Best IT-infrastructure For a Small Company?

RationalRoot First they need a CTO (600 comments)

How did you get hired?

Did they ask if you had experience setting up an entire IT infrastructure from scratch?

If they have hired you as a Chief Technical Officer, and you need to ask slashdot about this, then I suggest that they have hired the wrong person.

Warships May Get Lasers For Close-In Defense

RationalRoot Re:did anyone else count 15 seconds ? (482 comments)

"too late ?"

It took 15 seconds from the laser lighting up the UAV to it going down in flames.

"you'll only die wet"

Ask an astronomer about light and rain.

Your well reasoned argument is clearly more dangerous than any laser.

Warships May Get Lasers For Close-In Defense

RationalRoot did anyone else count 15 seconds ? (482 comments)

If it takes 15 seconds to knock down an unhardened target in perfect conditions, then nice science project, but you guys have still got work to do.

Off the top of my head,

a) Reflective surfaces
b) dispersing reflective particles from the aircraft as soon as a laser is detected
c) ditto, thick smoke
d) attack when it's raining

Add any of these, and it might take 1 minutes to bring down a bad guy,

How far will a missile travel in 1 minute at (how fast is a ship to ship missile any how ?)

Knuth Plans 'Earthshaking Announcement' Wednesday

RationalRoot at TeX's 32nd...... (701 comments)

Hey guess what, the announcement is at the TeX's 32nd Anniversary Celebration.

You know the Tex User Group thing.

So hands up who thinks it's likely to be related to Tex ?

So to mix my Math I suggest that
      P(Announcement(P!=NP)) ~ 0
      P(Announcement(P==NP)) ~ 0
      P(Announcement(Related to TeX)) > .5

Have we enough Ps NPs and Not reallys Ps going on here ?

UK ID Cards Could Be Upgraded To Super ID Cards

RationalRoot Cause when something goes wrong ! (197 comments)

I kind of like the idea of VISA/MasterCard/Paypal/Bank of x

They are public companies, they have a reputation to protect, people can get fired if it all hits the fan. If Visa had constantly poor security, all their customers would leave for Master Card.

If the Govt controls the payments system, and the payments systems is fragile, or easily corruptible, you can't just dump them and go to the competition.

At least in my country, govt employees pretty much need to shoot someone (during office hours, and in the office) to get fired.

Nothing good can come of this.

What Knowledge Gaps Do Self-Taught Programmers Generally Have?

RationalRoot Re:I'm Interested in the Opposite View (396 comments)

SCC and Software engineering walk hand in hand. Everything from how useful unit tests can be after merging code to how to design code so that you large teams can work on the code without stepping on each others feet.

Like chess, playing is easy. Being good takes a while.

What Knowledge Gaps Do Self-Taught Programmers Generally Have?

RationalRoot Re:I'm Interested in the Opposite View (396 comments)

1) in the real world 40% is not a pass

2) why don't many school even mention source code control?

3) error handling is not an exercise left to the reader, it needs to be structured, organised, and it really helps if you know what you are trying to achieve with the error handling.

Visualizing False Positives In Broad Screening

RationalRoot Start with the basics (365 comments)

A nurse recently told me a test was never wrong, it was 99% accurate. I asked how many people she had used the test on this week, she said about 50 a day. Without any knowledge of the population % of positives, and making the gross assumption that it was 99% false positive and 99% false negative, that would lead one to believe that she seeing incorrect results about 2-3 times a week. This had simply never occurred to her. Never mind the population statistic, nor the possible difference between false positive and false negative, but she understood 99% accurate to be - "never wrong". It never even occurred to her that if she was testing hundreds of people a week that some results would be just plain wrong. I didn't ever bother trying to explain the effect of population statistics.

Cats "Exploit" Humans By Purring

RationalRoot Cats are stupid as sheep. (503 comments)

I despise cats, I can't imagine why you cannot buy Cat Poison in the Hardware right next to Rat Poison. Yet my mother in laws cat still tries to brush up to me for food. I have never fed it, I simply push it away (Gently, my mother in law seems to be fond of it) but after many years of being pushed away it still tries. It has the learning power of a sheep.

Google Funding the Next Big One?

RationalRoot Re:Is Google EVIL now? (295 comments)

No, you all have it exactly backwards. Look at this - California is bankrupt, they're planning on paying creditors IOUs. No money. Nada. They've already asked the feds to help and Obama has said 'No'.

Don't you mean the USA is bankrupt ?

Phony Wikipedia Entry Used By Worldwide Press

RationalRoot Hand's up who is actually surprised ??? (391 comments)

I've been involved in skydiving and scuba diving for many years. Any time I have read an article about either one in the papers it is invariably inaccurate.
If they get the main thrust of the issue it's a good day.
Sure, the political reporters know about politics, and the sports reporters know about sport, but once someone has to write up a story outside his normal scope, it's as bad as any school child's homework essay.

Australian Court Lets Lawyer Serve Papers Via Facebook

RationalRoot Who would believe it. (204 comments)

Who would believe it. If I received a summons by email or on facebook (Iana Member) I would just assume it was another POS spam. I doubt I would even read it. Seriously, I'd have my solicitor show the Judge the 500+ spam messages in my spam box last week and ask him if he really expected me to be able to attach any credibility to the online summons. Then I'd show him how easy it was to make fake ones with fake from addresses and ask him again. If online summons are valid. That's a simple way around spam filters. Once someone does not get a summons because the spam filter blocks it, there will be a big fuss and spam filters will allow anything that looks like a summons. Then spam will start looking like summonses (sp?) D

Searching DNA For Relatives Raises Concerns

RationalRoot Pipes... (199 comments)

http://www.ahealthyme.com/topic/pipes
Decades ago, doctors began to notice high rates of tongue cancer in pipe smokers. Since then, pipe smoking has been shown to cause cancer of the mouth, lip, tongue, throat, larynx, and lung, Thun says. According to Thun, pipe smokers may also increase their risk of contracting other cancers that plague cigarette smokers: cancer of the pancreas, kidney, bladder, colon, and cervix as well as leukemia and diseases such as chronic obstructive lung disease, stroke, and coronary heart disease.

Ethical Killing Machines

RationalRoot War with no downside.... (785 comments)

Imagine a world where a rich powerful country can just send in the robots. It they could make war without any of their own body bags coming back, what would hold them back ? Iraq is in the headlines on a daily basis as US soldiers die. If it was only US robots being destroyed, while "natives", or "insurgents" were killed, what would press the administration to resolve the war. What I am raising is the issue of making the horrors of war one sided. If you have a peace force of robots, fine. But what about when a rich country has less noble motives. With no body bags coming home, what is to stop that country ?
