A 200 GB microSDXC card? Yes, I can haz that!

The top (in terms of capacity) microSDXC card in the market can hold 128 GB of stuff. That’s a lot of stuff. Starting from the second quarter, that capacity will go up by 56%, thanks to a new addition to that line of SD cards by SanDisk. A 56% jump in stuff-holding capacity means that a storage device the size […]

Dual-boot Linux Mint 17.1, Windows 7 on a PC with UEFI firmware

After Linux Mint 17 was released back in mid-2014, I published How to dual-boot Linux Mint 17 and Windows 8 on a PC with UEFI firmware.

Configure OSSEC to not email alerts on IPTables denied messages

The tl;dr of this article is: It shows how to configure OSSEC, a host-based intrusion detection system, to not send email alerts whenever IPTables rejects or denies a traffic source. The more detailed form follows. So I use OSSEC to monitor and protect my cloud servers, which gives me a lot of confidence because OSSEC keeps me informed about what’s […]

How  to delete Superfish from Lenovo computers permanently

How to delete Superfish from Lenovo computers permanently

So Lenovo has been reeling from the self-inflicted wound called Superfish, VisualDiscovery or WindowShopper. No sympathies from me, buster. What else have you done in the past that nobody found out? If you have no idea what Superfish is, here’s a very brief summary. Superfish is an adware installed on some Lenove consumer computers. The actual name is WindowShopper or […]

The ideal value of listen.backlog when setting PHP-FPM pm = ondemand

I recently wrote about the impact that setting how PHP-FPM’s process manager controls child processes from dynamic (pm = dynamic) to ondemand (pm = ondemand) has on RAM usage. You may read the article at How to reduce PHP-FPM (php5-fpm) RAM usage by about 50%. One other interesting PHP-FPM setting I got to learn a little bit more about while […]

How to reduce PHP-FPM (php5-fpm) RAM usage by about 50%

PHP-FPM is the FastCGI Process Manager for PHP. On Unix-like operating systems, including Linux and BSD distributions, PHP-FPM is enabled by installing the php5-fpm (Linux) or php56-fpm (FreeBSD 10.1) package. The problem with PHP-FPM is that the default configuration and that promoted by numerous blogs chews up too much resources – RAM and CPU. The server that powers this blog […]

For an editor, Atom uses way too much RAM

For an editor, Atom uses way too much RAM

For some time now I’ve been using Atom as a replacement for Kate, KWrite and GEdit, depending on the desktop environment I’m using. That’s because it’s much easier and faster to take notes when you’re formatting with MarkDown. If you’ve never heard about Atom, it’s a text editor from the folks at GitHub and officially described as a “hackable text […]

How to configure Ubuntu 14.04 server to forward root mails to your email address

This short tutorial shows how to configure a Ubuntu 14.04 Cloud server to forward system-generated mails sent to the root account to your email address. Why would you want to forward mails sent to root to an email address? Because most properly-configured Cloud servers are managed using a (normal) user account with sudo (root) privileges.

What I can say about KDE Plasma 5 that I can’t say about Windows 8

I’ve never really had the time to explore KDE Plasma 5 since it was released back in July 2014. I’ve played with it a bit, but not much. Now that it’s at version 5.2 and at that stage when its deemed almost ready for primetime, that is, ready to replace all aspects of KDE Plasma 4, I decided to kick […]

Why did this server run out of disk space?

Less than two hours after I logged into the admin end of this website, which is powered by WordPress, the site went offline, with a 502 Bad Gateway error. What the…? So I logged in via ssh and noticed a serious lag between when I type a letter and when it appears on the screen. I’ve got a problem. And […]

Getting to know the pkg audit command on PC-BSD and FreeBSD

If you’re new to FreeBSD and PC-BSD, you might not yet be aware of all their package manager’s many commands. Nobody expects you to, at least not initially. Pkg is that package manager and one of the its many commands I think you should get to know asap is the audit command. It’s used to audit installed packages against known […]

Raspberry Pi 2 vs Creator 120

Raspberry Pi 2 vs Creator 120

The Creator 120 and the Raspberry Pi 2 are single-board computers designed for developers and hobbyists. The Creator C120 was announced in late 2014, but started shipping at about the same time that the Raspberry Pi 2 was announced/starting shipping, which was just last week. I haven’t purchased a Raspberry Pi 2 yet, but I received a Creator 2 from […]

Two things I’ve learned from using Tor Browser

Two things I’ve learned from using Tor Browser

So for the past three months I’ve been using Tor Browser to surf the Web, not as a primary browser, but as a secondary browser. Firefox is my primary browser. Together with using StartPage as my search engine, I feel much better about my privacy while surfing the Internet. Using Tor Browser leads to a tad slower browsing experience, but […]

These reCAPTCHAs where not meant to be read by humans

A reCAPTCHA is supposed to make business tough for bots yet easy for humans to decipher. But we all know how annoying those things can be – for humans. That has led to some not too successful attempts to make them less so. A more recent effort is No CAPTCHA reCAPTCHA, but it didn’t really solve the problem that it […]

How to install the latest OpenSSH on Windows 7 and Windows 8

Occasionally I have to run an installation of Windows 7 or Windows 8 on one of my computers, which means having to copy files between it and the Linux computers on the network. That’s when I realize how difficult it can be to use a default installation of Windows, especially from its command prompt (line), where I tend to spend […]
