Microsoft chooses not to support new Intel & AMD chips in Windows versions earlier than 10. The title makes it the fault of chip makers. Isn't it just a software problem?

FreeBSD took me an afternoon to set things up, but that was one afternoon in a decade.

Unbelievable, right? One could instead do a zfs snapshot and retain everything. You don't even need zfs for snapshots. UFS could do it for ages.

PLAN9 namespace is a perfect solution for this kind of package isolations. I can imagine a perfect NixOS plan9 hybrid, only if APE were good enough. Perhaps people(TM) should really pool resources together and make that happen.

It is a good form of communicating sciences. Seriously, more professors should do it as their contributions to community. Perhaps starting from more reddit AMA?

There is a note on "SMP Performance", is anyone here knows about whether and how *BSD's support the 72-core/64-core Intel Knights Landing chip? I couldn't find any relevant information via google. PS. I asked this q

Yes, you can certainly achieve that with setmode(3) and getmode(3).

I can understand that for someone has no background or long term use of chmod(1) would need some effort to decipher what 0644 actually means. However, for people who are well versed in this aspect, the numerical code is much easier to pars

With acme, most of the time I only need to 2-click any shell code that I assembled in a scratch file/window, then a new window opens with the output. We perhaps don't need smarter terminals either. Look at it in an abstract way,

Somehow we are evolving beyond the PC era by going all the way back before the PC era. The only difference: tty replaced by browsers. I get it that we need a better user interface than the plain text, but I fail to see any advantage of bro

It's a 32bit and from an old version. Perhaps they don't want to annoy their paying customers? In this way they get more information from you. I guess it's good for their marketing research. Hopefully they would conclude

The problem is that unix pipe can be blocked and you can see it as a lazy partial evaluation, so grep a HUGEFILE|head returns when 10 lines are found. In APL the semantics is not builtin, though things like ⍴↑↓ can be lazy, it's the i

For q/k in particular, you can just write a wrapper in q/k. Nothing stops you from doing while[1;0N!. 0:0] you can save the history in a table and do whatever you want.

In some way, IBM APL2 [1] was trying to achieve that with all of their APs (associated processors, APL's own way to do IPC) and built-in workspaces. You can use APL as your login shell, since it really has all the things a normal shel

Since you mentioned emacs, org-mode has the ability to attach files and show image files within the buffer, and it handles previewing latex formulas too. The problem with these kind of system is that you always need the emacs open, because

This sounds like exactly what it should be as an intro-to-* course. You are given the names and terminologies and the ability (Math! Yes, you do need it.) and freedom to explore any deeper materials on your own.

Just saw a comment in another thread, stating Apple had slipped in improving their Unix layer, and here comes this. New file system is not a joking matter: Microsoft failed to deliver their new FS; Linux took years to go from ext2 to ext3
