j_not_j··on Is systems engineering just generalist engineering?
incose.org

There is a useful (but general) definition there.

It is not wrong to be doing system engineering in a purely software context. There is more to know.

j_not_j··on Apple tracking devices being used in thefts of high-end cars
I actually had a situation where the dealer disabled the electronic keys entirely (and by accident). They had disconnected the battery for some electrical diagnosis and neglected to re-enable the locks.

When I noticed this, many days later (!), I had to take the car and both keys back for them to reprogram. I expect the car was programmed to accept the keys, and not the other way round.

j_not_j··on Movie dialogue has gotten more difficult to understand
British actors are usually better actors too.

Some US programs used British actors to "raise the game" for their US co-workers.

Examples: The Americans, The Wire, Homeland, Deadwood, etc etc.

And as a side-effect, the dialogue was generally more understandable.

j_not_j··on Ask HN: Tips on Sysadmin Job
My 32-years of experience suggests:

1. Don't do anything that you cannot undo. Like, copy the /etc/passwd before running vi on it. Or yelling at a user. Or upgrading software or operating system -- have backups.

2. Have the trust and authority of your manager. This needs to be negotiated in advance. Warn management of your steep learning curve and warn them to expect outages. Ensure you can tell users to wait because you have a priority list established with your manager. Remind users, if necessary, that they are not your manager.

3. Make a note, even if just by counting, every user request. For 100 users you might expect 50 to 200 requests per month. Be sure management sees this report. It is evidence to support additional hiring.

4. Learn customer service skills. Be able to stay completely calm in the face of the CEO screaming in your face. This requires a lot of "emotional IQ" and probably training and coaching. If you can achieve this level of zen-consciousness just 80% of the time you win.

All the other advice posted here also applies. The trick is to adapt the advice to the situation you face, and, when you make a mistake, quickly reverse course.

Good luck!

all? there are 20.

Edit: A textbook provoked the "Amazon Prime for Student" prompt. Deleted other items, and it proceeded.

After placing that order, the "deleted items" reappeared. So I placed a second order for those.

Amazon UI and txn flow is somewhat broken.
