  • How do I convince my boss to come here and see how "good" companies are doing?

    - by Vimvq1987
    My company is bad, I admit it. Inefficient project management, very low quality code, ... I won't get into it. It's partly based on our country's culture, but mostly because our boss is not looking at how good companies are actually going about producing good software/service. I want to bring my boss here, so he can see these things, to convince him to create a better development place for us. How can I do that? Thank you so much. Ps: If I fail to do this, you know, I'm thinking seriously of leaving

  • How to convince my boss to improve code quality?

    - by Vimvq1987
    The place I'm working for is a service provider. We have a lot of services, which are written to deal with deadline, so their code are really terrible: No coding convention, everyone codes in his own style No unit testing (which is really bad) No refactoring (which is truly worse) No automation build/deployment etc and these code are used again and again, so bad code continue to spread all over my department. I really want to set up a standard quality for our code, by requiring everyone to follow "rules": every line of code which does not follow convention will be rejected, and every function of code which does not pass unit testing will not be committed,...But I don't know how to convince my boss to allow me to do this. I'm relatively new comer, so inspiring people from my works is really hard, and I think it's easier if my boss support me to this. Thank you very much for your advices

  • Is it usual if my employer asks me to get MCP certificates for higher salary?

    - by Vimvq1987
    I just got a salary negotiation this morning (I passed three interviews last 3 weeks), and it was like a game. I was stubborn with my expectation, or that number, or I leave. OK, to be honest, it's not about money, but I, a not-very-experienced developer, want to see how much the employer pays me, and it was fun. And at last, my employer gave me this: "OK, * $, but with two conditions, first, you get your spoken skill improved (English is not my native), and second, you got MCPs before the end of the year". He asked me to get 3 MCP certificates. The company will buy any books that necessary to the exam, but I must read them at free time, take and pass the exams . If I not get them, my employer will not kick me out, but, salary discussion will be harder, for me. I accepted that offer, I thought it's good enough. But I wonder, is it usual? If you're an employer, have you ever given that offer to a candidate? If you're an employee, have you ever got, or will you accept an offer like that?

  • What is the annoying/lacking feature in C#, in your opinion?

    - by Vimvq1987
    To be honest, I'm working with C# everyday, and I can say that I love its elegant syntax. But no language is perfect, so does C#. In my opinion, these two features are missing: Full-featured enum. I was pretty happy with enum in C#, until I know about enum in Java. Of course, we can "simulate" a full-featured enum in C# by class, but it's much better if Microsoft simplify this. Immutable keyword. We are told to let a class/struct immutable whenever possible. But to do that, we have to add readonly keyword to every field, and then if we add setter by a mistake, our class will be mutable, and nobody knows. By immutable keyword, every field will be automatically readonly, and any setter will be prohibited (error when compile). It's like static keyword added to class in C# 2.0 well. what's is your annoying/lacking feature in C#?

  • Is Linux Virtual Server old, or is it standing still?

    - by Vimvq1987
    Based on this question: http://serverfault.com/questions/124905/widely-used-load-balancing-solutions, LVS may be the right solution for my problem. But when I went to its homepage http://www.linuxvirtualserver.org/, I found that LVS has been updated since Nov, 2008. The world's moving fast, and I don't know if LVS was obsolete or not. Is LVS standing still, or there're some better solutions to replace it? Thank you so much.

  • Best Linux distro for load-balancers?

    - by Vimvq1987
    I wanted to try HAProxy/Linux Virtual Server like front-end load-balancers, but as far I know, they're Linux-based software. I don't have any experiences with Linux yet. so there're quite many questions to ask: What is the best Linux distro(s) for load-balancing? I plan to use VirtualPC to run some virtual machines. How much RAM is the best for each machine run that distro? I want to simulate a load-balancer with can handle about 100 hits/second, is it possible? Thank you very much!

  • Widely-used load balancing solutions?

    - by Vimvq1987
    I asked this question http://serverfault.com/questions/124329/network-load-balancing-efficience-and-limits, and a bit disappointed that NLB was not a widely-used solution. I want to ask about widely-used solutions in the world now. Can you give me a list and a brief introduction for each? Cause of limitation of my thesis resource, I need to focus on software-only, Windows-based solution (both database level and system level are welcome). Thank you so much!

  • Network load balancing, efficience and limits?

    - by Vimvq1987
    I'm about to study about NLB on Windows Server 2003. It archives both of my interests now: scalability and high-availability. But I don't know about its power in production environment. Is NLB a efficient solution? How does it implement in real-world? Is it popular? What are its limit? Thank you so much for answering my questions. :)

  • Is Oracle Smartscan really effective?

    - by Vimvq1987
    Oracle is marketing Exadata to our company, and they're focusing on Smartscan, which is, advertised 10x more effective than traditional solution. I don't really understand (and somewhat don't really believe) this solution, because they assume that data is put on separated storage, and no indexes are used, so "1TB data was scanned and only 2MB is returned". So, I want to ask you: is Smartscan really effective. Is it true solution that greatly improves performance or just a buzzword? Thank you so much for your experience

  • Drawbacks of Windows Azure Platform?

    - by Vimvq1987
    It seems that documents available now are only whitepapers from Microsoft. So I only heard about advantages of this platform. I want to know about its drawbacks. What components/features of Windows Azure/SQL Azure/AppFabric make you uncomfortable? Which ones do you want to change/improve? Thank you so much for this.

  • Windows Azure Platform, latest version?

    - by Vimvq1987
    I searched through internet but found nothing. The whitepapers of Windows Azure Platform say something like that: In its first release, the maximum size of a single database in SQL Azure Database is 10 gigabytes A few things are omitted in the technology’s first release, however, such as the SQL Common Language Runtime (CLR) and support for spatial data. (Microsoft says that both will be available in a future version.) I want to know that Microsoft had updated Windows Azure Platform and removed these limits or not? I decided to post this question here instead of Serverfault.com because it's more relative to programming than administration. Thank you

  • Cloud computing over Client-server: differences, cons and pros ?

    - by Vimvq1987
    As far as I know, Cloud computing might be a evolution in software architect, and it will replace some current architectures, such as client-server. These two architecture seem to share similarities for me (I know very little about both), but I don't know the differences between them. What are the cons and pros of cloud computing over client-server architecture? Thank you so much.

    - by Vimvq1987
    I need to study about load-balancers, such as Network Load Balancing, Linux Virtual Server, HAProxy,...There're somethings under-the-hood I need to know: What algorithms/technologies are used in these load-balancers? Which is the most popular? most effective? I expect that these algorithms/technologies will not be too complicated. Are there some resources written about them? Thank you very much for your help.

  • Pros and cons of cloud computing?

    - by Vimvq1987
    After 3 months of research, my thesis is nearly complete. Now I'm writing the report. Interesting parts are finished, now the boring and hard-to-write parts.

So I need your helps, to list and explains all of pros and cons of cloud computing. Thank you so much for this.

  • Can someone please debug this Windows Azure Application?

    - by Vimvq1987
    Here's the myTODO project from codeplex: myTODO project I added any necessary libraries, added storage, changed obsolete types/methods, but everything went wrong when I debug it. An exception was thrown here (in TableStorage.cs): public IEnumerable<TElement> ExecuteWithRetries(RetryPolicy retry) { IEnumerable<TElement> ret = null; if (retry == null) { throw new ArgumentNullException("retry"); } retry(() => { try { ret = _query.Execute(); } catch (InvalidOperationException e) { if (TableStorageHelpers.CanBeRetried(e)) { throw new TableRetryWrapperException(e); } throw; } }); return ret; } I'm using Visual Studio 2008, SQL server 2008, Windows Azure SDK v1.1. Can anyone please debug this project for me, or suggest me someway to get it working. This request is urgent. Any helps are much appreciated. PS: If you can't download these file, please let me know, I'll upload to another hosts.

  • The future of cloud computing? [closed]

    - by Vimvq1987
    As far as I know, cloud computing is growing rapidly. Amazon EC2, Google App Engine, Microsoft Windows Azure...But I can't imagine how cloud computing will change the world. Will cloud computing will play the main role in software industry? Will our data be stored at one place and then can be accessed from any where? Shall we need powerful PCs no more because everything will be processed at "cloud"? Thank you so much

  • Better way to summarize data about stop times?

    - by Vimvq1987
    This question is close to this: http://stackoverflow.com/questions/2947963/find-the-period-of-over-speed Here's my table: Longtitude Latitude Velocity Time 102 401 40 2010-06-01 10:22:34.000 103 403 50 2010-06-01 10:40:00.000 104 405 0 2010-06-01 11:00:03.000 104 405 0 2010-06-01 11:10:05.000 105 406 35 2010-06-01 11:15:30.000 106 403 60 2010-06-01 11:20:00.000 108 404 70 2010-06-01 11:30:05.000 109 405 0 2010-06-01 11:35:00.000 109 405 0 2010-06-01 11:40:00.000 105 407 40 2010-06-01 11:50:00.000 104 406 30 2010-06-01 12:00:00.000 101 409 50 2010-06-01 12:05:30.000 104 405 0 2010-06-01 11:05:30.000 I want to summarize times when vehicle had stopped (velocity = 0), include: it had stopped since "when" to "when" in how much minutes, how many times it stopped and how much time it stopped. I wrote this query to do it: select longtitude, latitude, MIN(time), MAX(time), DATEDIFF(minute, MIN(Time), MAX(time)) as Timespan from table_1 where velocity = 0 group by longtitude,latitude select DATEDIFF(minute, MIN(Time), MAX(time)) as minute into #temp3 from table_1 where velocity = 0 group by longtitude,latitude select COUNT(*) as [number]from #temp select SUM(minute) as [totaltime] from #temp3 drop table #temp This query return: longtitude latitude (No column name) (No column name) Timespan 104 405 2010-06-01 11:00:03.000 2010-06-01 11:10:05.000 10 109 405 2010-06-01 11:35:00.000 2010-06-01 11:40:00.000 5 number 2 totaltime 15 You can see, it works fine, but I really don't like the #temp table. Is there anyway to query this without use a temp table? Thank you.
