Why can’t you find a job with a Stanford computer science PhD?

from http://lemire.me/blog/archives/2013/09/23/why-cant-yo-find-a-job-with-a-stanford-computer-science-ph-d/

To many of my older colleagues, the idea that you possibly couldn’t find a job with a good degree, let alone a PhD, is unthinkable. And what about a promising young graduate in Computer Science from Stanford University? What if he has a PhD? He may not be able to secure an academic job, but industry recruiters will be all over him (or her). Surely!

The truth is maybe harsher.

Chand John wrote a touching article recounting his personal experience. No doubt, he expected to easily land a good industry job. At least, that is what his professors expected. Yet it took him a year to get a job. He was dismissed by most employers:

Despite having programmed computers since age 8, I was rejected from about 20 programming jobs. (…) my experience writing code at a university, even on a product with 47,000 unique downloads, didn’t count as coding “experience”.

There is a hidden assumption on campus that academic jobs are hard to get, but industry jobs are easy. Many computer science professors assume that they and their students could easily land a job at Google or any other tech company nearby. Along with this belief goes the fact that whatever happens on campus is years ahead, and much more sophisticated, than what industry does. The story goes like this: government funds professors who have the ideas, they get their students to develop these ideas… and eventually these ideas end up getting picked up by industry when students get industry jobs. The story goes back to Vannevar Bush.

There is a problem however: this story does not match the facts. Employers do not recruit graduate students to get access to the work they did on campus. When a graduate student is recruited, he will be very lucky if his new employer has more than a passing interest in what he did on campus. It is not just employer reluctance: very few students could take what they learned as a graduate student and launch a business or a consulting venture.

The truth is that if you are fresh out of school, you will be the one doing most of the learning in industry. Even someone with a PhD can expect to be an apprentice for many years.

Also, let us be honest: the software produced on campus is rarely good. It is often made of untested, undocumented, and barely functioning prototypes. I have no doubt that Chand John wrote beautiful and maintainable software while at the university. However, I understand the skepticism of employers who hear “I wrote code as a student”. It is simply not a great reference. They hear “I wrote software for fun”.

So, people like Chand John end up with prize-winning research that is of little interest to anyone in industry. They wrote code on campus, but employers think “Oh! God! They will have to unlearn everything and start from scratch”. Is it any surprise that they are not offered the top programming jobs?

Of course, it is not entirely fair to say that Chand John couldn’t easily get an industry job. He does not tell us how selective he was. I am asked routinely by people from industry about clever graduate students. Presumably, what he couldn’t get easily is an interesting job. A job that would allow him to pay his student debts and offer him an intellectual challenge.

These jobs are scarce, both in industry and in academia.

Update: It looks like Chand works for Honda Research in what must be a desirable position.

CVS server on CENTOS

leave a comment »

updated from Set Up CVS Server on Linux http://is.gd/W35qfq (some mistakes and some problems found)

Assumption: server: s.com   client: c.com
Goal: user mike can use the CVS on s.com (assumption: mike has an account as “mike” on s.com)

At the first we need to create users:

in MS Excel

useradd -c <comment> <username> -G cvs

=CONCATENATE(“useradd -c “,LOWER(LEFT(RIGHT(B7,LEN(B7)-FIND(“,”,B7)-1),1)&(LEFT(B7,FIND(“,”,B7)-1))))

change password

=CONCATENATE(“echo “,CHAR(34),LOWER(LEFT(RIGHT(B7,LEN(B7)-FIND(“,”,B7)-1),1)&(LEFT(B7,FIND(“,”,B7)-1))),”:”,E7,CHAR(34),” | chpasswd”)

++++++++++

Steps:
1. install cvs and xinetd on the server
$yum install cvs
$yum install xinetd

NOTE: check whether cvs (or xinetd) has been installed:
$rpm -qa | grep cvs

2. set up cvs group and user on the server:
$groupadd cvs
$useradd -g cvs -G cvs -d /home/cvsroot cvsroot
$passwd cvsroot # set up password for cvsroot

Add mike to the cvs group:
$usermod -G mike cvs

Check whether mike is in the cvs group:
$groups mike

3. change owner of /home/cvsroot if necessary, chmod for /home/cvsroot:
$chown -R cvsroot:cvs /home/cvsroot
$chmod -R 775 /home/cvsroot

4. initialize cvs:
(login as cvsroot)
$cd /home/cvsroot
$cvs -d /home/cvsroot init  # full path is required
$chmod 644 /home/cvsroot/CVSROOT/config

5. create file for CVS self-startup, as xinetd type
(login as root)
$cd /etc/xinetd.d
$cp cvs cvspserver
$vim cvspserver  # do the following modifications:

# default: off
# description: The CVS service can record the history of your source \
#              files. CVS stores all the versions of a file in a single \
#              file in a clever way that only stores the differences \
#              between versions.
service cvspserver
{
disable                 = no             # modify
port                       = 2401
socket_type       = stream
protocol               = tcp
wait                       = no
user                       = root
passenv               = PATH
server                   = /usr/bin/cvs
env                         = HOME=/home/cvsroot    # modify
server_args        = -f –allow-root=/home/cvsroot pserver    # modify
}

6. add CVS as a service:
$vim /etc/services

Add two lines if not in the file:
cvspserver 2401/tcp #pserver cvs service
cvspserver 2401/udp #pserver cvs service

7. restart xinetd:
$/etc/init.d/xinetd restart

8. check if cvspserver has started
$netstat -l |grep cvspserver

should return:
tcp   0    0            *:cvspserver           *:*               LISTEN

9. manage users
$cp /etc/shadow /home/cvsroot/CVSROOT/passwd   # owner of passwd should be cvsroot:cvs
($cd /home/cvsroot/CVSROOT)
$chmod 644 passwd

modify passwd, delete all lines except users cvsroot and mike (you can keep some lines if needed)
for every line, delete all the content after the second “:”, and append cvsroot to that “:”

10. on client c.com, log in to the CVS server:
$export CVSROOT=:pserver:mike@s.com:2401/home/cvsroot
$cvs login

11. on client c.com, import a project /home/mike/myproject onto CVS server:
$cd /home/mike/myproject
$cvs import -m “my project” myproject mike start

12. errors:
1) As follows:
[mike@c.com ~]$ cvs -d :pserver:mike@s.com:/home/cvsroot login
Logging in to :pserver:mike@s.com:2401/home/cvsroot
CVS password:
cvs [login aborted]: unrecognized auth response from localhost: cvs pserver: cannot open /home/cvsroot/CVSROOT/config: Permission denied

Solution: turn off SELinux on s.com.
Turn it off now:
$setenforce 0

Turn it off after next restart:
$vim /etc/selinux/config
modify SELINUX=enforcing to
SELINUX=disabled

2) As follows:
[mike@c.com ~]$ cvs login
Logging in to :pserver:mike@s.com:2401/home/cvsroot
CVS password:
cvs [login aborted]: connect to [s.com]:2401 failed: No route to host

Solution: turn off firewall on s.com, or allow 2401 port in the firewall
Turn off firewall now:
service iptables stop

Turn off firewall after next restart:
$chkconfig iptables off   # or $/sbin/chkconfig –level 2345 iptables off

Check firewall status:
$/etc/init.d/iptables status

NOTE: This method applies on Fedora 12 for CVS server

Businesses Worry About Christmas Day Attacks by By Fahmida Y. Rashid December 24, 2012 – PCMag.com

leave a comment »

“In an online survey of 270 security and IT professionals, about 57 percent said their companies may be more vulnerable to security attacks during major holidays such as Christmas or New Year’s. Breaking down by job function found that 61 percent of security professionals were concerned, compared to 54 percent of business stakeholders. The survey, which was conducted between Nov. 8 and Nov. 19, was commissioned by nCircle and conducted by Dimensional Research.” http://www.pcmag.com/article2/0,2817,2413540,00.asp
