I'm not an expert in the IP, but this 2021 summary is better than my best understanding https://41j.com/blog/2021/05/the-next-few-years-in-dna-sequencing/

While sulfuric or nitric acid is the best way to do this, you can also decap using a box cutter and some patience. I recently did this to figure out if an opamp I bought was fake: http://41j.com/blog/2019/03/various-op177-die-images/ I’ve posted some better images here: https://twitter.com/new299/status/1111301269988106245?s=21 I’m going to try and get setup to decap properly. But the for those more concerned about using the required acids, a box cutter can give some insight into what’s going on in many devices...

Lots of terminals support both inline and loaded graphics. A surprising number of terminals support things like OSC 1337: https://chromium.googlesource.com/apps/libapps/+/master/hterm/doc/Cont… It's worth noting that iTerm2 and ChromeOS's HTerm (https://chromium.googlesource.com/apps/libapps/+/master/hterm) are a popular but hardly singular example. The (unfortunately name conflicted) HTerm/Hackterm is a pretty cool example of an older standard: http://41j.com/hterm/

Would love to try it, but the "Linux" link points to a DEB package (I'm on RPM distro ..) that's missing (404): http://41j.com/hterm/hterm_0.0.1-1_amd64.deb Can you provide a generic binary?

MEMS microphones are fascinating, and incredibly small: https://41j.com/blog/wp-content/uploads/2016/10/chipworks_iphonememsmi…

I found your hack (http://41j.com/blog/2016/09/mirrorswitch/) very interesting. Enough to pop open a dumb switch I had laying around... RTL chipset. Googled the DS in 2 minutes. What do you know... VLANs, port mirroring, IGMP snooping, ACLs and an embedded 8051!

hterm[1] supports ReGIS which is vectors graphics. A standard xterm supports vt340 if you start it with the option "-ti vt340" which supports ReGIS as well. [1] http://41j.com/hterm/

Well there is HTerm which is available for Linux. http://41j.com/hterm/

Hm, I remembered something seemed to be linked here on HN some time ago, so after quick googling: https://news.ycombinator.com/item?id=7539648 http://41j.com/hterm/ Surprised that you missed it, so I'm still not quite sure if maybe I misunderstood something in your question, or you were just having some healthy holidays around that particular time :) [EDIT] Oh! For more added fun, I've stumbled upon ReGIS's sibling for bitmaps, SIXEL; some pretty screenshots e.g. at: http://web.archive.org/web/20140521194225/https://pypi.python.org/pypi… (submitted to the Wayback Machine, as it loads faster from there for me...)

I remember that the early comments were pretty negative on the Parallella. https://news.ycombinator.com/item?id=5557985 http://41j.com/blog/2012/10/my-take-on-the-adapteva-parallella/ How does the product rate now that it's finished? I bought one and I think it should be shipping in the next week or two. My feeling was that good or bad, supporting the Kickstarter campaign might help spur the industry just a tad bit faster. We really seemed to have stalled on multi-core general purpose computers.

Is hterm.js in any way related to http://41j.com/hterm/ ?
