  • How to using String.split in this case?

    - by hoang nguyen
    I want to write a fuction like that: - Input: "1" -> return : "1" - Input: "12" -> return : ["1","2"] If I use the function split(): String.valueOf("12").split("") -> ["","1","2"] But, I only want to get the result: ["1","2"]. What the best way to do this? Infact, I can do that: private List<String> decomposeQuantity(final int quantity) { LinkedList<String> list = new LinkedList<String>(); int parsedQuantity = quantity; while (parsedQuantity > 0) { list.push(String.valueOf(parsedQuantity % 10)); parsedQuantity = parsedQuantity / 10; } return list; } But, I want to use split() for having an affective code

  • The case of the mysterious MySQL caching across restarts

    - by shanusmagnus
    I found a very slow MySQL query in my web app. The weird thing is that the query is only slow the first time it's executed, despite the fact that the query_cache is set to its default (query_cache_size 0) like so: mysql> show variables like 'query%'; +------------------------------+---------+ | Variable_name | Value | +------------------------------+---------+ | query_alloc_block_size | 8192 | | query_cache_limit | 1048576 | | query_cache_min_res_unit | 4096 | | query_cache_size | 0 | | query_cache_type | ON | | query_cache_wlock_invalidate | OFF | | query_prealloc_size | 8192 | +------------------------------+---------+ The even weirder thing is that this speedup persists even after the MySQL server has been stopped and restarted (I'm using OSX, and perform this restart using the system preferences pane.) The only way I can re-create the poor performance of the initial query is by rebooting the system. So my question is: how is this happening? Obviously some sort of caching at work, but where? And how does it persist across database restarts? This query is mediated through our web app, which comes via PHP/Apache, but there are no extra bells and whistles, and the curious caching also persists across Apache restarts. Help?

  • Strangest LINQ to SQL case I have ever seen

    - by kubaw
    OK, so this is the strangest issue in .net programming I have ever seen. It seems that object fields are serialized in .net web services in order of field initialization. It all started with Flex not accepting SOAP response from .net web service. I have found out that it was due to the order of serialized fields was statisfying the order of fields in declared serializable class. It had something to do with generic lists and LINQ to SQL but I can't find out what. This one is really hard to reproduce. Example to get the idea: [Serializable] public class SomeSample { public int A; public int B; public int C; } I was querying some data tables within asmx web service using linq and returning list of SomeSample objects: var r = (from ...... select new SomeSample { A = 1, C = 3 }).ToList(); Now the list was once more iterated and B field was applied some value (ex. 2). However the returned soap envelope contained following excerpt: <A>1</A><C>3</C><B>2</B> Please notice the order of serialization. If I initially initialized all fields: var r = (from ...... select new SomeSample { A = 1, B = 2, C = 3 }).ToList(); object was serialized in correct order. I must add, that in both cases the debugger shows exactly the same content of "r" variable. Am I losing my mind or is this normal behavior? Thanks in advance.

  • CakePHP ACL use case(s)

    - by Jonathan
    I have got a simple web app in development, i want to establish a couple of user groups; Admin, Doctors & Patients. Each group would have their access restricted to particular controller actions rather than individual content. So for example, Doctors can view patient records (index & view actions), but cannot delete them. Usually i would create a groups model, and assign the various users to a group. And filter in the beforeFilter() method to determine if the user has access. But if ACL can do the job, why right the code, right? Thanks

  • Is it a good idea to define a variable in a local block for a case of a switch statement?

    - by Paperflyer
    I have a rather long switch-case statement. Some of the cases are really short and trivial. A few are longer and need some variables that are never used anywhere else, like this: switch (action) { case kSimpleAction: // Do something simple break; case kComplexAction: { int specialVariable = 5; // Do something complex with specialVariable } break; } The alternative would be to declare that variable before going into the switch like this: int specialVariable = 5; switch (action) { case kSimpleAction: // Do something simple break; case kComplexAction: // Do something complex with specialVariable break; } This can get rather confusing since it is not clear to which case the variable belongs and it uses some unnecessary memory. However, I have never seen this usage anywhere else. Do you think it is a good idea to declare variables locally in a block for a single case?

  • Specification: Use cases for CRUD

    - by Mario Ortegón
    I am writing a Product requirements specification. In this document I must describe the ways that the user can interact with the system in a very high level. Several of these operations are "Create-Read-Update-Delete" on some objects. The question is, when writing use cases for these operations, what is the right way to do so? Can I write only one Use Case called "Manage Object x" and then have these operations as included Use Cases? Or do I have to create one use case per operation, per object? The problem I see with the last approach is that I would be writing quite a few pages that I feel do not really contribute to the understanding of the problem. What is the best practice?

  • Is there a way to refactor this javascript/jquery?

    switch (options.effect) { case 'h-blinds-fadein': $('.child').each(function (i) { $(this).stop().css({opacity:0}).delay(100 * i).animate({ 'opacity': 1 }, { duration: options.speed, complete: (i !== r * c - 1) || function () { $(this).parent().replaceWith(prev); options.cp.bind('click',{effect: options.effect},options.ch); } }); }); break; case 'h-blinds-fadein-reverse': $('.child').each(function (i) { $(this).stop().css({opacity:0}).delay(100 * (r * c - i)).animate({ 'opacity': 1 }, { duration: options.speed, complete: (i !== 0) || function () { $(this).parent().replaceWith(prev); options.cp.bind('click',{effect: options.effect},options.ch); } }); }); break; ....more cases } I have alot of similiar other cases. One way i could think of is to write functions ? i'm not sure i'm still fairly new to the language

  • sql query where parameters null not null

    - by Laziale
    I am trying to do a sql query and to build the where condition dynamically depending if the parameters are null or no. I have something like this: SELECT tblOrder.ProdOrder, tblOrder.Customer FROM tblOrder CASE WHEN @OrderId IS NOT NULL THEN WHERE tblOrder.OrderId = @OrderId ELSE END CASE WHEN @OrderCustomer IS NOT NULL THEN AND tblOrder.OrderCustomer = @OrderCustomer ELSE END END This doesn't work, but this is just a small prototype how to assemble the query, so if the orderid is not null include in the where clause, or if the ordercustomer is not null include in the where clause. But I see problem here, for example if the ordercustomer is not null but the orderid is null, there will be error because the where keyword is not included. Any advice how I can tackle this problem. Thanks in advance, Laziale

  • How can you control the speed of fan that comes with the Antec Sonata III case from the outside?

    - by Emil Lerch
    The Antec Sonata III case comes with a nice 120mm fan that has a 3 speed switch. Most of the time the fan is fine on low, but for games or other taxing workloads I need to switch it to medium or high. Opening the case every time I want to change the setting is kind of a pain. Has anyone figured out a way to control the speed from the outside of the case without going nuclear (e.g. cutting holes in the case)? Other than this annoyance I like the case and the fan that comes with it.

  • Are there any actual case studies on rewrites of software success/failure rates?

    - by James Drinkard
    I've seen multiple posts about rewrites of applications being bad, peoples experiences about it here on Programmers, and an article I've ready by Joel Splosky on the subject, but no hard evidence of case studies. Other than the two examples Joel gave and some other posts here, what do you do with a bad codebase and how do you decide what to do with it based on real studies? For the case in point, there are two clients I know of that both have old legacy code. They keep limping along with it because as one of them found out, a rewrite was a disaster, it was expensive and didn't really work to improve the code much. That customer has some very complicated business logic as the rewriters quickly found out. In both cases, these are mission critical applications that brings in a lot of revenue for the company. The one that attempted the rewrite felt that they would hit a brick wall at some point if the legacy software didn't get upgraded at some point in the future. To me, that kind of risk warrants research and analysis to ensure a successful path. My question is have there been actual case studies that have investigated this? I wouldn't want to attempt a major rewrite without knowing some best practices, pitfalls, and successes based on actual studies. Aftermath: okay, I was wrong, I did find one article: Rewrite or Reuse. They did a study on a Cobol app that was converted to Java.

  • Cheap desktop computer in 19" rack-mountable form-factor?

    - by Alex Basson
    I'm a high school teacher at a small private school. As of this year, we have SMARTBoards in every classroom (though I've had one in the class I share for two years now). The classrooms themselves don't have computers in them, so we teachers bring our laptops to class and connect them to the boards. This has several disadvantages: This takes a few minutes while we wait for the board to boot up and then orient the board to our individual laptop -- we have to do this every time b/c different teachers have different laptops requiring different orientations. This isn't ideal because when you only have 43 minutes per class period, waiting five minutes just to get started is a real waste. Carrying your laptop to class doesn't sound so bad until you consider that we're also carrying textbooks and piles of student papers, and we're carrying it all through crowded high school hallways. More than one laptop has fallen THUNK to the floor, with dire consequences. We feel we could eliminate the need to use our laptops with the SMARTBoards if we had a dedicated computer in each classroom hooked up to the board at all times. Each board set-up is connected to a podium with a standard 19" rack in it, currently housing a power supply and DVD player. There're plenty of rack spaces available. So I'm thinking: maybe we could get some inexpensive computers in a 19" rack-mountable form factor, install them in the podiums, and connect them to the boards on a permanent basis. Any suggestions?

  • How do I clean dust from a computer?

    - by Jonas
    As computers become faster and generate more heat it gets more important to have good ventilation, but that also increases the amount of dust sticking to the components of the computer. It's of course better to make sure the computer never gets dusty by vacuum cleaning around it (not in it) frequently. But what to do if it's already to late? I've heard that vacuum cleaning the computer itself is very bad, since it can cause static electricity that hurts the computer. So, Does anyone have any tips for how to remove dust from your computer?

  • How to remove the smell of cigarette from the computer?

    - by Tio
    So I'm a smoker, and of course I smoke in front of the computer when I'm at home. On last Friday I moved out from my mothers house to my own, and since the computers were always turned on and the room was a room that everybody could smoke, the smell didn't bother me. At my new home, I turned them on, about 15 minutes ago, and I'm dying because of the smell of cigarette ( this may be kind of stupid from a smoker, but I hope some of you understand ). This solution has to be relatively quick, because I can't stay without the desktop and the server for one week, for example. Tomorrow, I'm going to open them both, and remove all dust there is inside, this should clear some of the smell, but probably won't remove it completely. Does anyone know a technique to get rid of the smell?

  • 2.5" SSD in a 3.5" desktop drive bay normal?

    - by Cory Petosky
    I'm a little out of touch with modern desktop builds, but I recently built a new machine anyway. I want to pick up a SSD for my I/O intensive apps (EverQuest 2 and Flash CS4 mostly), but I'm having trouble finding any in the 3.5" form factor. Is this expected, or do I fail at product search? And, if it is expected, do 2.5" SSDs come with an adapter to fit them in my desktop machine, or will I need to purchase one separately? And, finally, if I do need to purchase an adapter, are they pretty standard or are some better than others. General advice is most welcomed, though specific product recommendations in addition would be helpful!

  • USB port causing device problems after new motherboard upgrade

    - by enbuyukfener
    I'm looking into a PC with an issue with one of the front USB ports (perhaps both). It was working before a motherboard upgrade but since then, a USB drive was inserted, overheated and does not appear to be working. Then a phone (with USB charging) was plugged in, and the phone OS suspended. Removing and re-inserting the battery led to the phone (and hence battery) working, however the battery no longer charges (including with a wall charger). It seems too much to be a coincidence and am wondering what the issue may be? Ideas so far are short circuiting, or over-current to the USB ports. Note: Did not occur to me, so details are not 100% accurate or complete. Feel free to ask for missing info that I may have forgotten though.
