Windows 8 Defeats 85% of Malware Detected In the Past 6 Months

ydrol Re:No platform is 100 percent secure? (299 comments)

Also Linux security is traditionally viewed from the ability to infect system files on a mult-user machine, and it had long had a superior security model in this respect.
But todays users, really only cares about their own files , which are far more accessible to malware whilst surfing the net.

Yup and male lions kill rival cubs. Foxes can rip heads off all chickens in a coop and leave bodies exposed. I'm sure certain monkeys do "bad stuff" too.

Ask Slashdot: How To Shop For a Laptop?

ydrol What will it be used for - Office & email or m (732 comments)

When it comes to PCs/laptops , Most non-tech people budget too high for their actual usage. Probably because they've just looked at the high-ticket items in the bricks'n'mortar shops. Although h264 decoding does require a bit of grunt or good gpu.

Munich Has Saved €4M So Far After Switch To Linux

ydrol Zero migration / retraining costs? (370 comments)

€2.8m licensing+€1.2hardware =€4m. So no retraining costs migrating to Linux then?

I run Linux Mint at home & cygwin is a permanent fixture in my windows work machines, just in case anyone wondered about my motives.

Bing Now Nearly As Good As Google — Says Microsoft

ydrol No comparison for specialised searching... (405 comments)

I have a script that scans my media and tries to determine what movie it is based on its name by simply searching for the name in a search engine, and taking either the first imdb reference on the results page, or the most frequently occuring one.

  The idea is for users not be be forced to rename their movies but let the script harness the algorithms on the search engine to work it out.

In my testing Google beats both Bing and Yahoo easily for accuracy of searching and has less false positives. However too many automated searches will quickly lock out the IP address on Google. So now I search both Bing and Yahoo at the same time. If they disgree on the imdb reference, only then I search Google, to cast the deciding vote. This gives very accurate results, but not much more than if I could use Google alone.

Yahoo is behind Bing for accuracy in my testing. I though Yahoo signed a deal with Microsoft and were going to start using Bing 'technology' at some point. When they do my current method will become redundant.

Should servers trust servers

ydrol Re:Answers (2 comments)

Thanks for observation re MITM - I just came across this too http://www.renesys.com/tech/presentations/pdf/blackhat-09.pdf

A lot of external vendors have to have signed certs because they have end users with browsers the get regular certificate updates.
I just though it a pain for servers that are sitting behind default deny firewalls and do not get certificate updates (esp to numerous JRE's installed on them).
But the above link with BGP hijacking, has made me think twice...

UK To Dim Highway Lights To Save Money

> That might be true when entering a well lit area, but upon leaving it, you will see much less until your eyes adapt.

Apparently this is the reason passenger aircraft dim the lights at night during take-off and landing. Should their be an emergency that causes loss of lighting they want to make sure people can more quickly acclimatise to the darkness,

Challenging software development

ydrol ydrol writes  |  about a year and a half ago

ydrol (626558) writes "How do developers progress from fairly simple integration work — eg moving and manipulating data from one system to another in a typical corporate environment — to more challenging algorithm development. Over the years I've done the former, and the challenge was usually due to time , money or resources but the actual problem space was algorithmically simple — move data from here to there — reliably. How do people get out of that environment to work on more innovative things like the Google car etc. Has anyone progressed from a corporate integration programming environment to a more R&D based environment in their mid 40s? Whats it like? I'd like to think I would have excelled in my youth with less real world distractions, but not so sure now after years of 'dumbed-down' development."

Should servers trust servers

ydrol ydrol writes  |  more than 2 years ago

ydrol (626558) writes "I'm fed up with integrations breaking when endpoints change their SSL certificates. I understand end users needing the "trust" aspect of SSL, but I see most of the time integrations between servers in the enterprise estate just care about encryption and trust is an annoyance.
(Obviously in some Sectors this might be unthinkable to ignore SSL "trust" in server to server communication, but in many its not important, is it?)

In the enterprise trust often comes through firewall default deny rules , and only allowing specific IP addresses.
And a lot of man-hours are wasted when some cloud service decides to suddenly change their root certificate supplier.

So is it OK for servers (not users) to implicitly trust servers when it comes to SSL?

Also MITM attacks are kinda hard these days between fixed IP addresses aren't they?"

Which open source video apps use SMP effectively?

ydrol ydrol writes  |  about 6 years ago

ydrol (626558) writes "After building my new Core 2 Quad Q6600 pc, I was readly to unleash video conversion activity the likes of which I had never seen before. However I was disappointed to see a lot of the conversion tools either dont use SMP at all, or do not balance the workload evenly across processors, or require ugly hacks to use SMP (eg invoking distributed encoding options). I get the impression that Open Source projects are a bit slow on the uptake here? Which Open Source video conversion apps take full native advantage of SMP?

And before you ask, no I dont want to pick up the code and add SMP support myself, thanks."

Benefits of "strict" touch typing

ydrol ydrol writes  |  more than 6 years ago

ydrol (626558) writes "Probably like most /.ers I type with most of my fingers and can get round 50 words a minute at full tilt.
Recently I've started my 4th attempt to learn to touch type (not by using tutor programs but just doing it), I'd given up before out of sheer frustration, but this time is a lot better — probably because I'm using a decent ergonomic keyboard. (bought to alleviate hand strain)
I'm at around 30 wpm and climbing. It is frustrating knowing I can type faster with my old 'style' but I hope to start hitting 70-80wpm one day.
I just wanted to ask — is it possible to type technical documents, code etc (with lots of weird characters) and still come out significantly better than my home-brew 50wpm typing style. Should I persevere?
I have noticed it does help me to focus more on what I'm thinking (rather than what I'm typing). The downside is that its harder to type when I have to use crappy keyboards (which is often the case when working at client sites etc.)"

ydrol (626558) writes "Hi, I am designing a client server application for a customer and need to make a decision between two 'design patterns'. I don't have on-hand access to suitable qualified peer-review so I thought I'd ask you guys/gals.

There is one server(Solaris 10), and approx 200 clients(Windows Desktops). (In reality its likely to be 10 :) ). Every now and then,(basically when a call arrives) the server must send a very small packet of information (approx 100 bytes) to the client.

My initial design was to have each client open a listen port to recieve the information. This listen port is within a predetermined range, and when successfully opened, the port number is send to the main server process. The main server process the stores the client listen port, IP address and username for reference, when it needs to send the packet.

Another approach, pointed out, is to simply use permanently connected sockets. I personally don't like this approach, but it does provide immediate notification when a client disconnects and makes the client code a bit simpler. However one will have to deal with TCP timeouts by sending keepalives or re-establishing the connection. But it is NAT/firewall friendly (although this is not an issue)

All of the telephony solutions I've seen use the client-listen socket approach, but they have to be able to scale to unknown numbers of clients. I expect much less than 200 clients at any one time.

Does the slashdot crowd have any thoughts, pros, cons of either approach?

e.g. Dealing with lost connections , scalability, robustness etc.

Or could anyone point me to a good reference on network design patterns?"

Presumably they dont want students stealing electronic copies of their work and traning others, as it is a lucrative source of revenue. The downside is, that it is often impracticle to refer to these traning notes after the course is over. Does anyone have any ideas — both for students (short of using psexec to grab the electronic notes from the teachers laptop ) , and for traning companies themselves on how we can improve the situation?"
