  • Is there a Windows 7 add-on that will put the PID in the title bar of a window?

    - by Chris
    Occasionally I run many instances of something, like Chrome or Visual Studio. Rarely, but often enough to bug me, one of them gets hosed and starts to consume 100% CPU. I can fire up the task manager to see which process is using 100%, but if it just says chrome.exe or devenv.exe, I don't know which window is the culprit. I'd like to know before terminating the process, so I can activate the app and shut it down cleanly. The best I've found so far is to use Process Explorer's feature where I can right click a process and say "bring to front". But I am curious as to whether there is an app that will put the PID(s) right in the title bar of the window so I can tell which window matches the process. I am using Windows 7 64-bit.

  • How should data be passed between client-side Javascript and C# code behind an ASP.NET app?

    - by ctck
    I'm looking for the most efficient / standard way of passing data between client-side Javascript code and C# code behind an ASP.NET application. I've been using the following methods to achieve this but they all feel a bit of a fudge. To pass data from Javascript to the C# code is by setting hidden ASP variables and triggering a postback: <asp:HiddenField ID="RandomList" runat="server" /> function SetDataField(data) { document.getElementById('<%=RandomList.ClientID%>').value = data; } Then in the C# code I collect the list: protected void GetData(object sender, EventArgs e) { var _list = RandomList.value; } Going back the other way I often use either ScriptManager to register a function and pass it data during Page_Load: ScriptManager.RegisterStartupScript(this.GetType(), "Set","get("Test();",true); or I add attributes to controls before a post back or during the initialization or pre-rendering stages: Btn.Attributes.Add("onclick", "DisplayMessage("Hello");"); These methods have served me well and do the job, but they just dont feel complete. Is there a more standard way of passing data between client side Javascript and C# backend code? Ive seen some posts like this one that describe HtmlElement class; is this something I should look into?

  • GIMP Slow Startup

    - by muntoo
    Is there any way to speed up GIMP's startup time on Windows Vista Home Premium 32-Bit 1.6 [Dual] Intel Processors? On XP [different computer], it loads in less than 3 seconds. On Vista, it takes 20 seconds: 2 Seconds (other - fonts, brushes, etc) 18 Seconds (extension-script-fu) It just freezes at extension-script-fu. Looking at ProcessExplorer (or Task Manager, whatever), I see that it's not taking any CPU. EDIT: it does seem to be taking 50% of the CPU. It gets stuck for about 18 seconds, then starts working again, and the actual GIMP program pops up [...finally]. I have the latest stable version running (I think). I tried it with XP SP2 Compatibiliy mode and/or Run As Administrator, but that didn't help. EDIT: One way would be to disable script-fu. Does anyone know how to disable it at startup? (NOTE: Just wanted to point out that the title and the tags are the same. :D )

  • Windows 7 PC crashes after being locked a few minutes

    - by White Island
    I have a problem with an Optiplex 755 PC running (32-bit) Windows 7 Professional. I just installed the operating system last week, and ever since, it seems to crash when I lock the screen. It doesn't happen immediately; it's usually after I walk away, so a few minutes (but I'm not sure exactly how many). I have this non-specific error in the Event log. I've run a chkdsk, thinking it might be hard drive-related, but that didn't help. Any ideas on what to check and how are appreciated. :) Log Name: System Source: Microsoft-Windows-Kernel-Power Date: 11/17/2010 3:09:28 PM Event ID: 41 Task Category: (63) Level: Critical Keywords: (2) User: SYSTEM Computer: WORKSTATION.domain.local Description: The system has rebooted without cleanly shutting down first.

  • How do I make complex SQL queries easier to write?

    - by DragonLord
    I'm finding it very difficult to write complex SQL queries involving joins across many (at least 3-4) tables and involving several nested conditions. The queries I'm being asked to write are easily described by a few sentences, but can require a deceptive amount of code to complete. I'm finding myself often using temporary views to write these queries, which seem like a bit of a crutch. What tips can you provide that I can use to make these complex queries easier? More specifically, how do I break these queries down into the steps I need to use to actually write the SQL code? Note that I'm the SQL I'm being asked to write is part of homework assignments for a database course, so I don't want software that will do the work for me. I want to actually understand the code I'm writing. More technical details: The database is hosted on a PostgreSQL server running on the local machine. The database is very small: there are no more than seven tables and the largest table has less than about 50 rows. The SQL queries are being passed unchanged to the server, via LibreOffice Base.

  • How to "FTP jail" with Pure-FTPD?

    - by Nate
    I asked this a little bit ago, but instead of specifying Pure-FTPD I just said Apache. Per the answer to that question, I'm asking again with "Pure-FTPD" in the title this time. I need to allow someone access to my VPS via FTP, but there are a number of directories that the person must not be allowed to view or modify. For example, something like this: private_info_1 public_info_1 private_info_2 public_info_2 In this example, the FTP user would need to be allowed to do stuff in the public directories, but not the private ones. How do I go about doing this with Pure-FTPD? I have cPanel and SSH access.

  • JavaScript objects and Crockford's The Good Parts

    - by Jonathan
    I've been thinking quite a bit about how to do OOP in JS, especially when it comes to encapsulation and inheritance, recently. According to Crockford, classical is harmful because of new(), and both prototypal and classical are limited because their use of constructor.prototype means you can't use closures for encapsulation. Recently, I've considered the following couple of points about encapsulation: Encapsulation kills performance. It makes you add functions to EACH member object rather than to the prototype, because each object's methods have different closures (each object has different private members). Encapsulation forces the ugly "var that = this" workaround, to get private helper functions to have access to the instance they're attached to. Either that or make sure you call them with privateFunction.apply(this) everytime. Are there workarounds for either of two issues I mentioned? if not, do you still consider encapsulation to be worth it? Sidenote: The functional pattern Crockford describes doesn't even let you add public methods that only touch public members, since it completely forgoes the use of new() and constructor.prototype. Wouldn't a hybrid approach where you use classical inheritance and new(), but also call Super.apply(this, arguments) to initialize private members and privileged methods, be superior?

  • Upgrading Ubuntu hardy to Ruby 1.8.7

    - by Simone Carletti
    My server is running Ubuntu Hardy and Ruby 1.8.6 installed using aptitude. I'd like to upgrade to Ruby 1.8.7 but, unfortunately, the Ruby package includes Ruby 1.8.7 starting from Ubuntu Intrepid. I read a couple of tutorials about how to upgrade to Ruby 1.8.7 and I found at least 3 different way to accomplish this task: backports installation from source installation from source and multiple versions I'm a bit confused. How do you recommend to upgrade to Ruby 1.8.7 taking into consideration I don't need multiple Ruby versions on the same server? I'd like to cleanly replace the existing Ruby 1.8.6 with Ruby 1.8.7.

  • Converting a JD Edwards Date to a System.DateTime

    - by Christopher House
    I'm working on moving some data from JD Edwards to a SQL Server database using SSIS and needed to deal with the way in which JDE stores dates.  The format is CYYDDD, where: C = century, 1 for >= 2000 and 0 for < 2000 YY = the last two digits of the year DDD = the number of the day.  Jan 1 = 1, Dec. 31 = 365 (or 366 in a leap year) The .Net base class library has lots of good support for handling dates, but nothing as specific as the JD Edwards format, so I needed to write a bit of code to translate the JDE format to System.DateTime.  The function is below: public static DateTime FromJdeDate(double jdeDate) {   DateTime convertedDate = DateTime.MinValue;   if (jdeDate >= 30001 && jdeDate <= 200000)   {     short yearValue = (short)(jdeDate / 1000d + 1900d);     short dayValue = (short)((jdeDate % 1000) - 1);     convertedDate = DateTime.Parse("01/01/" + yearValue.ToString()).AddDays(dayValue);   }   else   {     throw new ArgumentException("The value provided does not represent a valid JDE date", "jdeDate");   }   return convertedDate; }  I'd love to take credit for this myself, but this is an adaptation of a TSQL UDF that I got from another consultant at the client site.

  • Is it reasonable to expect knowing the whole stack bottom up?

    - by Vaibhav Garg
    I am an Sr. developer/architect/Product Manager for embedded systems. The systems that I have had experience with have typically been small to medium size codebases - typically close to 25-30K LOC in C, using 8-16 and 32 bit low end microcontrollers. The systems have been entirely bootstrapped by our team - meaning right from the start-up code to the end application code has either been written by the team, or at the very least, is thoroughly understood and maintained by us. Now, if we were to start developing more complex systems with complex peripherals, such as USB OTG et al. (think, low end cell phones), there are libraries and stacks available commercially and from chip vendors that reduce the task to just calling the right APIs and being able to use those peripherals. Now, from a habit point of view, this does not give me and the team a comfortable feeling, not being able to comprehend the entire code tree, with virtual black boxes at the lower layers. Is it reasonable to devote, and reserve, time getting into the details of how the APIs are implemented, assuming that the same would also entail getting into details of relevant standards (again, for USB as an example)? Or, alternatively, should a thorough understanding of the top level usage of the APIs be sufficient? This of course assumes that the source codes to all libraries are available, which they are, in almost all cases. Edit: In partial response to @Abhi Beckert, the documentation is refreshingly very comprehensive and meticulously maintained, AFAIK and been able to judge. I have not had a long experience with the same.

  • How would you shorten 5,000+ URLs? [closed]

    - by Tyler J Fisher
    How would you go about shortening approximately 5,000 permalinks? The links point to a remote media archiving server, and are unlikely to change. Example URLs: rtsp://foo-1.bar.com/xx/xx/xx/xx.rm http://media.foo.org/xx/xx/xx.mp4 The URLs are going to be stored in a local MySQL database, as such it's crucial that the URLs are in a manageable form (i.e bit.ly or ow.ly). There are bulk URL shortening services, but those only allow shortening of 100 links/day, which isn't technically feasible so I need to think of something else.

  • Are there any FIPS-140-2 certified solutions for Linux?

    - by Mark Renouf
    I'm not even 100% certain what this involves, but my current understanding is this: use of only approved cryptographic algorithms for network traffic (easy, we use SSL and lock down the algorithms to only the really strong ones). Some form of physical data protection, involving disk encryption and physical tamper evident packaging. Obviously we're on our own if we need a tamper-proof product. But what about software for encrpytion. My guess is just using LUKS (although secure) will not be certified because it's open source (gov't seems a bit biased towards proprietary solutions here). Guardian Edge was mentioned by someone, but that appears to be complete Windows-based. So we need something like it, certified FIPS-140 compliant we can use on Linux.

  • Setting properties in chef-client.rb

    - by Stephen C
    I have a use-case where a chef recipe needs to use 'remote_file' to fetch a file on a virtual, and the fetch needs to be do through an HTTP proxy. This is not working because chef-client doesn't use the system proxy settings ... it gets its proxy settings from the /etc/chef/chef-client.rb So how do I get proxy settings (or settings in general) into the chef-client.rb file on a client? Ideally, I'd like it to happen at client bootstrap time, but I can't see how to do that short of hacking the code. The other possibility is that I could create a recipe that updates the chef-client.rb file. But that strikes me as a bit dangerous. And it means that you need to run chef-client twice before it works, assuming that the missing proxy setting in the first run causes the run to ultimately fail. Any ideas on how to fix this?

  • Getting SQL table row counts via sysindexes vs. sys.indexes

    - by Bill Osuch
    Among the many useful SQL snippets I regularly use is this little bit that will return row counts in a table: SELECT so.name as TableName, MAX(si.rows) as [RowCount] FROM sysobjects so JOIN sysindexes si ON si.id = OBJECT_ID(so.name) WHERE so.xtype = 'U' GROUP BY so.name ORDER BY [RowCount] DESC This is handy to find tables that have grown wildly, zero-row tables that could (possibly) be dropped, or other clues into the data. Right off the bat you may spot some "non-ideal" code - I'm using sysobjects rather than sys.objects. What's the difference? In SQL Server 2005 and later, sysobjects is no longer a table, but a "compatibility view", meant for backward compatibility only. SELECT * from each and you'll see the different data that each returns. Microsoft advises that sysindexes could be removed in a future version of SQL Server, but this has never really been an issue for me since my company is still using SQL 2000. However, there are murmurs that we may actually migrate to 2008 some year, so I might as well go ahead and start using an updated version of this snippet on the servers that can handle it: SELECT so.name as TableName, ddps.row_count as [RowCount] FROM sys.objects so JOIN sys.indexes si ON si.OBJECT_ID = so.OBJECT_ID JOIN sys.dm_db_partition_stats AS ddps ON si.OBJECT_ID = ddps.OBJECT_ID  AND si.index_id = ddps.index_id WHERE si.index_id < 2  AND so.is_ms_shipped = 0 ORDER BY ddps.row_count DESC

  • The Cloud is STILL too slow!

    - by harry.foxwell(at)oracle.com
    If you've been in the computing industry sufficiently long enough to remember dialup modems and other "ancient" technologies, you might be tempted to marvel at today's wonderfully powerful multicore PCs, ginormous disks, and blazingly fast networks.  Wow, you're in Internet Nirvana, right!  Well, no, not by a long shot.Considering the exponentially growing expectations of what the Web, that is, "the Cloud", is supposed to provide, today's Web/Cloud services are still way too slow.Already we are seeing cloud-enabled consumer devices that are stressing even the most advanced public network services.  Like the iPad and its competitors, ever more powerful smart-phones, and an imminent hoard of special purpose gadgets such as the proposed "cloud camera" (see http://gdgt.com/discuss/it-time-cloud-camera-found-out-cnr/ ).And at the same time that the number and type of cloud services are growing, user tolerance for even the slightest of download delays is rapidly decreasing.  Ten years ago Web developers followed the "8-Second Rule", (average time a typical Web user would tolerate for a page to download and render).  Not anymore; now it's less than 3 seconds, and only a bit longer for mobile devices (see http://www.technologyreview.com/files/54902/GoogleSpeed_charts.pdf).  How spoiled we've become!Google, among others, recognizes this problem and is working to encourage the development of a faster Web (see http://www.technologyreview.com/web/32338/). They, along with their competitors and ISPs, will have to encourage and support significantly better Web performance in order to provide the types of services envisioned for the Cloud.  How will they do this? Through the development of faster components, better use of caching technologies, and the really tough one - exploiting parallelism. Not that parallel technologies like multicore processors are hard to build...we already have them.  It's just that we're not that good yet at using them effectively.  And if we don't get better, users will abandon cloud-based services...in less than 3 seconds.

  • Samsung 830 very slow benchmark numbers

    - by alekop
    I just bought a new SSD, and installed a fresh copy of Windows on it. I didn't see any noticeable difference in boot times, app start-up times, so I decided to benchmark it. Asus P7P55D-E Intel i5-760 Samsung 830 256GB SATA III Windows 7 Ultimate 64-bit The Windows experience index gave the drive a 7.3 rating, but real-world performance is not particularly impressive. Any ideas why the numbers are so low? UPDATE: It turns out that SATA III support is turned off by default on the P7P55D motherboard. After enabling it in BIOS (Tools - Level Up), the scores went up: Read Write Seq 325 183 4K 16 49 IOPS 32K 28K It's an improvement, but still far below what they should be for this drive.

  • uWSGI and Nginx python file handling

    - by user133507
    I've been trying to figure out how to propertly utilize uWSGI with Nginx and have hit a bit of a design roadblock. I'm trying to figure out how my python files should be accessed via uWSGI. I've been able to find 3 different ways to do so: Create a uWSGI process for each python file and then create locations in nginx that pass to each uWSGI process. Create one instance of uWSGI and create a master python file that handles all the different requests. Create one instance of uWSGI and setup dynamic applications I'm coming from LightTPD where I simply setup rewrites to point at the different python files. I feel like 3 is the closest to that but uWSGI says that it is not the recommended way of going about it.

  • C#/.NET Little Wonders: Tuples and Tuple Factory Methods

    - by James Michael Hare
    Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can really help improve your code by making it easier to write and maintain.  This week, we look at the System.Tuple class and the handy factory methods for creating a Tuple by inferring the types. What is a Tuple? The System.Tuple is a class that tends to inspire a reaction in one of two ways: love or hate.  Simply put, a Tuple is a data structure that holds a specific number of items of a specific type in a specific order.  That is, a Tuple<int, string, int> is a tuple that contains exactly three items: an int, followed by a string, followed by an int.  The sequence is important not only to distinguish between two members of the tuple with the same type, but also for comparisons between tuples.  Some people tend to love tuples because they give you a quick way to combine multiple values into one result.  This can be handy for returning more than one value from a method (without using out or ref parameters), or for creating a compound key to a Dictionary, or any other purpose you can think of.  They can be especially handy when passing a series of items into a call that only takes one object parameter, such as passing an argument to a thread's startup routine.  In these cases, you do not need to define a class, simply create a tuple containing the types you wish to return, and you are ready to go? On the other hand, there are some people who see tuples as a crutch in object-oriented design.  They may view the tuple as a very watered down class with very little inherent semantic meaning.  As an example, what if you saw this in a piece of code: 1: var x = new Tuple<int, int>(2, 5); What are the contents of this tuple?  If the tuple isn't named appropriately, and if the contents of each member are not self evident from the type this can be a confusing question.  The people who tend to be against tuples would rather you explicitly code a class to contain the values, such as: 1: public sealed class RetrySettings 2: { 3: public int TimeoutSeconds { get; set; } 4: public int MaxRetries { get; set; } 5: } Here, the meaning of each int in the class is much more clear, but it's a bit more work to create the class and can clutter a solution with extra classes. So, what's the correct way to go?  That's a tough call.  You will have people who will argue quite well for one or the other.  For me, I consider the Tuple to be a tool to make it easy to collect values together easily.  There are times when I just need to combine items for a key or a result, in which case the tuple is short lived and so the meaning isn't easily lost and I feel this is a good compromise.  If the scope of the collection of items, though, is more application-wide I tend to favor creating a full class. Finally, it should be noted that tuples are immutable.  That means they are assigned a value at construction, and that value cannot be changed.  Now, of course if the tuple contains an item of a reference type, this means that the reference is immutable and not the item referred to. Tuples from 1 to N Tuples come in all sizes, you can have as few as one element in your tuple, or as many as you like.  However, since C# generics can't have an infinite generic type parameter list, any items after 7 have to be collapsed into another tuple, as we'll show shortly. So when you declare your tuple from sizes 1 (a 1-tuple or singleton) to 7 (a 7-tuple or septuple), simply include the appropriate number of type arguments: 1: // a singleton tuple of integer 2: Tuple<int> x; 3:  4: // or more 5: Tuple<int, double> y; 6:  7: // up to seven 8: Tuple<int, double, char, double, int, string, uint> z; Anything eight and above, and we have to nest tuples inside of tuples.  The last element of the 8-tuple is the generic type parameter Rest, this is special in that the Tuple checks to make sure at runtime that the type is a Tuple.  This means that a simple 8-tuple must nest a singleton tuple (one of the good uses for a singleton tuple, by the way) for the Rest property. 1: // an 8-tuple 2: Tuple<int, int, int, int, int, double, char, Tuple<string>> t8; 3:  4: // an 9-tuple 5: Tuple<int, int, int, int, double, int, char, Tuple<string, DateTime>> t9; 6:  7: // a 16-tuple 8: Tuple<int, int, int, int, int, int, int, Tuple<int, int, int, int, int, int, int, Tuple<int,int>>> t14; Notice that on the 14-tuple we had to have a nested tuple in the nested tuple.  Since the tuple can only support up to seven items, and then a rest element, that means that if the nested tuple needs more than seven items you must nest in it as well.  Constructing tuples Constructing tuples is just as straightforward as declaring them.  That said, you have two distinct ways to do it.  The first is to construct the tuple explicitly yourself: 1: var t3 = new Tuple<int, string, double>(1, "Hello", 3.1415927); This creates a triple that has an int, string, and double and assigns the values 1, "Hello", and 3.1415927 respectively.  Make sure the order of the arguments supplied matches the order of the types!  Also notice that we can't half-assign a tuple or create a default tuple.  Tuples are immutable (you can't change the values once constructed), so thus you must provide all values at construction time. Another way to easily create tuples is to do it implicitly using the System.Tuple static class's Create() factory methods.  These methods (much like C++'s std::make_pair method) will infer the types from the method call so you don't have to type them in.  This can dramatically reduce the amount of typing required especially for complex tuples! 1: // this 4-tuple is typed Tuple<int, double, string, char> 2: var t4 = Tuple.Create(42, 3.1415927, "Love", 'X'); Notice how much easier it is to use the factory methods and infer the types?  This can cut down on typing quite a bit when constructing tuples.  The Create() factory method can construct from a 1-tuple (singleton) to an 8-tuple (octuple), which of course will be a octuple where the last item is a singleton as we described before in nested tuples. Accessing tuple members Accessing a tuple's members is simplicity itself… mostly.  The properties for accessing up to the first seven items are Item1, Item2, …, Item7.  If you have an octuple or beyond, the final property is Rest which will give you the nested tuple which you can then access in a similar matter.  Once again, keep in mind that these are read-only properties and cannot be changed. 1: // for septuples and below, use the Item properties 2: var t1 = Tuple.Create(42, 3.14); 3:  4: Console.WriteLine("First item is {0} and second is {1}", 5: t1.Item1, t1.Item2); 6:  7: // for octuples and above, use Rest to retrieve nested tuple 8: var t9 = new Tuple<int, int, int, int, int, int, int, 9: Tuple<int, int>>(1,2,3,4,5,6,7,Tuple.Create(8,9)); 10:  11: Console.WriteLine("The 8th item is {0}", t9.Rest.Item1); Tuples are IStructuralComparable and IStructuralEquatable Most of you know about IComparable and IEquatable, what you may not know is that there are two sister interfaces to these that were added in .NET 4.0 to help support tuples.  These IStructuralComparable and IStructuralEquatable make it easy to compare two tuples for equality and ordering.  This is invaluable for sorting, and makes it easy to use tuples as a compound-key to a dictionary (one of my favorite uses)! Why is this so important?  Remember when we said that some folks think tuples are too generic and you should define a custom class?  This is all well and good, but if you want to design a custom class that can automatically order itself based on its members and build a hash code for itself based on its members, it is no longer a trivial task!  Thankfully the tuple does this all for you through the explicit implementations of these interfaces. For equality, two tuples are equal if all elements are equal between the two tuples, that is if t1.Item1 == t2.Item1 and t1.Item2 == t2.Item2, and so on.  For ordering, it's a little more complex in that it compares the two tuples one at a time starting at Item1, and sees which one has a smaller Item1.  If one has a smaller Item1, it is the smaller tuple.  However if both Item1 are the same, it compares Item2 and so on. For example: 1: var t1 = Tuple.Create(1, 3.14, "Hi"); 2: var t2 = Tuple.Create(1, 3.14, "Hi"); 3: var t3 = Tuple.Create(2, 2.72, "Bye"); 4:  5: // true, t1 == t2 because all items are == 6: Console.WriteLine("t1 == t2 : " + t1.Equals(t2)); 7:  8: // false, t1 != t2 because at least one item different 9: Console.WriteLine("t2 == t2 : " + t2.Equals(t3)); The actual implementation of IComparable, IEquatable, IStructuralComparable, and IStructuralEquatable is explicit, so if you want to invoke the methods defined there you'll have to manually cast to the appropriate interface: 1: // true because t1.Item1 < t3.Item1, if had been same would check Item2 and so on 2: Console.WriteLine("t1 < t3 : " + (((IComparable)t1).CompareTo(t3) < 0)); So, as I mentioned, the fact that tuples are automatically equatable and comparable (provided the types you use define equality and comparability as needed) means that we can use tuples for compound keys in hashing and ordering containers like Dictionary and SortedList: 1: var tupleDict = new Dictionary<Tuple<int, double, string>, string>(); 2:  3: tupleDict.Add(t1, "First tuple"); 4: tupleDict.Add(t2, "Second tuple"); 5: tupleDict.Add(t3, "Third tuple"); Because IEquatable defines GetHashCode(), and Tuple's IStructuralEquatable implementation creates this hash code by combining the hash codes of the members, this makes using the tuple as a complex key quite easy!  For example, let's say you are creating account charts for a financial application, and you want to cache those charts in a Dictionary based on the account number and the number of days of chart data (for example, a 1 day chart, 1 week chart, etc): 1: // the account number (string) and number of days (int) are key to get cached chart 2: var chartCache = new Dictionary<Tuple<string, int>, IChart>(); Summary The System.Tuple, like any tool, is best used where it will achieve a greater benefit.  I wouldn't advise overusing them, on objects with a large scope or it can become difficult to maintain.  However, when used properly in a well defined scope they can make your code cleaner and easier to maintain by removing the need for extraneous POCOs and custom property hashing and ordering. They are especially useful in defining compound keys to IDictionary implementations and for returning multiple values from methods, or passing multiple values to a single object parameter.

  • Shell Script Launching Child Processes

    - by Matt James
    Disclaimer: I'm totally new to shell scripting, but have quite a bit of experience in other languages like PHP and Obj-C. I'm writing my first daemon script. Here are the goals: I want it to run in the background I want it to be triggered by an init.d script that includes start/stop/restart commands I want each process in a loop to trigger its own subprocess. When the parent process kicked off by the init.d script is killed, I want the subprocesses to die as well. Essentially, I'm looking for the same kind of behavior that appears to be very common among software like apache, spamd, dovecot, etc. But, based on my research, I haven't found a single, simple answer as to how this kind of thing is achieved. Any help is greatly appreciated.

  • Default Window Size

    - by muntoo
    I'm running Vista Home Premium 32-Bit, though I doubt that matters, in this case. So, how do you set the default windows size? Is there a registry tweak for this? Going to Tools->Folder Options...->View Apply to Folders or Reset Folders doesn't work. So, whenever I open a new window to a random new folder I haven't opened before, I don't want it to take 75% of the screen. Is there any way I could make it open smaller?

  • Running IE on OSX with WineBottler: Can't find wine?

    - by AP257
    So I want to run IE7 on OSX 10.6 with WineBottler. I saw it was possible to run IE on Mac with WineBottler, following these instructions. I installed WineBottler and IE7. All was looking good. However, when I tried to open IE7 from the Applications menu, I got an error message: "Can't find Wine. Wine is required to run this program." I then installed wine-devel from macports (which was a bit fiddly as I hit this problem and had to update a lot of dependencies, but it did eventually build). However, even after doing that, I'm still seeing the 'Can't find wine' error message whenever I try to open IE7 or WineBottler. Could anyone advise? Do I need to start wine running somehow?

  • List SQL Server Instances using the Registry

    - by BuckWoody
    I read this interesting article on using PowerShell and the registry, and thought I would modify his information a bit to list the SQL Server Instances on a box. The interesting thing about listing instances this was is that you can touch remote machines, find the instances when they are off and so on. Anyway, here’s the scriptlet I used to find the Instances on my system: $MachineName = '.' $reg = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $MachineName) $regKey= $reg.OpenSubKey("SOFTWARE\\Microsoft\\Microsoft SQL Server\\Instance Names\\SQL" ) $regkey.GetValueNames() You can read more of his article to find out the reason for the remote registry call and so forth – there are also security implications here for being able to read the registry. Script Disclaimer, for people who need to be told this sort of thing: Never trust any script, including those that you find here, until you understand exactly what it does and how it will act on your systems.

  • How do I stop XNA/Visual Studio from rebuilding my content project every time I build?

    - by Phil Quinn
    My group and I are working on a game in XNA 4.0 with Visual Studio 2010/2012. The main solution has 6 projects: 2 XNA game projects (1 executable/ 1 class library), 1 WPF executable for the level editor, 2 standard class libraries, and a content project. Originally, the editor and engine XNA game projects had a content reference to separate content projects. Recently, I consolidated the content projects into one to simplify asset additions. Since pushing these changes to our git repo, certain members of my group have been experiencing weird build issues. Every time they run the project, they have to re-build all of the assets. This happens regardless of whether any changes were made, even if they just run the project directly after building. I've taken a few steps to figure out why this is happening. Below is the MSBuild output set on Normal verbosity. The seemingly important part is at 4, with the line 4> Rebuilding all content because build settings have changed 1>------ Build started: Project: Engine.Core, Configuration: Debug x86 ------ 1>Build

Like I said, this only happens for half our group. One member is on a 32-bit Windows 7 Prof bootcamp partition on a Mac. Everyone else, including those who don't have the issue, are running straight 64-bit Windows 7 Prof. Both have tried using VS 2010 and VS 2012. Any insight would be greatly appreciated. Also, I can post more details upon request if this isn't thorough enough.
