The whole web is full of pseudo guides on how to properly - that is the key word here - configure Nginx to perform caching alongside with PHP-FPM, but every single one of them fails to mention some minor steps resulting in a borked half functioning implementation. For example, not a single one mention the necessity to edit /etc/php.ini and set session.use_cookies to 0. Too bad that without doing so caching with WordPress in combination with certain plugins or themes (for example MainWP or Enfold theme) is completely not working; the following headers get added to every HTTP response:

Pacman as long as I know does not provide any method for sending an email notification when there are updates available. SSH into the Arch box just to find out if there are updates available is really annoying so I wrote a simple bash script to do the dirty work on my behalf. [root@arch ~]# cat /etc/cron.daily/check4updates.sh #!/bin/bash HOST=hostname DOMAIN=domain SUBJECT="System update: $HOST@$DOMAIN" EMAIL_ADDR="name@domain" ### Query pacman for available updates updates_raw=$(pacman -Syu <<< n) if echo $updates_raw | grep "

EXT4 is usually pretty good at keeping files fragmentation at minimum, but, sometimes, especially if dealing with really huge files, some fragmentation may actually occur. Luckily EXT4 supports online defragmentation, command fsck displays, among other things, fragmentation percentage: [root@fedora ~]$ fsck.ext4 -fvn /dev/sda1 e2fsck 1.42.12 (29-Aug-2014) Warning! /dev/sda1 is mounted.

Yum provides a very useful package called “yum-cron”, its most publicized feature is the ability to enable yum to run nightly cron scheduled packages upgrades. I honestly don’t really think it is a good idea at all to let the system manage updates by himself but yum-cron can be used for another bunch of tasks, the most interesting one being: send an email if there are updates available. yum install yum-cron Configuration is actually pretty simple.

Postfix configuration Install the required softwares: $ yum install postfix postgrey dovecot fail2ban spamassassin spamass-milter-postfix opendkim Create TLS certificate, key and CA authority (replace “mail.domain.tld” with valid domain name): $ mkdir /etc/postfix/ssl $ cd /etc/postfix/ssl $ openssl genrsa -aes256 -out mail.domain.tld.key 4096 $ chmod 600 mail.domain.tld.key $ openssl req -sha256 -new -key mail.domain.tld.key -out mail.domain.tld.csr $ openssl x509 -sha256 -req -days 1825 -in mail.domain.tld.csr -signkey mail.domain.tld.key -out mail.domain.tld.crt $ openssl rsa -in mail.

First off, I failed so there will not be any kind of walk-through or guide. Hardware/software setup is sub-optimal and is for sure part of the problem for at least three reasons: 1. as primary display adapter I use an Nvidia GTX 750ti; 2. I use Nvidia proprietary driver because nouveau support for newest graphic cards isn’t good (this is an understatement to say the least); 3. it isn’t completely clear if Intel Z97 chipset supports VT-D or not and if it does on what level it does.

Fedora 21 and MTP

In order to be able to mount a MTP device (in my case it is a Oneplus One) in thunar file manager the following packages are needed: simple-mtpfs libmtp fuse fuse-libs gvfs-mtp. After installing the previous listed packages restart the system. Once installed the device can me be mounted with “simple-mtpfs directory”, unmounted with “fusermount -u directory” or mounted with thunar/gigolo/etc.

When playing html5 videos with my 1+1 (Cyanogenmod 11 – snapshot M11 – Android 4.4.4 with ART runtime) using Firefox 33.1 (version 34 does not fix the bug either) audio works fine while video is completely corrupted with grey artifacts all over the place. The problem appears to be quite common and is not only circumscribed to 1+1. The best workaround so far is type “about:config” in the address bar, search for “media.

OnePlus One

Two weeks ago while wasting time on the interwebs I found by accident a couple of OnePlus One invites. To be honest I wasn’t planning on buying a new phone since my previous Nexus 4 is still serving me well but seeing OPO price (299 € for the 64 GB one) and specs I said: well, fuck it. So far I like it very much, the bigger screen makes general usage more enjoyable and battery life is significantly better than Nexus 4, it lasts 2 days without many problems.

Everyone who knows me a little bit knows how much I dislike Google but this time we really should thank them for taking a real step toward a more secure web. They are finally moving away from SHA-1 to the much more secure SHA-2, more info can be found here: http://googleonlinesecurity.blogspot.it/2014/09/gradually-sunsetting-sha-1.html .:.
