Re:It's All About Time – Remote timing attacks in PHP on Saturday November 29, 2014 @05:21AM (#8673509)
How can you actually make sensitive operations take constant time? This sounds impossibly hard. For example, your operating system could be context switching thousands of times per second. Your password comparison function could cause a page fault because the trailing end of the password spans onto another page of virtual memory. These are all factors that would throw any calculation for constant time out of the window.

He did spell organisation correctly, just used British rather than of American English.
Re:Show HN: Visualizing the Utilization of ALOHAnet on Tuesday November 18, 2014 @03:51PM (#8626265)
A small webpage I put together using JavaScript and Chart.js to help show the difference in utilization that can be achieved between slotted and unslotted ALOHAnet.

Can you not have end to end encryption of the frames that go over the wire? I guess it's immensely expensive when you're transmitting at 100Gb/s.

Oh wow. These were installed on all the computers at school. We would often have hours where we didn't have any lessons scheduled, but couldn't play games, watch YouTube or go on Facebook as we would get our accounts suspended. This was the only game we could play as we could argue that it was technically "learning". The other one was a website where you had to name and locate all states in the USA. We are a British school.

British Airways does offer quite a competitive service. Now that Willie Walsh has stopped IAG bleeding cash from the acquisition of Iberia (an airline desperately in debt) they're turning a healthy profit for an airline - a complete parallel universe to what is happening at AA.
Hi, thanks for your comments. You can type help to see a list of commands that are support.

To answer your question about cd, mv, nano, etc I made this in the few hours I had yesterday afternoon, so I'm afraid I only had time to implement a small subset of commands.

I've now put it up on GitHub (https://github.com/grbsn/web-sh). I hope people can use it as a starting point to build their own web based console applications. Let's see how it goes!

Nope. I'm actually looking at second hand ThinkPads, T series.

Ask HN: Cheap and Cheerful Laptop for BSD/Linux: what are my options?

In the title. I have a 11" 2011 MacBook Air (which I feel is one of my best consumer decisions to date, and isn't going anywhere) but I'm looking to purchase a cheap laptop that I can just run into the ground. It should be compatible with Linux/BSD out of the box. That means integrated graphics and solid network interface cards. What are my options?Edit: Battery life is not an issue. I am...

We're getting hooked up at home with FTTP this month with Gigaclear. Up to 1000Mbps symmetric up and down.

I am an undergraduate student in my final year at university. I am undertaking a dissertation to look at developing an open source web analytics package for large scale websites.

I want to understand how individuals, companies and organisations feel about their web analytics software, the security and privacy of the data collected through web analytics and if their is a demand for an open source web analytics designed for large scale websites, such as the BBC, Reuters, Hacker News, etc.

Thank you for your time!

Using your computer as little as possible?

I assume that most readers on Hacker News spent most of their daylight hours (at least Monday to Friday) in front of a computer. Do you try to avoid using your computer outside of working hours, and if so, how do you prevent yourself from wasting hours on Facebook/Twitter/HackerNews/YouTube etc..

Re:PHP is as secure as any other major language on Friday January 03, 2014 @10:49AM (#7005977)
I am confused as to whether this article is trying to compare the security of the language implementations (PHP Interpreter, JVM, Ruby Interpreter, V8) or what vulnerabilities can be exposed in programs written in the language (SQL injection, non thread safe, stack overflows) etc.
