• regex numeric data processing: match a series of numbers greater than X

  - by Mu Mind

  Say I have some data like this: number_stream = [0,0,0,7,8,0,0,2,5,6,10,11,10,13,5,0,1,0,...] I want to process it looking for "bumps" that meet a certain pattern. Imagine I have my own customized regex language for working on numbers, where [[ =5 ]] represents any number = 5. I want to capture this case: ([[ >=5 ]]{3,})[[ <3 ]]{2,} In other words, I want to begin capturing any time I look ahead and see 3 or more values = 5 in a row, and stop capturing any time I look ahead and see 2+ values < 3. So my output should be: >>> stream_processor.process(number_stream) [[5,6,10,11,10,13,5],...] Note that the first 7,8,... is ignored because it's not long enough, and that the capture ends before the 0,1,0.... I'd also like a stream_processor object I can incrementally pass more data into in subsequent process calls, and return captured chunks as they're completed. I've written some code to do it, but it was hideous and state-machiney, and I can't help feeling like I'm missing something obvious. Any ideas to do this cleanly?

• Implementing search functionality with multiple optional parameters against database table.

  - by quarkX

  Hello, I would like to check if there is a preferred design pattern for implementing search functionality with multiple optional parameters against database table where the access to the database should be only via stored procedures. The targeted platform is .Net with SQL 2005, 2008 backend, but I think this is pretty generic problem. For example, we have customer table and we want to provide search functionality to the UI for different parameters, like customer Type, customer State, customer Zip, etc., and all of them are optional and can be selected in any combinations. In other words, the user can search by customerType only or by customerType, customerZIp or any other possible combinations. There are several available design approaches, but all of them have some disadvantages and I would like to ask if there is a preferred design among them or if there is another approach. Generate sql where clause sql statement dynamically in the business tier, based on the search request from the UI, and pass it to a stored procedure as parameter. Something like @Where = ‘where CustomerZip = 111111’ Inside the stored procedure generate dynamic sql statement and execute it with sp_executesql. Disadvantage: dynamic sql, sql injection Implement a stored procedure with multiple input parameters, representing the search fields from the UI, and use the following construction for selecting the records only for the requested fields in the where statement. WHERE (CustomerType = @CustomerType OR @CustomerType is null ) AND (CustomerZip = @CustomerZip OR @CustomerZip is null ) AND ………………………………………… Disadvantage: possible performance issue for the sql. 3.Implement separate stored procedure for each search parameter combinations. Disadvantage: The number of stored procedures will increase rapidly with the increase of the search parameters, repeated code.

• need help understanding a function.

  - by Adam McC

  i had previously asked for help writing/improving a function that i need to calculate a premium based on differing values for each month. the premium is split in to 12 months and earned on a percentage for each month. so if the policy start in march and we are in jan we will have earned 10 months worth. so i need to add up the monthly earning to give us the total earned. wach company wil have differeing earnings values for each month. my original code is Here. its ghastly and slow hence the request for help. and i was presented with the following code. the code works but returns stupendously large figures. begin set @begin=datepart(month,@outdate) set @end=datepart(month,@experiencedate) ;with a as ( select *, case calmonth when 'january' then 1 when 'february' then 2 when 'march' then 3 when 'april' then 4 when 'may' then 5 when 'june' then 6 when 'july' then 7 when 'august' then 8 when 'september' then 9 when 'october' then 10 when 'november' then 11 when 'december' then 12 end as Mnth from tblearningpatterns where clientname=@client and earningpattern=@pattern ) , b as ( select earningvalue, Mnth, earningvalue as Ttl from a where Mnth=@begin union all select a.earningvalue, a.Mnth, cast(b.Ttl*a.earningvalue as decimal(15,3)) as Ttl from a inner join b on a.Mnth=b.Mnth+1 where a.Mnth<=@end ) select @earningvalue= Ttl from b inner join ( select max(Mnth) as Mnth from b ) c on b.Mnth=c.Mnth option(maxrecursion 12) SET @earnedpremium = @earningvalue*@premium end can someone please help me out?

• Help with string equality in Java

  - by annayena

  The following function accepts 2 strings, the 2nd (not 1st) possibly containing *'s (asterisks). An * is a replacement for a string (empty, 1 char or more), it can appear appear (only in s2) once, twice, more or not at all, it cannot be adjacent to another * (ab**c), no need to check that. public static boolean samePattern(String s1, String s2) It returns true if strings are of the same pattern. It must be recursive, not use any loops, static or global variables. Also it's prohibited to use the method equals in the String class. Can use local variables and method overloading. Can use only these methods: charAt(i), substring(i), substring(i, j), length(). Examples: 1: TheExamIsEasy; 2: "The*xamIs*y" ---> true 1: TheExamIsEasy; 2: "Th*mIsEasy*" ---> true 1: TheExamIsEasy; 2: "*" ---> true 1: TheExamIsEasy; 2: "TheExamIsEasy" ---> true 1: TheExamIsEasy; 2: "The*IsHard" ---> FALSE I am stucked on this question for many hours now! I need the solution in Java please kindly help me.

• Hard Drive POV clock

  - by SkinnyMAN

  I am building a hard drive POV clock. (google it, they are pretty cool) I am working on the code for it, right now all i want to do is get the hang of making it do simple patterns with the RGB leds. I am wondering if anyone has any ideas on how to do something simple like make a red line rotate around the platter. right now what i have is an interrupt that triggers a function. int gLED = 8; // pins for RGB led strip int rLED = 9; int bLED = 10; attachInterrupt(0, ledPattern, FALLING); void ledPattern(){ digitalWrite(gLED, HIGH); // This will make a stable image of slice of the delayMicroseconds(500); // platter, but it does not move. digitalWrite(gLED, LOW); } That is the main part of the code (obviously I cut some stuff out that arduino requires) What I am trying to figure out is how can make that slice rotate around the platter. Eventually I will make the pattern more interesting by adding in other colors. Any Ideas?

• Advance Query with Join

  - by user1462589

  I'm trying to convert a product table that contains all the detail of the product into separate tables in SQL. I've got everything done except for duplicated descriptor details. The problem I am having all the products have size/color/style/other that many other products contain. I want to only have one size or color descriptor for all the items and reuse the "ID" for all the product which I believe is a Parent key to the Product ID which is a ...Foreign Key. The only problem is that every descriptor would have multiple Foreign Keys assigned to it. So I was thinking on the fly just have it skip figuring out a Foreign Parent key for each descriptor and just check to see if that descriptor exist and if it does use its Key for the descriptor. Data Table PI Colo Sz OTHER 1 | Blue | 5 | Vintage 2 | Blue | 6 | Vintage 3 | Blac | 5 | Simple 4 | Blac | 6 | Simple =================================== Its destination table is this =================================== DI Description 1 | Blue 2 | Blac 3 | 5 4 | 6 6 | Vintage 7 | Simple ============================= Select Data.Table Unique.Data.Table.Colo Unique.Data.Table.Sz Unique.Data.Table.Other ======================================= Then the dual part of the questions after we create all the descriptors how to do a new query and assign the product ID to the descriptors. PI| DI 1 | 1 1 | 3 1 | 4 2 | 1 2 | 3 2 | 4 By figuring out how to do this I should be able to duplicate this pattern for all 300 + columns in the product. Some of these fields are 60+ characters large so its going to save a ton of space. Do I use a Array?

• Generic Event Generator and Handler from User Supplied Types?

  - by JaredBroad

  I'm trying to allow the user to supply custom data and manage the data with custom types. The user's algorithm will get time synchronized events pushed into the event handlers they define. I'm not sure if this is possible but here's the "proof of concept" code I'd like to build. It doesn't detect T in the for loop: "The type or namespace name 'T' could not be found" class Program { static void Main(string[] args) { Algorithm algo = new Algorithm(); Dictionary<Type, string[]> userDataSources = new Dictionary<Type, string[]>(); // "User" adding custom type and data source for algorithm to consume userDataSources.Add(typeof(Weather), new string[] { "temperature data1", "temperature data2" }); for (int i = 0; i < 2; i++) { foreach (Type T in userDataSources.Keys) { string line = userDataSources[typeof(T)][i]; //Iterate over CSV data.. var userObj = new T(line); algo.OnData < typeof(T) > (userObj); } } } //User's algorithm pattern. interface IAlgorithm<TData> where TData : class { void OnData<TData>(TData data); } //User's algorithm. class Algorithm : IAlgorithm<Weather> { //Handle Custom User Data public void OnData<Weather>(Weather data) { Console.WriteLine(data.date.ToString()); Console.ReadKey(); } } //Example "user" custom type. public class Weather { public DateTime date = new DateTime(); public double temperature = 0; public Weather(string line) { Console.WriteLine("Initializing weather object with: " + line); date = DateTime.Now; temperature = -1; } } }

• Runtime of optimized Primehunter

  - by Setton

  Ok so I need some serious runtime help here! This method should take in an int value, check its primality, and return true if the number is indeed a prime. I understand why the loop only needs to go up to i squared, I understand that the worst case scenario is the case in which either the number is prime (or a multiple of a prime). But I don't understand how to quantify the actual runtime. I have done the loop myself by hand to try to understand the pattern or correlation of the number (n) and how many loops occur, but I literally feel like I keep falling into the same trap every time. I need a new way of thinking about this! I have a hint: "Think about the SIZE of the integer" which makes me want to quantify the literal number of integers in a number in relation to how many iterations it does in the for loop (floor log(n)) +1). BUT IT'S NOT WORKIIIING?! I KNOW it isn't square root n, obviously. I'm asking for Big O notation. public class PrimeHunter { public static boolean isPrime(int n) { boolean answer = (n > 1) ? true : false; //runtime = linear runtime for (int i = 2; i * i <= n; i++) //runtime = ????? { if (n % i == 0) //doesn't occur if it is a prime { answer = false; break; } } return answer; //runtime = linear runtime } }

• Google sheet dynamic WHERE clause for query() statement

  - by jason_cant_code

  I have a data table like so: a 1 a 2 b 3 b 4 c 5 c 6 c 7 I want to pull items out of this table by dynamically telling it what letters to pull. My current formula is: =query(A1:B7,"select * where A ='" & D1 & "'"). D1 being the cell I wish to modify to modify the query. I want to be able input into D1 -- a, a,b, a,b,c and have the query work. I know it would involve or statements in the query, but haven't figured out how to make the formula dynamic. I am looking for a general solution for this pattern: a -- A = 'a' a,b -- A = 'a' or A = 'b' a,b,c -- A = 'a' or A = 'b' or A='c' Or any other solution that solves the problem. Edit: So far I have =ArrayFormula(CONCATENATE("A='"&split(D3,",")&"' or ")) this gives A='a' or A='b' or A='c' or for a,b,c. can't figure out how to remove the last or.

• Eclipc java,writting a program [closed]

  - by ghassar

  I have an important exercise for that i found in the internet please i need help in using eclipc java thanks i have to design, implement, test and document a Java program (a set of classes) for one of the following problem specifications: Problem 1 – Jubilee Estate Agency Property Management System A local Estate Agent would like a prototype system to keep track of properties that are offered for sale. The Estate Agent sells domestic and commercial properties. You will need to define classes that represent the Estate Agency System. You should design your system and the classes that you will need before starting coding. Your system must have a graphical user interface and be designed and developed using the object-oriented principles of the MVC architecture design pattern i.e. the user interface class must be separate from the other classes. The initial basic requirements for the system are as follows: • Include a list of domestic properties for sale that include details of: address, description, selling price, and number of rooms • Include a list of commercial properties for sale that include details of: address, description, selling price, and area in square metres • Enable the properties that are for sale to be viewed on the screen • Allow the customer to select one or more properties to be placed on a ‘viewing list’ so that the properties can be visited in person • Display on the screen the viewing list that shows the details of the properties chosen • Provide a basic search facility to find properties that are for sale in a particular price band and display the results • Enable a property to be marked as sold

• Parallel features in .Net 4.0

  - by Jonathan.Peppers

  I have been going over the practicality of some of the new parallel features in .Net 4.0. Say I have code like so: foreach (var item in myEnumerable) myDatabase.Insert(item.ConvertToDatabase()); Imagine myDatabase.Insert is performing some work to insert to a SQL database. Theoretically you could write: Parallel.ForEach(myEnumerable, item => myDatabase.Insert(item.ConvertToDatabase())); And automatically you get code that takes advantage of multiple cores. But what if myEnumerable can only be interacted with by a single thread? Will the Parallel class enumerate by a single thread and only dispatch the result to worker threads in the loop? What if myDatabase can only be interacted with by a single thread? It would certainly not be better to make a database connection per iteration of the loop. Finally, what if my "var item" happens to be a UserControl or something that must be interacted with on the UI thread? What design pattern should I follow to solve these problems? It's looking to me that switching over to Parallel/PLinq/etc is not exactly easy when you are dealing with real-world applications.

• 100% height for multiple divs

  - by kilrizzy

  I usually have my structure laid out something like this: <div id="all"> <div id="page"> <div id="header"></div> <div id="content"></div> <div id="footer"></div> </div> </div> Where the body will hold a background pattern, "all" will hold a dropshadow for the page going up and down, and "page" may often have a repeating-y background as well. I have tried variations on using the css height/min-height properties: html, body { height:100%; ... } #all { height:100%; min-height:100%; } #page { height:100%; min-height:100%; height:auto !important; } It seems like if I remove height:auto from "all" then it seems like it works UNTIL you scroll, then after the scroll the background for all dissappears example However if I keep the height:auto there then I get the problem of the background for page not working example Hopefully someone knows a fix?

• Openswan + xl2tpd connections time out after a while

  - by Halfgaar

  I have a non-NATed Openswan+xl2tpd server (Ubuntu 12.04), to which I connect with a Windows 8 behind NAT. The client loses its connection after a while of doing nothing (between 30 and 60 minutes, but I didn't time it). The client doesn't have enabled that it should kill inactive connections. Nor does it ever go into sleep mode. I also tried setting the kill-after-time to 24 hours, but that didn't help. The NAT router behind which the client located is Debian Linux, and its router is a Cisco which connects us directly to the data center where the server is. None of our other connections, like SSH, get dropped with inactivity (because of cheap routers). I did however try turning on the keepalives in /etc/ipsec.conf: config setup (...snip...) nat_traversal=yes force_keepalive=yes keep_alive=10 but that didn't help. As you can see in the config later, dead peer detection's action is clear. That would be a first suggestion to fix, but I need clear, because people will be connecting from everwhere but the kitchen sink. Besides, as I said, in the test setup I have now, I can't see any device killing its connection. (edit: 'restart' also has the same effect) These are of one time it happened: Jul 18 16:18:06 host xl2tpd[1918]: Maximum retries exceeded for tunnel 49070. Closing.

• How to manipulate default document with rewrite module on IIS7?

  - by eugeneK

  Until few month ago i've been using IIS 6 where i could add different Default Documents to each websites which are physically same directory. Since II7 which adds Default Document value to web config i couldn't use such technique as web.config was changed for all the directory. So I've found simple solution with rewrite module to change Default Document for each domain <defaultDocument enabled="false" /> <rewrite> <rewriteMaps> <rewriteMap name="ResolveDefaultDocForHost"> <add key="site1.com" value="Default1.aspx" /> <add key="site2.com" value="Default2.aspx" /> </rewriteMap> </rewriteMaps> <rules> <rule name="DefaultDoc Redirect If No Trailing Slash" stopProcessing="true"> <match url=".*[^/]$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" /> </conditions> <action type="Redirect" url="{R:0}/" /> </rule> <rule name="PerHostDefaultDocSlash" stopProcessing="true"> <match url="$|.*/$" /> <conditions> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" /> <add input="{ResolveDefaultDocForHost:{HTTP_HOST}}" pattern="(.+)" /> </conditions> <action type="Rewrite" url="{R:0}{C:1}" appendQueryString="true" /> </rule> </rules> </rewrite> Now i've got two other issues. first of all i can't use canonical url rewrite, if i set one then site1.com and site2.com redirected to www.site1.com instead of having www. for each. second problem is that there is a directory within site1' and site2' physical directory called members in which Default.aspx is always a Default Document doesn't matter which domain name was used. It doesn't work as well. Please help me with this issue because i've never thought i will get such problem with supposed to be better IIS7...

• Some DHCP clients end up with wrong DNS server

  - by Nic Waller

  The scenario: DC running Windows Server 2008 R2 providing DNS + DHCP Cisco 1811 Router as the gateway 30 Windows XP DHCP clients on the LAN The problem: Some workstations are spontaneously switching to an incorrect DNS server. Specifically, ipconfig /all shows that they start using the gateway as a DNS server. This happens about 5-10 times a day to various computers, sometimes more than once per day. The workaround: Repairing the connection on the XP client always fixes the problem, and the correct DNS server address is obtained. We lost our main DNS/DHCP machine a week ago, and had to bring this one online as a spare. We've been having this issue since then. DHCP leases on the old and new servers are configured for "wired" (8 day) duration. There are definitely no other DHCP servers active on the LAN. So far there is no discernible pattern about which clients will show this problem, or when. When I ran DCDIAG /test:DNS it came back clean. Manual inspection of the DNS zone shows that all the records are appearing as expected, with no traces of the previous machine in there. Update Feb 27: Added screenshots. Here is a screenshot of the DHCP scope options on the 2008 R2 server. And here is a screenshot of ipconfig /all running on a healthy host. I don't have any ailing hosts at the moment, but will grab a screencap next time it happens. Update Feb 28: More screenshots. Here's a screenshot of DHCP and DNS traffic from a healthy client when repairing the local area connection. There's definitely only one server responding, but it does seem strange that the negotiation takes place twice. I'll try to get a similar capture from a sick machine this coming week. Update Mar 01: Caught a bad ipconfig. Here's a screenshot of ipconfig /all from a client that had this issue. It says the lease was issued this morning, but it doesn't even have an entry for the secondary DNS I set up yesterday. Both DNS servers were discovered properly when repairing the connection. Update Mar 01: It even got the sysadmin! This issue finally affected my personal workstation this morning. Unfortunately I had just rebooted and wasn't running a packet dump at the time. I set up a secondary server yesterday, and was logging all DNS traffic to it. My machine had not contacted the secondary DNS in over half an hour, so that says to me that it's just spontaneously reverting to the gateway without even failing over to secondary DNS first. Today I swapped the order of the DNS servers in DHCP, so the secondary is primary and vice versa. I will update again once I know how that goes.

• OS X Snow Leopard 10.6 Refuses to Load Websites the first time intermittently

  - by Brandon

  Many times when I am browsing the web, Snow Leopard will sit and load a site for 20 seconds or more, until it times out and says it cannot be displayed. If I refresh, it loads RIGHT away, every time. The issue is intermittent but happens from once every couple of days to a few times a day. So the long and short of it is this: Aluminum MacBook (Non-Pro) 2.4GHz Core2Duo, 4GB DDR3 I am using 10.6.6 but I have had this issue since 10.6.0 It happens in Firefox, Chrome, and Safari I have flushed my DNS (using the command 'blablabla flush') I am using custom DNS servers which I hoped would fix it but it had no effect* I am running Apache currently but haven't been for most of the time I've reformatted multiple times, always experiencing the issue I am on Cox cable internet, with a Motorola Surfboard & a Belkin F6D4230-4 v1 (Pre?) N wireless router. I've put the router in G only & N only & G+N to no effect It seems to be domain dependant as I can sometimes load the Google cache right away, and sometimes other sites will load but Google will refuse My Powerbook G4 with Leopard, other Windows XP laptops, & my wired Win7 desktop do not suffer from the issue. *I recently started using these to escape the awful Cox redirect page on timeouts I'm almost positive the issue has happened on other networks but I can't recall a specific instance (I have a terrible memory). The problem is intermittent and fixable enough (I just have to wait until it times out and hit refresh one time) but incredibly annoying since I'm constantly reading documentation from a large variety of sites. EDIT: To clarify, this happens with ALL sites, not only specific sites. I haven't been able to detect any pattern to the failures, but one day Google.com will refuse to load while reddit.com will, and the next day vice versa. Keep in mind that waiting for a timeout and hitting refresh loads the page right away, every time. If I don't wait for the timeout, opening more links, hitting refresh, and clicking the link a billion times have no effect. It seems to be domain neutral, affecting sites seemingly at random. It doesn't seem to have anything to do with connection inactivity either, because I will be SSHed into different servers, uploading files, browsing, downloading, etc, and it will just quit loading Jquery.com (for example) until I sit and wait for a timeout. /EDIT This is my last resort. Please, someone, tell me what is happening. Thank you.

• apache mod_cache in v2.2 - enable cache based on url

  - by Janning

  We are using apache2.2 as a front-end server with application servers as reverse proxies behind apache. We are using mod_cache for some images and enabled it like this: <IfModule mod_disk_cache.c> CacheEnable disk / CacheRoot /var/cache/apache2/mod_disk_cache CacheIgnoreCacheControl On CacheMaxFileSize 2500000 CacheIgnoreURLSessionIdentifiers jsessionid CacheIgnoreHeaders Set-Cookie </IfModule> The image urls vary completely and have no common start pattern, but they all end in ".png". Thats why we used the root in CacheEnable / If not served from the cache, the request is forwarded to an application server via reverse proxy. So far so good, cache is working fine. But I really only need to cache all image request ending in ".png". My above configuration still works as my application server send an appropriate Cache-Control: no-cache header on the way back to apache. So most pages send a no-cache header back and they get not cached at all. My ".png" responses doesn't send a Cache-Control header so apache is only going to cache all urls with ".png". Fine. But when a new request enters apache, apache does not know that only .png requests should be considered, so every request is checking a file on disk (recorded with strace -e trace=file -p pid): [pid 19063] open("/var/cache/apache2/mod_disk_cache/zK/q8/Kd/g6OIv@woJRC_ba_A.header", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) I don't want to have apache going to disk every request, as the majority of requests are not cached at all. And we have up to 10.000 request/s at peak time. Sometimes our read IO wait spikes. It is not getting really slow, but we try to tweak it for better performance. In apache 2.4 you can say: <LocationMatch .png$> CacheEnable disk </LocationMatch> This is not possible in 2.2 and as I see no backports for debian I am not going to upgrade. So I tried to tweak apache2.2 to follow my rules: <IfModule mod_disk_cache.c> SetEnvIf Request_URI "\.png$" image RequestHeader unset Cache-Control RequestHeader append Cache-Control no-cache env=!image CacheEnable disk / CacheRoot /var/cache/apache2/mod_disk_cache #CacheIgnoreCacheControl on CacheMaxFileSize 2500000 CacheIgnoreURLSessionIdentifiers jsessionid CacheIgnoreHeaders Set-Cookie </IfModule> The idea is to let apache decide to serve request from cache based on Cache-control header (CacheIgnoreCacheControl default to off). And before simply set a RequestHeader based on the request. If it is not an image request, set a Cache-control header, so it should bypass the cache at all. This does not work, I guess because of late processing of RequestHeader directive, see https://httpd.apache.org/docs/2.2/mod/mod_headers.html#early I can't add early processing as "early" keyword can't be used together with a conditional "env=!image" I can't change the url requesting the images and I know there are of course other solutions. But I am only interested in configuring apache2.2 to reach my goal. Does anybody has an idea how to achieve my goal?

• Weird random application hang problem

  - by haridsv

  I am trying to understand an application hang problem that started up lately on my windows xp system. The system runs fine for days (sometimes) without ever shutting down or putting it to sleep, but the problem first shows up as one of the apps hanging. The application's UI stops responding or one or more background threads hang, so even though the GUI is responding, it is not doing anything (e.g., in VirtualDub's case, the UI responds fine, but the job doesn't progress and I won't even be able to abort it). The weirdness part comes from the fact that if I try to kill such an app, the program that is used to kill it goes into the same mode (i.e, that hangs instead of the original). E.g., if I use Process Explorer to kill it, the original program exits, but procexp now hangs. If I use another instance of procexp to kill the one that is hanging, this repeats, so there is always at least one program hanging in that state. This is not specific to procexp, I tried the native task manager and even the "End Process" dialog from windows explorer that shows up when you try to close a non-responsive GUI (in this case, the explorer itself hangs). The only program that didn't hang after the kill, is the command line taskkill. However, in this case, explorer hangs instead of taskkill. Also, once this problem starts manifesting, it soon ends up freezing the whole system to the extent that even a clean shutdown is not possible, so I have learned to reboot as soon as I notice this problem, however this is very inconvenient, as I often have encoding batch jobs going on which can't continue the job after the restart. The longer I leave the system running after seeing this problem, the more applications get into this state. I have tried to do a repair install but that didn't make any difference. I also uninstalled some of the newer installs, but again no difference. I tried to search online, but got inundating results for generic hang and crash related problems. Though I couldn't notice any pattern, it seems as though the problem is more frequent if I have some video encoding going on at that time. I had the system running for days when I only do browsing and internet audio/video chat before I decide to start encoding something and the problem starts to show up. I am not too sure if it is the encoding program that first hangs, though I almost always noticed that too hanging (like the VirtualDub stopping to make progress). I also had to reboot 3 times on one day when I was heavily experimenting with encoding. I would appreciate any help in narrowing down this problem and save me the trouble of reinstalling. I don't especially want to loose my gotd installs.

• Messages stuck in SMTP queue - Exchange 2003

  - by Diav

  I need your help people ;-) I have a problem with messages coming into our Exchange Server and ones going out through it. Basically, the messages are stuck in the SMTP queue. A message will come into the server, I can see it listed under "Exchange System Manager", but if you list the properties of the message queue it says something like 00:10 SMTP Message queued for local delivery 00:10 SMTP Message delivered locally to [email protected] 00:10 SMTP Message scheduled to retry local delivery 00:11 SMTP Message delivered locally to [email protected] 00:11 SMTP Message scheduled to retry local delivery etc etc For outgoing message list looks like this: 10:55 SMTP: Message Submitted to Advanced Queuing 10:55 SMTP: Started Message Submission to Advanced Queue 10:55 SMTP: Message Submitted to Categorizer 10:55 SMTP: Message Categorized and Queued for Routing 10:55 SMTP: Message Routed nad Queued for Remote Delivery And the end - since then status didn't change, message is in queue, I am forcing connection from time to time but without an effect. I checked connection with smarthost (used telnet for that) and everything seems to work correctly, so the problem is probably on exchange side. I am using Exchange Server 2003 running on Small Business Server 2003. I don't have any antivirus installed on server. Remaining free space on each partition is over 3Gb, on partition with data bases - it is over 12Gb. All was working good and without problems since 2005, problems started in half of this june - messages started going out and being stuck almost randomly (I don't see a pattern yet, some are going out, some are not, some are going after several hours). I don't know what to do, what to check more, so please, any ideas? Best regards, D. edit Priv1.edb has 14,5GB and priv1.stm 2,6GB - together those files have more than 16GB - can it be the reason? If yes, then what? Indeed, I haven't thought that it can have something in common with my problem, but several users reported recent problems with Outlook Web Access - they can log in, they see the list of their mails, but they can't see the content of their emails. Although when they are connecting with Outlook 2003/2007 - there is no such problem, only with OWA there is. edit2 So,.. It works now, and I have to admit that I am not really sure what the problem was (hope it won't come back). What have I done: Cleaned up some mailboxes to reduce size of them Dismounted Information Store Defragmentated data base files ( I used eseutil: c:\program files\exchsrvr\bin eseutil /d g:\data base\Exchsrvr\MDBDATA\priv1.edb ) Mounted Information Store back ..and before I managed to do anything else - my queue started moving, elements which were kept there already for days - started moving and after few minutes everything was sent, both, outside and locally. But: priv1.edb is still big (13 884 203 008), priv1.stm as well (2 447 384 576), so this is probably not the issue of size of the file. And if not this, so what was that? And if that was issue of size of the file, then soon it will repeat - is there something I can do to avoid it ?

• How to make a 100% UNIQUE dvd? [closed]

  - by sajawikio

  Is it possible to make a DVD which would be next to impossible to replicate exactly even with special equipment? To be clear, not in the sense of making the data itself resistant to piracy - nothing like that. More like as an analogy to antiques - a reproduction of a furniture would be able to be spotted to a trained eye, that it is not the original. Is it possible to do this for a dvd? Like, say a dvd is copied, even by someone who is trying to use even special equipment and is hypothetically dying to copy the dvd exactly for whatever reason - even such copied dvd would be detectable that it is not exactly the original dvd somehow (as if it were a reproduction of an original antique, but not the original), and would be almost or even preferably impossible to actually copy 100% exact the dvd ever again. Just some ideas below on the sort of thing i might go about doing to do this, but really am not sure how or what programs, media, hardware, etc. would do the trick Not sure what would do the trick -- but for instance do there exist any blank dvd's that already come pre-recorded with some sort of serial number or bar code, or other metadata, or an encrypted hash, or something like that? Maybe any blank dvd will do but i should get a special software to extract hardcoded metadata? If so which software? Or special hardware even maybe? Such dvd which the "secret" can be: Well, to know what the "secret" is and if it is present on the disk, it probably should be readable by some software or maybe a particular hardware (i guess preferably only if some sort of key is known and input into the software, even better, only then such secret data on disk can be read, otherwise nothing shows up and it looks like just a regular disk with no secret on it), and Would be impossible to actually replicate, especially not with regular burning hardware and preferably not at all. Other idea: Is there any special software that can direct the write head of laser to physically "mar" the dvd in such a way that, when played in dvd player, makes a particular visual pattern or something like that, also say the mar itself shows up as faint scratch on disk, but would be impossible for someone to do themselves exactly? EDIT: Also to clarify suppose the dvd contains video and music that should be playable on dvd players, maybe a menu too (i.e not a dvd containing software), and also to clarify the question is about how to make dvd 100% unique, not how to make the actual content of dvd protected from "piracy".

These are the IP addresses assigned manually to each network adapter. How do I specify these addresses in TTCP? There is also the IPERF tool which has the -B option. Unfortunately I've been only able to use this option to bind the server to the 10.1.1.1 address. I was unable to bind the client to the 10.1.1.2 address. I might be doing it wrong. Can the -B option be used for both the server as well as the client side? What does the syntax look like for the client?

• Skipping scheduled self-tests and predicting drive EOL

  - by Steve Madsen

  For a few weeks now, smartd has been reporting that it is skipping some of its scheduled self-tests on the weekends: Apr 24 18:29:32 calvin smartd[4758]: Device: /dev/sda, skip scheduled Offline Immediate Test; 40% remaining of current Self-Test. Apr 24 18:29:33 calvin smartd[4758]: Device: /dev/sdb, skip scheduled Offline Immediate Test; 50% remaining of current Self-Test. The drives in this RAID-1 array are set to run an offline test four times a day, a short self-test at 2am every day, and a long self-test on Saturdays at 2am. For some reason, it looks like the long self-test is taking longer, causing the other scheduled tests to be skipped. First question: is this a sign of likely drive failure? Then today, smartd reported that a self-test failed.

SMART doesn't seem to get much respect as a reliable way to predict drive failure. What else can I use to get an early indication of drive failure?

• How to move a ruby on rails application to a new server

  - by ManiacZX

  I have a rails app on an old Ubuntu server I need to move onto a new machine. I haven't worked with ruby on rails so I don't really know anything about the structure of the app. I want to load this onto an Ubuntu 8.04 AMI on Amazon EC2 and am looking for any information regarding the migration process such as: Do I copy over the entire folder defined as the application root in the mongrel config (for ex: /u/apps/myapp/current) or just certain folders? Am I looking for trouble if I go with the latest versions of ruby and the various gems? Any general gotchas to look out for in the process. Current server information: root@webnode001:/# cat /proc/version Linux version 2.6.15-27-server (buildd@terranova) (gcc version 4.0.3 (Ubuntu 4.0.3-1ubuntu5)) #1 SMP Fri Dec 8 18:43:54 UTC 2006 root@webnode001:/# rails -v Rails 1.2.3 root@webnode001:/# mongrel_rails cluster::configure --version Version 1.0.1 root@webnode001:/# gem -v 0.9.0 root@webnode001:/# gem list -l *** LOCAL GEMS *** actionmailer (1.3.3, 1.2.5) Service layer for easy email delivery and testing. actionpack (1.13.3, 1.12.5) Web-flow and rendering framework putting the VC in MVC. actionwebservice (1.2.3, 1.1.6) Web service support for Action Pack. activerecord (1.15.3, 1.15.2, 1.14.4) Implements the ActiveRecord pattern for ORM. activesupport (1.4.2, 1.4.1, 1.3.1) Support and utility classes used by the Rails framework. cgi_multipart_eof_fix (2.1) Fix an exploitable bug in CGI multipart parsing which affects Ruby <= 1.8.5 when multipart boundary attribute contains a non-halting regular expression string. daemons (1.0.7, 1.0.5, 1.0.4, 1.0.2) A toolkit to create and control daemons in different ways eventmachine (0.7.2, 0.7.0) Ruby/EventMachine socket engine library fastercsv (1.2.0, 1.1.0) FasterCSV is CSV, but faster, smaller, and cleaner. fastthread (1.0) Optimized replacement for thread.rb primitives ferret (0.11.4) Ruby indexing library. gem_plugin (0.2.2, 0.2.1) A plugin system based only on rubygems that uses dependencies only mongrel (1.0.1, 0.3.13.4) A small fast HTTP library and server that runs Rails, Camping, Nitro and Iowa apps. mongrel_cluster (0.2.1) Mongrel plugin that provides commands and Capistrano tasks for managing multiple Mongrel processes. mysql (2.7) MySQL/Ruby provides the same functions for Ruby programs that the MySQL C API provides for C programs. piston (1.3.3) Piston is a utility that enables merge tracking of remote repositories. rails (1.2.3, 1.1.6) Web-application framework with template engine, control-flow layer, and ORM. rake (0.7.3, 0.7.1) Ruby based make-like utility. sources (0.0.1) This package provides download sources for remote gem installation swiftiply (0.5.1) A fast clustering proxy for web applications.
