I made this a while back http://www.soundcloudwall.com/
_grrr··on Tim O'Reilly: I am really starting to hate Mac OS X.
Just installed Linux Mint - I love it! A real improvement over the bloated Ubuntu 11.10 release and Unity. It's fast to startup and shutdown, responsive and has a lovely UI.
_grrr··on Linux Mint: The new Ubuntu?
Having now installed Mint 11 I can say it it's a real improvement over Ubuntu 11. Fast to load and shutdown, responsive, beautiful UI.
_grrr··on Linux Mint: The new Ubuntu?
Yesterday I upgraded to Ubuntu 11.10, having already regretted going from 10.10 to 11.04.

In 11.04 the Gnome fall back just about worked. In 11.10 it does not. As for Unity I can't tell whether it's working as intended or is buggy.

Every progressive update from 10.04 has gotten increasingly slow to boot and respond.

As we speak I'm preparing to install Mint, with a fall back to Ubuntu 10.10.

_grrr··on The Number One Trait of a Great Developer
I always go by the maxim: "(build) the right thing at the right time". I think John Bentley said that.
_grrr··on The LMAX Architecture - 100K TPS at Less than 1ms Latency
The hand off between producer and consumer can be configured to be both synchronous (single threaded) as well as asynchronous (one producer thread, many consumers threads).
_grrr··on The LMAX Architecture - 100K TPS at Less than 1ms Latency
As far as I understand three of the key features are:

1. Reduced queue contention: queues are typically implemented with a list, e.g. linked list, this introduces contention (queues spend a lot of time empty or very full) for the head and tail of the queue which are often the same dummy node. The ring buffer removes this contention.

2. Machine Sympathy vis a vis cache striding and ensuring concurrent threads are not invalidating each others level 1/2 cache.

3. Pre-allocation of queue data structures to ensure GC is not a factor.

Personally I think the LMAX team have done well in advancing the state of the art in what is often a key component in event driven, high throughput low latency systems such as those used in banks for trading, exchanges and market data.

_grrr··on An Elephant Burial
That mammals other than humans are capable of emotion and concious thought comes as no surprise to me. Why some humans derive pleasure from inflicting unnecessary cruelty towards other beasts I will never understand.

_grrr··on Why The UK Startup Scene Is Doomed
Wow, we had EXACTLY the same experience.

A lengthy process (about 3 months) to get signed up with Sage Pay only to be declined the merchant account (yet to give us a reason although they said they would tell us, that was 2 months ago).

We ended up settling on PayPal just to get started, not ideal for taking recurring payments, but quick, easy and better than nothing.

_grrr··on Show HN: A search engine for your browsing history
Agreed that Chrome's history search provides similar functionality, although it is somewhat clunky to use. For example, you can not constrain results by time period.

In addition, unlike normal Google search results the history search seems to weight every word on the page equally, in recawl there is an attempt to prioritise body content whilst ignoring repeating menus & footers, and it is built on top of Lucene's excellent scoring function.

In addition for any gives search terms it learns to prefer the search results you click on, so that over time if you constantly search your history for the same or similar search terms then historical results you have already clicked on bubble up to the top.

This makes it quite a useful tool for recalling often used pages.

It also offers keywords related to your search to further help narrow down your query.

Finally, you can block certain sites that you know are not of interest from appearing in search results, again cutting down on noise.

Finally, being able to remotely search your history can come in really handy.

_grrr··on Eric Schmidt criticises education in the UK
Except I honestly don't think these answers weren't meant to be sarcastic. I sometimes skim through Guardian comments and these seem par for the course.
_grrr··on Show HN: Recawl - a search engine for your web history
It does, but it also has bookmarks and there are a number of bookmarking services that all improve on the basic browser offering in some way.

When I first started Recawl Chrome's history search was somewhat unreliable/buggy although it has improved since then.

I also find Chrome's history search hard to use.

For example:

You cann't constrain a search by time period and you cann't block sites from appearing in the results.

Recawl suggests keywords related to your current search and it also learns to re-order results for search terms based on your previous click history.

Your Recawl history is available to search remotely whereas Chrome's history is only local.

_grrr··on Show HN: My 10 minute non-project: Get a weekly digest of emails from any source
and beyond proposing an idea, and collecting emails, what does this submission contribute?
_grrr··on Google Bot Attempts to Crawl Shortest URLs First
A poor mans PageRank algorithm, assuming nothing else, would assign a higher PageRank to shorter site links on a page. Presumably the crawler visits pages with a higher PR first.
_grrr··on The Linux desktop experience is killing Linux on the desktop
I've been putting off the update to 11.04 from 10.10, is it relatively pain free?

Quite a few revisions since first posted to HN!

_grrr··on How to Spy On Your Competition
Should be fixed now if you want to have another go...
_grrr··on How to Spy On Your Competition
Thanks for trying it out. There was an issue with sites that redirect from http to https. Just putting in a fix and will ping you when done.
_grrr··on How to Spy On Your Competition
On this topic we've just launched a hosted competitor monitoring service, http://www.webalertpro.com

It's a website content monitoring service that generates daily reports for all content changes for all your competitors websites.

It was a quite an interesting technical challenge since most sites generate loads of small unimportant changes (and text moving around in lists, dynamic news reels, dates etc..) of no interest to anyone. So the approach we tool was to rank each change. So when a user adds a new site to monitor the first few days of crawling it are spent learning where the important content changes take place on the site. We can then report assign to each change alert a score between 1 and 10 (ChangeRank!).

We're getting quite some interest in the applications of this, from campaign monitoring, marketing compliance and figuring out what content changes your competitors are making for the purpose of SEO.

_grrr··on Clean Up Your Mess - A Guide to Visual Design for Everybody
Did anyone else find the Aikido flyer on the left the most readable? The version on the right might be 'neater' but I was able to absorb the information from the left version more easily.
_grrr··on Information Physics: The New Frontier
I always thought that was what all Physical models were, a best approximation, given the empirical data available at the time.

Nothing wrong with the basic design. It's functional, and conveys information....makes a change from rounded corners etc etc.
_grrr··on Convore (YC W11) Wants To Be The Easiest Group Communication App Yet
I wonder how they will monetize this? A white-label chat platform for websites that want a chat facility would be one option (StackOverflow rolled out chat recently, but this would have been a good candidate for them). Branded in-house chat for corporates would be another, especially those with distributed project teams that want to communicate around a project. I like the fact that the chat sessions are persistent and revolve around a topic - this makes them very useful in a project environment.
