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.
Just to follow up on topic of WhatsApp and Erlang, here is a presentation given at Erlang Factory 2014 about their goals with scaling WhatsApp to billions of simultaneous users.
He did spell organisation correctly, just used British rather than of American English.
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.
We're getting hooked up at home with FTTP this month with Gigaclear. Up to 1000Mbps symmetric up and down.
Are you speaking of COBOL or C++?
Birthday paradox!
Haha, I read that and thought exactly the same!
How embarrassing for OP!
How is it anything like that?
Can we see your results?
Could your performance problems be closer related to http://news.rapgenius.com/James-somers-herokus-ugly-secret-a... than the performance of Django or your code?
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!
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.
Exactly! Just because you choose to drive your car into a brick wall at 100mph, it doesn't mean your car is unsafe.
This is really quite shocking. Surely there is something unlawful about publicly firing an employee in this way. All that needed to be said was "Please stop filming".
I generally don't drink coffee because it makes your breath smell. It is really awful when you're talking to colleagues or clients with "coffee breathe".
I agree. I also wonder if many of the great programmers would consider themselves great?
Is there stack ranking even at level 62? :)
What about job applications? Almost every job application requires a degree in CS?
I have an exam in Algorithm Design and Analysis coming up in the first week on July, and have been practicing implementing a number of the algorithm design questions in past papers. They are usually obscure questions around some sort of bin packing or placement. I attempted to implement this question described in the Gist using JavaScript and would like to get some feedback on my attempt. Thanks!
I agree with the enjoyment factor. I hate using BitBucket, I can't quite explain why. It feels neglected and the website layout hasn't been given much thought.
"Github is great for everyone but agencies who have a high number of repositories."
This is the single reason we cannot use GitHub, it would cost £1000s.
I have a student account on GitHub and I use BitBucket for private repositories with my employer. I prefer the GitHub website so much more. Better design, better graphs, you can get an overview of who in your team has committed in a time period (Pulse), better README, better commit history layout, more service hooks (no Trello support for BitBucket is annoying considering we use Trello for organizing and managing our projects), to mention a few.
I do agree that by charging by repository count they are losing a large number of customers who run small web design and development shops. If GitHub price per person rather than per repository, they would gain so many more paid for customers.
