Sosh ne fonctionne pas par défaut sur LineageOS et le service client a été incapable de me dépanner.
Il semble que LineageOS se distingue par le fait qu’on séléctionne un APN alors que Sosh veut qu’on en paramètre deux.

The computer has more options for stitching photos together than digital cameras have. Hugin Panorama Creator is free software and gives excellent results. However, to work correctly, Hugin needs the correct information for the lens used to take the photos! It is uncanny how inadequate lens data can impede Hugin’s algorithms to the point of rendering them absolutely useless.
The Fairphone 2 is not actually a digital camera for a start, and it is a niche phone at that. No wonder, that Hugin knows nothing about its lenses.

Personal accounting management is a tedious task: logging in to each bank’s web portal, checking for new PDF documents to download, then downloading for each account a “computer-friendly” record of transactions since the previous visit. And this is only to get the data…
All banks seem to agree on using the PDF format for “official communication”. For files intended to be imported into accounting software, however, anything is possible: csv, qif, ofx, or even nothing (that’s Oney…). Besides, the downloading process is not always satisfactory: the HTML forms to fill may be a bit buggy, the downloaded files sometimes have the wrong encoding, the included labels may not be as informative as those found on the web site…
Then I discovered boobank, from the Weboob software collection. This awesome tool can automatically login to each bank, and then convert the web site’s paged list of transactions into a standard format, such as ofx!

So… You were aboard a space-ship, and you crashed on a planet after hitting an asteroid. Welcome to the excellent game Blackvoxel!
As we saw in the first episode, from the wreckage you salvaged a base machine, which is the foundation on which you slowly rebuild the technology and equipment you were used to.

(yes, the title is a nod at something… guess what!)
You are aboard a space-ship, and you crash on the nearby planet after hitting an asteroid. Thus begins the tale of Blackvoxel. From the wreckage, you salvage a base machine, and you are still under the protection of your space-suit. Much like Matt Damon in The Martian, you are alone, and you have to make do with your environment and the salvaged equipment…

The IRIScan mouse is a neat little device! Its scanning function works really well and fast, for such a little piece of hardware, and the mouse function is surprisingly familiar: no extra weight, no extra bulk. It could be perfect.
But…

The Chrome web browser won market-share fast, and still is. But people tend to forget who is behind Chrome.
Now Google (or should I say Alphabet?) decided that their Chrome browser feeling faster is worth breaking web sites and going against the established standards that make the Web an open platform. That’s bad.
I’ve been using Firefox since it first appeared, not because it is the fastest, nor because it is the best, but because it is free software, backed by an organisation that pursues its users’ best interests and protects their privacy. Here’s one more reason to do so, if one was needed.
The icing over the cake is that Firefox is getting really fast! If you’ve been using Chrome, think again…

Yeah… sorry about that… The long-awaited change of server that I had been planning for more than a year has finally happened :-) It took some time, and things are coming back online one piece at a time…
On the good side, Git has become easier to browse and use. See here: https://yalis.fr/git/

When I setup gitolite on my server for Git access through SSH, of course I did test that cloning worked from outside my network. That was for my Paperweb project.
Later I configured port-knocking on the server to get rid of bot-based authentication attempts that were polluting my log files. Unfortunately, at this time, the “outside” server on which I have an account was down, so I could not leave my network to check that all was fine; from the inside of the network, all worked like a charm, though!
Same situation when someone asked me for the Paperweb code by e-mail because they could not get it the normal Git way. I had no idea that port-knocking was the problem: from my side of the firewall, all worked correctly…

Three years ago, I wrote a small series about having all my favourite tools on a USB flash drive when I am on the go. Some things have changed in these years, so the time has come to write fresh blog posts on the subject. My main aim is a full portable Linux OS, and this third part is about just that!

The following text is the second part of a reboot —as they say for films, now— of my 3-year-old series about having a universal Linux and Windows toolbox on a bootable USB flash drive. The main target is a full portable Linux OS, but I will also
address the Windows OS, for those times when you have no choice ;-)
This part is about the boot loader and miscellaneous tools accessible from there.

This is a new take on my 3-year-old series on the same subject, with the aim of having a portable toolbox for anything PC, from booting Linux, to having my favourite productivity tools at all time, to being able to rescue a broken disk or OS, and so on. This toolbox takes the form of a standard USB flash drive, made bootable and filled with all that I need, yet still uncluttered, and usable as any USB flash drive for transferring data.
This first article is about the “bootable” part.

I tried to import an old e-mail file from year 2000 or so, using Thunderbird’s ImportExportTools extension. And it failed. I first tried to split the mbox file, but eventually I found that X-Mozilla… headers were at fault! So, the solution is simply to run this command on the file before importing it in Thunderbird:
sed -i.bak '/^X-Mozilla/d' MboxFile
In case someone is interested, here is how I could split the mbox file into multiple eml files:
mkdir files.eml
awk '
BEGIN {f=0; o=""}
function new() {if (f!=0) close(o); f=f+1; o=sprintf("files.eml/%d.eml",f)}
/^From - / {new(); next}
/^X-Mozilla/ {next}
{print >>o}
END {new()}' MboxFile
This worked because each e-mail in my mbox file started with a « From - … » line. I’m not sure this is a universal rule, however.

Le Fairphone 2 est un excellent téléphone. Je ne savais trop comment présenter cette acquisition…
Quelqu’un l’a déjà fait, bien mieux que je ne saurais le faire. Allez-y, c’est très bien écrit :

Heureux possesseur d’une théière électrique riviera&bar Yunnan, je déplorais toutefois le volume strident de son alarme sonore, dont le rôle est d’informer l’utilisateur des différentes étapes : ébullition, infusion, maintien au chaud… Il suffit d’ailleurs de consulter la FAQ du fabriquant concernant cette théière pour s’en convaincre ; une seule question à ce jour : « Peut-on retirer les signaux sonores du produit ? »
C’était insupportable ; j’ai donc atténué le volume sonore de son « buzzer ».

A bit more than a year ago, I hardened my SSH server, which resulted in the near-disappearance of automated SSH login attempts. Alas, the script-kiddie tools have finally caught up with the current state of cryptography; or at least with the level of cryptography that I dare require, and still maintain compatibility with most devices that I use.
Fail2ban, although dormant all this time, still ran like the ever-vigilant Argos, and resumed its usual work as the attacks came back. But I do not like relying solely on fail2ban. So I decided to add port-knocking as a protection.

My ageing eSATA SheevaPlug is running a lot of tasks:
It is now running Debian Jessie, after having run Lenny, and then Wheezy, which shows just how long it’s been running, considering the long lifetime of a major Debian version :-D
With only a half-GB of RAM, it’s come to the point where swap is being used on a regular basis, although not too much so far. As for the processing power, everything works, albeit slowly; reasonably so… so far. And more importantly, anything more is impossible (eg. nice ownCloud modules, or a sound server…).
The time has come to plan a replacement, which is the subject of this post.

I am very fortunate that one jflesch on GitHub decided one day to create Paperwork! This excellent program evolved very quickly and is still improving. I manage all my official documents, invoices, and such, in Paperwork. Scan by scan, PDF import by PDF import, I am slowly approaching the 2000 documents, or 5000 pages. This program has proved invaluable in the past year alone, both for speeding up the processing of new documents, and for looking for old documents.
Yet I miss one feature: the possibility to search the database of documents (which is on my home server) from any computer or mobile device, without having to launch Paperwork, which is only installed on the main family PC.
Besides, as I often connect to my server from distant places using OpenSSH, the possibility to do command-line searches would be a big improvement over my current use of find, grep, etc. Or I should rather say, my former use of find, grep, etc. Because…

Like everyone, I have important data on my computer. Like everyone, I have a backup (several, actually) of this important data —you do too, don’t you?— But while this backup is good enough in case I have a hardware failure, it won’t help me if my apartment gets flooded or catches fire. That’s because the data and its backup are stored in the same place. Several solutions exist.

J’ai recommencé à tenir mes comptes dans l’excellent GnuCash. Comme je n’ai pas le temps (ni l’envie) de tout saisir pour ensuite rapprocher les comptes, j’importe les données depuis les fichiers téléchargés sur Internet et je me contente d’affecter les revenus et dépenses, et vérifier que tout est normal.
Mais tous les organismes ne fournissent pas de fichiers directement exploitables. Beaucoup se contentent de fichiers PDF…
