Using "At" to schedule Linux jobs, thanks to: Job scheduling with cron and at

There is lots out there about cron, but I like this explanation of "at", and sometimes it's what you need (esp. if your cron is temporarily hosed):

Listing 5. Using the at command
[ian@lyrebird ~]$ at -f mycrontest.sh -v 10:25
Sat Jul  7 10:25:00 2007

job 5 at Sat Jul  7 10:25:00 2007


Listing 6. Job output from at
From ian@lyrebird.raleigh.ibm.com  Sat Jul  7 10:25:00 2007
Date: Sat, 7 Jul 2007 10:25:00 -0400
From: Ian Shields 
Subject: Output from your job        5
To: ian@lyrebird.raleigh.ibm.com

It is now 10:25:00 on Saturday


Time specifications can be quite complex. Listing 7 shows a few examples. See the man page for at or the file /usr/share/doc/at/timespec or a file such as /usr/share/doc/at-3.1.10/timespec, where 3.1.10 in this example is the version of theat package.

Listing 7. Time values with the at command
[ian@lyrebird ~]$ at -f mycrontest.sh  10pm tomorrow
job 14 at Sun Jul  8 22:00:00 2007
[ian@lyrebird ~]$ at -f mycrontest.sh 2:00 tuesday
job 15 at Tue Jul 10 02:00:00 2007
[ian@lyrebird ~]$ at -f mycrontest.sh 2:00 july 11
job 16 at Wed Jul 11 02:00:00 2007
[ian@lyrebird ~]$ at -f mycrontest.sh 2:00 next week
job 17 at Sat Jul 14 02:00:00 2007

Being nice

The nice value for a job is a measure of how nice it is to other users. See our tutorial LPI exam 101 prep: GNU and UNIX commands for information on the niceand renice commands.
The at command also has a -q option. Increasing the queue increases the nice value for the job. There is also a batchcommand, which is similar to the at command except that jobs are run only when the system load is low enough. See the man pages for more details on these features.

...
Listing 11. Displaying and removing jobs with atq and atrm
[ian@lyrebird ~]$ atq
16      Wed Jul 11 02:00:00 2007 a ian
17      Sat Jul 14 02:00:00 2007 a ian
14      Sun Jul  8 22:00:00 2007 a ian
15      Tue Jul 10 02:00:00 2007 a ian
[ian@lyrebird ~]$ atrm 16 14 15

High Functioning Autism & College - The Experiment - thanks to The memories of a Product Manager

I like a number of the posts on this blog, esp. about High Performance Computing/High Throughput Computing.
But this article?  It also makes me wonder if I know any other HFAs?...
Connie "Part of the 2-Engineering Parents Experiment" O'Dell


This blog entry is a follow up to the many articles  in this blog about Highly Functional Autistic (HFA) employment and the project Dandelion.  See Silicon Valley and Autism. A creative approach. and Outsourcing to the Autistic Rather Than to India

 Ahronovitz eyes robotic future - Rocklin  from August 2012, mentioned that David,  my HFA son and  a Whitney High grad will attend Sierra College's Mechatronics Program. He did attend the mainstream classes of professor Steven Gillette.

In December 2012, he did not pass the final exam. We treat this first semester as an experiment. The definition of an experiment, according to Wikipedia
An experiment is a methodical procedure carried out with the goal of verifying, falsifying, or establishing the validity of a hypothesis. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. 
The experiment proved that without any special assistance, most HFAs can not graduate from college. The famous myth of "Einstein was Genius with a delay development"  is not proven by facts. Just read the Einstein Biography by Walter Isaacson . The great majority of HFAs are not geniuses, as the great majority of mainstream people are not geniuses either.

Professor Steven Gillette keen and sensitive spirit of observation
“David clearly has intellectual and social abilities that lend themselves to academic and to employment opportunities. He displayed a strong desire to work independently, particularly with the programming. He was able to work with other students, and seemed to enjoy his interactions with them. I believe that David can succeed in academic and technology endeavors, with sufficient levels of support. Academically, that support must provide him with focus on timely submittal of labs and quizzes. I found I had to directly request his lab reports and quizzes. Without direct oversight he did not submit the assignments required by the class.
There is only one problem: Shadows (1x1) support for HFAs are not available  (yet) in colleges. As a national premiere , Alta California approved the funding for a student to work with David as a shadow when he repeats the same class in the first half of 2013.
A Mechatronics Lab
The Mechatronics course is not easy. Just browse through the textbook Industrial Automated Systems: Instrumentation and Motion Control  at Amazon.The course is in a lab, with specialized equipment costing perhaps as much as $100,000. The graduates from this class will have special set of skills that will make them employable for life. Automated and computerized systems are everywhere.

Most great discoveries start with failed experiments. So we start now phase 2 of the experiment.  A success here will be huge. We will learn what additional services are needed to educate HFAs in mainstream colleges together withmainstream students to acquire for life employable skills in great demand.  The next step will be to create a pilot program and get funded for five to ten HFAs students - which we identify as suitable for Robotics classes.

This is the main difference between project Dandelion, and other similar projects, like Specialisterne from Denmark: the Danish organization wants to train directly the HFA candidates for employment. This does not scale, the payoff is very slow.

We want to create an easy to scale solution, whereby we enable the Colleges and Universities in the United States and Canada, -  among the finest in the world. - to prepare HFAs people to get skilled jobs, just like anybody else.

How? I hope our experiment will give us more answers, as we pivot towards a solution

How many cron jobs are too many? - thanks to Server Fault

I liked all the answers to the question, but since the context of a hard number has come up, I have favored the answers that involved hard numbers...  Cheers, Connie

Just searching through our production systems, the largest one had 862 cron jobs (across all users, the largest single one, root, is 117), and it doesn't particularly break out in a sweat with that many.
If you start 60 jobs every minute, 24x7, and they all take two seconds to complete, then you'll probably end up in a world of pain. But, as long as the workload balances out (with quiet times and such), it should recover. Keep an eye on system loads during the peak times (CPU%, disk I/O, ...) and worry more about that than the number of actual jobs.
This question is akin to "How many processes can I run before getting into trouble?". The best bet is to try it, since it depends on your system. Cron itself has few limitations that I've found but, if you're trying to schedule tens of thousands of jobs, you're putting more of a strain on it than I ever had.
Measure, don't guess!

Cron itself will essentially never start to struggle; the system will be completely bogged down with workload long before that happens.

Do you have time to be a mentor? - courtesy of Ask Annie



Do you have time to be a mentor?

January 31, 2013: 12:07 PM ET

Some managers who have squeezed mentoring into their already-packed schedules say they get as much out of it as mentees do.Business assistance --- Image by © Laughing Stock/Corbis

FORTUNE -- Dear Annie: I am a team leader at a company that has started encouraging everyone at my level to mentor at least one or two people below us. The point is to identify those with the potential to move up and guide them toward getting the right skills and experience. We can choose our own mentees, rather than having them assigned to us, but we do have to report periodically on how it's going. In fact, "talent development" is now a big chunk of what determines our bonuses.
All well and good, but I'm so busy already that I really worry about whether I have the time to do this on top of everything else. It might help if there were some specific benchmarks for what mentors are supposed to do, exactly, but that's being left up to us, too. Can I be any good at this in, say, 30 minutes a week? Do you or your readers have any suggestions for me? — Overbooked
Dear O.: Your employer's mentoring push sounds unusually vague, but maybe that's a good thing. After all, if there are no benchmarks, you can't be accused of not sticking to them. On the other hand, the lack of specific expectations may be adding to your anxiety about whether you have time for this -- which, by the way, is far from unusual. Notes Beth N. Carvin, whose human resources consulting firm Nobscot designs formal mentoring programs for big companies, "It's very common for people's first reaction to be 'I don't have the time' when they're asked to be mentors."
And no wonder. Bill Rosenthal, CEO of communications coaching company Communispond, says that the most effective mentors do all or most of the things on this checklist:
  • Keep mentees current on what's happening in the company and in its competitive environment;
  • Participate in mentees' performance reviews "or at least provide input";
  • Showcase the mentee's accomplishments to higher-ups;
  • Help promising mentees consider "all the available development opportunities in the company, like job rotation, work on cross-functional teams, stretch assignments, and so on";
  • Arrange for help to plug any skills gaps, including training from in-house or outside sources; and
  • Step in to mediate when there's a problem -- "when, for example, there's a conflict when a fast-tracked mentee is reporting to an executive who'd prefer a more experienced person in the job."
It's a lot to take on, but according to Rosenthal, much of it can be done in "small bits of time" that fit in around your current schedule. "You can be highly successful at this by having frequent and focused meetings, or even phone calls" with your mentee, he says. It takes practice, but the experience may make you a better all-around team leader. "Mentoring or coaching people is really just a more concentrated form of what good managers do anyway."
Something else that might make the task seem less daunting is that "for a mentoring relationship to work, it has to be reciprocal," Rosenthal observes. The person you're mentoring has to do at least half the work" of nurturing his or her own career.
Moreover, Nobscot's Carvin says that, in interviews with mentors at her client companies, many initially reluctant mentors express surprise at how much they end up getting from the deal. "Working with a mentee lets you see business issues through a different lens," Carvin says. "If you're mentoring someone in a different part of the company, it gives you another pair of eyes there, which can give you information that helps you succeed at your own job. A mentee's point of view can sometimes help you understand your own team's concerns, too."
Another thought, particularly relevant since you're allowed to choose your own mentees: Carvin's firm two years ago launched a Mentor of the Year contest, wherein the nominees are selected by their proteges. The 2012 winner, Samantha Stovall, is a program manager in United Technologies' (UTX) aerospace systems division. Stovall says she learns as much from her mentees as they learn from her, but "the chemistry has to be right. It just isn't there in all mentorships. If it doesn't click, find someone it does click with."
Good luck!
