Block or ignore someone – Computer – Hangouts Help

Posted by jpluimers on 2020/08/17

Blocking persons (for instance for sending you materials that in G+ would be a T.O.S. violation) is only possible by blocking them, not by reporting them.

Most hangouts users however do have a G+ account, so you can request a block there.

Twitter thread unroll so you can read tweet storm on one page without distraction: ThreadReaderApp.com a.k.a. tttthreads.comtttthreads.com

Posted by jpluimers on 2020/04/24

I am have been using ThreadReaderApp.com – and more so since G+ went belly up – but forgot to schedule a post on it, so here it is:

[WayBack] Show HN: Unroll Twitter threads for easy reading | Hacker News:

I made this new service called Thread Reader that given a first tweet from a twitter thread will return a carefully designed web page with the full [WayBack] Tweetstorm unrolled.

It comes with two “bots” – one that answer people who mention “@tttthreads unroll” replying to the first tweet of a threads and give them a link to the unrolled story – the second that search twitter for “#threads” and check if it is a valid thread (> 5 tweets) and if so post a unrolled version back to the author (limited to a few post per hour to avoid to be too spammy)

The stack is good old LAMP using the PHP silex micro framework and of course Twitter API

[WayBack] Thread Reader Thread Reader helps you discover and read the best of Twitter Threads

Binary search for finding problematic versions: install a specific version in homebrew and git bisect

Posted by jpluimers on 2020/04/14

I’ve used these excellent posts to find out which youtube-dl version started to exhibit troublesome NPO downloads, then later find the actual failing commit:

Why the effort? I needed an as recent as possible youtube-dl working on as many sites as possible because of some work preparation.

The first link is very important because brew versions and alternatives have stopped working some 6 years ago, even though they turn up high on Google searches for brew install specific version. Hence the quote from the first link:

Installing software packages on Mac is very easy with homebrew. You typically get the latest version, however often in production you do not have the latest version of a software package. Another use case is when you upgrade to the latest and you find out there is bug which blocks you doing something. In this case you would like to downgrade to the previous version until the bug is fixed.In both cases you need to install a specific version of a software package with homebrew on your Mac, which tends to be not that trivial. There is a lot of discussion about this on stackoverflow but some of them are outdated based on brew versions which is not available anymore.

Common SMTP message size limits

Posted by jpluimers on 2020/04/08

After a 2018 discussion with a “zorgkantoor” (Dutch for office that arranges for special long term health care needs, successor of AWBZ) about their very low (10 megabyte) SMTP message size limit – even though they expect scanned PDF documents.

Their web-care team posed this limit as normal, so I made a list of limits in their peer group, common world-wide and well-ranked Dutch internet providers.

My plan is to check the progression of these limits over time.

Note these are the bruto message sizes including encoded attachments. Since encoding in [WayBack] MIME Base64 – Wikipedia has a overhead of at least 37% (encoded size is at least 1.37 the original size), the unencoded maximum size is less than 73% of what is listed below.

mail.com (handled by gmx.com) can reject SMTP connections as early as in the EHLO stage

Posted by jpluimers on 2020/04/06

I found this in one of my logs a a while ago:

Error when executing EHLO command for domain mail.com on SMTP server mx00.mail.com.
(554, 'mail.com (mxgmxus007) Nemesis ESMTP Service not available\nNo SMTP service\nBad DNS PTR resource record.\nFor explanation visit http://postmaster.gmx.com/en/error-messages?ip=37.153.243.242&c=rdns')

It means that gmx.de / mail.com are among the strictest email handling providers I know. I don’t blame them: EHLO is at the start of an extended SMTP session.

At [WayBack] Error messages | GMX Postmaster it indicates:

5xy Bad DNS PTR resource record

Emails from your email server were rejected because the PTR Resource Record (PTR-RR) of your IP address does not follow our guidelines. Possible reasons for this can be:
