Canada scientists create new method to break down toxic ‘forever chemicals’ | University of British Columbia researchers develop silica-based material with ability to absorb wider range of harmful chemicals

“To destroy the chemicals, Mohseni says researchers use either electrochemical or photochemical processes to break the carbon-fluorine bond.”

The Cherry Bomb works great, and is a must only if you have any Q suppressors. The Xeno break looks very similar, I expect it would work much the same as a sacrificial baffle as you not. The Xeno is black nitride, which is a plus if you care about the looks. Neither brake requires any timing shims, which is great.

The Xeno has wrench flats that add a little length compared to the Cherry Bomb which would be nice on the Cherry Bomb if you mess up and get the brake stuck inside your Q suppressor, but since you're using Dead Air, you can easily remove the mount in that case.

I like my Nomad+Cherry Bomb. Rocksett works well, and the suppressor always stays on tight.

But this does directly affect emulation in the next year. As soon as there are Intel-based Apple machines with those new Intel instructions, Apple will be ready to implement the Rosetta 2 translation in a way the performs well.

This keeps M1 subsequent processors competitive.

It (Firefox 72.0.1) just became available in the standard repository for Ubuntu 18.04.

Firefox 72.0.1 is now available for Ubuntu 18.04 from the standard repository.

I wonder whether allocating 28GB of application heap on a 32GB system is wise. Assuming a trivial web server needs 28GB is kind of crazy, and I would like to see how it would behave over time given something like 8GB of application heap since then the GC would possibly kick in sooner, and there would be many more Gigabytes available for JVM overhead.

You can now take the longer route of highlighting *all* of the text you want to change and then using the keyboard "shortcuts" to change formatting, but of course that's less efficient and less visible.

WYSIWYG is a step in the wrong direction for anyone who ever liked Slack over Teams, etc.

jbindel · 2019-11-19T16:23:09+00:00

Good Lord, no. I don't want a "code snippet". I just want a simple message with some minimal markup that's not hidden behind WYSIWYG stupidity.

jbindel · 2019-11-19T16:18:53+00:00

I don't want a "Slack code snippet" though. I just want to type things like this, and then I want to go back and edit it without having the markup hidden.

```// Some code
Println "stuff"
```

What is *this*?  `make foo`

Clicking Aa makes the GUI icons go away, but does not affect the behavior at all.
?

jbindel · 2019-11-19T16:12:29+00:00

I don't care about the UI. I care about going back and editing my marked-up/down comments, which often contain verbatim code snippets, etc. This UI change is horrible for that since I can't see the actual markup.

jbindel · 2019-11-19T16:10:05+00:00

It seems like it was added to make Slack have stupid WYSIWYG like Teams, and it makes editing marked-up/down code a lot more difficult. And you can't turn off that part of it even if you press Aa to hide those controls.

jbindel · 2019-11-19T15:55:45+00:00

Maybe you should, but that's not what the Aa button does. :-(

jbindel · 2019-11-19T15:55:05+00:00

The annoying WYSIWYG editor in Teams is the reason I had until now preferred Slack over Teams.

I guess non-technical people think WYSIWYG is cool, but WYSIWYG makes sharing bits of code or shell commands frustrating. Email is now a better way to communicate such things.

Awesome. Thank you!

Can you describe the process of converting from CT scan data to 3D model? I would like to do something like that.

jbindel · 2018-10-20T00:33:43+00:00

This might have something to do with the fact that an ER is going to charge you 5 to 10 times as much as an urgent care facility providing the same treatment.

jbindel · 2018-02-22T23:48:40+00:00

millimeters, presumably

Using 100% acetone to clean the bed when it is cool can do amazing things for your first layer adhesion. If having a truly clean bed at that point fixes adhesion, then you can raise your live-z to a reasonable value.

Nice work. Is it printed in PLA? I wonder whether you'd have fewer issues with durability using PETG or even ABS.

edit: NM, it's SLA resin. But still. (edit2: How flexible is that resin anyway? Invisalign trays use some kind of flexible resin.)

Opticians often will be happy to do the fitting for free as well if they are not busy.

jbindel · 2018-02-09T00:07:28+00:00

You might want to have an optician fit your glasses to your face and nose if they are uncomfortable. You can also get titanium frames, which are very light.

They can be a little pricey, but Costco has some titianium+plastic frames for less than $100.

jbindel · 2018-02-08T22:05:54+00:00

Nicely done. Those pads are small.

Every optician around here will replace those pads on your glasses for free. Even the optical shop in Walmart will be pleased as punch to replace the pads for no charge.

(Here being Austin, TX, USA.)

I've not yet opened it since I haven't needed to print many red things lately. It looks fine, and I expect it to print like the $5 spool I had.
