rshekhar@rshekhar$ dict hypothesis
From WordNet (r) 2.0 [wn]:
hypothesis
n 1: a proposal intended to explain certain facts or observations
2: a tentative theory about the natural world; a concept that
is not yet verified but that if true would explain certain
facts or phenomena; "a scientific hypothesis that survives
experimental testing becomes a scientific theory"; "he
proposed a fresh theory of alkalis that later was accepted
in chemical practices" [syn: {possibility}, {theory}]
Here are some of my hypotheses, tentatively named lunatech's immutable laws of life
All new PHP programmers want to write a content management system
All new Java programmers will write a chat client
All college students love complexity and will do everything to increase it (at least the amount of complexity in their lives)
All college students want to do a project in 'networking'
Yesterday Lig
and me put out the third edition of the PHPCommunity Gazette. It has some very
nice articles, do check it out. If you want to write an article for
it, drop us a mail,
but remember that we would not be able to pay you anything, except a
nice "thank you" note - it is a voluntary effort .
Some weeks back, I was talking with my manager about AI and how it
is such a bogus field. My manager replied that in a few years we will
see applications that use AI in our daily life. However, I was quite
skeptical - and I refused to agree to this. He then gave an overview
of neural net and how they can learn to solve the problems. Here I
pointed out that Bayesian filters can also be considered a form of AI,
as they can learn from their previous data and they can make
decisions, but Bayesian filtering is mathematics and not AI. At this
he replied that most of AI is mathematics and only some part of it is
hocus-pocus and hand waving.
This brings me what I have been thinking for a long time.Joel write
A very senior Microsoft developer who moved to Google
told me that Google works and thinks at a higher level of abstraction
than Microsoft. "Google uses Bayesian filtering the way Microsoft uses
the if statement," he said.
. I had always suspected
this and had also felt that this was the way to go. A few months
back, we had a presentation by a researcher (not a Yahoo! employee),
who was working on extraction and summarization of documents. He had
a formula that he was applying on the sentences of the documents to
find the weight of the whole sentence and then finally if the weight
of the sentence was above some limit, it showed up in the summary. I
was skeptical about this approach - my belief is that the Bayesian
approach can be used to classify documents. Luckily, there is a project that seems to
provide a framework on which things can be built further.
By default, MySQL's datadir is placed in the
/var/lib/mysql directory. However, if you are planning on
using MySQL tables to store a lot of data and your /var
partition is small, it might cause you problem at a later stage. In such
a scenario, it is better to move the MySQL's datadir to
another partition (like /home.
The steps are
Stop your mysql server before starting this operation
Create the directories that will be new datadir
chown the directory to the mysql:mysql
user
copy the files from the old datadir to the new
location. However, make sure that the files named
ib_arch_log_0000000000, ib_logfile0 etc. are not copied
to the newer location.
Make sure that the files and directories are owned by
mysql user
Make changes in the my.cnf to point the new
datadir.
Restart the MySQL database
You might need to do varying degree of troubleshooting to get the server
working if there is some problem
Create a new database and verify that the files for this database
are getting created in the new datadir
After the server is running for a few days properly, get rid of
the old data.
Sleep
I tested these steps on MySQL 4.0.24 and all my tables were MyISAM type.
One of the details that emerged from Curt's monitoring of the Invita
Security network involved a password used by Alexey Ivanov. When
accessing one of his drop sites, Alexey's FTP password was
www.pidor.com (Internet Archive available). Think of what an unwary
analyst might do with that information. Only someone who is monitoring
Alexey's actions might know about www.pidor.com. Say that unwary
analyst decides to visit www.pidor.com to learn more about the
site. If Alexey or a friend is monitoring Web accesses to
www.pidor.com, they could learn that they are being monitored. This
case demonstrates how important it is for analysts to not "touch"
remote or foreign sites involved in intrusions. You may tip your hand
to the attacker and ruin an investigation or recovery effort.
