"S100apache" won't work, though -- they're sorted alphabetically, not numerically. Stick to two digits. \_ ideally the rc script order numbers are set by a comment line in the /etc/init.d version of hte file.

Ever tried browsing on an iPhone and then on a 30" monitor? Pain in the ass. \_ I like the content to look the same no matter which browser is used. I find things like variable width fonts and autoscaling annoying, because they sometimes don't render correctly. \_ Ah yes, HTML is stupid, everyone should have embraced eternal constant pixel formats such as PDF.

But they'd like to save money by moving this in-house. They're starting with PDF files and want to display them as images in the browser. That part is easy (convert them server- side). But they also want highlighted search results on the images, a la google books. I turn to the mighty motd for advice on how to do this. use a pdf manipulation library to highlight search terms and then convert to jpg? convert pdf to svg and highlight in svg before converting to jpg? drop the job cuz its too hard? sorry for the long post. thx. \_ I suspect drawing a rectangle or something would be the easy way to do it, but that doesn't solve the problem of finding the location of the text in the pdf... \_ I suspect drawing a rectangle or something would be the easy way to do it, but that doesn't solve the problem of finding the location of the text in the pdf... \_ How are you rendering these? HTML --> PDF or using some sort of reporting service (Crystal/SSRS)? If the former, I'd just set up a regular expression and drop in a custom CSS tag before and after the desired text that deserns what needs to be highlighted. Then render the HTML to PDF. \_ well the starting point is InDesign. They export PDFs and send that to their print shop. is there some library out there to manipulate PDFs so that I could just like "highlight search terms" in the document? \_ InDesign has a development forum. I found this there: http://blogs.adobe.com/acrolaw/2007/12/highlighting_multiple_words_in_a.html \_ Probably not, if you mean have it automatically highlight the text for you. \_ http://www.devdirect.com/all/PDF_MAnipulation_PCAT_2070.aspx  2009/1/20-26 [Computer/SW/Languages/Java, Computer/SW/Languages/Misc] UID:52425 Activity:nil 1/20 I've been using tcsh as shell program tool (i know, bad shell to do scripting). One thing I've noticed when I extract xml file is that the variable type automatically change from integer/string to... almost an array-like data structure when the output of the xml key/value is more than one (it's more like a string separated by space, but I was very impressed as it is). 1. since *WHEN* did this happened? or shell variable always behave this way? 2. I've notice that the first element of this "array" started with index of [1] instead of [0]. This is rather different from c/java type of syntax. is [0] reserved for something? or it's just a different convention? \_ I don't understand question 1. Tcsh is not strongly typed. It does have integers and strings, but that's about it. Are you talking about$FOO = "this is my string" versus $FOO = (this is my string)? For question 2, the convention is different, yes.  2009/1/14-22 [Computer/SW/Languages/Perl, Computer/SW/Languages/Misc] UID:52378 Activity:nil 1/13 I want to extract a couple integer from an xml file, mainly, xml file from http://weather.com so I can put it on my xplanet marker file. has anyone done similar things (parse and extract data from xml) using shell script instead of python/perl? in the world of perl, it make sense to dump things into a hash which i can easily extract key/value pair. can i achieve similar things with xmllint/xmlcatalog? thanks \_ xmlstarlet lets you do xpath/xslt stuff via the command line \_ didn't know this existed...

Identical httpd.conf files (except for ServerName). But on one, if a CGI script takes longer than 300 seconds, it times out. The other, not. Why is that? \_ Perhaps network equipment configuration. Or try comparing settings in /proc/sys/net. \_ I ran /sbin/sysctl -a | grep tcp, all settings are the same. The only difference I've found so far is that one httpd binary is 32 bit, the other 64 bit. \_ That's a huge difference. Why is that? Your systems aren't even close to similar. Start with that thesis instead of the "identical" thesis. Is one of them a Pentium Pro and the other one a quad core P4, too? \_ They are two separate systems. But the question still is why does one time out, while the other one does not. \_ Could be lots of reasons. What are the differences? Why is one running a 64bit binary, for instance? As it stands your systems don't seem similarly configured or spec'd at all so it's not surprising they behave differently. So what are the differences? Answer that and you have your answer. Also switch network ports (A<->B) and IPs to eliminate that from the equation.  2008/10/8-9 [Computer/SW/Languages/Misc, Computer/SW/Languages/C_Cplusplus] UID:51433 Activity:nil 10/8 Fossil shows how turtles evolved their shells: http://preview.tinyurl.com/4dqlhk [new scientist]  2008/9/7-12 [Computer/SW/Languages/C_Cplusplus, Computer/SW/Languages/Java, Computer/SW/Languages/Misc] UID:51093 Activity:nil 9/7 I want to learn Design Patterns without having to buy the famous book.

The class needs a few path variables defined so that it runs on the correct files. I may want to use different files, so I certainly don't want to hard code them. There are also enough files that I don't want to pass them in as arguments. I thought I might be able to have a file that defines them and import it. so, file test_config.py defines "foo_path = 'blah'" >>> import test_config as foo_config >>> print foo_config.foo_path blah >>> foo_run() in the script file I have: print foo_config.foo_path I get: 'NameError: global name 'foo_config' is not defined' Why does my script file not get the 'global name' foo_config? \_ Is foo_run in a different module? Did you do something like 'import foo_run from foo_run_module'? I'm guessing it would work if you imported foo_config from within foo_run_module. \_ Yes, that works, but I would prefer to be able to interactively load different modules as foo_config. load

How reliable is it? No corruption? Is Disk to Disk copy still buggy? \_ XML? XML!?! Oh dear god, WHY.... \_ Exactly what I thought before I tried it. The raw data is in a bin file, the xml file describtes the content of the bin file in detail, such as disk info, boot sector, file list, etc. This makes it possible to recover the data without having access to the source program. A nice use of XML. \_ Nobody mentioned Acronis TrueImage? It's pretty good and not expensive. I just pirate these things of course.

If your file is actually named with a Chinese character, it's more complicated. With a modern server and browser, you can just put a Chinese character right into the URL. If you have a modern server but you want to support old or non-Chinese browsers, convert the characters to UTF-8, break them into bytes, and percent-encode each byte -- for your example, that would become http://www.whatever.com/%E7%A5%A2.mp3 If you have an old server, do the same thing, but instead of UTF-8, use whatever encoding the server uses for filenames (probably Big5 or GB). --mconst \_ Yes, that's what I am looking for. \_ Yes, that's what I am looking for.

It's not Playfair; having 26 letters argues against any sort of 3-letter code. \_ You couldn't use a Kasiski crack on it because it's too short, but that's why I was trying to look for clues in the job posting itself to supply the key. They wouldn't just post a cipher without some bearing on the posting, subject, company, job, what have you. And the TLAs are a good idea, I tried various ones. Other possibilities are a straightforward jumble. -John \_ dunno if it's related, but the html has this at the top: [my wrapping, they have it on one long line] \_ Only problem: The original string is purely numbers, while this one is alphanumerical.

I don't know what I'd do without you guys. Google and http://php.net are clearly _insuperior_ than the motd. Anyways I have just a few more question. What's the proper way to embed text and binaries into XML? Should I simply call htmlspecialchars() on each item or just HEX it? Second question is, if I let users do "SELECT *" and want to return as XML how do I check the mySQL type for each field(column) name? I tried using mysql_field_type(...) but when it sees a TEXT field, it returns it as a BLOB, wtf? \_ "insuperior than"? \_ Putting binary data in XML sucks. You'll have to basically &#NNN; every out-of-charset byte. Probably best to just base64_encode() it and throw that into the entity. TEXT columns are BLOB columns, they just are searched differently, essentially (case insensitive, respect charset, yadda). I don't know the PHP way to do introspection on your table, offhand, but you could always parse the result of DESC table or SHOW CREATE TABLE table. --dbushong  2006/6/16-19 [Computer/SW/Languages/Perl, Computer/SW/Languages/Misc] UID:43422 Activity:nil 6/16 Is there anyway in Ant to change/append the value in java.library.path before starting the script?

Repeated$x->get_element_by_tagname('aa')->get_element_by_tagname->('bb') ->... doesn't seem to work --dbushong \_ note that it's get_element*s*_by_tagname. it returns an array. note the $h =$hs[0] above. PHP sucks and you can't do $obj->method()[0]->method()[0], etc. so you have to keep assigning to variables. I actually made a function at one point to make this a little easier: function first($arr) { return $arr[0]; } so then you can say:$h = first(\$x->get_elements_by_tagname('hello')); If you want to access a specific deep thing, consider using the xpath functions that API provides. --dbushong

Then I realized that I forgot to change the date on the camera which was set to some date in 2005. I changed the .AVI files to the current dates but picassa still sorts them according to the 2005 date. It must be reading dates embedded in the AVI file itself. I know that JPEGs hav EXIF header which I can change. What do I use to change the embedded dates inside an AVI file? I believe it's mpeg-4 inside. Any FREE tools I can use to do this?

If one asshole decides to do a DoS (fork script) as nobody, there's no way to track down the perpetrator. This is why "suexec" is highly recommended, plus users don't need to chmod a+rx script.cgi. \_ Uh, it's totally trivial to track down the perpetrator with or without suexec. httpd should run as something other than nobody, but that's only because nobody is over-used, and whether httpd runs as nobody is orthogonal to the question of whether suexec should be on. -tom \_ Ok fine.

Has the setup changed in some way, are others also still having problems? Thanks \_ CGI scripts don't seem to be working for me either. --jameslin \_ They were enabled, but due to a misconfiguration, i.e. choice of user/group for CSUA home page, someone used a random hoser's badly written cgi to deface the CSUA web page. Thus, they were disabled. -dans \_ ouch! thanks for the info. So is CGI not going to be available any more, then? Should we be using PHP or something else instead? \_ I'm not on soda root, I'm just filling in folks on current history. As tom indicates, PHP suffers from similar problems. My understanding is that they are working on it, but, being students, have lots of other obligations that supercede making improvements to our little playground. -dans \_ The solution to that is to do a find and fix files owned by nobody/www, not disable CGI. You can do the same thing w/ PHP! \_ Yes, and now the web server is running as "nobody", which I think is not ideal practice ("nobody" is used by too many things; the web server user should be unique to the web server), but should remove the concern about CGIs (which are no more problematic than PHP). -tom \_ Ed claims he just enabled CGI's. -dans \_ Okay, now I'm getting "Premature end of script headers" errors, but these scripts worked fine on the old FreeBSD iteration of soda. I'm basically just doing: #!/bin/sh echo "Content-type: text/html" echo "" echo "

blah

" Also, are the permissions on the apache logs going to be changed? It's sometimes useful to be able to read the error log to figure out what's failing. \_ It's really hard to say without seeing your script. Maybe your path to echo is not set properly? I'm not root, and as far as I know, root doesn't read the motd (at least not as a source of the more things to do). Why don't you try mailing root? -dans \_ Perl cgi is working fine. Most likely, path is not set properly. \_ No, it's not a path problem. The problem went away when I made the script world-readable instead of just world-executable. Why should that matter? \_ because the web server can't read the script if it's not readable. duh. -tom \_ You're begging the question. Why does the web server need to read it? It doesn't need to read it to execute it, and it did it fine in the previous incarnation of soda, so I'm still curious what the rationale is. Does the web server do some analysis of the script beforehand to see if it does unsafe things? \_ It's a *script*. You need to be able to read a script to execute it; how else will the web server see #!/bin/sh? -tom \_ not only that, scripts are INTERPRETED. You can't read shit out of them unless they're read. \_ Yes, that makes total sense. I'm an idiot. I guess I was misled by it working before, but I suppose that's because soda used to use suexec? \_ yes, probably suexec was su'ing to the user before it tried to read the script, therefore it was using the user permissions instead of the world permissions. -tom

I plan to push some of my code back to prototype.js. prototype.js' map function is a crippled map that only takes a one argument function and one list. iGMonkey's map is a true generalized map that takes an n argument function and n lists. Don't get me wrong, I like prototype.js. Also, prototype.js' goal seems to be to make javascript work like ruby, which is fine, if that's what you want. Furthermore, prototype.js is monolithic, as far as I know, there's no way to pick and choose just the bits of functionality you want from it. I am working on a real #include function for javascript to make iGMonkey more component based. Hopefully the prototype.js folks will find this useful. -dans \_ That's it? That's your "I'm going to change the world" project? \_ I don't believe I said I was working on a world changing project. That said, most change is a gradual thing. Sure, if you're the leader of a major world power you can demolish a country on the other side of the world for shits and giggles (oh and because its leader was a bad man), and do it in days. Notably, the real change, i.e. the reconstruction effort usually takes longer.

But here we are 13 \_ You've already been written off as a kook. years later, and Linux has changed the world. To me, starting small is the only sensible way to single-handedly launch a project.

Gang-of-Four or not. \_ Template method: . \_ Houndstooth: . \_ Is that structural or creational? \_ POLKA DOT: . \_ I've never seen a really good reason to use design patterns other than the fact that some of their concepts are built into the language (i.e. Java Swing, etc.). I suppose it makes sense on a language level (better designed, more OO languages, etc.), but I've never seen a very well designed piece of code using the concepts as described by the GOF. In fact, I've seen over designed projects, especially when someone decides to drag in Rational Rose and they go UML crazy. I suppose it works on Really Large Projects (TM), but it certainly holds no place in mid or low level projects, at least not in my experience. I think there's a major disconnect with academia's concept of software engineering and what really goes on in the nitty gritty real world (big surprise).
