome but scary feature. You can limit the IP addresses that can access the database which enhances security but when you give people, any people, me included, that much power, one errant mouse click could bring a live system down. My Advice: Tread softly and carry a large backup thumb-drive. Then I created a web site, the URL it returned look something like this: http://MyWebSite.azurewebsites.net/ Azure supports FTP, but I couldn't figure out the settings until I downloaded the publishing profile. It was an XML file that contained the needed information. I still couldn't connect with my FTP client (FileZilla). After about an hour of messing around, I deleted the port number from the FileZilla setup page….and voila, I was in like Flynn.   There are other options of deploying directly from Visual Studio, TFS, etc. but I do not like integrated tools that do things without my asking: It's usually hard to figure out what they did and how to undo it. I uploaded the aspx , cs , webconfig, etc. files. Bu it didn't run. The site I ported was in .NET 3.5. The Azure website configuration page gave me a choice between .NET 2.0 and 4.0. So, I switched to Visual Studio 2010, chose .NET 4.0 and upgraded the site. Of course I have the original version completely backed up and stored in a granite cave beneath the Nevada desert. And I have a backup CD under my pillow. The site uses ReportViewer to generate PDF documents. Of course it was the wrong version. I removed the old references to version 9 and added new references to version 10 (*see note below). Since the DLLs were not on the Azure Server, I uploaded them to the bin directory, crossed my fingers, burned some incense and gave it a try. After some fiddling around it ran. I don't know if I did anything particular to make it work or it just needed time to sort things out. However, one critical feature didn't work: ReportViewer could not programmatically generate PDF documents. I was getting this exception: "An error occurred during local report processing. Parameter is not valid." Rats. I did some searching and found other people were having the same problem, so I added a post saying I was having the same problem: http://social.msdn.microsoft.com/Forums/en-US/windowsazurewebsitespreview/thread/b4a6eb43-0013-435f-9d11-00ee26a8d017 Currently they are looking into this problem and I am waiting for the results. Hence I had the time to write this BLOG entry. How lucky you are. This was the last message I got from the Microsoft person: Hi Steve, Windows Azure Web Sites is a multi-tenant environment. For security issue, we limited some API calls. Unfortunately, some GDI APIS required by the PDF converting function are in this list. We have noticed this issue, and still investigation the best way to go. At this moment, there is no news to share. Sorry about this. Will keep you posted. If I had to guess, I would say they are concerned with people uploading images and doing intensive graphics programming which would hog CPU time.  But that is just a guess. Another problem. While trying to resolve the ReportViewer problem, I tried to write a file to the PDF directory to see if there was a permissions problem with some test code: String MyPath = MapPath(@"~\PDFs\Test.txt"); File.WriteAllText(MyPath, "Hello Azure");     I got this message: Access to the path <my path> is denied. After some research, I understood that since Azure is a cloud based platform, it can't allow web applications to save files to local directories. The application could be moved or replicated as scaling occurs and trying to manage local files would be problematic to say the least. There are other options: Use the Azure APIs to get a path. That way the location of the storage is separated from the application. However, the web site is then tied Azure and can't be moved to another hosting platform. Use the ApplicationData folder (not recommended). Write to BLOB storage. Or, I could try and stream the PDF output directly to the email and not save a file. I'm not going to work on a final solution until the ReportViewer is fixed. I am just sharing some of the things you need to be aware of if you decide to use Azure. I got this information from here. (Note the author of the BLOG added a comment saying he has updated his entry). Is my memory faulty? While getting this BLOG ready, I tried to write the test file again. And it worked. My memory is incorrect, or much more likely, something changed on the server…perhaps while they are trying to get ReportViewer to work. (Anyway, that's my story and I'm sticking to it). *Note: Since Visual Studio 2010 Express doesn't include a Report Editor, I downloaded and installed SQL Server Report Builder 2.0. It is a standalone Report Editor to replace the one not in Visual Studio 2010 Express. I hope someone finds this useful. Steve Wellens CodeProject

  • How to make computer interface with circuit

    - by light.hammer
    I understand that I can build a circuit that will do whatever I like (ex: a simple circuit that will turn on a motor to open the blinds or something), and I can write a program that will automate my computer/mac however I like (ex: open this program at this time, or with this input and create a new file, ect). My question is, how can I interface the two? Is there an easy DIY or cheap commercial (or not cheap but functional) USB plug that will turn on/off from computer commands? I'm basically looking for some sort of on/off switch I can script/applescript. How would you even approach this problem, would I have to write my own driver some where along the way?

  • Creating a JSONP Formatter for ASP.NET Web API

    - by Rick Strahl
    Out of the box ASP.NET WebAPI does not include a JSONP formatter, but it's actually very easy to create a custom formatter that implements this functionality. JSONP is one way to allow Browser based JavaScript client applications to bypass cross-site scripting limitations and serve data from the non-current Web server. AJAX in Web Applications uses the XmlHttp object which by default doesn't allow access to remote domains. There are number of ways around this limitation <script> tag loading and JSONP is one of the easiest and semi-official ways that you can do this. JSONP works by combining JSON data and wrapping it into a function call that is executed when the JSONP data is returned. If you use a tool like jQUery it's extremely easy to access JSONP content. Imagine that you have a URL like this: http://RemoteDomain/aspnetWebApi/albums which on an HTTP GET serves some data - in this case an array of record albums. This URL is always directly accessible from an AJAX request if the URL is on the same domain as the parent request. However, if that URL lives on a separate server it won't be easily accessible to an AJAX request. Now, if  the server can serve up JSONP this data can be accessed cross domain from a browser client. Using jQuery it's really easy to retrieve the same data with JSONP:function getAlbums() { $.getJSON("http://remotedomain/aspnetWebApi/albums?callback=?",null, function (albums) { alert(albums.length); }); } The resulting callback the same as if the call was to a local server when the data is returned. jQuery deserializes the data and feeds it into the method. Here the array is received and I simply echo back the number of items returned. From here your app is ready to use the data as needed. This all works fine - as long as the server can serve the data with JSONP. What does JSONP look like? JSONP is a pretty simple 'protocol'. All it does is wrap a JSON response with a JavaScript function call. The above result from the JSONP call looks like this:Query17103401925975181569_1333408916499( [{"Id":"34043957","AlbumName":"Dirty Deeds Done Dirt Cheap",…},{…}] ) The way JSONP works is that the client (jQuery in this case) sends of the request, receives the response and evals it. The eval basically executes the function and deserializes the JSON inside of the function. It's actually a little more complex for the framework that does this, but that's the gist of what happens. JSONP works by executing the code that gets returned from the JSONP call. JSONP and ASP.NET Web API As mentioned previously, JSONP support is not natively in the box with ASP.NET Web API. But it's pretty easy to create and plug-in a custom formatter that provides this functionality. The following code is based on Christian Weyers example but has been updated to the latest Web API CodePlex bits, which changes the implementation a bit due to the way dependent objects are exposed differently in the latest builds. Here's the code:  using System; using System.IO; using System.Net; using System.Net.Http.Formatting; using System.Net.Http.Headers; using System.Threading.Tasks; using System.Web; using System.Net.Http; namespace Westwind.Web.WebApi { /// <summary> /// Handles JsonP requests when requests are fired with /// text/javascript or application/json and contain /// a callback= (configurable) query string parameter /// /// Based on Christian Weyers implementation /// https://github.com/thinktecture/Thinktecture.Web.Http/blob/master/Thinktecture.Web.Http/Formatters/JsonpFormatter.cs /// </summary> public class JsonpFormatter : JsonMediaTypeFormatter { public JsonpFormatter() { SupportedMediaTypes.Add(new MediaTypeHeaderValue("application/json")); SupportedMediaTypes.Add(new MediaTypeHeaderValue("text/javascript")); //MediaTypeMappings.Add(new UriPathExtensionMapping("jsonp", "application/json")); JsonpParameterName = "callback"; } /// <summary> /// Name of the query string parameter to look for /// the jsonp function name /// </summary> public string JsonpParameterName {get; set; } /// <summary> /// Captured name of the Jsonp function that the JSON call /// is wrapped in. Set in GetPerRequestFormatter Instance /// </summary> private string JsonpCallbackFunction; public override bool CanWriteType(Type type) { return true; } /// <summary> /// Override this method to capture the Request object /// and look for the query string parameter and /// create a new instance of this formatter. /// /// This is the only place in a formatter where the /// Request object is available. /// </summary> /// <param name="type"></param> /// <param name="request"></param> /// <param name="mediaType"></param> /// <returns></returns> public override MediaTypeFormatter GetPerRequestFormatterInstance(Type type, HttpRequestMessage request, MediaTypeHeaderValue mediaType) { var formatter = new JsonpFormatter() { JsonpCallbackFunction = GetJsonCallbackFunction(request) }; return formatter; } /// <summary> /// Override to wrap existing JSON result with the /// JSONP function call /// </summary> /// <param name="type"></param> /// <param name="value"></param> /// <param name="stream"></param> /// <param name="contentHeaders"></param> /// <param name="transportContext"></param> /// <returns></returns> public override Task WriteToStreamAsync(Type type, object value, Stream stream, HttpContentHeaders contentHeaders, TransportContext transportContext) { if (!string.IsNullOrEmpty(JsonpCallbackFunction)) { return Task.Factory.StartNew(() => { var writer = new StreamWriter(stream); writer.Write( JsonpCallbackFunction + "("); writer.Flush(); base.WriteToStreamAsync(type, value, stream, contentHeaders, transportContext).Wait(); writer.Write(")"); writer.Flush(); }); } else { return base.WriteToStreamAsync(type, value, stream, contentHeaders, transportContext); } } /// <summary> /// Retrieves the Jsonp Callback function /// from the query string /// </summary> /// <returns></returns> private string GetJsonCallbackFunction(HttpRequestMessage request) { if (request.Method != HttpMethod.Get) return null; var query = HttpUtility.ParseQueryString(request.RequestUri.Query); var queryVal = query[this.JsonpParameterName]; if (string.IsNullOrEmpty(queryVal)) return null; return queryVal; } } } Note again that this code will not work with the Beta bits of Web API - it works only with post beta bits from CodePlex and hopefully this will continue to work until RTM :-) This code is a bit different from Christians original code as the API has changed. The biggest change is that the Read/Write functions no longer receive a global context object that gives access to the Request and Response objects as the older bits did. Instead you now have to override the GetPerRequestFormatterInstance() method, which receives the Request as a parameter. You can capture the Request there, or use the request to pick up the values you need and store them on the formatter. Note that I also have to create a new instance of the formatter since I'm storing request specific state on the instance (information whether the callback= querystring is present) so I return a new instance of this formatter. Other than that the code should be straight forward: The code basically writes out the function pre- and post-amble and the defers to the base stream to retrieve the JSON to wrap the function call into. The code uses the Async APIs to write this data out (this will take some getting used to seeing all over the place for me). Hooking up the JsonpFormatter Once you've created a formatter, it has to be added to the request processing sequence by adding it to the formatter collection. Web API is configured via the static GlobalConfiguration object.  protected void Application_Start(object sender, EventArgs e) { // Verb Routing RouteTable.Routes.MapHttpRoute( name: "AlbumsVerbs", routeTemplate: "albums/{title}", defaults: new { title = RouteParameter.Optional, controller = "AlbumApi" } ); GlobalConfiguration .Configuration .Formatters .Insert(0, new Westwind.Web.WebApi.JsonpFormatter()); }   That's all it takes. Note that I added the formatter at the top of the list of formatters, rather than adding it to the end which is required. The JSONP formatter needs to fire before any other JSON formatter since it relies on the JSON formatter to encode the actual JSON data. If you reverse the order the JSONP output never shows up. So, in general when adding new formatters also try to be aware of the order of the formatters as they are added.

  • How do I get a Dane-Elec mp3/mp4 player working?

    - by user40432
    My MP3/MP4 does not plug-in and play and therefore I can not transfer any file to the MP3/MP4 dane-elec music my touch or only dane-elec with 8 gb in memory and perhapses model zt1 with radio,..and microsdhc card slot following the above link the mp3/mp4 is there and it is MP3 Player: TOUCH MY MUSIC and the complete information is on this site http://www.danedigital.com/8-Music-Media-Players/2-music-touch.html as the Technical Specifications MP3 Player: TOUCH MY MUSIC The Mp4 player has a very classy. It allows its users to play music and view photos and video. His fluent interface, its touch-pad, his radio and RDS Micro SDHC reader makes him a very complete device will become the ideal musical companion. ubuntu i am with is ubuntu 11.10 kernel 3.0.0-14-generic the latest I tried to install many applications but nothing worked. With disk utility I can see that Ubuntu can recognize something, that as a peripheral device named rockchip usbdisk user and rockchip usbdisk sd, and i can plug and play other devices, and only this mp3/mp4 do not connect to the computer with ubuntu and the device as no problem working disconnected to computer I try to see if work on Windows and it does! I can see the device and transfer files to the MP3/MP4 dane-elec folder device and use FAT32. So why can not do on Ubuntu!? What can I do and why does not work on Ubuntu? What is wrong with it?

  • C#.NET vs VB.NET, Which language is better?

    Features I cannot say any language good or bad as long as it's compiler can produce MSIL can run under .NET CLR. If someone says C# has more futures, you can understand that those new features are of C# compiler but not .NET, because if C# has a specific future then CLR cannot understand them. So the new features of C# will have to convert to the code understood by CLR eventually. that means the new features are developed for C# compiler basically to facilitates the developer to write their code in better way. so that means no difference in feature list between C# and VB.NET if you think in CLR perspective. Ease of writing Code I feel writing code in C# is easy, because my background is C and C++, Java, syntaxes very are similar. I assume most developers feel the same. Readability But some people say VB.NET code most readable for the members who are from non technical background, because keywords are generally in English rather special charectors. No of Projects in Market I assume 80 percent of market uses C# in their .NET development. for example in my company many projects are there .nET and all are using C#. Productivity & Experience though the feature list is same, generally developers wants to write code in their familiar languages. because it increase the productivity. Hope this helps to choose the language which suits for you. span.fullpost {display:none;}

  • Writing algorithm on 2D data set in plain english

    - by Alexandre P. Levasseur
    I have started an introductory Java class and the material is absolutely horrendous and I have to get excellent grades to be accepted into the master's degree, hence my very beginner question: In my assignment I have to write algorithms (no pseudo-code yet) to solve a board game (Sudoku). Essentially, the notes say that an algorithm is specification of the input(s), the output(s) and the treatments applied to the input to get the output. My question lies on the wording of algorithms because I could probably code it but I can't seem to put it on paper in a coherent way. The game has a 9x9 board and one of the algorithms to write has to find the solution by looking at 3 squares (either horizontal or vertical) and see if one of the three sub-squares match the number you are looking for. If none match then the number you are looking to place is in one of the other 2 set of 3 sub-squares (see image to get a better idea). I really can't get my head around how to formulate the solution into the terms described above or maybe it's just too simple, here's what I was thinking: Input: A 2-dimensional set of data of size 9 by 9 to be solved and a number to search for. Ouput: A 2-dimensional set of data of size 9 by 9 either solved or partially solved. Treatment: Scan each set of 3x9 and 9x3 squares. For each line or column of a 3x3 square check if the number matches a line (or column). If it does then move to the next line (or column). If not then proceed to the next 3x3 square in the same line (or column). Rinse and repeat. Does that make sense as an algorithm written in plain english ? I'm not looking for an answer to the algorithm per se but rather on the formulation of algorithms in plain english.

  • GLSL compile error when accessing an array with compile-time constant index

    - by Benlitz
    I have this shader that works well on my computer (using an ATI HD 5700). I have a loop iterating between two constant values, which is, afaik, acceptable in a glsl shader. I write stuff in two arrays in this loop. #define NB_POINT_LIGHT 2 ... varying vec3 vVertToLight[NB_POINT_LIGHT]; varying vec3 vVertToLightWS[NB_POINT_LIGHT]; ... void main() { ... for (int i = 0; i < NB_POINT_LIGHT; ++i) { if (bPointLightUse[i]) { vVertToLight[i] = ConvertToTangentSpace(ShPointLightData[i].Position - WorldPos.xyz); vVertToLightWS[i] = ShPointLightData[i].Position - WorldPos.xyz; } } ... } I tried my program on another computer equipped with an nVidia GTX 560 Ti, and it fails to compile my shader. I get the following errors (94 and 95 are the lines of the two affectations) when calling glLinkProgram: Vertex info ----------- 0(94) : error C5025: lvalue in assignment too complex 0(95) : error C5025: lvalue in assignment too complex I think my code is valid, I don't know if this comes from a compiler bug, a conversion of my shader to another format from the compiler (nvidia looks to convert it to CG), or if I just missed something. I already tried to remove the if (bPointLightUse[i]) statement and I still have the same error. However, if I just write this: vVertToLight[0] = ConvertToTangentSpace(ShPointLightData[0].Position - WorldPos.xyz); vVertToLightWS[0] = ShPointLightData[0].Position - WorldPos.xyz; vVertToLight[1] = ConvertToTangentSpace(ShPointLightData[1].Position - WorldPos.xyz); vVertToLightWS[1] = ShPointLightData[1].Position - WorldPos.xyz; Then I don't have the error anymore, but it's really unconvenient so I would prefer to keep something loop-based. Here is the more detailled config that works: Vendor: ATI Technologies Inc. Renderer: ATI Radeon HD 5700 Series Version: 4.1.10750 Compatibility Profile Context Shading Language version: 4.10 And here is the more detailed config that doesn't work (should also be compatibility profile, although not indicated): Vendor: NVIDIA Corporation Renderer: GeForce GTX 560 Ti/PCI/SSE2 Version: 4.1.0 Shading Language version: 4.10 NVIDIA via Cg compiler

  • Inside Sweden’s Nuclear Bunker Turned Data Center

    - by Jason Fitzpatrick
    A data center inside a decommissioned nuclear bunker is interesting enough, but one that looks as futuristic and awesome as the center under Stockholm begs to be seen. A hundred feet under the city of Stockholm is a decommissioned nuclear bunker that the government had previously leased out intermittently for various events, but it was never put to serious or extended use. Not until, that is,  Jon Karlung discovered the location and brought his vision of an ultra-modern, stylish, and secure data center to life. The passage from Wired’s write up of their photo tour that best encapsulates the feel of the bunker is: Most often data centers are built in boxy warehouses, so Bahnhof stands out as perhaps the world’s most stylish. In fact, it inspired Cisco IT Architect Douglas Alger to write a book on the world’s best-looking data centers. ”The idea that people were sitting in a design meeting and said, ‘what we need for our data center is waterfalls,’ that must have been a very fascinating discussion,” Alger says. Hit up the link below for the full photo tour. Deep Inside the James Bond Villain Lair That Actually Exists [Wired] Why Does 64-Bit Windows Need a Separate “Program Files (x86)” Folder?

  • Set umask, set permissions, and set ACL, but SAMBA isn't using those?

    - by Kris Anderson
    I'm running on Ubuntu Server 12.04. I have a folder called Music and I want the default folder permissions to be 775 and the default file to then be 664. I set the default permissions on the Music folder to be 775. I configured ACL to use these default permissions as well: file: Music owner: kris group: kris flags: ss- user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:other::r-x I also changed the default umask for my user account, kris, to 002 in .profile. Shouldn't and new file/folder now use those permissions when writing to the Samba share? ACL should work with Samba from what I can gather. Currently, if I write to that folder using my mac, folders are getting 755 and files 644. I have another app on my mac called GoodSync which which is able to sync a local directory on my mac to a network samba share, but those permissions are even worse. files are being written as 700 using that program. So it looks like Samba is allowing the host/program to determine the folder/file permissions. What changes do I need to make to force the permissions I want regardless of what the host tries to write on the server?

  • KVM slow guest i/o

    - by Akarot
    Host: Debian 6.0 (squeeze) with qemu-kvm and libvirt from squeeze-backports ii qemu-kvm 1.0+dfsg-8~bpo60+1 ii libvirt-bin 0.9.8-2~bpo60+2 Has 3TB sata drives with software raid and lvm. It has a sequential write speed of ~140MB/s measured with dd bs=1M count=512 if=/dev/zero of=test conv=fdatasync Elevator set to cfq Guest Debian 6.0 (squeeze) Uses LVM as storage. Drivers are virtio and cache='none' Sequential write speed is considerably slower with only 25-50MB/s Elevator set to noop I'm kind of running out of ideas for further tweaks but I'm sure that I/O speed should be much faster because many people are reporting almost native performance with lvm.

  • NEC uPD720200 USB 3.0 not working on Ubuntu 12.04

    - by Jagged
    I've recently installed Ubuntu 12.04 64-bit on a HP Envy 15 1104tx. Most stuff appears to be working fine with the exception of the two USB3 ports (USB2 port works fine). I've read a lot of articles but so far have not been able to find a solution. I've tried adding 'pci=nomsi' to '/etc/default/grub' but this made no difference. Some articles suggest booting into Windows and upgrading the firmware on the uPD720200. Any body had any experience of this? Is there a way I can checked the firmware version of the NEC uPD720200 in Linux to see if there is an update available? Any help appreciated. uname -a: Linux HP-ENVY-15-1104tx 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux lshw: hp-envy-15-1104tx description: Notebook
