• How to understand the LSI HBA connector specs?

  - by Sandra

  When reading the specifications for the LSi SAS 9206-16e HBA, it says Storage Connectivity; Data Transfer Rates * 16 ports; 6Gb/s SAS 2.1 compliant SAS Bandwidth * Half Duplex 2400MB/s, x4, 6Gb/s SAS lanes Port Configurations * 16 ea, x1 ports (individual drives) * 4 ea, x4 wide ports * 2ea, x8 wide ports Connectors * Four (x4) mini-SAS HD external connectors (SFF8644) So there are 4 physical connectors. Question What is the bandwidth for each of the connectors? I would be temped to say 6Gb/s * 4, but then it mentions the "Port Configurations" and 2ea, 4ea, 16ea, which I don't understand what is. Does this mean, that the 4 physical connectors are not identical?

• .NET or Windows Synchronization Primitives Performance Specifications

  - by ovanes

  Hello *, I am currently writing a scientific article, where I need to be very exact with citation. Can someone point me to either MSDN, MSDN article, some published article source or a book, where I can find performance comparison of Windows or .NET Synchronization primitives. I know that these are in the descending performance order: Interlocked API, Critical Section, .NET lock-statement, Monitor, Mutex, EventWaitHandle, Semaphore. Many Thanks, Ovanes P.S. I found a great book: Concurrent Programming on Windows by Joe Duffy. This book is written by one of the head concurrency developers for .NET Framework and is simply brilliant with lots of explanations, how things work or were implemented.

• Any specifications/docs around optimization of Google Apps Script, to avoid timeouts and "hangs"

  - by BruceM

  From my experience so far, it seems that if you write a script that makes lots of expensive calls close together, the functionality just "hangs", or you get inconsistent responses, and have to refresh the browser because sheets stop updating etc. Are there any docs or specs that clarify this, as releasing an app fr real-world use is not possible if users can expect it to work most of the time, and produce random results every now and then...

• Functional Specifications vs. Requirements Document

  - by KP

  Guys, Currently in my comp., there are some changes going on regarding project documentation. There is a LOT of time and effort spent on discussing functional specs vs. requirements doc. However, I don't think anyone here understands the reason why you would use one over the other. Therefore, I don't understand the difference myself. Can someone shed some light on this matter plz? If you have links to articles, blog posts, etc. that would be helpful too. Thanks

• References for better performance of newer JSF specifications

  - by Pentius

  Dear fellows, I'm looking for a reference to cite, which states that JSF 1.2 performs better than JSF 1.1. Or JSF 2.0 over JSF 1.2 respectively. I'm quite sure that I've read something like this before but can't find it anymore. Maybe you can help. Or is this mischief and there are no official statements regarding the performance?

• Why is there no .NET Community Process?

  - by michielvoo

  I was doing some research into general topics of software engineering and I came across the Java Community Process website: The JCP is the mechanism for developing standard technical specifications for Java technology. Anyone can register for the site and participate in reviewing and providing feedback for the Java Specification Requests (JSRs), and anyone can sign up to become a JCP Member and then participate on the Expert Group of a JSR or even submit their own JSR Proposal. Seems like a good idea to me, and there are lots of very well written specifications and reference implementations on the JCP website. So why is there no .NET Community Process? Is that something that Microsoft could or should start? Maybe they could install it on Codeplex.net and hand over the keys to the community.

• scrum and specifications

  - by zachary

  So we start Scrum today and start going over story points estimates. The first story that comes up is a new screen that needs to be developed. It has 1 sentence to describe the screen and 3 user acceptance tests. This starts a fight between the development team and the product owner. Product owner says that stories do not need to be speced out and they will just be fleshed out during the sprint. We say that the story needs to be completely speced out for the sprint. But now I am starting to be unsure about who is right.... Any good articles on this that I can send to the team about how defined a user story has to be?

• Convince teammates to follow standards

  - by folone

  There's always one or two guys, who think, they are great programmers, and they don't need any literature/specifications/etc. They usually write awful code, that makes you want to hurt them. They catch and suppress Throwable's, return null's, concatenate String's in large loops, do other stupid stuff. So the question is — How do I make such a person follow best practices and specifications? He does not listen (cause he's the best programmer), team lead does not give a damn ("It actually works, so why changing it?.."), and I'm actually tired of rewriting that awful code on my own. What do I do? What would you do?

• Erlang Types Specifications

  - by Chang

  I recently read the source code of couch-db, I find this type definition which i don't understand: -type branch() :: {Key::term(), Value::term(), Tree::term()}. -type path() :: {Start::pos_integer(), branch()}. -type tree() :: [branch()]. I did read Erlang doc, But what is the meaning of Start, Key, Value and Tree? From what i understand, they are Erlang variables! I didn't find any information about this in Erlang doc.

• In which document do file specifications belong?

  - by Andrew

  In which document would a file specification belong? Perhaps this file is used as an input to a third-party system. Would it belong in its own document? Or would it be better to put it in the functional or design spec? Or somewhere else? When I say file specification, I mean a description of what format the file is (CSV, fixed width, etc), columns, data types, etc. Also, where should you document how the file is generated? i.e. business rules/algorithms which are used to generate the file.

• Specification Pattern vs Spec in BDD

  - by cadmium

  I'm trying to explore Behavior Driven Design and Domain Driven Design. I'm getting that written specifications drive the tests in BDD, but also that business logic can be encapsulated using the specification pattern for re-use in domain objects and repositories, etc. Are these basically the same concept just used in different ways, used in conjunction together, or am I completely confusing the concepts? Please shed some light, if possible.

• determine if intersection of a set with conjunction of two other sets is empty

  - by koen

  For any three given sets A, B and C: is there a way to determine (programmatically) whether there is an element of A that is part of the conjunction of B and C? example: A: all numbers greater than 3 B: all numbers lesser than 7 C: all numbers that equal 5 In this case there is an element in set A, being the number 5, that fits. I'm implementing this as specifications, so this numerical range is just an example. A, B, C could be anything.

• Can you unit / integration tests without creating test codes?

  - by geff_chang

  In our project, test procedures and expected test results (test specifications) are created in a document. Then, we perform testing on a built product / release. Here, no test codes nor test tools are involved. Is this acceptable for unit / integration testing?

• What's the maximum safe temperature for a HD Radeon 6870?

  - by Adrian Grigore

  I'm running a passively cooled HD Radeon 6870 in my PC. While using 3D Acceleration, the temperature climbs up to 95 degrees Celsius according to SpeedFan. It seems a bit hot, but on the other hand I've seen other GPUs being specified to run up to 120 Degrees Celsius. The system is very stable, but Battlefield 3 crashes every few hours or so. On the other hand it might be the game's fault and not related to the GPU temperature at all. Does anyone know where I can find some manufacturer specs on the maximum allowed temperature for this GPU? Thanks, Adrian

• Suggestions for SOHO networking gear

  - by jakemcgraw

  I'm a software developer in my day to day job but have landed a contract position to spec out and install the computer equipment for a small office. Ease of use (easy installation, low maintenance and good support) is priority number one, it supersedes price by a wide margin. The installation we had in mind would support up to ten workstations. I was originally going to go with Netgear hardware for firewall, switch duties: Firewall: NETGEAR UTM25-100NAS Switch:NETGEAR GS724T but have been told Sonicwall firewalls are easier to configure. So, sysadmins, if ease of use was priority number one, what hardware would you purchase for firewall, switch duties?

• What’s the Minimum System Spec Recommended For Developer Laptop

  - by DaveDev

  I'll be regularly running Visual Studio 2010 Professional, SQLServer Express, Office and at least 1 virtual environment running a Linux Distro. I want the machine to be snappy and responsive even when doing a reasonable amount of Development work. I want to spend what it takes for this, but I don't want to go overboard spending more than I need to. I won't be playing many games or graphics processing so i won't need a monster of a machine. Any recommendations?

• Intel Xeon vt-d query

  - by deploymonkey

  Does Xeon westmere ep (xeon 56xx series) have vt-d (=iommy / direct io) or does intel TXT (Intel® Trusted Execution Technology) include vt-d? I'm at a loss. I've been researching current processors for an important project for some time now. I need to know, if the xeon 5600s (Westmere EP) include vt-d (iommu/directed io/pci passing) because the system will run virtualized guests. This enables direct hardware access eg. pci passthrough, in xen for example. It seems that the 5600s TXT should incorporate vt-d and that xeon 5600s should include vt-d as they are ramped up 5500s, but there is no conclusive answer anywhere. Intel's processor comparison only states that 5500s have vt-d and no TXT and 5600s have no vt-d but TXT. I'd be really grateful if anybody could clear this up and possibly even provide a citation. Thanks a lot.

• How to document mail setup after hand-over.

  - by BradyKelly

  I've just moved a client's email services over from my host to Google Apps. I would like to hand over a document providing all they (or their agent) need should I not be available etc. How are such documents normally structured, and what level of detail should they contain? I know user names and passwords are essential, and instructions on how to manage domains on Google Apps are over the top, but what is a commonly used middle ground?

• Operating altitude for a MacBook Pro?

  - by Jeff Meatball Yang

  I saw on the Apple website that the MacBook pro has a maximum operating altitude. Maximum operating altitude: 10,000 feet Does this mean that I should not use it on a plane? Or is this just a slick way for Apple to say, "It's not our fault if you use it on a plane and it breaks."

• Need advise on choosing aws EC2

  - by Mayank

  I'm planning to host a website where in the first phase I would target 30,000 users. It is in php and runs on Apache server. I'm assuming 8,000 users can be online in worst case scenario and 1000 of them will be uploading photographs. A photograph will be resized to around 1MB at client side and one HTTP request is uploading only one photograph. My plan: 2 Small EC2 instances to run Apache httpd 2 Small EC2 instances to DB (Postgresql). I to write data and other its read replica. EBS volumes for DBs Last, Amazon S3 for uploaded photographs. My question here Is Small EC2 instance more than what I require. I mean should I go for micro Is 8000 simultaneous user a right no. (to decide what EC2 instance to choose) for a new website Or should I go for Small instance so to make it capable of spikes
