• Save and restore multiple layers within a Photoshop action that flattens

  - by SuitCase

  I'm editing comic pages with layers - "background", "foreground", "lineart" and "over lineart". I have a Photoshop action that includes a Mode-Bitmap command, which requires the image to be flattened. I need this part of the action because I use the Halftone Screen method of reducing the greyscale image to bitmap on the "background" layer, creating a certain effect. I am pretty sure there is no filter or anything else that gives the same effect. After the mode is changed to bitmap, my action changes things back to greyscale for further changes. This poses a problem. I only want to do the bitmap mode change on the background layer, and after I do the change I want to restore the layer structure as it was - with the foreground, lineart and over lineart layers back above the now-halftoned background. My current method of saving these layers and restoring them is clumsy. My action is able to automatically save the "foreground" layer by selecting it, cutting it, then pasting it back in after the mode changing is over. But, for the "ink" and "over ink" layers, I have to manually cut these layers, paste them into a new document, and later re-cut and re-paste after running my action. This is so clunky! What I would like to know is if it's possible to set aside my layers in an automated way, and then bring them back in, also in an automated way. An ugly (but functional) solution would be to replicate my actions of creating new documents and pasting them temporarily there, but I don't think Photoshop allows you to do things outside of your current document with an action. It seems to me that the only way to do what I want is to use the "hack" of incorporating the clipboard into the action as a clever hack, but that leaves me stuck as I have two more layers that can't fit onto that same clipboard. Help or suggestions would be appreciated. I can keep on doing it manually, but to have a comprehensive action would save me a ton of time.

• Push, parse & import "selected" data, text, info blobs from Webpages/ Emails as Event/ Appointment to standard Calendar directly or as .ics file?

  - by Alex S

  Any tool, plugin, extension, script/ code to push "selected" data, text, information blobs from Web pages, Emails etc, then parsed and imported to structured Event, Appointment (e.g. .ics) on a standard Calendar like Outlook, Google, iCal? If not, what and how could I use some scripting, coding or existing tools, extensions to add on top and do this. I come across a lot of unstructured information on Webpages, Emails, FB events etc. where I just want to add that information to my Calendar. Instead of entering all the information by hand all the time, there should be an easy enough way to have the information get parsed, organized and imported to a Calendar... Either directly to a calendar from source or Translated to a standard format such as .ICS that can be imported & saved easily. Would love to see some suggestions for this incorporating one or more of the following: on Windows with Chrome & Outlook on iPhone/ iPad to its Calendar PS: I'll come back and see if I can add more information to this question and to answer it as well. I have not found a solution yet.

• Website hosted on my virtualbox web server not displaying images or applying css when viewed through phone

  - by WebweaverD

  I would really appreciate it if someone could help me. Please let me know if you need more info in the comments. My Set Up I have a windows 7 pc. On it I run a virtual box VM with a ubuntu 12 guest os and LAMP setup. I share files between the two machines using samba from linux to windows and using windows file sharing (Workgroup) the other way round. The vm is set up with a bridged network adapter and can happily serve web pages to my host machine. I use DHCP reservations on my home wireless router/modem to reserve an ip for the vm and give it a sitename.dev in my windows host file so I can access it at sitename.dev through the browser. The Problem So far so good but I have a dev project which needs a lot of mobile template development, now obviously I can use a browser plugin to simulate a mobile device but I would like to be able to see the real thing easily on my phone during development. So ideally I would like a similar setup on my iphone to my windows setup Now I'm not great on networking and dont have much experience with web server set up. So when I typed the ip of my virtual box into my iphone i wasnt expecting to see anything. I was pleasantly surprised when my site loaded up. The javascript even seems to be running but the images and css are not happening. My Question 1) What is happening here, is it something to do with the bridged set up on the vm network? 2)How do I make the sites load properly through my phone Notes I've also tried another phone. The same sites viewed on live servers work fine.

• Serve web application error messages from Http server

  - by licorna

  I have nginx as a http server with tomcat as a backend (using proxy_pass). It works great but I want to define my own error pages (404, 500, etc.) and that they are served by nginx and not tomcat. For example I have the following resource: https://domain.com/resource which doesn't exist. If I [GET] that URL then I get a Not Found message from Tomcat and not from nginx. What I want is that every time Tomcat responds with a 404 (or any other error message) nginx sends itself a message to the user: some html file accessible by nginx. The way I have my nginx server configured is very easy, just: location / { proxy_pass http://localhost:8080/<webapp-name>/; } And I've configured port 8080, which is tomcat, as not accessible from outside this machine. I don't think that using different location directives in nginx configuration will work, because there are some resources that depend on the URL: https://domain.com/customer/<non-existent-customer-name>/[GET] Will always return 404 (or any other error message), while: https://domain.com/customer/<existent-customer>/[GET] Will return anything different from 404 (the customer exists). Is there any way of serving Tomcat (Application Server) error messages with Nginx (http Server)? To check the message sent by the proxy_pass directive and act upon it?

• Nginx redirect all request that does not match a file to a php file

  - by cyrbil

  I'm trying to get all request to: http://mydomain.com/downloads/* redirect to http://mydomain.com/downloads/index.php except if the requested file exist in /downloads/ ex: http://mydomain.com/downloads = /downloads/index.php http://mydomain.com/downloads/unknowfile = /downloads/index.php http://mydomain.com/downloads/existingfile = /downloads/existingfile My current problem is I have either the redirection to php working but static files not served or the opposite. Here is my current vhost conf: (which redirect fine but static files are send to php and fail) server { listen 80; ## listen for ipv4; this line is default and implied server_name domain.com; root /data/www; index index.php index.html; location / { try_files $uri $uri/ /index.html; } error_page 404 /404.html; # redirect server error pages to the static page /50x.html error_page 500 502 503 504 /50x.html; location = /50x.html { root /usr/share/nginx/www; } location ^~ /downloads { fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_index index.php; include fastcgi_params; try_files $uri @downloads; } location @downloads { rewrite ^ /downloads/index.php; } # pass the PHP scripts to FastCGI server # location ~ \.php$ { try_files $uri =404; fastcgi_split_path_info ^(.+\.php)(/.+)$; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; include fastcgi_params; } } Precision: static files are symlinks created by /downloads/index.php Thank you for your help.

• Wordpress on Apache is redirecting all https to http

  - by Krist van Besien

  I have a problem with a wordpress site on a server I admin. I don't know anything about wordpress however. My problem is that we want the site to be accessed over https, bot somehow all requests to https:// URLs are answered by the server with a 302, redirecting to http. The wordpress site itself is configured to use https, and we see that in the pages that are generated the links are all https links. In the apache config there are no rewrite rules and no redirects. However, any request to a https:// URL is answered with a redirect to the equivalent http URL. And I really would like to know where these redirects are coming from, what is generating these redirects. I've increased the loglevel on the webserver to DEBUG, but did not get any info there. I tried to enable debug logging in wordpress per the recipy I found here: http://codex.wordpress.org/Debugging_in_WordPress But did not get a debug.log file in the directory where one should appear. I'm really at a loss here, and need to fix this urgently. Any hints as where to start looking? Apache is 2.2.14 on Ubuntu. There are several other virtual hosts on this server, using php and https without any problem... Edit: I created a small info.php script and dropped that in the webservers' root. Calling this yields the output of the script, no redirect is generated. This suggest that it's not the webserver, but wordpress that is doing it. A second thing I noticed is that the redirect comes with several cookies, one of which has "httponly" set. Could that be it?

• How do I configure Jetty (via jettyrunner) so that it names a character set in the Content-Type response header?

  - by Pointy

  I use Jetty (via the oh-so-handy Jetty Runner) for day-to-day web application testing. One thing I've recently stumbled on is the fact that I don't get a character set called out in the "Content-Type" response header all the time. I do get it in response to my application's XMLHttpRequest transactions, but not for plain old pages loaded by <a> links or whatever. I've read a little bit about how to set up a Jetty config file, but I've never been able to completely understand that; all servlet containers are complicated, and while Jetty is pretty simple it's just weird enough that I don't grok the overall idea. Thus, all I do to launch my app is to run the Jetty Runner .jar file with a couple of simple arguments to set up the port number and logfile path, and then I just give it the .war file to run. It works great — except for the missing character set :-) Anybody have a quick sample config file that might fix this? edit — oh if it matters, I'm running Jetty 7.0.0 RC3; I've also tried with a slightly newer version (still 7.something) with exactly the same issue. All my testing is on Ubuntu.

• Noisily rendered text in Firefox

  - by Notinlist

  It came to me in a week or so that certain pages (Facebook, StrackOverflow, some news sites) have text rendering errors in Firefox. As a workaround if I refresh the page, or simply select and deselect the buggy text, the unpleasant effect disappears. I don't have this effect in Internet Explorer or in any of my desktop applications. Windows 7 Pro 64bit (fresh) Firefox 19.0.2 (fresh) Ati Radeon HD 4600 Series (fresh drivers) Thanks for the help in advance! Update 1/2 I have only three addons: Forecastfox, Hungarian spell checking dictionary and Quick locale switcher. The latter two are installed after the effect appeared. I disabled the first individually and did not helped. But if I start my firefox with disabled addons I cannot reproduce the error. As far as I know this mode does not mean disabled plugins, which I do have (Adobe Acrobat, Citrix ICA Client, Google Earth plugin, Google update, Java Deployment Toolkit 6, MS Office 2010, MS Windows Media Player Firefox, Shockwave Flash, Silverlight, VLC Web). Update 2/2 If I disable all plugins and extensions I still have the problem. If I start Firefox with disabled addons then I cannot reproduce the problem.

• Google analytics ignoring "required step" in goals

  - by Matt Huggins

  I am A/B testing a landing page to see which converts better. The funnels are set up exactly the same in terms of the goal completion URL and funnel steps, with one exception: the first step (which is a required step) has a different URL to represent each of the two landing pages. Unfortunately, Google is tracking a conversion for both of these goals regardless of which landing page a user is reaching! It looks like the "required step" is broken...perhaps it is a deeper issue if others haven't noticed it, such as it only not working when the goal URL is the same between multiple goals. Here is an example of what I mean. Goal 1: Goal URL: /users/dashboard (head match) Funnel: 1. /homepages/index1 (required step) 2. /users/register 3. /users/edit Goal 2: Goal URL: /users/dashboard (head match) Funnel: 1. /homepages/index2 (required step) 2. /users/register 3. /users/edit As you can see, the only difference is step #1 of the funnel. Since I am A/B testing the landing page of the site, this should be the only difference. However, when I look at the goal page of Google Analytics, I see that the goal is being recorded for both of these regardless of the landing page being reached. The only tinkering I've done is attempting to wrap each funnel step's goal in ^ and $ characters for an exact regular expression match, but this didn't make a difference. Thoughts?

• Skipping nginx PHP cache for certain areas of a site?

  - by DisgruntledGoat

  I have just set up a new server with nginx (which I am new to) and PHP. On my site there are essentially 3 different types of files: static content like CSS, JS, and some images (most images are on an external CDN) main PHP/MySQL database-driven website which essentially acts like a static site dynamic PHP/MySQL forum It is my understanding from this question and this page that the static files need no special treatment and will be served as fast as possible. I followed the answer from the above question to set up caching for PHP files and now I have a config like this: location ~ \.php$ { try_files $uri =404; fastcgi_cache one; fastcgi_cache_key $scheme$host$request_uri; fastcgi_cache_valid 200 302 304 30m; fastcgi_cache_valid 301 1h; include /etc/nginx/fastcgi_params; fastcgi_pass unix:/var/run/php-fastcgi/php-fastcgi.socket; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /srv/www/example$fastcgi_script_name; fastcgi_param HTTPS off; } However, now I want to prevent caching on the forum (either for everyone or only for logged-in users - haven't checked if the latter is feasible with the forum software). I've heard that "if is evil" inside location blocks, so I am unsure how to proceed. With the if inside the location block I would probably add this in the middle: if ($request_uri ~* "^/forum/") { fastcgi_cache_bypass 1; } # or possible this, if I'm able to cache pages for anonymous visitors if ($request_uri ~* "^/forum/" && $http_cookie ~* "loggedincookie") { fastcgi_cache_bypass 1; } Will that work fine, or is there a better way to achieve this?

• nginx won't serve an error_page in a subdirectory of the document root

  - by Brandan

  (Cross-posted from Stack Overflow; could possibly be migrated from there.) Here's a snippet of my nginx configuration: server { error_page 500 /errors/500.html; } When I cause a 500 in my application, Chrome just shows its default 500 page (Firefox and Safari show a blank page) rather than my custom error page. I know the file exists because I can visit http://server/errors/500.html and I see the page. I can also move the file to the document root and change the configuration to this: server { error_page 500 /500.html; } and nginx serves the page correctly, so it's doesn't seem like it's something else misconfigured on the server. I've also tried: server { error_page 500 $document_root/errors/500.html; } and: server { error_page 500 http://$http_host/errors/500.html; } and: server { error_page 500 /500.html; location = /500.html { root /path/to/errors/; } } with no luck. Is this expected behavior? Do error pages have to exist at the document root, or am I missing something obvious? Update 1: This also fails: server { error_page 500 /foo.html; } when foo.html does indeed exist in the document root. It almost seems like something else is overwriting my configuration, but this block is the only place anywhere in /etc/nginx/* that references the error_page directive. Is there any other place that could set nginx configuration?

• What I should know about memory management?

• All computers on network get stuck waiting for some sites indefinetely

  - by zacaj

  This happens across three computers, running windows 7 and Ubuntu, firefox, opera, and chrome (all latest versions). I am connected to the internet through a Verizon wireless usb modem. When I try to open some web pages they will never finish loading (and usually never even show anything). The status bar at the bottom of the browser will display "Waiting for X" The servers it gets stuck on include: platform.twitter.com s7.addthis.com connect.facebook.net ajax.googleapis.com 2mdn.net Ive been getting away with just blocking them in AdBlock up until now, however the last two have been causing problems. There are some sites which require googleapis.com to load correctly, and some that wont ever load unless its blocked. eBay requires access to 2mdn.net to load pictures. On top of this its getting really annoying having to update AdBlock across all these computers whenever a new site pops up. I'm hoping there's some easier way to fix this? The different sites causing the freeze indicate to me that it's either a problem on my end (somehow?) or some server side software that got updated with a new bug?

• Free blog sites where the blogs can (if the template does) validate as XHTML Strict 1.0?

  - by Deleted

  I'm looking for a site where I may register a free blog and have the blog validate as XHTML Strict 1.0. On the surface this may seem like a trivial problem only related to the theme/template in use, but that's unfortunately not the case. One example of a provider which can't fullfill this requirement is Blogger. Altough the pages of the blogs there presents themselfs as XHTML 1.0 Strict it is impossible to actually comply with the requirements inheritied by that markup type in the blog (as the XHTML which is generated by Blogger makes the page as a whole invalid). I've sent a mail to Tumblr to see if it was possible with them, but so far my reply consists of them having forwarded my mail with a "suggestion" to the development department. I don't know if we had a communication error or if I'm actually going to receive a proper answer later. Time will tell. I haven't had time to investigate Tumblr myself, so they may very well be the solution to this problem. To sum things up, I'm looking for any provider: Of a free blog. The blog must have the capability to validate as XHTML Strict 1.0. With capability I mean that the system shouldn't get in the way of creating/using a theme which complies as XHTML Strict 1.0. Preferably is large or at least likely to stay around for a couple of years to come. But I'm willing to take my chances if none of the established providers are up to the task. Thank you for reading! I hope you know of any provider which would be suitable, preferably with proof by linking to a blog there which validates. I'm not looking for suggestions to look into, as there are far to many to investigate and far too little time. If you know of something for sure, I'd be very happy to know about it.

• sub application and virtual directory file permissions

  - by Zeus

  I have a website setup in IIS7, exampledomain.com. Under the application exampledomain.com lives a sub application cms. In a rather convoluted way, we have content in our cms system in this sub-app, under cms\content\{generatedfoldername}. So to access an image in this content, the full URL would be http://www.exampledomain.com/cms/cms/content/{generatedfoldername}/image.jpg, (yes, cms twice...) and this works just fine. Now, we have a virtual directory under the parent website, called stuff which points at the content of the cms. So I should be able to get to the image using the url http://www.exampledomain.com/stuff/{generatedfoldername}/image.jpg. Unfortunately this gives a server 500 error "There is a problem with the resource you are looking for, and it cannot be displayed." Whilst you do have to log into the cms system to access any of the admin pages within, I don't think the image files are protected by login, or else the first example URL wouldn't work, right? Also it's a server 500 error, rather than a 403. I'm sure I must be missing something obvious here- will the virtual directory be using the permissions defined in the parent application, or the subapplication to which it is pointing? Or is there some other permissions I may have missed? Sorry, that was a bit long, thanks for reading all the way down here! (I also must point out that I'm pretty new to the server management stuff.) edit: also, we have <location path="." inheritInChildApplications="false"> specified in the webconfig of the parent app, so it's hopefully not the issue described in this config file hierarchy article.

• Computer Won't Boot Properly, unless in safe mode?

  - by Mr_CryptoPrime

  I bought a computer today and booted it up, but when I did I only got a blank screen. I checked to make sure it wasn't the monitor by connecting it to my old computer...it worked. I then tried connecting my monitor to both DVI ports and found that the bottom one did work. However, now it just boots up and says "loading windows" and then when the login screen is suppose to come up the screen just goes blank and monitor says "no input, check cord" (or something like that). I tried reinstalling windows and then I was able to log on normally. I used the CD's and reinstalled all the drivers, then rebooted...now I am stuck right back where I started. I tried taking out the RAM and inserting into different slots, that didn't fix anything. I was able to boot up into windows using safe-mode. I suspected that my ATI Radeon 6950 was the issue and downloaded the drivers, but I can't install them on safe-mode. Someone said to install C++ distr. and I tried doing that to fix driver installation problem of "failed to load detection driver" but it wouldn't let me do that either. Please someone help me, I don't want to have to deal with the evil redtape of sending it back to get a replacement!

• Windows Server 2008 IIS7 - page requests randomly hang or timeout

  - by seb835

  I've just installed a fresh copy of Windows Server 2008 x64 with IIS7 and PHP (fast CGI). However, I'm noticing that after moving my web site from a similarly specified machine to this one, I'm getting issues. The issue seems to be that randomly, as I'm clicking through the web pages being served, the browser will suddenly hang saying "waiting for mysite.com...". Sometimes the page will then timeout, or finally resolve after 20 to 30 seconds, but maybe missing the CSS style sheet. Very strange, as this is the only website installed on this new server, and only myself using/testing it. Server is installed in the same data centre below the old server. Has anyone else had a similar problem? I tried increasing the max workers pool to 10 (from 1), but this has no effect. Seems to happen most frequently after 1 or 2 minutes of inactivity on the website, then trying to load/refresh a web page. Many thank for any info and help. Kind Regards, Seb

• SQL Server Replication Backup

  - by user18039

  Hi We have a new system that runs on SQL Server 2008 r2 64-bit. There is a primary on-line transactional processing (OLTP) database that accepts a high volume of updates from several thousand Point of Sale systems at stores around the country. In order to protect this vital function, I have decided to introduce a dedicated reporting database server - from which multiple users will run some pretty complex reports. I realise that there were a number of choices but I decided to use Transaction Replication as the mechanism for copying the data from the OLTP database to the new reporting database - one way replication. The solution has worked well in test. I'm now being asked what changes need to be made to the backup policy to cover the architectural changes. I have read pages such as MSDN:Strategies for Backing Up and Restoring Snapshot and Transactional Replication but I think these are overkill for my solution. In fact, my current thinking is that we simply need to continue making backups of the OLTP data and logs. If the Reporting db or any of the system replication (eg distribution) databases fail then it's no big deal - we can clear all down then re-create the replication. I realise that taking a complete snapshot of the OLTP would be time consuming (approx 5 hours) but I'd be more relaxed about this that trying to restore backups of the various data and log files in the correct sequence. My view is that the complex strategies set out in the MSDN article would only be the way to go for a more complex replication solution than I have, eg if there were multiple subscribers with 2-way replication. Would you agree? I'd be grateful for any advice. Many thanks, Rob.,

• D-Link wireless router losing outbound data

  - by gsteinert

  I have a Linux box running the Apache web server behind a D-Link wireless router (nothing fancy, just standard kit that comes with Virgin Media broadband). My issue is that when requesting web pages (from within the network or via the web), the back end of the page seems to be being dropped. For example, I tried to display a text-only file, and all I could get was the first 40-70% of the file (it changed slightly with each refresh). The apache access logs show that only part of the data was being sent (~6000 bytes instead of the 12000+ bytes of the file). Removing my router from the equation fixes the issue and I can download any files no matter the size with no problems. My theory is that the uploaded packets are either being dropped or held up by the config of the router. Is there anything I can do to alleviate the problem? (Perhaps a way of reconfiguring the router to upload packets harder/better/faster/stronger or an option in apache that provides a workaround) As a last resort I will get a second NIC for my Linux box and turn it into a router, but that would mean the box will be on 24/7... not the most ideal of circumstances.

• Hiding my location to websites with region-specific languages/content

  - by Tudor

  I just went to download Microsoft Secority Essentials and it enraged me as it redirected me to a site in my home language and not the default English. If I go to America, I don't want them to speak Swahili. It reminded me of all the other websites who try to do the same. I don't want my content in greek when I'm on vacation! I for one simply can't work on a computer unless the language is English (or unless there's a VERY good reason to change the language). Location aware content is only good for download mirrors, and even then I would rather pick from a list of countries myself. (or if you can't speak anything but your own language) I know websites get your location from your IP and ISP, but is there any way you can inhibit this behaviour on a browser level? Is there any Chrome/Firefox extension for it? Do I really have no choice but to hide my IP? There's all sorts of services that claim they're hiding your IP for free so that people can't log and trace your steps through the internet, but they're probably logging it themselves and making money off it. Why else would they be free? I've found that Firefox has an Option that says "Choose your preferred language when displaying pages". Haven't found anything for Chrome.

• Let varnish send old data from cache while it's fetching a new one?

  I'm caching dynamically generated pages (PHP-FPM, NGINX) and have varnish in front of them, this works very well. However, once the cache timeout is reached, I see this: new client requests page varnish recognizes the cache timeout client waits varnish fetches new page from backend varnish delivers new page to the client (and has page cached, too, for the next request which gets it instantly) What I would like to do is: client requests page varnish recognizes the timeout varnish delivers old page to the client varnish fetches new page from backend and puts it into the cache In my case it's not site where outdated information is such a big problem, especially not when we're talking about cache timeout from a few minutes. However, I don't want punish user to wait in line and rather deliver something immediate. Is that possible in some way? To illustrate, here's a sample output of running siege 5 minutes against my server which was configured to cache for one minute: HTTP/1.1,200, 1.97, 12710,/,1,2013-06-24 00:21:06 ... HTTP/1.1,200, 1.88, 12710,/,1,2013-06-24 00:21:20 ... HTTP/1.1,200, 1.93, 12710,/,1,2013-06-24 00:22:08 ... HTTP/1.1,200, 1.89, 12710,/,1,2013-06-24 00:22:22 ... HTTP/1.1,200, 1.94, 12710,/,1,2013-06-24 00:23:10 ... HTTP/1.1,200, 1.91, 12709,/,1,2013-06-24 00:23:23 ... HTTP/1.1,200, 1.93, 12710,/,1,2013-06-24 00:24:12 ... I left out the hundreds of requests running in 0.02 or so. But it still concerns me that there are going to be users having to wait almost 2 seconds for their raw HTML. Can't we do any better here? (I came across Varnish send while cache , it sounded similar but not exactly what I'm trying to do.)

• How do you permanently disable the 'This Connection is Untrusted' page on Firefox

  - by TheIronChef9

  I'm going insane. Can someone please help me to COMPLETELY DISABLE the 'This Connection is Untrusted' page on Firefox. Facts: I am running Firefox 23.0 on an Ubuntu machine (downloaded and installed ubuntu today) It is a work computer and I have to use my employer's proxy While visiting Webpages/webapps like Gmail or Google brings up the 'This Connection is Untrusted' page and I have to go through the whole tedious task of selecting 'I understand the Risks' and add Exceptions, etc. etc. The fact is, I don't care about the risks. I would rather this computer melt into the ground than have to see that page ever again. I want to dance naked in untrusted pages and not give a damn about the consequences. I just never want to see that page again. Ever. For some sites (eg. wikipedia), the css doesn't load and I end up seeing them in plain text. As a result these sites are completely useless. Wasted hours trying to solve this for stackoverflow.com. These issues happen on the Firefox on my Windows XP machine as well (also using the same proxy). I don't want to export/import certificates or create exceptions for every site that shows this bloody page. I just want this page gone. I don't want Firefox to tell me what's safe and what's not. Also, my system time and date are correct. I've also tried the lies on this page too with no good results. Edit: I've also tried the whole going into the Advance-Certificates-validation setup page and unchecked 'Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates' checkbox. Nothing happened even after restarting firefox or rebooting. I need help. Thanks.

• Expanding raidz vdev

  - by Blubber

  I'm currently planning on installing FreeBSD 9 on my home server. The machine has 4x 1.5TB disks, and at some point, when HDD prices drop I'll be upgrading to something bigger, perhaps 3TB. The disks are connected to an IBM ServerRaid m1015 in IT mode, this card has room for up to eight disks. Now here is the problem, currently the 4x 1.5TB will be connected to the m1015. Then when prices drop I'll be adding something like 4x 3TB, also connected to the m1015. No problem yet, I can just run 2 raidz2 vdevs and put them in the same pool. But, at some point the 1.5TBs will start to break, or I will have to upgrade them when the pool runs out of space. So I started researching if it's possible to expand a raidz vdev, and I found several pages explaining the same procedure, like this on SF: How to upgrade a ZFS RAID-Z array to larger disks on OpenSolaris?. So I went a head and tried that in vmware, I installed FreeBSD 9 and created 6 virtual disks, 3 of 1GB each and 3 of 10GB each. After building a raidz vdev of the 1GBs I replaced them one by one with the 10GB, but the pool did not increase in size. Is this a limitation of the ZFS implementation in FreeBSD? Or am I just doing something wrong?

• Does Google sometimes ignore "special" characters, possibly depending on your location or font type settings? [closed]

  - by RLH

  TLDR Google tends to ignore special characters in my search strings. Is there anything that I can do about it and is it, possibly, happening because Google makes certain assumptions based off of my default text-encoding settings and my location? I just posted this question over at StackOverflow. I had found a C preprocessor that I'd never seen before. As I should have done, I Googled it and tried to find out further information. I attempted various search terms which were all variations of "C Operator ##" (some times with and some times without the double-quotes.) Google didn't bring back anything of use so I posted my question on SO. As you can see from the comments, someone mentioned a search string (ironically one which I did try to search) and stated that I could have even hit the "I'm feeling lucky" button and have gotten my answer. The problem is I did search that, and the results that I received were far more basic and even after following the top results and searching the resulting pages, I could find nothing referencing the string "##". I'm not posting this question to complain but it does provide an empirical example of something I've seen before that really bugs me-- Google often ignores special characters in my search strings and the results are often useless. As a developer I often need to search for string values containing non-alphanumeric characters. Some characters (like the underscore or hyphen) can be used without trouble. However, other characters (such as the ampersand, carat, tilde and pound sign) are often ignored in my query strings. Is there a way to prevent this from happening so that I can get meaningful results from Google? NOTE I stay logged into Google and I live in the US. I wonder if Google detects some form of text-encoding setting or derives my results based off of certain, localized text-based assumptions. Regardless, I would like to for Google to search for what I give it. Is there anything that I can do to improve my results?

• Are there tools available for trimming PDF margins?

  - by Charles Duffy

  I have an ebook I'm trying to read in PDF format on a Kindle. Unfortunately, the page headers and footers have some content (page number and copyright info, respectively) preventing the device from scaling the actual text to match its usable area viewing area, thus leaving the actual content too small to read. Various tools are available which will trim off whitespace, but the Kindle already does this; my goal, by contrast, is to remove printed matter outside of a defined bounding box, and the only tool I've found for the purpose is moderately expensive commercial software. I could probably generate a mask in Inkscape; split out the individual pages using pdftk, apply the mask to each page individually (outputting to postscript), and recombine the numerous postscript files into a single PDF. However, this decode/reencode steps would be pretty unfortunate in terms of document size; something able to operate with a bit more finesse would be ideal. I have all major operating systems handy (Windows, several modern Linux distros, a Mac, etc) so solutions don't need to be constrained by platform. Suggestions? (I've reported the issue to the author, who mentioned it to his editor, who hasn't done anything about the issue over the course of more than a month, making the zero-work approach evidently nonproductive).
