Linux cannot up Ethernet after sleep

Sat, 28 Feb 2026 00:00:00 +0200

In a nutshell:

# ip link set eth0 down
# echo mem > /sys/power/state
# ip link set eth0 up
RTNETLINK answers: No such device

A couple of slackpkg+ tips

Wed, 25 Dec 2024 00:00:00 +0200

One tip is on an issue with https://slakfinder.org, another is about not upgrading some packages by default. They aren’t related to each other, but I’ve dealt with one and found a solution to the second one at about the same time. There is also an unrelated bonus section.

The tips are related to slackpkg+ (the link likely won’t open), which is useful if you have multilib installed because it allows treating it essentially the same as official Slackware packages which get masked. It’s not limited to multilib and allows managing any number of repositories in addition to the official one.

How to limit flag occurence count in CLI11

Sun, 16 Jun 2024 00:00:00 +0300

There exists a quite popular command-line parser for C++ called CLI11. It’s not without issues (e.g., compilation time is quite bad), however its API is probably one of the most convenient out there (really weird that other similar libraries aren’t doing the same).

I’m using it for a project and had a need for a flag that can be repeated but I wanted to limit number of times that it can be repeated. Couldn’t find any information on how to do this, but managed to figure it out, hence this note.

The fucking Firefox lag

Sun, 21 May 2023 00:00:00 +0300

Some time ago Firefox started to occasionally hang for maybe 20 seconds during which nothing was drawn on the window. Later I’ve noticed that it happened every time a context menu was about to be shown, same for some dialogs, all drop-downs and sometimes on opening of a new tab. I think it started after an update and naturally expected it to go away after another one. Sound also started to have issues at some point, but it wasn’t really a problem. The version in use is an ESR (102), but regressions happen in ESRs as well. Plus it didn’t work in a tiling WM, which also tend to manifest weird behaviours of applications. Yesterday, I’ve finally fixed it.

So why is it “fucking”? Keep reading…

Code review rules

Wed, 22 Feb 2023 00:00:00 +0200

Over the years I have contributed to various FOSS projects (both non-commercial and those owned by corporations) as well as proprietary ones. I’ve also played a role of a reviewer in all of those settings. Based on what I’ve seen and done I would like to propose some recommendations on how both sides can do better.

Benchmarking I/O ETA algorithms

Sat, 31 Dec 2022 00:00:00 +0200

Vifm can show some statistics about an ongoing file operation and recently it was suggested to add an ETA there as well. I have an issue with ETAs because of how wrong they often are, so the plan was to find out what’s the best way to implement one before proceeding. Unfortunately, I wasn’t able to find anything useful that could aid in making the decision. I found a lot of frustration about ETAs similar to mine, but essentially no recommendations that were substantiated with anything tangible, so I decided to compare different ways to compute an ETA myself.

Using Sumneko Lua Language Server in Vim via vim-lsp

Mon, 21 Nov 2022 00:00:00 +0200

I finally decided to give LSP a try in my Vim for the purpose of getting completion in Lua. I kinda hate that decision by now, but there are some results to show and I want to document all the shit I had to deal with along with a working configuration.

Front panel headphone jack and PipeWire

Thu, 02 Jun 2022 00:00:00 +0300

After upgrading to Slackware 15.0 I kept using Bluetooth for headphones and only later found out that sound through wires didn’t work if plugged into front panel. While advices on the Web immediately jump to module settings I realized that on 14.2 everything worked with Alsa and PulseAudio, so usage of PipeWire might have contributed to the issue.

Repository-specific commands

Mon, 29 Jun 2020 00:00:00 +0300

Automating typical tasks in your repositories makes life easier by relieving you from running same commands over and over again. However, eventually using the automation itself can start taking more effort than you feel it deserves. At the same time some things are so simple you don’t even try to automate them properly or maybe you’re not sure they are useful enough to warrant generalization, so they live and evolve in your shell’s history. These and some other cases can be handled better with commands/scripts that are local to a specific repository.

Don't trip over string optimizations

Tue, 31 Mar 2020 00:00:00 +0300

Optimizations are nice, but sometimes their effects can take you by surprise, especially if you’re not thinking about them while trying to debug an issue. If that’s the case, they can make your head hurt for a while. This post is about std::string class, but it’s far from being the only string class out there, so keep the outlined issues in mind while working with other implementations as well.

Prevent MPlayer from disabling display's powersave

Tue, 24 Dec 2019 00:00:00 +0200

MPlayer disables powersave for your screen when it has a video to play, which is what you want usually, but not always. In particular, the fact that powersave is disabled regardless of whether the video is running or being paused can be somewhat irritating if you’re watching something in multiple takes and just keep it paused in background for a long time to avoid writing down position at which you stopped watching.

How -f[un]signed-char can break your code

Fri, 25 Oct 2019 00:00:00 +0300

Most programmers are used to targeting x86 systems where char is signed char by default. It can lead to this assumption being baked into the code. Later, the code might break on a system where defaults differ, causing trouble. The first solution you might try to reach out for is -fsigned-char compiler’s switch, but there is a catch there which might or might not matter for a specific code base.

Why do new software tools look shiny?

Sat, 31 Aug 2019 00:00:00 +0300

It puzzles me when people get excited about some new tool which is just a rewrite of an old one. Usually it is written in a different language by its proponents and is more a testament to lack of fantasy rather than an indication of a need for one more copy of an old program. What’s more interesting though is an appeal these new implementations have for users which—I claim—are mostly superficial. Below is my take on some pros and cons.

Inventing grammar for GNU Make

Thu, 28 Feb 2019 00:00:00 +0200

For the purpose of making zograscope support parsing of more than just one language, there was a need to pick a language that is substantially different from C (the first one supported). GNU Make language certainly looked like an interesting option right from the start and it’s a tool that I use regularly. However, finding a grammar to implement it turned out to be a problem. Since grammar wasn’t found, it was created.

More than 256 color pairs in curses

Tue, 05 Feb 2019 00:00:00 +0200

Those who used curses at least once to draw something in color had to notice that setting colors happens in pairs (foreground and background) and number of such pairs is limited. These limitations and some basics about upgrading code to lift one of the limits will be described in this short post.

New tool: pipedial (terminal element picker)

Thu, 24 Jan 2019 00:00:00 +0200

pipedial is one more tool for selecting something in console. Existence of many such tools might be a valid criticism against creating more, but not for those who think in terms of h/j/k/l.

Weboob as an alternative way of browsing WWW

Fri, 28 Dec 2018 00:00:00 +0200

Turns out there is a nice project that provides another way of accessing some parts of the Web that doesn’t require using a browser. It’s called Weboob.

Take off GitHub with RocketGit

Mon, 10 Dec 2018 00:00:00 +0200

Announcement of GitHub being acquired by Microsoft prompted many people to consider migrating away from it. Yet this isn’t really something new as one could hear similar thoughts expressed even before that (see) and I personally chose not to publish a fork of one popular project on GitHub months before the announcement.

The sad truth is that there aren’t that many real alternatives there and even if one reaches for self-hosting solutions instead of a third-party service, they tend to be disappointing in some way.

Recently I have discovered a project which looks like it might be a solution I was looking for.

Propaganda in IT: Microsoft Buys GitHub: The Linux Foundation’s Reaction

Tue, 12 Jun 2018 00:00:00 +0300

It’s been over a week since MS declared that it buys GitHub, which generated a lot of discussions, but one of the most interesting pieces is a post from The Linux Foundation. It is quite short and at the same time seems to be constructed to sway people in a certain direction that can serve as a nice example on propaganda. Let’s take a look at how things are worded, what is omitted and how the rest is framed.

Come to terms with computer terms

Mon, 26 Mar 2018 00:00:00 +0300

There are many things which people get wrong over and over again. People seem to care enough to repeat these mistakes out loud regularly, but apparently not enough to actually check correctness of the information or at least question it. Let’s deal with some claims of this sort from IT field which bug me personally.

How to make perf TUI work

Tue, 14 Nov 2017 00:00:00 +0200

perf is a quite handy tool to quickly measure performance of your application on GNU/Linux without recompiling it. The only issue seemed to be inconvenience of viewing report in a pager. It turned into concern after realising that it should start TUI on perf report by default, but for some reason it didn’t.

Updating mail receiving stack

Sat, 09 Sep 2017 00:00:00 +0300

Calling it a “stack” is probably too much, but fetchmail and procmail seem to go together and they are both subject for replacement for good reasons.

After finally deciding to replace fetchmail and procmail with something newer, came realization that there aren’t that many choices out there and still quite a lot of people continue recommending fetchmail+procmail. This post is here to contribute to transferring to potentially more secure software.

Conditional ignorance in C++

Wed, 05 Jul 2017 00:00:00 +0300

It just so happened that I watched several C++ talks that mention upcoming feature of C++17 called “If statement with initializer” all in a relatively short time frame. Unfortunately, there was another common trait among all of these presentations, which is the topic of this post.

The big list of Vim-like software

Sat, 13 Aug 2016 00:00:00 +0300

A more interactive version of this post is available at https://vim.reversed.top/.

Not updated since August 14, 2022; future updates only in the interactive version.

There are a number of similar lists already, but they usually lack grouping and miss pointing out things that are of interest for the author of this one. So based on those lists and other sources here’s another one, which actually might be the biggest so far.

The listing is followed by some critique, which obviously comes from personal views and experience, so don’t expect to agree with everything in that section.

Skipping standard C++ library during debug session in gdb

Thu, 26 May 2016 00:00:00 +0300

UPDATE: if you have new gdb (7.12.1), scroll to the bottom.

Ability to inline functions and methods in C++ is one of the reasons programs in C++ are so fast. As such code provided by libraries effectively becomes part of its client application and the great and mighty gdb knows what inline functions are, this might cause inconveniences during debugging. The problem is that while stepping into a method one can get into one of many inlined functions that aren’t interesting.

ncurses wrappers for C++

Sun, 24 Apr 2016 00:00:00 +0300

curses is a well known set of libraries (with mostly common API) for creating TUIs. What is significantly less known though is that ncurses implementation comes with C++ wrappers for its C API.

Converting Vim documentation file to HTML

Wed, 13 Jan 2016 00:00:00 +0200

Vim has a great documentation for sure. Part of its greatness is documentation format itself. The only difficulty is that it can’t be easily converted to and from other formats, which might be sometimes desirable or at least useful to provide same documentation in different form. In particular, conversion into HTML is sometimes useful and although there is an HTML version of Vim documentation, the tool with which it’s produced has never been made public. There is another way around it without the need to write such a tool from scratch.

C++ manual pages

Tue, 05 Jan 2016 00:00:00 +0200

One of the great things about C is that its documentation is available locally via man command. That’s very convenient and one might expect to get the same for C++, but (say) man std::adjacent_difference will usually just print:

No manual entry for std::adjacent_difference

Luckily, there are ways to fix it.

Switching from tmux to GNU Screen

Sun, 08 Nov 2015 00:00:00 +0200

I was postponing learning how to use terminal multiplexers for a long time until one day had to test integration with tmux, which required learning it. So I was using tmux since then and always thinking whether I could do better by using GNU Screen instead. After all, most of GNU applications turn out to be quite versatile and extremely useful, so why GNU Screen wouldn’t have these properties? This is especially reasonable question if one recalls that tmux was modeled after GNU Screen.

Enabling output colorization in GCC

Sun, 25 Oct 2015 00:00:00 +0300

I was waiting for GCC 4.9 for a while to get my hands on colorized color output, but after it became available in Slackware error output didn’t magically become colored. This might not be the case for other distributions, but since it took me some time to make this work and after more than six month I still can’t find any related posts on the Internet right away here’s a short note.

C++11+ aggregate initializer surprise

Sat, 24 Oct 2015 00:00:00 +0300

There is a nice thing in C++ called friendship between classes or classes and functions, which is used to put several entities in one security domain by allowing “friends” to access private fields. This language feature is usually criticized as something that breaks encapsulation, which is not actually true as C++ is multi-paradigm language rather than being just OOP-language and such exceptions should be viewed as another way of doing things, not as something “wrong” (which is very subjective, by the way).

Range iterator for Boost.PropertyTree items

Sat, 15 Aug 2015 00:00:00 +0300

The other day I was looking for a way to obtain fully qualified names of items in Boost.PropertyTree in sorted order, but basically found only one post on the subject, which demonstrated recursive traversal of a tree in more detail than iteration over all keys. What I wanted is an iterator based solution, which could be employed in C++11 range-based for loop. So I ended up writing one.

Clang by example: Detecting wrong first include

Thu, 23 Apr 2015 00:00:00 +0300

Introduction

There is a well known (or at least I hope that it’s well known) good practice to include header that corresponds to the current source file before including any other headers. It’s recommended by multiple C++ coding style guides (for example by Google C++ Style Guide) and indeed makes sense to follow.

To put it short: it makes finding incomplete headers really easy. If you forget to include required header, corresponding source file just won’t compile. This way there will be no hidden (implicit) dependencies among modules of a project as well as dependencies on system headers. Below is a simple example that demonstrates such situation.

Why restoring signal handlers is important

Sun, 05 Oct 2014 00:00:00 +0300

I experienced strange failures of some commands in gvim (e.g. errors on closing window of :Gblame) for quite a while, but couldn’t figure out why the hell their occur. Overall it probably took more than 20 hours to identify the issue and solve it not causing any other issues to arise. At the end of the day it took single line to solve the issue…

Fixing CIFS mounts in Slackware

Mon, 29 Sep 2014 00:00:00 +0300

I remember CIFS/SMB working fine for me, but it occasionally mysteriously didn’t work on some machines even with 100% correct configuration (e.g. line in /etc/fstab). It actually happened not only on Slackware, but also on Debian, though not sure what was causing issues there.

How to install data directory with automake

Sun, 28 Sep 2014 00:00:00 +0300

I thought that adding directory to pkgdata_DATA variable in Makefile.am file would be enough, but make install command gave this error:

/usr/bin/ginstall: omitting directory ‘../data/vim/’

How to make bootable win7 installation USB stick in GNU/Linux

Thu, 18 Sep 2014 00:00:00 +0300

For most bootable ISO images one of two approaches works:

dd if=image.iso of=/dev/sdx if image is a hybrid CD-ROM/HD image.
Extracting image via UNetbootin.

However, none of this works for Windows setup disks, even if you do this on Windows. Usually I go with UltraISO’s “Write hard drive image”, which works fine. But there is no UltraISO for GNU/Linux and one has to go another road.

Fix graphic errors after replacing NVIDIA card with Intel Graphics

Sun, 07 Sep 2014 00:00:00 +0300

After upgrading motherboard and its components, regular graphics (windows, video) worked fine with Intel HD Graphics, but trying to run something like glxgears displayed nothing but blank window. It was strange as Intel drivers are open source and known for their good work in GNU/Linux.

Decrease LILO kernel load time

Tue, 02 Sep 2014 00:00:00 +0300

Opened my LILO configuration file (/etc/lilo.conf) recently to take a look at video mode options and noticed this line:

#compact        # faster, but won't work on all systems.

Clang by example: Detecting unused functions

Thu, 28 Aug 2014 00:00:00 +0300

Introduction

This memo provides description of a tool that scans a set of source files looking for two types of functions declared with external linkage:

Those that are defined, but completely unused.
Those that are used only inside same translation unit they are defined in.

csplit: splitting text files by separator line pattern

Wed, 23 Jul 2014 00:00:00 +0300

To split files by number of bytes or lines there is standard split command, but how to break file into pieces of variable size that are delimited by a separator? Search revealed csplit tool, hence this quick overview with a small example.

Prefer plain text format over HTML in mutt

Tue, 22 Jul 2014 00:00:00 +0300

Although this subject is covered in multiple sources, it’s hard to find it for some reason or at least it wasn’t that easy for me. That’s why I repeat it once again here and provide links to more verbose explanations.

How to add route for PPTP tunnel automatically

Mon, 07 Jul 2014 00:00:00 +0300

Had an issue with setting up correct routing rule for VPN network through PPTP.

rexima: couldn't open mixer device

Sun, 06 Jul 2014 00:00:00 +0300

After installing Slackware 14.1 on a new machine, I got unexpected output when tried to run rexima interactive mixer (by the way, it’s in extra section of Slackware packages, so search might silently skip it, just do slackpkg install rexima to install it). The output was:

$ rexima
rexima: couldn't open mixer device.

Removing sendmail from mail receiving chain

Fri, 04 Jul 2014 00:00:00 +0300

One of common ways to receive mail includes using sendmail as an MTA. This causes some inconvenience especially when it’s the only purpose sendmail is installed for. To be able to receive mail sendmail deamon must be running all the time, which also means that it consumes some (small) amount of resources. It’s not a problem at all (even though it slows down system startup a little bit), but why keep it if we can live without it?

How to make tabs visible in git diff

Sun, 22 Jun 2014 00:00:00 +0300

I’m a bit tired looking at diffs like the following:

         for (int i = 0; i < 3; ++i) {
-        for (int h = 0; h < 4; ++h) {
+                for (int h = 0; h < 4; ++h) {
                         for (int k = 0; k < 4; ++k) {

Can anybody tell whether spaces were replaces with tabs or tabs were replaced with spaces without knowing anything else about the code? Probably, not.

Clang by example: Detecting postfix operators in for loops

Fri, 02 May 2014 00:00:00 +0300

Introduction

Foreword

The LLVM project has been started back in 2000, but became widely known and used quite recently, about 4 years as of now (2014). It’s used by hardware manufactures to implement programming languages for their products as well as by software engineering companies to develop their own programs. There are two main reasons why LLVM gained such popularity:

Fix constant rebuilding of static libraries by GNU make

How to profile python application packaged via py2exe

Tue, 04 Feb 2014 00:00:00 +0200

Simple profiling using standard `cProfile` module

Usually a command similar to the one below is used to profile an application:

How to recompile source file on each build using make

Sat, 18 Jan 2014 00:00:00 +0200

Motivation

It’s sometimes useful to see precise date and time an application was compiled. So such information should be embedded into application at compile time and displayed on user’s request.

How to disable subtitles in mplayer by default

Sat, 16 Nov 2013 00:00:00 +0200

Pre-history

I really like mplayer because:

it is very powerful;
yet quite easy to use from command-line;
has sane defaults;
no GUI which just stands between me and video I want to watch.

So far, so good. The only thing that bothered me for a while is that subtitles are enabled by default.

How to define `_GNU_SOURCE` correctly with autoconf correctly

Fix tmux hang in X

Wed, 25 Sep 2013 00:00:00 +0300

Recently I needed to use tmux. Turned out that it wasn’t even installed on my system, which, of course, wasn’t a problem. After it was installed and ran I was presented with a prompt that didn’t responed to anything. The only thing that worked well was pkill tmux.

Mainly for historical reasons, vifm contained the following pieces of code:

Out-of-class overload of unary operators in C++

Mon, 29 Apr 2013 00:00:00 +0300

This may sound strange, but it seems that I have never thought about overloading of unary operators in C++, which are not implemented as member functions. It’s not like it sounds strange or incorrect, I just never wanted to do it. So, just to be able to say “I did it at least once”, lets try it out on a very basic example with overloading of postfix increment operator:

Flattened aggregate initializers in C and C++

Sun, 28 Apr 2013 00:00:00 +0300

Today I found an interesting statement on one of forum pages of LOR: initializers of inner aggregates can be flattened.

How to set `xterm-256color` type of terminal in xterm on Slackware Linux?

Sun, 14 Apr 2013 00:00:00 +0300

Recently support for processing escape sequences in preview window was added to vifm. So I added highlighting of source code in my preview window using highlight tool specifying -O ansi to make it generate ansi compatible escape codes. But some of syntax group obtained the same color, because I had my terminal configured to display up to 8 colors. To solve the issue, I decided to start using xterm-256color terminal mode in xterm. Here’s where all fun began.

How to operate on selection in mutt?

Sat, 30 Mar 2013 00:00:00 +0200

This is a very simple thing, but I just can’t make myself remember it. So here is how it’s done:

How to merge mailbox files of mbox format?

Sat, 30 Mar 2013 00:00:00 +0200

This sounds like an easy task at first. But after looking on the Internet for a working and ready to be used solution, it turned out to be not so easy to find. There were some old scripts in python, but they didn’t look very promising to me. So after spending some time on search this answer to my question was found.

How to share code among several Web-service applications written in Java

Fri, 09 Nov 2012 00:00:00 +0200

Some time ago I’ve spent a lot of time trying to figure out how one can share common parts of code in two Web-services running in Apache Tomcat. What I wanted is to move several packages to a separate Eclipse project and refer to it from several other projects. Somewhere on the Web a nice list of options to achieve this was found. All (or almost all) of them were connected with the Classpath settings pane in the project options. But unfortunately no matter what Classpath options I set, it didn’t work. I’ve also tried exporting project with the common functionallity to a jar file and linking to it from other project. That didn’t work either, that jar file wasn’t deployed to Tomcat server.

Double brace initializers in Java

Thu, 18 Oct 2012 00:00:00 +0300

Unfortunately, some features of well known programming languages are much less known than others. Eventually, those unknown features are quite powerful and useful. Today I’m going to describe so called “double brace initialization” in Java, which is quite similar (and more powerful) than object initializers of C#.

strchr() finds zero character

Wed, 17 Oct 2012 00:00:00 +0300

As any other programmer once in a while I find some new tiny but quite useful trick, which I then apply to my sources. One of such trick is using of strchr() function to compare if a value of type char equals to one of values.

Making ~/.inputrc work in slackware

Sat, 13 Oct 2012 00:00:00 +0300

Today I accidentally trapped on this part of Arch Linux wiki page on Bash. And decided to try putting set show-all-if-ambiguous On to my ~/.inputrc, which was created for this.

Configuring keys in less

Thu, 11 Oct 2012 00:00:00 +0300

Since I’m using Vim and terminal constantly the only right way of going through command-line history in my world is using Control-P (<c-p> or ^P; to go backwards) and Control-N (<c-n> or ^N to go forwards).

How to connect a computer behind NAT to another computer behind NAT using ssh

Wed, 10 Oct 2012 00:00:00 +0300

I was wondering how can I connect to my laptop from work for some time, but didn’t know how to do that without using VPN. I even decided that it’s impossible to do something simple, but then… I realized that a third party server to which I have access through ssh can be used for this.

An issue with colour prompt in bash

Tue, 09 Oct 2012 00:00:00 +0300

Prehistory

Once I read somewhere that it’s possible to add some colours to your shell’s (bash in my case) prompt using escape sequences. I thought that it will greatly decrease time one spend finding the beginning of a command that was just run. Prompt colouring is also useful to distinguish between root and regular user prompt. So after some experiments with echo command, I added this line to my ~/.bashrc file:

Browsing directories using Vim's wildmenu

Mon, 08 Oct 2012 00:00:00 +0300

Today I accidentally found a very unexpected thing in Vim. While trying to make wildmenu disappear I hit some of arrow keys and great truth was uncovered to me:

one can browse file system in wildmenu using arrow keys!

Enabling code highlighing in jekyll

Mon, 08 Oct 2012 00:00:00 +0300

It’s not hard to do, but not as easy as one might expect. So here are the main steps one need to follow to make code highlighing work:

Exception specifiers and finally keyword in Java

Mon, 08 Oct 2012 00:00:00 +0300

Here is part of code I wrote once:

String execute(String data)
{
    String result = null;
    try {
        final Execute execute = new Execute();
        execute.setId(id);
        execute.setData(data);
        result = cmiss.execute(execute).getData();
    } catch (RemoteException e) {
        e.printStackTrace();
    } catch (CommandFault e) {

This day I finally made a decision to start posting some notes on computer related stuff and mainly about how I solved some minor issues with software. Several month ago I already picked statically generated sites and GitHub pages as a hosting (I don’t expect other people to read this, I just don’t want to forget anything of it :-), so such hosting is enough for my needs). So I found a post Setting up Github Pages written by David Winter and started following steps described there.
