GitHub’s commitment to npm ecosystem security | The GitHub Blog – no npm package can historically ben tracked to be authentic

Posted by jpluimers on 2021/11/18

What started as [Wayback/Archive] GitHub’s commitment to npm ecosystem security | The GitHub Blog with this qoute:

on November 2 we received a report to our [Wayback/Archive] security bug bounty program of a vulnerability that would allow an attacker to publish new versions of any npm package using an account without proper authorization. …

This vulnerability existed in the npm registry beyond the timeframe for which we have telemetry to determine whether it has ever been exploited maliciously. … the timeframe for which we have available telemetry, which goes back to September 2020 …

This basically means you cannot trust the authenticity of any npm package published through the registry.

It sparked reactions like these:

GitHub – JanDerogee/TeleJukebox: A project based on the concepts of the Wonderfoon and Arduinofoon

Posted by jpluimers on 2021/11/18

[Wayback/Archive.is] GitHub – JanDerogee/TeleJukebox: A project based on the concepts of the Wonderfoon and Arduinofoon which simplfies the design of the Wonderfoon keeping the most important music playback feature down to

a simple PCB in a small case where you plug the phone in

…

The completed project works very simple:

  • Pick up the phone, you hear the “dial tone” MP3, Dial a number, you hear the MP3 0..9 playing (depending on the dialed number), When the song is over, you hear the “disconnected” MP3, You can dial another number and hear another song or hang up the phone.
  • Some phones also have a button on the front. When you press this button, the phone randomly playes one of the songe 0..9 and when that song is over, it automatically plays a new song, randomly. This will allow the person on the phone to continuously listen to the music. This may be of help to those who can’t figure out how it works but love to hear the songs over and over again.
  • You can configure the music folder from which the MP3s are played, you can use up to 10 different folders
  • You can configure the volume of the device
  • Configurations are done through the phone itself (dial 738 OR hold the button while picking up the handpiece), you hear a voice that guides you through a menu and all you need to do is dial in your settings value.

You can power this design through a USB port cable. This way the device can be fed using a simple mobilephone charger OR be connected to the PC. When connected to a PC, the TeleJukebox identifies itself like a USB-stick and you can easily modify the file without removing the card from the system. Meaning that you do no even need to open the case in order to change the collection of MP3 files. Keep in mind that when the device is in USB-stick mode, it cannot playback MP3 files meaning that in this mode it will not act like a TeleJukebox.

Music rights

Especially when using this in a professional environment. be sure the music that plays is rights free (there are music therapists for treating people with Alzheimer’s and dementia that can help you with that).

checkbashisms(1) – Linux man page

Posted by jpluimers on 2021/11/17

Even with lots of experience, one learns new things every day.

A while ago, I discovered checkbashisms which checks sh shel scripts (usually with extension .sh) scripts to they do not contain code specific to bash.

[Wayback] checkbashisms(1) – Linux man page

checkbashisms, based on one of the checks from the lintian system, performs basic checks on /bin/sh shell scripts for the possible presence of bashisms. It takes the names of the shell scripts on the command line, and outputs warnings if possible bashisms are detected.

Note that the definition of a bashism in this context roughly equates to “a shell feature that is not required to be supported by POSIX”; this means that some issues flagged may be permitted under optional sections of POSIX, such as XSI or User Portability.

In cases where POSIX and Debian Policy disagree, checkbashisms by default allows extensions permitted by Policy but may also provide options for stricter checking.

The source by now is a Perl script (it used to be a bash script) of which you can find the latest version here: [Wayback] scripts/checkbashisms.pl · master · Debian / devscripts · GitLab

Not installed by default

Virtually no distribution has checkbashisms installed by default.

In fact, the package containing checkbashisms heavily varies by distribution.

For OpenSuSE, it is in a package by itself: [Wayback] openSUSE Software: package checkbashisms

checkbashisms

Tool for Checking /bin/sh Scripts for Possible Bashisms

checkbashisms performs basic checks on /bin/sh shell scripts for the possible presence of bashisms. It takes the names of the shell scripts on the command line, and outputs warnings if possible bashisms are detected.

Interesting situation now UWP isn’t panacea any more: for Windows development, native is back to center stage

Posted by jpluimers on 2021/11/17

Summary: UWP (Universal Windows Platform) is dying, long live native Windows development.

Source: [Wayback/Archive] Native Windows is Back to Center Stage

With the downplay of UWP, native development is again the primary Windows development model, after 20 years (given we had .NET in between). Native is what Delphi does at its best, so this is great news

RedHat and Fedora Core Linux

/sbin/service sshd restart

Suse linux

/etc/rc.d/sshd restart

Debian/Ubuntu

/etc/init.d/sshd restart

Solaris 9 and below

/etc/init.d/sshd stop
/etc/init.d/sshd start

Solaris 10

svcadm disable ssh
svcadm enable ssh

AIX

stopsrc -s sshd
startsrc -s sshd

HP-UX

/sbin/init.d/secsh stop
/sbin/init.d/secsh start

Note that for opensuse, by now you need this to restart sshd:

/usr/sbin/rcsshd restart

Need to check if “PrivacyNator” is already out: a local TensorFlowJS app that blurs your screen when you are not behind it

Posted by jpluimers on 2021/11/16

Interesting app that hopefully does get published: “PrivacyNator”.

So I need to check if anything new has turned up on [Wayback] “PrivacyNator” – Google Search.

The horrors of HTML email where there CSS

Posted by jpluimers on 2021/11/16

[Archive.is] Kat Maddox on Twitter: “Who’s the CEO of emails I need to talk to him… “:

This is why dreamweaver still exists.

[Archive.is] Kat Maddox on Twitter: “You don’t need a time machine to go back to the past. You just need to try to write HTML in emails. If I have to nest one more table, I’ll have gone back far enough to be able to warn people about the dot com bubble. Fuck it. I’m writing this newsletter in markdown”

Markdown with an HTML generator actually is quite a good way to get HTML emails going.

Another route is [Wayback] Foundation for Emails | A Responsive Email Framework from ZURB.

Oh remember this: [Archive.is] StuAngel on Twitter: “rule of thumb “the mail clients are about 5 years behind in HTML support” – that was like 10 years ago and they have never gotten any better… https://t.co/lVAW5YCubm”

unix/linux: using paste to turn separate lines into a comma separated list

Posted by jpluimers on 2021/11/16

Never to old to learn new things: I was totally unaware of the GNU paste tool that is available on virtually all unix/Linux/BSD core installs.

Thanks [WayBack] zeppelin for answering this question at [WayBack] linux – Turning separate lines into a comma separated list with quoted entries – Unix & Linux Stack Exchange:

You can add quotes with sed and then merge lines with paste, like that:

sed 's/^\|$/"/g'|paste -sd, -

If you are running a GNU coreutils based system (i.e. Linux), you can omit the trailing '-'.

If you input data has DOS-style line endings (as @phk suggested), you can modify the command as follows:

sed 's/\r//;s/^\|$/"/g'|paste -sd, -

Now I can get a comma separated list of for instance ssh available mac algorithms:

# ssh -Q mac | paste -sd, -
hmac-sha1,hmac-sha1-96,hmac-sha2-256,hmac-sha2-512,hmac-md5,hmac-md5-96,umac-64@openssh.com,umac-128@openssh.com,hmac-sha1-etm@openssh.com,hmac-sha1-96-etm@openssh.com,hmac-sha2-256-etm@openssh.com,hmac-sha2-512-etm@openssh.com,hmac-md5-etm@openssh.com,hmac-md5-96-etm@openssh.com,umac-64-etm@openssh.com,umac-128-etm@openssh.com

Robotkots.nl: Deny-list and settings Dutch CoronaCheck Covid-19 QR code status app (by Joost Schellevis: @Schellevis)

Posted by jpluimers on 2021/11/15

Covid-19 QR codes blocked by the Dutch app are at [Wayback/Archive] Robotkots.nl (because QR codes are like robot vomit: [Archive] Alexander Klöpping on Twitter: “QR-codes zien eruit als robotkots. Dat is gewoon een feit.”)

This site used to be [Wayback] ctb.schellevis.net but has been redirected to Robotkots.nl for about a week.

Older versions of this site referred to the tests and vaccins by their code names, but now it uses more readable names, so I made a translation table:

[W/A] links Code name -> “Readable” name
[Wayback/Archive] LP217198-3 -> antigeen
[Wayback/Archive] LP6464-4 -> PCR
[Wayback/Archive] EU/1/20/1528 -> Comirnaty (BioNTech/Pfizer)
[Wayback/Archive] EU/1/20/1507 -> Spikevax (Moderna)
[Wayback/Archive] Vaxzevria (AstraZeneca)
[Wayback/Archive] EU/1/20/1525 -> Janssen
[Wayback/Archive] Covishield (Indiase versie Vaxzevria)
[Wayback/Archive] BBIBP-CorV -> BIBP (Sinopharm)
[Wayback/Archive] CoronaVac -> CoronaVac
[Wayback/Archive] Covaxin -> Covaxin
