Snowflake – help vulnerable people (like censored or in war zones) access the internet

Posted by jpluimers on 2022/02/28

Via [Archive] Daniël Verlaan on Twitter: “Het is lief dat mensen iets willen doen, maar dit is even “effectief” als heel vaak op je F5-knop drukken. Als je zonder technische kennis mee wil helpen, draai een Tor Snowflake zodat Oekraïners en Russen toegang blijven houden tot een vrij internet: …” / Twitter:

[Wayback/Archive] Snowflake

Snowflake is a system to defeat internet censorship. People who are censored can use Snowflake to access the internet. Their connection goes through Snowflake proxies, which are run by volunteers. For more detailed information about how Snowflake works see our [Wayback/Wayback] documentation wiki.

Run a Proxy

If your internet access is not censored, you should consider installing the Snowflake extension to help users in censored networks. There is no need to worry about which websites people are accessing through your proxy. Their visible browsing IP address will match their Tor exit node, not yours.

If you would like to run a command-line version of the Snowflake proxy on your desktop or server, see our [Wayback/Archive] community documentation for running a standalone Snowflake proxy.

Use Snowflake

If your internet access is censored, you should download [Wayback/Archive] Tor Browser.

Thinkpad max memory configurations for the models I own

Posted by jpluimers on 2022/02/28

Below are the maximum memory configurations for the Thinkpad models I own.

Note these re only 7-row keyboard configurations, the 6-row keyboards were always “meh”.

I used this command to get the CPU information:

wmic cpu get name

Memory speed

As mentioned in PC3-8500 or PC3-10600:

As PC3-10600 is getting increasingly difficult to acquire, PC3-12800 can be used instead. Using PC3-12800 may or may not increase the performance of your model, as some models may underclock it to their respective original DRAM speeds.

T510 – the midrange

Intel(R) Core(TM) i5 CPU       M 560  @ 2.67GHz

[Wayback] Category:T510 – ThinkWiki

You might think it would fit two 8GB modules and be upgradable to 16GB, but the chipset prevents it. Some of the W510 models seem to accept 8GB modules though:

W701 – the largest of the bunch

Intel(R) Core(TM) i7 CPU       Q 720  @ 1.60GHz

[Wayback] Category:W701 – ThinkWiki

  • 2, 3, 4 or 8GB PC3-8500 memory standard, upgradable to 16 GB

I actually still have 16GB in my version, see: ThinkPad W701: Win7 Ultimate x64 suddenly only saw 8GB RAM of 16GB (via: [H]ard|Forum).

Searching back my blog history, I did note that 32GB should fit: ThinkPad W701 with 32GB of memory via: • Newer 8G memory sticks in a W700, W701, W500, W510 ?

X201 – the smallest of the bunch

Intel(R) Core(TM) i7 CPU M 620 @ 2.67GHz

[Wayback] Category:X201 – ThinkWiki

Some seem to differ however, and got 16GB to work, but others don’t, as only the lower 8GB are accessible:

I might upgrade the W701, order 4*8GB modules, test some in the X201, then order more if it works.


Just in case I want to ever get a smaller Thinkpad with 7-row keyboard that allows 32-gigabytes of memory, the state as of 2019 is pretty accurate as no 7-row keyboards were manufacturerd after that (not even the horrendously expensive T25, which was a 2017 model [Wayback]/] My ThinkPad T25 review : thinkpad):

[WaybackCurrent Thinkpad models that support 32 gb ram (even unofficially) – Thinkpads Forum (state in 2019)

If you really want to go the T25 way, you can modify it to put T480 hardware in it: [Wayback] Thinkpad T25 Gets Less Retro With Hardware Swap | Hackaday

Not sure why: is missing a security certificate retraction on some Windows machines?

Posted by jpluimers on 2022/02/28

Got this on two Dutch Windows machines, not sure why yet:

Missing information on security certificate retraction

Certificate path is OK

Force downloading Windows 10 ISOs instead of Media Creation Tool

Posted by jpluimers on 2022/02/25

When downloading Windows 10 builds, I usually want them as ISO files because I test them out as Virtual Machines before running on real hardware.

Downloading can be done from [WayBack], however what you get depends on what machine you start browsing.

The above WayBack link, because it got archived from a non-Windows machine redirects from to

On Windows systems the redirect goes from to

By default, when you are on a Windows machine, the download link only provides the Media Creation tool. This forces an extra step into getting the ISO file on the virtual machine host.

When downloading from a non-Windows machine, you get a possibility to download the ISO file directly after selecting which kind of build and language you need. This provides you with a time limited https link to download the ISO (in practice this seems to last at least an hour).

I didn’t dig into this before, but luckily others did, and the difference is as easy as changing the User-Agent in your browser, as these posts describe:

Luckily, since ESXi 6.7, VMware ESXi added https as protocol to wget, so now you can download the https link you get via the above trick without hassle.

Oh, this answers my question from a few years back too: How can I get Win10_1511_1_English_x64.iso or Win10_1511_1_EnglishInternational_x64.iso ?
