• Why not write all tests at once when doing TDD? [closed]

  - by RichK

  Possible Duplicate: Why not write all tests at once when doing TDD? The Red - Green - Refactor cycle for TDD is well established and accepted. We write one failing unit test and make it pass as simply as possible. What are the benefits to this approach over writing many failing unit tests for a class and make them all pass in one go. The test suite still protects you against writing incorrect code or making mistakes in the refactoring stage, and code coverage should be just as high, so what's the harm? Sometimes it's easier to write all the tests first as a form of 'brain dump' to quickly write down all the expected behavior in one go.

• Azure Florida Association: Modern Architecture for Elastic Azure Applications

  - by Herve Roggero

  Join us on November 28th at 7PM, US Eastern Time, to hear Zachary Gramana talk about elastic scale on Windows Azure. REGISTER HERE: https://www3.gotomeeting.com/register/657038102 Description: Building horizontally scalable applications can be challenging. If you face the need to rapidly scale or adjust to high load variations, then you are left with little choice. Azure provides a fantastic platform for building elastic applications. Combined with recent advances in browser capabilities, some older architectural patterns have become relevant again. We will dust off one of them, the client-server architecture, and show how we can use its modern incarnation to bypass a class of problems normally encountered with distributed ASP.NET applications.

• Why do exclusively outsourcing projects as a company?

  - by user19833

  A prospective employer told me they took a company level decision to only do outsourcing projects. I do not understand why did they take such a decision and the guy I talked to did not elaborate. He further said only that "their intention is to build software components". Since they are growing quite fast and reached around 300 employees, shouldn't they be at least open to the possibility of having a project of their own, maybe? All other companies I've had contact with were at least open to have one in the future.. I talked to a few of their employees and some are working in parallel on more than 2 outsourced projects (dividing time something like 4 + 4 hours / day). It seemed like a lot of projects with a period of a few months, maybe half an year come and go... Why would a company choose to provide only outsourcing services like that? How does it work to keep hundreds of people on outsourced projects with a seemingly high project turnover rate?

• DotNetNuke 5.4.2 Released

  I am pleased to announce the release of DotNetNuke 5.4.2. 5.4.2 is a monthly stabilization release which addresses a couple dozen issues with the 5.4 release. Because of the 5.4.1 release, the 5.4.2 release cycle was shortened which meant that a few high profile issues were not able to make the cutoff for this release. We expect to address those issues in the 5.4.3 release due out in June. This release also includes numerous code contributions and bug fixes submitted by the community. We will be...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

• After 10.10 -> 11.04 upgrade, can only login via Classic (No Effects)

  - by Ryan P.

  Yesterday I upgraded from 10.10 to 11.04, everything seemed to go okay until immediately after login: the desktop goes into a "corrupted" looking state (similar to having too high resolution set). I can see some kind of movement by moving the mouse around/right clicking, and can enter text terminals via ctrl + alt + f1 It does this in both plain "Ubuntu" and "Ubuntu Classic", and only seems to login/startup properly with Ubuntu Classic (No Effects). I have checked my video card (Radeon X600) and run the unity support test which passes with all "yes" results (Unity supported: yes): /usr/lib/nux/unity_support_test -p I have tried re-installing my Ubuntu desktop: rm -rf .gnome .gnome2 .gconf .gconfd .metacity sudo apt-get remove ubuntu-desktop sudo apt-get install ubuntu-desktop With no success. I can workaround for now with Classic (No Effects), but I'd really like to find the root problem. Any suggestions on what else to try would be appreciated!

• What percentage should a consulting company take off the top of your pay?

  - by JasonStoltz

  Let's say that, hypothetically, a programmer is being paid $40 / hour for a 6 month contract, through a contracting agency. That contracting agency is being paid $85 / hour for every hour that programmer works by the client. So the programmer only actually takes home 47% of what the client is paying per hour. Is this normal, or is the percentage unusually low? Other things to consider: The consulting agency isn't paying benefits P.S (If this is normal, I'd also be curious what the justification would be to take that high of a percentage. And if it is NOT normal, what would be a normal percentage?)

• Check if the vector is behind another or maybe opposite directions?

  - by Gilson

  I'm doing a network game and on the client side, i interpolate the client position with the server sent extrapolated position. The client has its own physics simulation wich is corrected by the server in steps. The problem is when it laggs and i 'kick' the ball, the server gets a delayed message and sends me the position backwards of the client position wich makes the ball goes back and forth. I want to ignore those and maybe compensate that on the server, not sure though. The problem is the clock difference on those case are 0.07ms or 0.10 ms wich isn't that high to ignore the message i guess. When i get the server position, i extrapolate with the clock interval * serverBallVelocity Can i check if my new ball server position is behind my actual ball vector position? I tried to use the dot product after normalized the two vectors to check if they are opposite but it ain't working properly. Any suggestions on checking that?

• BCM4313 Wireless on Ubuntu Server 12.04

  - by KJ Tsanaktsidis

  I'm trying to run an old netbook with Broadcom BCM4313 wireless as a print server with Ubuntu Server 12.04. Setting up the wireless without the GUI, however, is proving problematic. I do think however I've narrowed down the problem. I've tried both the wl driver (from bcmwl-kernel-source) as well as the (included) brcmsmac driver. With both of them, when I issue the command iwlist wlan0 scanning (eth1 for wl), I only see neighbouring networks- not my own. I believe this might be because my networks are n-only, but my neighbouring networks are mixed mode (I suspect this because the output of iwlist wlan0 scanning shows "Bit Rates" only as high as 54 Mb/s). Any ideas how to go about getting this thing to connect?

• Handling (many) multiple projects in Git in an enterprise environment

  - by Michael K

  One of the advantages of older version control systems such as CVS and SVN in enterprise development is that anyone can connect to source control and see all the projects that the company has. This can make it easier to get a high level view of what kid of development is happening outside your sprint and also keeps everything in one place and easy to find. However, distributed version control systems (Git, specifically) use the repository as their base unit. They work best with one project (or several closely related projects) per repository. This makes repository management more difficult in most enterprise environments where it is not unusual to have more than 25-50 projects to support. As far as I have been able to determine, you have to keep a list somewhere else of all the repos you have. There is software available, like GitHub, that help, but that still is an extra step beyond a single connection string and listing the contents of the repository. What is the best way to deal with the complexity of multiple repositories?

• How to recover my inclusion in google results after being penalized for receiving comment spam?

  - by UXdesigner

  My website had very high search engine results, especially in Google. But I left the website for a couple of months and didn't notice the comments were full of SPAM, about 20k comments of SPAM. Then i checked my google results and I'm out of google ! After years of having good results, no spam, how can I now recover from that? The spam problem has been solved completely. No more spam, and the website is very legit and very nice. Well, at least I think I was penalized, I don't see any other reason.

• Flash audio problem; redirecting to Pulse?

  - by Makaze

  I am having a problem where the sound on flash objects other than YouTube videos are giving a strange distortion. It has a high pitched pulse sound every second or less that resembles skips on a record. I have no idea what the problem is or how to fix it. Does anyone have an idea what I could do to fix this? I am running Xubuntu 11.10. I think I might have redirected everything to pulse using a config file but I cannot seem to find it anywhere. It used the lines 'type pulse' in it. If anyone knows what I am talking about and how to find that file or whether or not it has any relevance I would greatly appreciate it.

• Calculate initial velocity of a 3d vector-based projectile

  - by Frotty

  Okay, so I got a Projectile with 2 Vectors, position and velocity. I now want to calculate the initial velocity for it in order to reach a specific point on the map. Or actually, how high has the start z-velocity to be (because x and y are probably defined by a speed variable) in order for the projectile to hit the marked position. The projectile is influenced by a constant gravity vector. All calculations are done 32 times per second. I want this, because I don't want to use a parabola function, so the projectile can still be influenced by other sources, simply adding some velocity. I didn't really find anything referring to that topic and would be glad for every helping answer, Thanks.

• Does Google counts backlinks from homepage to inside pages?

  - by SharkTheDark

  I have a site with good PR and my inside pages are getting increase of PR, but they don't have links pointing to them, only from my homepage. Does that means that Google counts ALL links on my homepage, including links to inside pages? Does it calculate inside pages PR with one coming from my domain, my homepage, too? Also, if inside pages that got high PR from homepage have link back to homepage, will that increase homepage PR additionally, since those links should count too? By Google PR algorithm formula, by calculations on Wikipedia and Stanford PR algorithm explanation ( which is originally developed by ) it counts those links, and also it counts after-increase backlink again, making few times circle ( it stops because of d ( 0.85 ) factor. ), but it counts them. Does anyone know is this correct?

• Performance impact of the new mtmalloc memory allocator

  - by nospam(at)example.com (Joerg Moellenkamp)

  I wrote at a number of occasions (here or here), that it could be really beneficial to use a different memory allocator for highly-threaded workloads, as the standard allocator is well ... the standard, however not very effective as soon as many threads comes into play. I didn't wrote about this as it was in my phase of silence but there was some change in the allocator area, Solaris 10 got a revamped mtmalloc allocator in version Solaris 10 08/11 (as described in "libmtmalloc Improvements"). The new memory allocator was introduced to Solaris development by the PSARC case 2010/212. But what's the effect of this new allocator and how does it works? Rickey C. Weisner wrote a nice article with "How Memory Allocation Affects Performance in Multithreaded Programs" explaining the inner mechanism of various allocators but he also publishes test results comparing Hoard, mtmalloc, umem, new mtmalloc and the libc malloc. Really interesting read and a must for people running applications on servers with a high number of threads.

• READ_ME_FIRST: What Do I Do All of Those SPARC Threads?

  - by user12608550

  New Oracle Technical White Paper: READ_ME_FIRST: What Do I Do All of Those SPARC Threads? Executive Overview With an amazing 1,536 threads in an Oracle M5-32 system, the number of threads in a single system has never been so high. This offers a tremendous processing capacity, but one may wonder how to make optimal use of all these resources. In this technical white paper, we explain how the heavily threaded Oracle T5 and M5 servers can be deployed to efficiently consolidate and manage workloads using virtualization through Oracle Solaris Zones, Oracle VM Server for SPARC, and Oracle Enterprise Manager Ops Center, as well as how to improve the performance of a single application through multi-threading.

• Game Development Resources? [closed]

  - by stas

  I want to make an iPhone game and I was wondering if somebody could point me to some resources. Before you rage and close this, I am not looking for just a tutorial on programming, I could just google that. I need to find a tutorial on how to actually make a game, as in how to organize your code, what type of methods to run in separate threads, how to manage these threads in a game, etc. I already know everything I need; I can write a physics engine from scratch, I can write a 3D graphics pipeline from scratch, and so on. What I cannot figure out is how to combine all of this knowledge into correctly and efficiently making a game. Obviously for this one would probably go to college, but seeing as I am still in high school, that is not an option. If anyone would know some tutorials or resources, any pointers would be appreciated.

• How to get familiar with "what happens underneath of Java"?

  - by FidEliO

  I did not study CS nor IT. I just became a developer, now working with Java. Actually, since I now work with a big company writing high-scalable web applications, I think I need to be better with details. I have no understanding of what happens underneath of Java. Java Performance, Server-Side Java might be the buzz words?!! I am very poor with those more of low-level details but I do not know where to look honestly. I started looking for some keywords in Amazon, ended up reading books like "pragmatic programmer", "clean code", "code complete" which IMO they are not what I am looking for. Could you please give me some learning resources (books, articles, blog posts, online trainings) for this matter? I also read this post as well: Approaching Java/JVM internals But I think I need a pre-step before jumping into the OpenJDK, right?!

• Unable to empty the rubbish bin

  When I attempt to empty the rubbish bin the preparing window opens but nothing happens. In testing I tried to delete 1 file from the rubbish bin and received a time-out error. No files are removed from the rubbish bin after this. I have added a screen shot that includes a display of system monitor that shows high CPU usage for trash and Nautilus; not sure whether it is related. Click for a full-resolution image. Also, on a separated note, Bleachbit was also freezing on me, which may or may not be related?

• Temenos WealthManager: performance benchmark on Exadata

  - by Javier Puerta

  Temenos WealthManager is at work in financial institutions of all sizes. No matter the size, each of Temenos’ customers has one requirement in common: a need for fast technology. This led Temenos to conduct a performance benchmark, running its WealthManager platform on Oracle Exadata Database Machine. During the study, Temenos executed high-intensity financial engines two- to three-times faster than its previous internal benchmarks and/or largest customer throughput. The company also demonstrated greater than two-times the average improvement in response times for six-times the number of users and data volumes. Further, Temenos secured a two-times gain in service-level agreements for batch and user-oriented workloads via dedicated or parallelized processing windows. Last year Temenos also communicated the availability of its T24 core banking system and how the benchmark run demonstrated the ability of Oracle’s Exadata platform to comfortably support the highest banking volumes for T24.
