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 […]

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 […]

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. So unless you switch to […]

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 […]

MIPS Creator C120 development board and Debian 7

Back in December 2014 I won a Creator C120 single board computer from Imagination Technologies, a technology outfit based in Hertfordshire (UK). The Creator C120 is a development board for Linux and Android. It’s powered by a dual-core MIPS32 CPU (1.2 GHz) and a PowerVR SGX540 GPU. Add to that 1 GB of RAM, 8 GB NAND Flash, two USB […]

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

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 […]

The cheapest service is TransIP, which […]

Wget and the user agent option

Wget is a command-line utility for downloading files. The official description on its man page on my Linux distribution says that it is “free utility for non-interactive download of files from the Web”, and that it “supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies.” It especially comes in handy when I need to download an […]

Ubuntu Core beta, a version of Ubuntu for Cloud deployment that comes with snappy a system and application management utility with support for transaction updates, was released just a few hours ago.

Mark Shuttleworth has announced a beta release of Ubuntu Core, a version of Ubuntu server for the Cloud that does not use debs or apt-get for system and software management. What, then, does it use?

Use Tor Browser, get your computer blacklisted

Use Tor Browser, get your computer blacklisted

For the past few years I’ve been using a URL shortening service called ur1. It is a GPL-licensed URL shorterner from StatusNet Inc.. Why employ the services of goo.gl, t.co and bit.ly If I can do just as well by using a similar service from super-friendly folks? But I was surprised today when I tried to use it from Tor […]

Opera 26 released. Install it on Linux Mint 17.1 and Ubuntu 14.10

I don’t quite remember the last time I used Opera browser, but it’s been a very long time ago. I didn’t even think that the company is still developing a Linux version. So, surprised I was when I read that Opera 26 has been released for Windows, Mac and Linux. Even more surprising is this line from the FAQ about […]

“No CAPTCHA reCAPTCHA” is as annoying as reCAPTCHA if…

When completing an online form, proving that you’re not a robot can be very annoying. Sometimes even frustrating, especially if the website uses reCAPTCHA or a similar implementation of a system that asks you to decipher some cryptic text. I don’t use reCAPTCHA on this website, but I do encounter it on other websites. So it was heart-warming to learn […]
