  • How do I output Unicode characters as a pair of ASCII characters?

    - by ChrisF
    How do I convert (as an example): Señor Coconut Y Su Conjunto - Introducciõn to: Señor Coconut Y Su Conjunto - Introducciõn I've got an app that creates m3u playlists, but when the track filename, artist or title contains non ASCII characters it doesn't get read properly by the music player so the track doesn't get played. I've discovered that if I write the track out as: #EXTINFUTF8:76,Señor Coconut Y Su Conjunto - Introducciõn #EXTINF:76,Señor Coconut Y Su Conjunto - Introducciõn #UTF8:01-Introducciõn.mp3 01-Introducciõn.mp3 Then the music player will read it correctly and play the track. My problem is that I can't find the information I need to be able to do the conversion properly.

  • C#:multicolumn sorting of datagrid view

    - by Bi
    I have a datagridview in a windows form with 3 columns: Serial number, Name and Date-Time. The Name column will always have either of the two values: "name1" or "name2". I need to sort these columns such that the grid displays all the rows with name values in a specific order (first display all the "name1" rows and then all the "name2" rows). Within the "name1" rows, I want the rows to be sorted by the Date-Time. Please note programmatically, all the 3 columns are strings. For example, if I have the rows: 01 |Name1 | 2010-05-05 10:00 PM 02 |Name2 | 2010-05-02 08:00 AM 03 |Name2 | 2010-05-01 08:00 AM 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM needs to be sorted as 04 |Name1 | 2010-05-01 11:00 AM 05 |Name1 | 2010-05-04 07:00 AM 01 |Name1 | 2010-05-05 10:00 PM 03 |Name2 | 2010-05-01 08:00 AM 02 |Name2 | 2010-05-02 08:00 AM I am not sure how to go about using the below: myGrid.Sort(.....,ListSortDirection.Ascending)

  • Need a regular expression for an Irish phone number

    - by Eoghan O'Brien
    I need to validate an Irish phone number but I don't want to make it too user unfriendly, many people are used to writing there phone number with brackets wrapping their area code followed by 5 to 7 digits for their number, some add spaces between the area code or mobile operator. The format of Irish landline numbers is an area code of between 1 and 4 digits and a number of between 5 to 8 digits. e.g. (021) 9876543 (01)9876543 01 9876543 (0402)39385 I'm looking for a regular expression for Javascript/PHP. Thanks.

  • Binning into timeslots - Is there a better way than using list comp?

    - by flyingcrab
    I have a dataset of events (tweets to be specific) that I am trying to bin / discretize. The following code seems to work fine so far (assuming 100 bins): HOUR = timedelta(hours=1) start = datetime.datetime(2009,01,01) z = [dt + x*HOUR for x in xrange(1, 100)] But then, I came across this fateful line at python docs 'This makes possible an idiom for clustering a data series into n-length groups using zip(*[iter(s)]*n)'. The zip idiom does indeed work - but I can't understand how (what is the * operator for instance?). How could I use to make my code prettier? I'm guessing this means I should make a generator / iterable for time that yields the time in graduations of an HOUR?

  • JQuery Syntax Problem?

    - by Michael Smith
    I am using JQuery to insert divs into a page but i cant seem to get the quotation marks correctly setup. For example the code below works fine: var newDiv_1 = '<div id="event_1"><b>Hello World 01</b></div>'; $('#mon_Events').append(newDiv_1); But when i try to use variable in place of the normal text, i doesnt seem to work: var eventname = 1; var newDiv_1 = '<div id="event_' . eventName . '"><b>Hello World 01</b></div>'; $('#mon_Events').append(newDiv_1); How do i use variable inside this statement?

  • Trying to figure out how to check a checksum

    - by rross
    I'm trying to figure out how to check a checksum. My message looks like this: 38 0A 01 12 78 96 FE 00 F0 FB D0 FE F6 F6 being the checksum. I convert the preceding 12 sets in to binary and then add them together. Then attempt a bitwise operation to apply the 2s complement. I get a value of -1562, but I can't convert it back to hex to check if the value is correct. Can someone point me in the right direction? my code: string[] hexValue = {"38", "0A", "01", "12", "78", "96", "FE", "00", "F0", "FB", "D0", "FE"}; int totalValue = 0; foreach(string item in hexValue) { totalValue += Int32.Parse(item, NumberStyles.HexNumber); } int bAfter2sC = ~totalValue + 1; Console.Write("answer :" + bAfter2sC + "\n");

  • SVNServ deny write access to a directory via wildcard match.

    - by Wes
    Hi, We have a requirement that every piece of code that makes it into production will be reviewed by a senior developer. The way I have envisioned this working is by a naming convention for branches that regular developers cannot check code into. Following the SVN recomended directory structure this translates into something like. [project-name]/trunk/ [project-name]/branches/ [project-name]/branches/development-01 [project-name]/branches/development-02 [project-name]/branches/task-increasefontsize [project-name]/branches/release-01 [project-name]/branches/release-02 [project-name]/tags/ So in the authz file I would like to have something like the following [/] @developers = rw [/*/branches/release-*] @developers = r @senior_developers = rw However I can't find any evidence that SVN supports * (or any other wildcard character). Is such a thing possible or do I need a pre-commit hook?

  • CRC32 calculations for png chunk doesn't match the real one

    - by user2507197
    I'm attempting to mimic the function used for creating CRC's in PNG files, I'm using the autodin II polynomial and the source code from: http://www.opensource.apple.com/source/xnu/xnu-1456.1.26/bsd/libkern/crc32.c My tests have all been for the IHDR chunk, so my parameters have been: crc - 0xffffffff and 0 (both have been suggested) buff - the address of the IHDR Chunk's type. length - the IHDR Chunk's length + 4 (the length of the chunk's data + the length of the type) I printed the calculated CRC in binary, which I compared to the actual CRC of the chunk. I can see no similarities (little-big endian, reversed bits, XOR'd, etc). This is the data for the IHDR chunk (hexadecimal format): length(big endian): d0 00 00 00 (13) type: 49 48 44 52 data: 00 00 01 77 00 00 01 68 08 06 00 00 00 existing CRC: b0 bb 40 ac If anyone can tell me why my calculations are off, or give me a CRC32 function that will work I would greatly appreciate it. Thank-you!

  • What is the most effective and flexible way to generate combinations in TSQL?

    - by SDReyes
    What is the most effective and flexible way to generate combinations in TSQL? With 'Flexible', I mean you should be able to add easily combination rules. e.g.: to generate combinatories of 'n' elements, sorting, remove duplicates, get combinatories where each prize belongs to a different lottery, etc. For example, Having a set of numbers representing lottery prizes. Number | Position | Lottery --------------------------- 12 | 01 | 67 12 | 02 | 67 34 | 03 | 67 43 | 01 | 89 72 | 02 | 89 33 | 03 | 89 (I include the position column because, a number could be repeated among different lottery's prizes) I would like to generate combinatories like: Numbers | Lotteries ------------------- 12 12 | 67 67 12 34 | 67 67 12 34 | 67 67 12 43 | 67 89 12 72 | 67 89 12 33 | 67 89 . . .

  • Lighttpd + fastcgi + python (for django) slow on first request

    - by EagleOne
    I'm having a problem with a django website I host with lighttpd + fastcgi. It works great but it seems that the first request always takes up to 3seconds. Subsequent requests are much faster (<1s). I activated access logs in lighttpd in order to track the issue. But I'm kind of stuck. Here are logs where I 'lose' 4s (from 10:04:17 to 10:04:21): 2012-12-01 10:04:17: (mod_fastcgi.c.3636) handling it in mod_fastcgi 2012-12-01 10:04:17: (response.c.470) -- before doc_root 2012-12-01 10:04:17: (response.c.471) Doc-Root : /var/www 2012-12-01 10:04:17: (response.c.472) Rel-Path : /finderauto.fcgi 2012-12-01 10:04:17: (response.c.473) Path : 2012-12-01 10:04:17: (response.c.521) -- after doc_root 2012-12-01 10:04:17: (response.c.522) Doc-Root : /var/www 2012-12-01 10:04:17: (response.c.523) Rel-Path : /finderauto.fcgi 2012-12-01 10:04:17: (response.c.524) Path : /var/www/finderauto.fcgi 2012-12-01 10:04:17: (response.c.541) -- logical -> physical 2012-12-01 10:04:17: (response.c.542) Doc-Root : /var/www 2012-12-01 10:04:17: (response.c.543) Rel-Path : /finderauto.fcgi 2012-12-01 10:04:17: (response.c.544) Path : /var/www/finderauto.fcgi 2012-12-01 10:04:21: (response.c.128) Response-Header: HTTP/1.1 200 OK Last-Modified: Sat, 01 Dec 2012 09:04:21 GMT Expires: Sat, 01 Dec 2012 09:14:21 GMT Content-Type: text/html; charset=utf-8 Cache-Control: max-age=600 Transfer-Encoding: chunked Date: Sat, 01 Dec 2012 09:04:21 GMT Server: lighttpd/1.4.28 I guess that if there is a problem, it's whith my configuration.

  • Prevent printing -0

    - by fishinear
    If I do the following in Objective-C: NSString *result = [NSString stringWithFormat:@"%1.1f", -0.01]; It will give result @"-0.0" Does anybody know how I can force a result @"0.0" (without the "-") in this case? EDIT: I tried using NSNumberFormatter, but it has the same issue. The following also produces @"-0.0": double value = -0.01; NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init]; [numberFormatter setNumberStyle:NSNumberFormatterDecimalStyle]; [numberFormatter setMaximumFractionDigits:1]; [numberFormatter setMinimumFractionDigits:1]; NSString *result = [numberFormatter stringFromNumber:[NSNumber numberWithDouble:value]];

  • Replace String pattern in Java

An the content in-between "{ }" should remain unchanged: Ex: \\d{4} after replacing -> NCHAR(0x7B) 4 NCHAR(0x7D). Is there a way to do this using Regular Expressions in Java?. Anyway, this can be done processing the whole string using string operations.

  • Convert hex to decimal keeping fractional part in Lua

    - by Zack Mulgrew
    Lua's tonumber function is nice but can only convert unsigned integers unless they are base 10. I have a situation where I have numbers like 01.4C that I would like to convert to decimal.

  • What would be the best approach to finding a date in a freeform text?

    - by Matthew DeVos
    What would be the best approach to finding a date in a freeform text? A post where a user may place a date in it in several different ways such as: July 14th & 15th 7/14 & 7/15 7-14 & 7-15 Saturday 14th and Sunday 15th Saturday July 14th and 15th and so on. Is regex my best choice for this type of thing with preg_match? I would also like to search if there are two dates, one for a start date and a second for an end date, but in the text I'm searching there may be one date or two. This is my PHP code so far: $dates1 = '01-01'; $dates2 = 'July 14th & 15th'; $dates3 = '7/14 & 7/15'; $dates4 = '7-14 & 7-15'; $dates5 = 'Saturday 14th and Sunday 15th'; $dates6 = 'Saturday July 14th and 15th'; $regexes = array( '/\s(1|2|3|4|5|6|7|8|9|10|11|12)\/\d{1,2}/', //finds a date '/\s(1|2|3|4|5|6|7|8|9|10|11|12)-\d{1,2}/', //finds another date '%\b(0?[1-9]|[12][0-9]|3[01])[- /.](0?[1-9]|1[012])\b%', //finds date format dd-mm or dd.mm ); foreach($regexes as $regex){ preg_match($regex,$dates,$matches); } var_dump($matches);

  • Graphing special functions in Matlab (2D Bessel)

    - by favala
    I'm trying to essentially get something like this where I can see clear ripples at the base but otherwise it's like a Gaussian: This is kind of unsatisfactory because the ripples aren't very noticeable, it has a very gritty quality that obscures the image a bit, and if you move the graph so that it's just in 2D (so it looks like a circle) I'm not even sure if it's quite like how it should be (the concentric circles seem to be more evenly spaced in the real thing). So, is there a better way to do this? a = 2*pi; [X Y] = meshgrid(-1:0.01:1,-1:0.01:1); R = sqrt(X.^2+Y.^2); f = (2*besselj(1,a*R(:))./R(:)).^2; mesh(X,Y,reshape(f,size(X))); axis vis3d;

  • What is the best way to restore(rollback) data in an application to a specified state(date) ?

    - by panzerschreck
    Hello, An example would set the context right, the example below captures the various states of the entity, which needs to be reverted(rolled back) . State 1 - Recorded on 01-Mar-2010 Column1 Column2 Data1 0.56 State 2 - Recorded on 02-Mar-2010 Column1 Column2 Data1 0.57 State 3 - Recorded on 03-Mar-2010 Column1 Column2 Data1 0.58 User notices that state3 is not what he intended to be in, decides to revert back to state2. One approach that I can think of, without modifying the entity is via "auditing" all the inserts/updates, as below, the rollback information captures the data just before the updates/modifications on the entity, so that it can be applied in an order when you need to revert.Please note that changing the entity's schema, is not an option. Rollback - R1 recorded on 01-Mar-2010 Column1 Column2 Data1 0.56 Rollback - R2 Recorded on 02-Mar-2010 Column1 Column2 Data1 0.56 Rollback - R3 Recorded on 03-Mar-2010 Column1 Column2 Data1 0.57 So, to get to state2 , we would start with rollback information R1,apply R2 onto it. Is there a better approach to achieve this ? Thanks for your time.

  • ruby convert hundredth seconds to timestamp optimization

    - by Nik
    Hey! I want to convert "123456" to "00:20:34.56" where the two digits to the right of the decimal point is in hundredth of a second. So 00:00:00.99 + 00:00:00.01 = 00:00:01.00 What I have: def to_hmsc(cent) h = (cent/360000).floor cent -= h*360000 m = (cent/6000).floor cent -= m*6000 s = (cent/100).floor cent -= s*100 "#{h}:#{m}:#{s}.#{s}" end does this: to_hmsc("123456") #= "0:20:34.56" Question 1: I mean,this is ruby, I find the part ' cent -=... ' rather clunky. Can you see any way to shorten the entire process? Question 2: This has been asked a million times before, but please share whatever you've got: what's the shortest way to add leading zero to the digits. so that to_hmsc("123456") #= "00:20:34.56" Thanks!
