• How can I print legible text in a font size <1.5?

  - by user330372

  For biological research, I need to print characters so tiny that 2 of them fit in less than 0.5 mm, which I will read under a microscope. I am currently printing from Excel at font size of 1.5, using a HP LaserJet 400M. The result is slightly larger than what I need it to be, but printing at size 1 produces unreadable results. How can I print a smaller font size but still get readable results? Are there specialized printers for that? Where could I find one?

• Writing functions of tuples conveniently in Scala

  - by Alexey Romanov

  Quite a few functions on Map take a function on a key-value tuple as the argument. E.g. def foreach(f: ((A, B)) ? Unit): Unit. So I looked for a short way to write an argument to foreach: > val map = Map(1 -> 2, 3 -> 4) map: scala.collection.immutable.Map[Int,Int] = Map(1 -> 2, 3 -> 4) > map.foreach((k, v) => println(k)) error: wrong number of parameters; expected = 1 map.foreach((k, v) => println(k)) ^ > map.foreach({(k, v) => println(k)}) error: wrong number of parameters; expected = 1 map.foreach({(k, v) => println(k)}) ^ > map.foreach(case (k, v) => println(k)) error: illegal start of simple expression map.foreach(case (k, v) => println(k)) ^ I can do > map.foreach(_ match {case (k, v) => println(k)}) 1 3 Any better alternatives?

• is it okay to use random URLs instead of passwords?

  - by stew

  Is it considered "safe" to use URL constructed from random characters like this? http://example.com/EU3uc654/Photos I'd like to put some files/picture galleries on a webserver that are only to be accessed by a small group of users. My main concern is that the files should not get picked up by search-engines or curious power-users that poke around my site. I've set up an .htaccess file, just to notice that clicking on http://user:pass@url/ links doesn't work well with some browsers/email clients, prompting dialogs and warnings messages that confuse my not-too-computer-savy users.

• Copy files with original folder structure, but to 8.3 format

  - by kokbira

  I have a folder with a lot of files and folders inside it. I would like to copy that to another location so the result is a folder with the same file and folder structure, but with all files in 8.3 format. How to do it? PS: Well, some files have extensions with more than 3 characters (e.x. home.sh3d, windows.theme etc.), so when I say about transforming all filenames to 8.3 I would like to say about transforming them to a 8.X format (i.e., to do not change extensions).

• Bad password when logging in via Remote Desktop

  - by Shiraz Bhaiji

  I have just setup a windows 2003 server running in hyper-V. When I log in via Hyper-V it works fine. When I try to login via remote desktop I get a bad user name or password error. I have: Disabled the firewall Enabled remote connections Before I did the above I did not get to the login screen. I can ping the ip address of the image. I am trying to login as Administrator. Anyone have an idea about how to fix this? Edit I have now managed to fix this by changing the password to something without special characters. Strange thing is the I could not see any problems with the passord, had tried typing it into the user name field to check it.

• C# array of objects - conditional validation

  - by fishdump

  Sorry about the vague title! I have an class with a number of member variables (system, zone, site, ...) public sealed class Cello { public String Company; public String Zone; public String System; public String Site; public String Facility; public String Process; //... } I have an array of objects of this class. private Cello[] m_cellos = null; // ... I need to know whether the array contains objects with the same site but different systems, zones or companies since such a situation would be illegal. I have various other checks to make but they are all along similar lines. The Array class has a number of functions that look promising but I am not very up on defining 'key selector' functions and things like that. Any suggestions or pointers would be greatly appreciated. --- Alistair.

• Python + Expat: Error on &#0; entities

  - by clacke

  I have written a small function, which uses ElementTree and xpath to extract the text contents of certain elements in an xml file: #!/usr/bin/env python2.5 import doctest from xml.etree import ElementTree from StringIO import StringIO def parse_xml_etree(sin, xpath): """ Takes as input a stream containing XML and an XPath expression. Applies the XPath expression to the XML and returns a generator yielding the text contents of each element returned. >>> parse_xml_etree( ... StringIO('<test><elem1>one</elem1><elem2>two</elem2></test>'), ... '//elem1').next() 'one' >>> parse_xml_etree( ... StringIO('<test><elem1>one</elem1><elem2>two</elem2></test>'), ... '//elem2').next() 'two' >>> parse_xml_etree( ... StringIO('<test><null>&#0;</null><elem3>three</elem3></test>'), ... '//elem2').next() 'three' """ tree = ElementTree.parse(sin) for element in tree.findall(xpath): yield element.text if __name__ == '__main__': doctest.testmod(verbose=True) The third test fails with the following exception: ExpatError: reference to invalid character number: line 1, column 13 Is the � entity illegal XML? Regardless whether it is or not, the files I want to parse contain it, and I need some way to parse them. Any suggestions for another parser than Expat, or settings for Expat, that would allow me to do that?

• Drupal 6 Validation for Form Callback Function

  - by Wade

  I have a simple form with a select menu on the node display page. Is there an easy way to validate the form in my callback function? By validation I don't mean anything advanced, just to check that the values actually existed in the form array. For example, without ajax, if my select menu has 3 items and I add a 4th item and try to submit the form, drupal will give an error saying something similar to "an illegal choice was made, please contact the admin." With ajax this 4th item you created would get saved into the database. So do I have to write validation like if ($select_item > 0 && $select_item <= 3) { //insert into db } Or is there an easier way that will check that the item actually existed in the form array? I'm hoping there is since without ajax, drupal will not submit the form if it was manipulated. Thanks. EDIT: So I basically need this in my callback function? $form_state = array('storage' => NULL, 'submitted' => FALSE); $form_build_id = $_POST['form_build_id']; $form = form_get_cache($form_build_id, $form_state); $args = $form['#parameters']; $form_id = array_shift($args); $form_state['post'] = $form['#post'] = $_POST; $form['#programmed'] = $form['#redirect'] = FALSE; drupal_process_form($form_id, $form, $form_state); To get $_POST['form_build_id'], I sent it as a data param, is that right? Where I use form_get_cache, looks like there is no data. Kind of lost now.

• Reverse engineering and redistributing code from .NET Framework

  - by ToxicAvenger

  Once or twice I have been running into the following issue: Classes I want to reuse in my applications (and possibly redistribute) exist in the .NET Framework assemblies, but are marked internal or private. So it is impossible to reuse them directly. One way is to disassemble them, pick the pieces you need, put them in a different namespace, recompile (this can be some effort, but usually works quite well). My question is: Is this legal? Is this only legal for the classes of the Framework which are available as source code anyway? Is it illegal? I think that Microsoft marks them internal or private primarily so that they don't have to support them or can change the interfaces later. But some pieces - be it SharePoint or WCF - are almost impossible to properly extend by only using public classes from the apis. And rewriting everything from scratch generates a huge amount of effort, before you even start solving the problem you intended to solve. This is in my eyes not a "dirty" approach per se. The classes Microsoft ships are obviously well tested, if I reuse them under a different namespace I have "control" over them. If Microsoft changes the original implementation, my code won't be affected (some internals in WCF changed quite a bit with v4). It is not a super-clean approach. I would much prefer Microsoft making several classes public, because there are some nice classes hidden inside the framework.

• git log throws error "ambiguous argument"

  - by LonelyPixel

  This used to work about a year ago. Now it doesn't: git log --abbrev=6 The expected result would be all commit hashes abbreviated to 6 characters. The actual result is now this error message: fatal: ambiguous argument '6': unknown revision or path not in the working tree. Use '--' to separate paths from revisions, like this: 'git [...] -- [...]' I have the impression that Git doesn't even know about that argument and tries to silently ignore its name but not the value. Using Git 1.8.1.msysgit.1 on Windows 7. Addition: Oh and it fails on other parameters, too. The entire command is: git log --abbrev=6 --format=format:"----- Commit %%h on %%ci by %%an -----%%n%%n%%B" If I just leave the abbrev part out, it still returns another error: fatal: Invalid object name 'format'.

• All items in my pen drive had been renamed automatically and cannot open it

  - by pabz

  All the items (both files and folders) inside my pen drive had been renamed to some characters like :]h.¡?.A++ and when I try to open any folder Windows gives this message. The filename,directory name, or volume label syntax is incorrect I was told that it is a problem of the pen drive, not a virus. They say if I format the pendrive then I will be able to use it again normally. But I'm not sure. And I need those files. Does anybody knows a solution?

• SSRS report font problem on deployed reports

  - by Cylindric

  I have created several reports for my SQL Server Reporting Services 2008 SP2 server, using Visual Studio 2008 on my machine. The reports objects all use Arial as their font, in various sizes and weights. When I test them in VS, all looks fine, and I can print them and export them okay. When I deploy them to the server though, they look fine on-screen and if exported to PDF, but when printed directly from the web viewer, the fonts seem to go 'missing' - all the characters are squashed together as if there was a slight negative character-offset.

• wireless printer - entering WPA - is there a quicker way?

  - by camcam

  I have a wireless printer (Brother DCP-585CW). The wireless setup instruction says I should enter the WPA key to the printer. The key is entered using up and down buttons on the printer. So, I am supposed to enter 64 characters using up and down buttons. To enter 1 character, it takes on average (24+10)/2 = 17 times pressing the button (digits start after 24 letters). So 17*64 = 1088 times. Is there a quicker way to setup a wireless printer? Maybe there is a Windows program that discovers printers connected to computer through USB or Ethernet (my printer has both sockets) and allows to pre-configure it for wireless usage (enter the long WPA key)? Update There is BRAdmin program and it allows to set up almost all wireless settings... almost - all except WPA :(

• how to get a decent emacs setup on linux

  - by Hersheezy

  I am currently interested in switching from vim to emacs. One of the more compelling reasons for this is the smooth integration with a unix environment. The most experienced emacs users I have seen have a bash prompt at the bottom of their window, with stdout going to a buffer right above it. They then interact with the output of programs such as grep in interesting ways. I am on Ubuntu 10.04 and the default emacs environment does not seem to do much for me in the way of integration. For example, in the M-x shell mode, output from basic commands like ls produce lots of strange characters and hitting the up arrow does not go to previous commands. Any recommendations on a good direction to go in?

• Shell script to fix bad filenames? [closed]

  - by Ze'ev

  I'm IT at my small firm; and, despite my dire warnings, everyone puts files on the server with awful names, including leading & trailing spaces, bad characters (including \ ; / + . < > - etc!) They do this by accessing the (FreeBSD/FreeNAS) server via AFP on Macs, so no part of the system complains. Is there a script I can use to go through an entire directory tree and fix bad filenames? Basically replace all spaces & bad ASCII with _ ... and if a file already exists, just slap a _2 or something on the end. I don't suppose there's a way to get the system to enforce good filenaming conventions, is there?

• Is there a limit of max. number of files in external hard drive folder?

  - by tfs

  I have a FAT32 external hard drive where I keep backups downloaded from webserver. I have a directory with 30 subdirectories. One of the subdirectories contains 21381 files and when I try to copy more files into this directory I get 0x80070052 error. However,it's possible to copy one more file in this directory (only one) if I make it's name shorter (8 characters instead of 22 as it's original name). How do I solve this problem? Now I can not synchronize external hard disk files with server files which is very important for me.

• Cannot disable index during PL/SQL procedure

  - by nw

  I've written a PL/SQL procedure that would benefit if indexes were first disabled, then rebuilt upon completion. An existing thread suggests this approach: alter session set skip_unusable_indexes = true; alter index your_index unusable; [do import] alter index your_index rebuild; However, I get the following error on the first alter index statement: SQL Error: ORA-14048: a partition maintenance operation may not be combined with other operations ORA-06512: [...] 14048. 00000 - "a partition maintenance operation may not be combined with other operations" *Cause: ALTER TABLE or ALTER INDEX statement attempted to combine a partition maintenance operation (e.g. MOVE PARTITION) with some other operation (e.g. ADD PARTITION or PCTFREE which is illegal *Action: Ensure that a partition maintenance operation is the sole operation specified in ALTER TABLE or ALTER INDEX statement; operations other than those dealing with partitions, default attributes of partitioned tables/indices or specifying that a table be renamed (ALTER TABLE RENAME) may be combined at will The problem index is defined so: CREATE INDEX A11_IX1 ON STREETS ("SHAPE") INDEXTYPE IS "SDE"."ST_SPATIAL_INDEX" PARAMETERS ('ST_GRIDS=890,8010,72090 ST_SRID=2'); This is a custom index type from a 3rd-party vendor, and it causes chronic performance degradation during high-volume update/insert/delete operations. Any suggestions on how to work around this error? By the way, this error only occurs within a PL/SQL block.

• Create my own custom ellipsis bullet point

  - by Airn5475

  I regularly use an ellipsis as a bullet point in a list of items in Word/Outlook 2010. Example: I like summer because... ... it's warm out. ... we go on vacation. ... my birthday is in July. Currently in Word/Outlook if you type certain characters like a hyphen and hit space, it will automatically start a bulleted list using the hyphen. I would really like the same functionality with the ellipsis. When I type the third period and hit space, start a bulleted list. Does anyone know of a way to do this? Registry hack? Hidden Word Setting?

• Blurred refurbished TFT

  - by PeterMmm

  I got 3 refurbished PC+TFT 19". All TFT shows a very blurry image. I estimate the TFT's are 2-3 yrs old. The PC's running Windows7 Pro. The resolution is set to the TFT native values. It could be possible that all TFT's are broken but I have similiar models that are up to 5 yrs old, without any issue. I still think it could be a config issue but from the hardware it is possible that a TFT get broken I shows up a very blurry image. Update TFT HP 2035, grafic Intel Q35/GMA 3100, analog D-SUB connector, Manuf. date Sep 2005. Config. resolution 1600x1200, PPP 150% Without ClearType it is worst. Desktop Icon titles seems to be good and clear. But in Notepad for example the effect is that on the right of the characters is a pinky shadow.

• How to clear current line of command prompt?

  - by JellicleCat

  How can I clear the current line in the command prompt? (I'm using Windows 7.) Too often, I enter a command, execute it, get many lines of output, then wish to enter another command. But before entering the second command, I press the up arrow key to review the first command, then I find I have to hold backspace for 30-or so characters. (I can't just press down again to get an empty line. Nor can I get it by pressing up again.)

• Setting Boot and Mirror Disks correctly at the Solaris OBP

Could someone please explain how to construct this disk path correctly?

• How to use cursor keys to switch buffers in GNU screen

  - by suvayu

  I want to use cursor keys or cursor keys with a modifier like Ctrl to switch between screen buffers (e.g. C-a [arrow] or C-a C-[arrow]). So far I have tried settings like the ones below with no success. bind \224\115 prev bind \224\116 next bindkey -d ^[[1;5D prev bindkey -d ^[[1;5C next They are either ignored or behave unexpectedly (the second one). I am also not sure how to specify the keys. To get the characters, I either used C-v to quote them in bash, or tried to look-up on the Internet (e.g. http://ascii-table.com/ansi-escape-sequences.php). Any idea how I can achieve this key binding?
