  • Undead Windows 7 service

    - by Jan
    I created a Windows 7 service in Visual Studio 2010. Test install crashed and left lots of debris: service shows in the list of services but will not start ('Referenced file does not exist'), is impossible to uninstall ('Action valid only for services that are installed') and is not shown in the Programs and Features aplet. Is there a list of installed services that I could hack? Thanks, Jan

like PersonalInfo,contactInfo,Address there will be only one record, but for tags like "OtherInfo","academicInfo","ProfessionalInfo" there will be multiple records so in xml there are tags for that. now to edit tags having one record only for one user i did coding like: private void FillFamilyInfoControls(XElement rootElement) { ddlSunsign.DataBind(); XElement parentElement; string xPathQuery = "FamilyInfo/Fields"; parentElement = rootElement.XPathSelectElement(xPathQuery); txtGallantryHistory.Text = parentElement.Element("GallantryHistory").Attribute("value").Value; txtEthinicity.Text = parentElement.Element("Ethinicity").Attribute("value").Value; txtKulDev.Text = parentElement.Element("KulDev").Attribute("value").Value; txtKulDevi.Text = parentElement.Element("KulDevi").Attribute("value").Value; txtCaste.Text = parentElement.Element("Caste").Attribute("value").Value; ddlSunsign.SelectedValue = parentElement.Element("SunSignId").Attribute("value").Value; ddlSunsign.SelectedItem.Text = parentElement.Element("SunSignName").Attribute("value").Value; } private XElement UpdateFamilyInfoXML(XElement rootElement) { XElement parentElement; string xPathQuery = "FamilyInfo/Fields"; parentElement = rootElement.XPathSelectElement(xPathQuery); parentElement.Element("GallantryHistory").Attribute("value").Value = txtGallantryHistory.Text; parentElement.Element("Ethinicity").Attribute("value").Value = txtEthinicity.Text;

UMSession.CurrentLoggedInUser.UserId.ToString(); parentElement.Element("ModifiedOn").Attribute("value").Value = System.DateTime.Now.ToString(); return rootElement; //rootElement.XPathSelectElement(xPathQuery) = parentElement; } these 2 functions i have used to update xml and to get data from xml and fill into controls. but for the tags where there are multiple records... i am not able to find any solution /control using which i an do it easily. coz my field's value is in attribute named "Value" when in the examples i saw its between opening and closing tag.. i have 2 methods to do so. 1 . i make one page to edit a single record and pass id of record to that page on editing. open the page in iframe on same page to edit and in page_load get data from database for id passed and fill it in control. 2 . i store xml on server as physical file and use it in page i opened in iframe to edit the record. so i am confused... can anybody please guide me that what shpould i do to let user provide interface to edit this xml data/user profile ?

  • Can any postfix guru assist me determine how emails are still being sent via my server from unauthorized sources?

    - by Dave
    Hi all, I'm getting a little concerned as I run a small server hosting a number of websites and manage the email for a few dozen people. Just recently though I've had a couple of notifications from spamcop alerting me that spam has been sent from my server, and when I have a look over the logs from time to time I can indeed see that there are many repeated attempts of mail being sent from my server. Most of the time it gets knocked back from the destination servers but sometimes its getting through. Unfortunately I'm not linux or postfix expert, I can get by but had though I had my machine locked down quite securely, I don't allow relaying, when I check the online DNS/MX tools they tend to report my server as being OK so I'm not sure where to take it now and hoping someone might be able to throw me a few pointers. I get lots of entries like this in my MAIL.INFO log Jan 2 08:39:34 Debian-50-lenny-64-LAMP postfix/qmgr[15993]: 66B88257C12F: from=<>, size=3116, nrcpt=1 (queue active) Jan 2 08:39:34 Debian-50-lenny-64-LAMP postfix/qmgr[15993]: 614C2257C1BC: from=<[email protected]>, size=2490, nrcpt=3 (queue active) and Jan 7 16:09:37 Debian-50-lenny-64-LAMP postfix/error[6471]: 0A316257C204: to=<[email protected]>, relay=none, delay=384387, delays=384384/3/0/0.01, dsn=4.0.0, status=deferred (delivery temporarily suspended: host mx.fakemx.net[46.4.35.23] refused to talk to me: 421 mx.fakemx.net Service Unavailable) Jan 7 16:09:37 Debian-50-lenny-64-LAMP postfix/error[6470]: 5848C257C20D: to=<[email protected]>, relay=none, delay=384373, delays=384370/3/0/0.01, dsn=4.0.0, status=deferred (delivery temporarily suspended: host mx.fakemx.net[46.4.35.23] refused to talk to me: 421 mx.fakemx.net Service Unavailable) then there tends to be connection timeouts, so from what I see even though I had relaying disabled.. something is getting by and trying to send.. So if you can help that will be greatly appreciated, and any further logging/config info I can supply. Thanks

  • Lost Permission on Files using wrong chmod syntax Centos 5.5

    - by alloutfallout
    Hello, I was trying to remove write permissions on an entire directory, and I used the incorrect command: chmod 644 -r sites/default I meant to type chmod -R 644 sites/default The result was this: chmod: cannot access `644': No such file or directory $ ls -als sites total 24 4 drwxr-xr-x 5 user group 4096 Jan 11 10:54 . 4 drwxrwxr-x 14 user group 4096 Jan 11 10:11 .. 4 drwxr-xr-x 4 user group 4096 Jan 5 01:25 all 4 d-w------- 3 user group 4096 Jan 11 10:43 default 4 -rw-r--r-- 1 user group 1849 Apr 15 2010 example.sites.php I fixed the permissions on the default folder with $ chmod 644 sites/default But, the following ls shows a all the files with red backgrounds and question marks. I can't access any files unless I am root. $ ls -als sites/default total 0 ? ?--------- ? ? ? ? ? . ? ?--------- ? ? ? ? ? .. ? ?--------- ? ? ? ? ? default.settings.php ? ?--------- ? ? ? ? ? files ? ?--------- ? ? ? ? ? settings.php When I log in as root, I can edit all of the files, and their permissions appear correctly. I do not know how to undo the damage caused by using -r with chmod instead of -R. Any Suggestions?

  • Apache22 on FreeBSD - Starts, does not respond to requests

    - by NuclearDog
    Hey folks! I'm running Apache 2.2.17 with the peruser MPM on FreeBSD 8.2-RC1 on Amazon's EC2 (so it's XEN). It was installed from ports. My problem is that, although Apache is running, listening for, and accepting connections, it doesn't actually respond to any or show them in the log at all. If I telnet to the port it's listening on and type out an HTTP request: GET / HTTP/1.1 Host: asdfasdf And hit enter a couple of times, it just sits there... Nothing. No response requesting with a browser either. There doesn't appear to be anything helpful in the error log: [Sun Jan 09 16:56:24 2011] [warn] Init: Session Cache is not configured [hint: SSLSessionCache] [Sun Jan 09 16:56:25 2011] [notice] Digest: generating secret for digest authentication ... [Sun Jan 09 16:56:25 2011] [notice] Digest: done [Sun Jan 09 16:56:25 2011] [notice] Apache/2.2.17 (FreeBSD) mod_ssl/2.2.17 The access log stays empty: root:/var/log# wc httpd-access.log 0 0 0 httpd-access.log root:/var/log# I've tried with accf_http and accf_data both enabled and disabled, and with both the stock configuration and my customized config. I also tried uninstalling apache22-peruser-mpm and just installing straight apache22... Still no luck. I tried removing all of the LoadModule lines from httpd.conf and just re-enabled the ones that were necessary to parse the config. Ended up with only the following loaded: root:/usr/local/etc/apache22# /usr/local/sbin/apachectl -M Loaded Modules: core_module (static) mpm_peruser_module (static) http_module (static) so_module (static) authz_host_module (shared) log_config_module (shared) alias_module (shared) Syntax OK root:/usr/local/etc/apache22# Same results. Apache is definitely what's listening on port 80: root:/usr/local/etc/apache22# sockstat -4 | grep httpd root httpd 43789 3 tcp4 6 *:80 *:* root httpd 43789 4 tcp4 *:* *:* root:/usr/local/etc/apache22# And I know it's not a firewall issue as there is nothing running locally, and connecting from the local box to 127.0.0.1:80 results in the same issue. Does anyone have any idea what's going on? Why it would be doing this? I've exhausted all of my debugging expertise. :/ Thanks for any suggestions!

  • Good book for a software developer doing part-time (Linux) system administration work

    - by Tony Meyer
    In many smaller organisations, developers often end up doing some system administration work (for obvious reasons). A lot of the time, they have great developer skills, but few system administration skills (perhaps all self-taught), and so have to learn as they go, which is fairly inefficient. Are there canonical (or simply great) books that would help in this situation? More advanced than just using a shell (presumably a developer can do that), but not aimed at someone that hopes to spend many years doing this work. Ideally, something fairly generic (although specific to a distribution would be OK), covering databases, networking, general maintenance, etc, not just one specific task. For the most part, I'm interested in shell-based work (i.e. no GUI installed), although if there's something outstanding I'm missing, please point it out. (As an analogy, replace "system administration" with C, and I'd want K&R, with C++ and I'd want Meyers' "Effective C++").

  • How to chroot Apache on CentOS?

    - by Jonathan Meyer
    I have been advised by a sysadmin, to run Apache in a chroot jail, in order to prevent that an attacker could take control of server. So my question is: What is the best method to chroot Apache/2.2.3 in RHEL/CentOS 5?, i only use the default modules that comes with Apache like mod_php and also mod_security. I heard of mod_security SecChrootDir but i don't know if it would be suitable for my config, it says that it's recommended only for static file serving in the documentation. Thank you!

  • Excel: conditionally format a cell using the format of another, content-matching cell

    I have an Excel spreadsheet where I’d like to be able to create a “key” of formatted cells with unique values, and then in another sheet format cells using the key formatting. So for example, my key is as follows, with one value per cell and the visual formatting indicated in parentheses: A (red background) B (green background) C (blue background) So that’s on one sheet (or in a remote corner of the current sheet—whichever is better). Then, in an area that I mark for conditional formatting, I can type one of those three letters and have the cell where I typed it visually formatted according to the key. So if I type a “B” into one of the conditionally formatted cells, it gets a green background. (Note that I’m using backgrounds here solely for ease of explanation: ideally I want to have all visual formatting copied over, whether it’s foreground color, background color, font weight, borders, or whatever. But I’ll take what I can get, obviously.) And—just to make it extra-tricky—if I change the formatting in the key, that change should be reflected in cells that reference the key. Thus, if I change the “B” formatting in the key from a green background to a purple background, any “B” in the main sheet should switch to the new color. Similarly, it should be possible to add or remove values from the key and have those changes applied to the main data set. I’m okay with the formatting-update-on-key-change being triggered by clicking a button or something. I suspect that if any of this is possible it will require VBA, but I’ve never used it so I’ve no idea where to start if that’s the case. I’m hoping it’s possible without VBA. I know it’s possible to just use multiple conditional formats, but my use case here is that I’m trying to create the above-described capability for someone who isn’t conversant with conditional formatting. I’d like to let them be able to define a key, update it if necessary, and keep on truckin’ without me having to rewrite the spreadsheet’s formatting rules for them. --- UPDATE --- So I think I was a bit unclear about my original request. Let me try again with an image. The image shows the “key” on the left, where values and styles are defined using keyboard and mouse input. On the right, you see the data that should be formatted to match the key. Thus if I type a “C” into a cell in the Data area, it should be blue-backed. Furthermore, if I change the formatting of “C” in the Key to have a purple background, all the “C” cells should switch from blue to purple. For further craziness, if I add more to the Key (say, “D” with a yellow background) then any “D” cells will be styled to match; if I remove a Key entry, then matching values in the Data area should revert to default styling. So. Is that more clear? Is it possible, in whole or in part? I don’t have to use conditional formatting for this; in fact, at this point I suspect I probably shouldn’t. But I’m open to any approach!

  • Is it possible to disable the retry mechanism in Exim

    - by Tony Meyer
    I have a very simple Exim configuration that's just forwarding all mail to a set of destination addresses. When immediate delivery to an address fails, the message is added to the queue (and then processed by the retry rules). I want to change this so that if immediately delivery fails, the message is :blackhole:d. (It's ok if a bounce is generated instead, as I'll just redirect the bounce to the :blackhole:). This needs to occur for temporary failures (i.e. 4xx) as well as permanent (i.e. 5xx) ones. I understand that this means that if delivery can't be done immediately the message will be permanently and irretrievably lost. In this particular context, that isn't a problem. Reading over this, it sounds suspiciously like "how can I improve my spamming Exim server". That really isn't what this is for, and if you can figure out a way I can prove that, I'm happy to do so!

  • 'Multi' partition recipe from Ubuntu alternate install CD without preseed

    - by Nick Meyer
    The Ubuntu/Debian installer includes a built-in guided partitioning recipe, called 'multi', which creates separate /home, /usr, /var, and /tmp partitions. It can be selected by starting the installer with a preseed file. You can see it described in the Karmic install guide: # You can choose one of the three predefined partitioning recipes: # - atomic: all files in one partition # - home: separate /home partition # - multi: separate /home, /usr, /var, and /tmp partitions d-i partman-auto/choose_recipe select atomic Is there any way to use guided partitioning with this recipe from the Ubuntu alternate install CD without the need to create a preseed file?

  • Find edited Word attachment opened via Windows Mail (Vista)

    - by Tony Meyer
    If you open (not save) a Word attachment in Windows Mail, then it will open the document up in Microsoft Word. This is saved somewhere, and you can edit the file and save it (i.e. no "save as" dialog appears). If you then close Word without explicitly saving the file somewhere, how do you then find the edited file? (Assuming that it can be found, and isn't automatically deleted). Windows Search does not find the file (presumably because it's in the folders that are excluded from search).

  • How to get iTunes to recognize that certain ID3 tags have been removed from files?

    - by Nick Meyer
    I use MusicBrainz Picard to manage the ID3 tags on my MP3 collection and iTunes for playing them and managing my iPod. I have Picard set to remove the Composer tag from any files that don't also contain the word "Classical" in the Genre tag. I've run Picard and it has removed the Composer tag from many of my files. However, iTunes keeps displaying the old value of the Composer field. I have tried right-clicking on the file to update, choosing "Get Info" and clicking OK. This has no effect on the Composer field when it has been removed entirely; it only refreshes the displayed value when it has been changed from one non-empty value to another. How can I get iTunes to stop showing the old values for tags that have been removed? Please note I don't want to lose other iTunes metadata such as ratings and play counts, so removing the files from the iTunes library and re-adding them is not an option.

  • Speeding up Connection Between Computer and Wireless/Bridged Router

    - by Justian Meyer
    Hey everyone, I looked through other questions, but didn't find useful responses. Our main computer has a dl speed of 6 Mbps, but some of our other computers are getting only 40-200 Kb! The router is wireless, but all computers are connected using a Netgear Wall-Plugged Bridge XE102, which transmits information via the building's powerline. It can't be the hardware itself, however, because some computers still manage decent speeds. The computers afflicted are running on Microsoft XP Service Packs 2 and 3, but so are computers that are totally functional. These speeds severely impede on productivity and are excruciatingly frustrating when trying to cram in time in the early hours. Could it be an issue with the computer? Location? Router? Many thanks in advance, Justian

  • Client unable to access OWA website after temporarily changing SSL certificate on the server

    - by Lorenz Meyer
    I have the following issue: One client computer (Windows XP) cannot access the OWA website. All other client computers can (Except another one in the same remote office). How this happened: I temporarily changed the SSL certificate on the Exchange Server yesterday. After a few minutes, I reverted back, an now the same certificate that was installed for years is back again. During these few minutes, they were in OWA on this computer and got a certificate error. What exactly happens: Internet Explorer displays the error Internet Explorer cannot display the webpage, Firefox displays The connection was reset and Crome shows This webpage is not available. The connection to ... was interrupted. What I already did to try to get this working: Restart the client computer Restart the exchange server Deleted Internet Explorer browsing history In IE, Internet Options, tab Content, under Certificates deletes SSL cache Restored Internet Explorer to the default parameters I looked into certmgr.msc, but did not find a certificate related to the issue What could I do else to narrow down the origin of this problem (or better: resolve it) ? Can you give any advice ?

  • Exchange 2010 - Certificate error on internal Outlook 2013 connections

    - by Lorenz Meyer
    I have an Exchange 2010 and Outlook 2003. The exchange server has a wildcard SSL certificate installed *.domain.com, (for use with autodiscover.domain.com and mail.domain.com). The local fqdn of the Exchange server is exch.domain.local. With this configuration there is no problem. Now I started upgrading all Outlook 2003 to Outlook 2013, and I start to get consistently a certificate error in Outlook : The Name on the security certificate is invalid or does not match the name of the site I understand why I get that error: Outlook 2013 is connecting to exch.domain.local while the certificate is for *.domain.com. I was ready to buy a SAN (Subject Alternate Names) Certificate, that contains the three domains exch.domain.local, mail.domain.com, autodiscover.domain.com. But there is a hindrance: the certificate provider (in my case Godaddy) requires that the domain is validated as being our property. Now it is not possible for an internal domain that is not accessible from the internet. So this turns out not to be an option. Create self-signed SAN certificate with an Enterprise CA is an other option that is barely viable: There would be certificate error with every access to webmail, and I had to install the certificate on all Outlook clients. What is a recommended viable solution ? Is it possible to disable certificate checking in Outlook ? Or how could I change the Exchange server configuration so that the public domain name is used for all connections ? Or is there another solution I'm not thinking of ? Any advice is welcome.

  • Fatal error: Out of memory (allocated ...) (tried to allocate ... bytes) not due to memory_limit setting

    - by Lorenz Meyer
    Since a few days, I get the following error on my server: Fatal error: Out of memory (allocated 262144) (tried to allocate 393216 bytes) Usually this error is due to a memory consumption that is exceeding the configured memory_limit, but in my case there is no relation. The memory_limit is set to 128MB, and in this case, we not even reach 1MB. Also the server does not have a big load, in fact it is an intranet server, and there are just a few people conected to it. System: Windows Server 2003, 1Go RAM, only 600 MB used. Apache 2.2.4 PHP 5.2.3 This error is appearing randomly. The memory limit reached also is randomly between a few kB to a few MB. Sometimes restarting Apache is required to get rid of the error, sometimes it disapears itself. Restarting Apache or the entire server helps temporarily. Where could this problem come from ? How could I narrow down the error source ?

  • What’s New in The Second Edition of Regular Expressions Cookbook

    - by Jan Goyvaerts
    %COOKBOOKFRAME% The second edition of Regular Expressions Cookbook is a completely revised edition, not just a minor update. All of the content from the first edition has been updated for the latest versions of the regular expression flavors and programming languages we discuss. We’ve corrected all errors that we could find and rewritten many sections that were either unclear or lacking in detail. And lack of detail was not something the first edition was accused of. Expect the second edition to really dot all i’s and cross all t’s. A few sections were removed. In particular, we removed much talk about browser inconsistencies as modern browsers are much more compatible with the official JavaScript standard. There is plenty of new content. The second edition has 101 more pages, bringing the total to 612. It’s almost 20% bigger than the first edition. We’ve added XRegExp as an additional regex flavor to all recipes throughout the book where XRegExp provides a better solution than standard JavaScript. We did keep the standard JavaScript solutions, so you can decide which is better for your needs. The new edition adds 21 recipes, bringing the total to 146. 14 of the new recipes are in the new Source Code and Log Files chapter. These recipes demonstrate techniques that are very useful for manipulating source code in a text editor and for dealing with log files using a grep tool. Chapter 3 which has recipes for programming with regular expressions gets only one new recipe, but it’s a doozy. If anyone has ever flamed you for using a regular expression instead of a parser, you’ll now be able to tell them how you can create your own parser by mixing regular expressions with procedural code. Combined with the recipes from the new Source Code and Log Files chapter, you can create parsers for whatever custom language or file format you like. If you have any interest in regular expressions at all, whether you’re a beginner or already consider yourself an expert, you definitely need a copy of the second edition of Regular Expressions Cookbook if you didn’t already buy the first. If you did buy the first edition, and you often find yourself referring back to it, then the second edition is a very worthwhile upgrade. You can buy the second edition of Regular Expressions Cookbook from Amazon or wherever technical books are sold. Ask for ISBN 1449319432.

  • Replacement Text Syntax for JavaScript’s String.replace()

    - by Jan Goyvaerts
    A RegexBuddy user told me that he couldn’t easily find a detailed explanation of the replacement text syntax supported by the String.replace() function in JavaScript. I had to admin that my own web page about JavaScript’s regular expression support was also lacking. I’ve now added a new Replacement Syntax section that has all the details. I’ll summarize it here: $1: Text matched by the first capturing group or the literal text $1 if the regex has no capturing groups. $99: Text matched by the 99th capturing group if the regex has 99 or more groups. Text matched by the 9th capturing group followed by a literal 9 if the regex has 9 or more but less than 99 groups. The literal text $99 if the regex has fewer than 9 groups. $+: Text matched by the highest-numbered capturing group. Replaced with nothing if the highest-numbered group didn’t participate in the match. $&: Text matched by the entire regex. You cannot use $0 for this. $` (backtick): Text to the left of the regex match. $' (single quote): Text to the right of the regex match. $_: The entire subject string.

  • What’s New in Delphi XE6 Regular Expressions

    - by Jan Goyvaerts
    There’s not much new in the regular expression support in Delphi XE6. The big change that should be made, upgrading to PCRE 8.30 or later and switching to the pcre16 functions that use UTF-16, still hasn’t been made. XE6 still uses PCRE 7.9 and thus continues to require conversion from the UTF-16 strings that Delphi uses natively to the UTF-8 strings that older versions of PCRE require. Delphi XE6 does fix one important issue that has plagued TRegEx since it was introduced in Delphi XE. Previously, TRegEx could not find zero-length matches. So a regex like (?m)^ that should find a zero-length match at the start of each line would not find any matches at all with TRegEx. The reason for this is that TRegEx uses TPerlRegEx to do the heavy lifting. TPerlRegEx sets its State property to [preNotEmpty] in its constructor, which tells it to skip zero-length matches. This is not a problem with TPerlRegEx because users of this class can change the State property. But TRegEx does not provide a way to change this property. So in Delphi XE5 and prior, TRegEx cannot find zero-length matches. In Delphi XE6 TPerlRegEx’s constructor was changed to initialize State to the empty set. This means TRegEx is now able to find zero-length matches. TRegex.Replace() using the regex (?m)^ now inserts the replacement at the start of each line, as you would expect. If you use TPerlRegEx directly, you’ll need to set State to [preNotEmpty] in your own code if you relied on its behavior to skip zero-length matches. You will need to check existing applications that use TRegEx for regular expressions that incorrectly allow zero-length matches. In XE5 and prior, TRegEx using \d* would match all numbers in a string. In XE6, the same regex still matches all numbers, but also finds a zero-length match at each position in the string. RegexBuddy 4 warns about zero-length matches on the Create panel if you set it to Detailed mode. At the bottom of the regex tree there will be a node saying either “your regular expression may find zero-length matches” or “zero-length matches will be skipped” depending on whether your application allows zero-length matches (XE6 TRegEx) or not (XE–XE5 TRegEx).

  • New regular expression features in PCRE 8.34 and 8.35

    - by Jan Goyvaerts
    PCRE 8.34 adds some new regex features and changes the behavior of a few to make it better compatible with the latest versions of Perl. There are no changes to the regex syntax in PCRE 8.35. \o{377} is now an octal escape just like \377. This syntax was first introduced in Perl 5.12. It avoids any confusion between octal escapes and backreferences. It also allows octal numbers beyond 377 to be used. E.g. \o{400} is the same as \x{100}. If you have any reason to use octal escapes instead of hexadecimal escapes then you should definitely use the new syntax. Because of this change, \o is now an error when it doesn’t form a valid octal escape. Previously \o was a literal o and \o{377} was a sequence of 337 o‘s. In free-spacing mode, whitespace between a quantifier and the ? that makes it lazy or the + that makes it possessive is now ignored. In Perl this has always been the case. In PCRE 8.33 and prior, whitespace ended a quantifier and any following ? or + was seen as a second quantifier and thus an error. The shorthand \s now matches the vertical tab character in addition to the other whitespace characters it previously matched. Perl 5.18 made the same change. Many other regex flavors have always included the vertical tab in \s, just like POSIX has always included it in [[:space:]]. Names of capturing groups are no longer allowed to start with a digit. This has always been the case in Perl since named groups were added to Perl 5.10. PCRE 8.33 and prior even allowed group names to consist entirely of digits. [[:<:]] and [[::]] are now treated as POSIX-style word boundaries. They match at the start and the end of a word. Though they use similar syntax, these have nothing to do with POSIX character classes and cannot be used inside character classes. Perl does not support POSIX word boundaries. The same changes affect PHP 5.5.10 (and later) and R 3.0.3 (and later) as they have been updated to use PCRE 8.34. RegexBuddy and RegexMagic have been updated to support the latest versions of PCRE, PHP, and R. Older versions that were previously supported are still supported, so you can compare or convert your regular expressions between the latest versions of PCRE, PHP, and R and whichever version you were using previously.

  • Regular Expressions Reference Tables Updated

    - by Jan Goyvaerts
    The regular expressions reference on the Regular-Expressions.info website was completely overhauled with the big update of that site last month. In the past, the reference section consisted of two parts. One part was a summary of the regex features commonly found in Perl-style regex flavors with short descriptions and examples. This part of the reference ignored differences between regex flavors and omitted most features that don’t have wide support. The other part was a regular expression flavor comparison that listed many more regex features along with YES/no indicators for many regex flavors, but without any explanations of the features. When reworking the site, I wanted to make the reference section more detailed, with descriptions and examples of all the syntax supported by the flavors discussed on the site. Doing that resulted in a reference that lists many features that are only supported by a few regex flavors. For such a reference to be usable, it needs to indicate which flavors support each feature. My original design for the new reference table used two rows for each feature. The first row had 4 columns with a label, syntax, description, and example, similar to the old reference tables. The second row had 20 columns indicating which versions of which flavors support these features. While the double-row design allowed all the information to fit within the table without requiring horizontal scrolling, it made it more difficult to quickly scan the tables for the feature you’re looking for. To make the new reference tables easier to read, they now have only a single row for each feature. The first 4 columns are the same as before. The remaining two columns show which versions of two regular expression flavors support the feature. You can use the drop-down lists above the table to choose the flavors the table should indicate. The site uses cookies to allow the flavor choices to persist while you navigate the reference. The result of this latest update is that the new regex tables are now just as easy to read as the ten-year-old tables on the old site were, while still covering all the features big and small of all the flavors discussed on the site.

  • #1 O’Reilly eBook for 2010

    - by Jan Goyvaerts
    The year-end issue of O’Reilly’s author newsletter discussed the trends O’Reilly has been seeing the past few years, and their predictions for 2011. The key trend is that digital is now more than ever poised to take over print: Our digitally distributed products have grown from 18.36% of our publishing mix in 2009 to 28.09% of our mix in 2010. What is more impressive is that our digitally distributed products have produced more than double the revenue that has been lost with the decline of print. I think this is important because some say that digital cannibalizes print products. Our data indicates the contrary, as print is declining much more slowly than digital is growing. I think we may be seeing developers purchasing a print book, and then purchasing the electronic editions to search and copying code from, as the incremental cost for digital is more than reasonable. My own book seems to be leading this trend. Thanks to everyone who purchased it! And the five bestselling O’Reilly ebook products for 2010: 1) Regular Expressions Cookbook, 2) jQuery Cookbook, 3) Learning Python, 4) HTML5: Up and Running, and 5) JavaScript Cookbook. I think it’s interesting that the top five ebooks are code-intensive books. They’re great products for search and code reuse. It’s also interesting that none of the top 5 ebooks made the top 5 of print books.
