Submission + - Ripping the water

VincenzoRomano writes: "The American Insitute of Physics is proving details about an interesting experiment where two scientists prove you can actually rip a fluid (well, not actually water but an undrinkable mixture of water, soap, and certain salts).
The result is that if you drag a cylinder fast enough, the fluid gets ripped into several parts, with separate surfaces, which take as long as a few hours to close up.
Nice photos of the experiment are provided for the sake of curiosity."
United States

Submission + - Anti-science people cannot use technology?

VincenzoRomano writes: I'm wondering whether the low and slow penetration of technology in the USA can be explained with anti-science behaviours and beliefs like creationism.
To cut short a quite longer story, almost all current technology has been thought, designed and built thanks to the Science and its scientifc method.
If you refuse the latter, maybe, you are not willing nor can use the former. Unless you are going to selectively negate the science, which in my opinion makes even less sense.
Are the USA headed towards a technology regression era?
What'd be the Slashdotters opinion?

Submission + - Google Mail can be down up to a whole working day!

VincenzoRomano writes: "While browsing one of the Google Apps pages I have found that they guarantee

99.9% uptime for email

Unless maths is an opinion, this yelds to a yearly downtime for about 8 hours and 45 minutes a year. Which in turn becomes 1 working day from the end user perspective. With no service and possible lost emails.
While this could make sense for a small ISP, it doesn't for such a giant, even if they (almost) clearly and unanbiguously state it.
So either this is a typo or an outdated piece of information, or they seriously think that GMail can stay down that long and still be an acceptable service level agreement.

For the sake of completeness, 99.99% uptime equals to little more than 52 minutes a year with no service and 99.999% uptime gives you a maximum of 5 minutes and 15 seconds of unavailability in a year."
Operating Systems

Submission + - Where are Linux Distros headed to?

VincenzoRomano writes: Nowadays we can choose among dozens of active distributions, at least three or four desktop environments, half a dozen of web browsers and office suits.
Every single choice can show its own pitfalls resulting in a incomplete hardware support or even in unstable or unmaintainable installation.
More sadly, almost all distribution teams moan about the lack of resources, both human and economic.
This is clearly due to the fragmentation. Such a thing doesn't seem to happen for *BSD systems where the choice can be done on the fingers of one hand.
Wouldn't you promote some kind of consolidation in the distribution arean for the sake of stability and in order to have a better use of the available resources for a better Linux?

Submission + - What's the best Linux Distro/Laptop pair?

VincenzoRomano writes: "It's now a year I'm running Linux KUbunbtu on my ASUS V6J Laptop. Almost happily.
In a near future I will need to buy one more laptop for my employee (aye, I have one!) and I'd like to know more about the Slashdot community experience.
What I have in mind is to have as much hardware as possible working under Linux, especially the modem and the irda (if present) as well as all other "basic" hardware, like wired/wireless interfaces and graphics card.
I have no special requirement for the Linux distro, as my personal experience is limited to (in time order) Slackware, Gentoo and KUbuntu. The activities to be carried out are somewhat in between "personal productivity" and "application development", as the guy will travel a lot and will run GCC compilers, PostgreSQL DB and Apache.
What'd be your choice?"

Submission + - Fair manufacturer's technical support

VincenzoRomano writes: One year ago I decided to buy some "enterprise grade" hardware, firewalls actually, in order to replace the old ones used by the former ISP.
Before buying them I did a kind of survey. I browsed the product "data sheets" from the manufacturer web sites and in some cases, asked for more details by email.
I finally choose a top product already in the market since one year and a half from a very well known and reputable company.
The product showed a nuber of issues as soon as unpacked and put to work. I mean things like not being able to keep a VPN up and running for more than a bunch of minutes or doing bad IP routing on the LAN.
I've spent the last year to make that equipment working accordingly to both their data sheets and the features expected from an "enterprise grade" product.
Important issues are still open while the technical support is actually relying on my own stuff and setup and on my personal availability in order to do troubleshooting, firmware beta testing and other experiments.
I've finally blamed the product as

"far from being ready to market or even usable for beta testers"
and have requested some kind of compensation for all the job I had to do.
What's your opinion about such a behaviour in a company? Is it fair?

Submission + - Is it fair to help manufacturers debug products?

VincenzoRomano writes: It's a common use for manufacturers to put products on the market that are not completely and fully working.
Then they rely on users' feedbacks and often support in order to debug, trobleshoot and fix the products.
My main focus is on professional and business networking products, but I think this applies to other kind of products.
Sometimes those troubles are quite specific and rare. But more and more often the products are delivered as barely working or even not working at all, even on the very basic features.
In other words, products can be delivered with little or no QA at all.
I think this is not fair, especially when they ask you to collaborate (for free of course) to troubleshoot the problems.
I'd lke to pay, say, 50% at the buy and 50% when the product is fully working. Or define a hourly wage for the time I spend for them.
What'd be your opinion and experience?
Should we ask for some kind of reimbursement?

Math

Submission + - Mathematical Lego (R)

VincenzoRomano writes: "Almost everyone knows about the numerous applications and use for the ubiquitous LEGO(R) toys.
Anrew Lipson has built a web page in his site about Mathematical LEGO(R) Sculptures he made, even if he admits they weren't constructed entirely without computer assistance.
Those sculptures are also documented with photos and Lego Draw and CAD .DAT files.
By the way, I'd suggest you to check whether your children are already building such things out of Lego bricks."

Submission + - PostgreSQL 8.2 Enters Beta

VincenzoRomano writes: "PostgreSQL, the highly scalable, SQL compliant, open source object-relational database management system, is now undergoing beta testing of the next version of the software: PostgreSQL 8.2.
Of course, while "the feature freeze for version 8.2 took place on August 1st, 2006" there is still no reliable forecast for the final release date.
This new version should show, among all others news, performance and query language ebhancements and various improvements. There is a detailed report on this.
All people willing to help is invited to participate!"
Security

Submission + - Illegal wiretapping and Telecom security

VincenzoRomano writes: "A tornado is raiding over Telecom Italia, the Italian incumbent for telecommunication services industry, both fixed and mobile.
On Sept.20 Giuliano Tavaroli, former Security Manager of Pirelli, the controlling company, has been arrested along with 20 other people, some involved in the national security agency.
The main charges are for espionage and corruption and it seems that even Marco Tronchetti Provera, president of the contrlling company, has been actiuvely involved in this scandal. Nothing really new in the industry world.
The real point is that investigations are showing how easy it can be for an unfaithful employee to get traffic details and even record wiretapped conversations from the telecom infrastructures without leaving any evidence and for very modest amounts of money.
For sure every "modern" country like Italy has a number of laws against this to happen, but what about "technical enforcements"?
