For my link archive:
These explain the below stagings.
- cT3N1Mx:
- c: stage determined before treatment
- T3: tumor invades through the muscularis propria into the pericolorectal tissues
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- Mx: could not be evaluated for distant metastasis
- cT3bN1Mx:
- c: stage determined before treatment
- T3b: 1-5 mm extension beyond muscularis propria
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- Mx: could not be evaluated for distant metastasis
- cT3N1M0:
- c: stage determined before treatment
- T3: tumor invades through the muscularis propria into the pericolorectal tissues
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- M0: no distant metastasis
- cT3bN1M0:
- c: stage determined before treatment
- T3b: 1-5 mm extension beyond muscularis propria
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- M0: no distant metastasis
- cT3bN1:
- c: stage determined before treatment
- T3b: 1-5 mm extension beyond muscularis propria
- N1: regional lymph node metastasis suspicious in 1-3 lymph nodes
- ypT2N1a:
- yp: stage determined after chemotherapy (y) and histopathologic (p), in this case also after surgeries of both tumor and metastases
- T2: size of tumor
- N1a: regional lymph node metastasis present in 1 lymph node
- No M means no metastasis detectable

For my link archive a good article and nice discussion thread:
Privacy Shield, het data-uitwisselingsverdrag tussen de EU en de VS, is van tafel. Volgens het Hof is het strijdig met de GDPR. De ‘standaard contractuele clausules’ blijven wel bestaan, maar door de surveillance in de VS wordt ook dat instrument voor de datadoorgiften een lastig verhaal.

I had this one day connecting to a guest:
debug3: send packet: type 20
debug1: SSH2_MSG_KEXINIT sent
Connection closed by 192.168.71.81 port 22
The cause was indeed a heavily overloaded box that would not respond in time to any actual data sent over network requests, but would accept the initial TCP connection.
Logging on the console also failed, but the memory and CPU usage on the wrapping host was out of the roof.
The only solution was to soft power-cycle the guest.
Very similar to:
You can also have a host who’s memory is so badly fragmented that it can’t allocate a page a contiguous memory to fork the process for hosting an SSH session.
In such a case, you can get either of the messages:
ssh_exchange_identification: read: Connection reset by peer
or:
Connection closed by aaa.bbb.ccc.ddd
depending on how far the host gets before it bails out.
If memory fragmenting is the apparent cause, the solution is to access the server via other means and to restart some of the pertinent services. I have found Apache and MySQL to be the culprit on VM’s since VM’s don’t have a swap partition. Failing that, reboot the host.

Wow: I never noticed this before, but thinking back it has happened to me at least a few times years ago: [WayBack] Windows 7 Hosts File Ignored.
The trick is to create a new hosts file as Administrator.
I thought it had to do with proper line endings: Notebad messes those up every now and then. But I was wrong: even with Notepad++ this happens, see [WayBack] I just had to trouble shoot a Windows XP (!) issue where the entries in the hosts file were being ignored. The change that actually worked was: 1. Crea… – Thomas Mueller (dummzeuch) – Google+

A few tips from posting to the openSUSE forums, learned from banging my head to the wall too often.
- They are at https://forums.opensuse.org/forum.php
- The forum software can be very slow at times taking ~tens of seconds for loading a post:
- loading multiple posts or pages of posts you are interested in multiple tabs speeds up your reading a lot
- Answers on the post often are along the form “has been answered before” without pointing to the actual link, even if the post is marked with a read icon, for instance in [WayBack] No option to “keep me logged in on this device” with Novell/openSUSE login?
- Your email is not your username, so do not use it during logon: [WayBack] Lousy log in
- The search function in the forum is horrible.
- The forum software is proprietary (vBulletin – Wikipedia) and has a
- When writing/replying to posts:
- Edit your answer off-line, because
- you will automatically be logged off even if the forum indicates you are still logged on (there is no count down of the activity timer), see
- when you re-logon, your carefully edited text has been lost from the cache
- Never use formatting, either auto-introduced, or introduced while pasting, avoid BB-code
- Reasoning
- The text-based NNTP/e-mail back-end of the forum does not support formatting well
- The HTML editor will without warning interpret all kinds of character combinations
- Those character combinations will be turned into images
- You cannot post too many images at once
- When you re-post, often your post text has been lost from the cache
- The forum editor often gets confused by formatting
- Pasting by keyboard or middle-mouse-button often includes formatting, even: [WayBack/Archive.is] forum: how do get rid of all formatting while pasting? – Page 2
- Though the forum supports BB code, NNTP news readers do not, and the added formatting gives quite a mess
- Use the text (“Source mode”) version of the editor, by first clicking the left most button: “Source”
- After this, the third and fourth button get greyed out:
- Remove formatting button is the second from the left (in both text and WYSIWIG mode): “Remove format”
- If you are in WYSIWIG mode, then always paste using the third button from the left that strips formatting: “Paste as plain text”
- NEVER EVER paste with formatting with the fourth button from the left: “Paste from Word”

Below is a cool site that I do not just list because I like the site, but also that they have a solar powered server running a low-tech version of it.
[WayBack] LOW-TECH MAGAZINE
Doubts on progress and technology
It actually started as a Dutch site, is ran by a Belgian now living in Barcelona. This means many articles are available in various languages, not just English and Dutch, but many also in French, German, Spanish, and Italian. Some articles are only available in English or Dutch.

Just in case I want to really go off-grid: [WayBack] Li-Ion BMS – Lithium-Ion Battery Management Systems and large battery packs
It has a configuration selector module pointing to companies (even one in The Netherlands) that can help me out.
Via [WayBack] DIY Electric Car Forums – View Single Post – using 18650 cells to make 25kwh battery
Hopefully they are based on 18650 batteries:

Thomas Rini (of U-Boot and Yocto fame) mentioned these solutions for remote power control of IoT devices and remote updating SD cards in this slide State of the U-Boot – Thomas Rini, Konsulko Group:
- FlashAir WiFi enabled SD cards
Two power solutions I like myself are:
The combination of these allows for really flexible production and testing environments.
