  • Looking for fast "Find in Files" program

    - by Josh McDonald
    I currently have a directory with 98,000 individual archive transaction files. I need to search those files for user input strings and have the option to open the files as it finds them or at the end of the search. I'm using Notepad++ currently and, while functional, it's quite slow. I thought about writing my own, but I am only familiar with .NET and I'm a beginner. Also, I'm not sure how efficient that would be compared to NP++. This tool would be used again and again so the dev time would definitely be worth it if it came to that. Is there some other tool out there that's already developed that would accomplish this?

  • fast way for finding GUIDs.

    - by Behrooz
    hi. I have lots(+2000) of GUIDs(in some network class) and my program must find one of them when it receives a message and do the job associated with it. the positive point is i have a hard-code generator, but the fastest way is my goal(and i don't know how to implement it). my code should do something like this: switch(received guid) { case guid1: do job 1; break; case guid2: do job 2; break; case guid3: do job 3; break; case guid4: do job 4; break; .... }

  • How to deal with lots of brackets in a formula?

    - by wenlibin02
    Say, I have a formula like this (in LaTeX or Maple or other text system): Result: ((6*(k2+k3))*A123*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2+6*A12*(-k3+k2)*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*(exp(-k2*(k2^2*t-x)))^2+(-(6*(-k3+k2))*A13*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*(exp(-k3*(k3^2*t-x)))^2-(6*(k2+k3))*k2*k3*(A12*A13*k2^2-2*A12*A13*k2*k3+A12*A13*k3^2-A123*k2^2-2*A123*k2*k3-A123*k3^2)*exp(-k3*(k3^2*t-x)))*exp(-k2*(k2^2*t-x)) Note: the above formula is only one part of the result of a maple calculation, I just can't break them up because there are so many many terms. Apparently, It's very hard to read. What I want to do is to fold the matched brackets level by level. If all the brackets are folded, I can find out clearly how many terms there are. Then I can analyze from the top level to the details of every term. But I just don't know how to realize that. Maybe there are some existed software which can visualize this kind of complex formula. Any idea? P.S. I use Linux system. The open source alternatives are better.

  • complex mysql rank !

    - by silversky
    I have a tb with this col: ein, los, id ... I whant to order the table by this index: win / ( win + los ) * 30 + win / SUM(win) * 70 and then to find the rank for two id's. I'm not very good on mysql, so whath I wrote it's totally wrong: $stmt=$con-prepare("SET @rk := 0"); $stmt=$con-prepare("SELECT rank, id FROM ( SELECT @rk := @rk + 1 AS rank, (win/(win+los)*30+win/SUM(win)*70) AS index, win, los, id FROM tb_name ORDER BY index DESC) as result WHERE id=? AND id=?"); $stmt - bind_param ("ii", $id1, $id2); $stmt - execute(); $stmt - bind_result($rk, $idRk); And also this query it supouse to run maybe every 5-10 sec for every user, so I'm trying to find something very, very fast. if it's necesary I could add, change, delete any column, in order to be as faster as posible.

  • Which has been the most reliable, fastest Windows C++ profiler that you have used?

    - by carleeto
    I need to profile a real time C++ app on Windows. Most of the available profilers are either terribly expensive, total overkill, or both. I don't need any .NET stuff. Since it is a real time app, I need the profiler to be as fast as possible. It would be excellent if it integrated in some way with Visual Studio 2005/2008, but that's not necessary. If this description reminds you of a profiler that you have used, I would really like to know about it. I am hoping to draw from people's use of C++ profilers on Windows to pinpoint one that will do the job. Thanks.

    Trying to know what is the best of my flash memories to use ReadyBoost I realize that I don't know how much of fast flash memory each of my flash drives have. One can read: In some situations, you might not be able to use all of the memory on your device to speed up your computer. For example, some flash memory devices contain both slow and fast flash memory, but ReadyBoost can only use fast flash memory to speed up your computer.

  • Why is writing to my external hard drive slow, while benchmarks show fast writing?

    - by matix2267
    I have an iOmega eGo 320GB portable drive connected through USB2.0 to my laptop running Windows Vista. It's been working fine for quite some time until recently it became very slow when writing e.g. when copying ~300MB movie over to the drive at first it is extremely fast but it actually doesn't write it only puts in cache and then hangs on last 10-20MBs for about a minute. When copying larger files it's the same story: starts fast but then slows down to ~5MB/s (sometimes even slower down to 2MB/s). Strange thing is that I have always had caching disabled for this drive (it was disabled by default and I never bothered changing it). At first I thought that the disk is dying so I checked S.M.A.R.T. values and everything is fine there. I also run chkdsk and it seemed to fix the problem - it worked fast for a few minutes but then it slowed down again. I also tried plugging it into another USB port - no difference. Additionally I noticed that reading under certain circumstances is sometimes slower e.g. loading times for some games are ~10 times longer, whereas simple copying files from this drive to my internal HDD is fast. I ran a speed benchmark using CrystalDiskMark with a 5x100MB run and strangely got these results: read write (MB/s) Seq 33.05 28.25 512k 17.30 15.27 4k 0.267 0.372 4kQD32 0.510 0.260 This is different from what most other people have (I've found many threads about slow disk write while googling but all of them were slow on benchmarks too) which is why I decided to post this problem here. BTW most of the time when writing (or sometimes reading) the activity led is mostly idle (blinks a while and then stops for longer, sometimes has slower blinks ~1 sek, sometimes goes off for a few seconds - extremely long blink :) ) but when benchmarking, defragmenting or just reading (copying from this drive, installing apps from installers there, watching HD videos) it is blinking really fast (like it should) and there are no slowdowns. It shouldn't be driver issue unless stock Windows drivers have some issues I'm not aware of.

  • How to increase fast-forward/rewind on Vista Media Center recorded TV shows?

    - by jtimberman
    How do I granularly increase the various fast-forward/rewind speed/rate for each of the speed settings for skipping through commercials? The current defaults go from barely faster than playback, too fast for unexpectedly short commercials, to omfg its so fast I can't see what is happening. Do people suffer with these defaults, or is there some better setting in the registry, or elsewhere?

  • What factors help in getting a site indexed by Google fast?

    - by ekaj
    What should I do to get a site indexed on Google, fast? Taking example of Super User I just did a quick Google for a question that was 20 minutes old, to look for an answer, and it was already on Google Search - how is this possible? I glanced over this article which seems to suggest that SU has added RSS feeds (which SU has, but when I opened the feed the article says last posted 6 minutes ago, but when Googled it is 11 hours old) - which leads me to think (Based on that article, I don't know much about search indexing but I am reading at the moment) that most of this indexing is done thanks to the sitemap. is there anything else I am unaware of that helps SU questions get on Google so fast?

  • How to copy a cell's formatting using a formula?

    - by Alvin Lim
    For example, cell A1 contains the text "Hello World" which is in bold. In cell A2, I use the formula =A1. Therefore cell A2 now also contains "Hello World", but it is not in bold. How can I modify the formula to also copy the formatting (in this case, bold) of A1? A more complex example is strikethrough properties, i.e. A1 contains "Orange/Red". How do I show the same content in cell A2 dynamically, so that any changes made in A1 will update A2 as well?

  • Can I reactivate the cursor keys for modifying a cell reference in a formula?

    - by Jonas Heidelberg
    When I enter an Excel formula by hand avoiding the mouse, I can conveniently reference cells by using the arrow keys (-,<- etc.). For example, I can enter the formula =A2&B2 in cell C2 by entering =<-&<-<- The result looks like this: If I want to change from B2 to B3, I can just press the downward arrow on the keyboard at this time. How do I do the same thing later, after having left this cell (e.g. by pressing Enter)? In other words, how do I get the flashing dashed line back when re-entering a cell with F2?

  • Ask the Readers: How Fast is Your Internet Connection?

    - by Mysticgeek
    The federal government recently announced a broadband initiative that calls for 260 million homes to have 100Mbps Internet connections by the year 2020. This got us wondering, how fast is your current Internet connection? Photo by roland When it comes to the speed of our Internet connection, we all want the maximum possible. The FCC recently announced their National Broadband Plan, which is an initiative to improve the Internet infrastructure in the United States and provide higher speeds to everyone. You’ve also undoubtedly heard the news about Google getting into the mix with their program to bring ultra high-speed fiber broadband to 50,000 users in select cities. While we wait for those programs to come into fruition, we thought it would be cool to check out what kinds of speeds you’re getting now. Test Your Internet Connection Speed There are several sites out there you can use to test your Internet speeds, but probably the best site is Speedtest.net. It’s easy to use, and allows you test download and upload speeds to and from various locations in the US and throughout the world. If you already know the speeds you’re getting leave a comment and let us know. If you use Speedtest.com, just keep in mind that our comment system won’t allow you to copy their result links, but you can simply tell us what you get in the results. We’re especially interested in the results of those of you who have Verizon FIOS or Comcast’s “Ultra” service. Leave a comment and join in the discussion!

  • I want to be a programmer, work in corporate environment, earn well, learn fast and eventually become a great programmer [on hold]

    - by Shin San
    I'll try to keep this simple: I'm 29, been dabbling with computers for the past 10 years, had entry level jobs in tech support for different apps, been fixing computers for a while and now want to specialize in something. I'm not 100% stranger to programming but haven't gone past if/then/else with anything. A bit of JavaScript, PHP, Python and currently checking out the "SELECT" statement in SQL :)) I'm curious about programming, I enjoy it and I'm thinking of making a living out of it. So, while I'm at it, why not earn a bit more than the average Joe? So, that's why I'm checking what the best solution, the best learning path and the most useful languages are considering: a) how easy/fast can you find a job by knowing it b) how much would I be able to earn c) how fast can I learn it By reading 10-20 articles online I've come up with an example, but I'm here for some expert advice. Example: * ratings from a) and b) point of view #1 sql ; #2 java ; #3 html (please don't start the markup language debate) ; #4 javascript From this ratings, I'd say a good way to go is learn html/css/(javascript or php) for the web part of apps, some SQL/MySQL/whateverSQL for holding data and loads of Java for the program itself. Please let me know if this is a good idea and if so, what should be the order for learning all of the above. Else, please let me know a better way and why it would be better. Many thanks for taking the time to read my question. Best wishes to you guys Edit: if I think Java + SQL + HTML&JavaScript is the way to go, does the order I'm learning them in matter? Or can I try to learn them all at once?

  • What are the hard and fast rules for Cache Control?

    - by Metalshark
    Confession: sites I maintain have different rules for Cache Control mostly based on the default configuration of the server followed up with recommendations from the Page Speed & Y-Slow Firefox plug-ins and the Network Resources view in Google's Speed Tracer. Cache-Control is set to private/public depending on what they say to do, ETag's/Last-Modified headers are only tinkered with if Y-Slow suggests there is something wrong and Vary-Accept-Encoding seems necessary when manually gziping files for Amazon CloudFront. When reading through the material on the different options and what they do there seems to be conflicting information, rules for broken proxies and cargo cult configurations. Any of the official information provided by the analysis tools mentioned above is quite inaccessible as it deals with each topic individually instead of as a unified strategy (so there is no cross-referencing of techniques). For example, it seems to make no sense that the speed analysis tools rate a site with ETag's the same as a site without them if they are meant to help with caching. What are the hard and fast rules for a platform agnostic Cache Control strategy? EDIT: A link through Jeff Atwood's article explains Caching in superb depth. For the record though here are the hard and fast rules: If the file is Compressed using GZIP, etc - use "cache-control: private" as a proxy may return the compressed version to a client that does not support it (the browser cache will hold files marked this way though). Also remember to include a "Vary: Accept-Encoding" to say that it is compressible. Use Last-Modified in conjunction with ETag - belt and braces usage provides both validators, whilst ETag is based on file contents instead of modification time alone, using both covers all bases. NOTE: AOL's PageTest has a carte blanche approach against ETags for some reason. If you are using Apache on more than one server to host the same content then remove the implicitly declared inode from ETags by excluding it from the FileETag directive (i.e. "FileETag MTime Size") unless you are genuinely using the same live filesystem. Use "cache-control: public" wherever you can - this means that proxy servers (and the browser cache) will return your content even if the rest of the page needs HTTP authentication, etc.

  • faster way to draw an image

    - by iHorse
    im trying to combine two images into a single image. unfortunately this has to be done very quickly in response to a user sliding a UISlider. i can combine the two images into a single image no problem. but the way I'm doing it is horribly slow. the sliders stick and jump rather frustratingly. i don't think i can throw the code into a background thread because i would run out of threads to quickly. i haven't actually tired that yet. below is my code. any ideas on how to speed it up would be helpful. UIGraphicsBeginImageContext(CGSizeMake(bodyImage.theImage.image.size.width * 1.2, bodyImage.theImage.image.size.height * 1.2)); [bodyImage.theImage.image drawInRect: CGRectMake(-2 + ((bodyImage.theImage.image.size.width * 1.2) - bodyImage.theImage.image.size.width)/2, kHeadAdjust, bodyImage.theImage.image.size.width * bodyImage.currentScale, bodyImage.theImage.image.size.height * bodyImage.currentScale)]; if(isCustHead) { [Head.theImage.image drawInRect: CGRectMake((bodyImage.theImage.image.size.width * 1.2 - headWidth)/2 - 11, 0, headWidth * 0.92, headWidth * (Head.theImage.image.size.height/Head.theImage.image.size.width) * 0.92)]; } else { [Head.theImage.image drawInRect: CGRectMake((bodyImage.theImage.image.size.width * 1.2 - (headWidth * defaultHeadAdjust))/2 - 10, 0, (headWidth * defaultHeadAdjust * 0.92), (headWidth * defaultHeadAdjust) * (Head.theImage.image.size.height/Head.theImage.image.size.width) * 0.92)]; } drawSurface.theImage.image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();

  • C++: Best text accumulator

    - by MInner
    Text gets accumulates piecemeal before being sent to client. Now we use own class that allocates memory for each piece as char massive. (Anyway, works like char[][] + std::list<char*>). Then we build the whole string, convert it into std::sting and then create boost::asio::streambuf using it. That's slow enough, I assume. Correct me if I'm wrong. I know, in many cases simple FILE type from stdio.h is used. How does it works? Allocates memory at every write into it. So, is it faster and is there any way to read into boost::asio::streambuf from FILE?
