The Biochemistry of Searching the Internet

alxtoth why Safari/OS X generates files Downloads-1-1? (63 comments)

Was this web page written by evil crackers ? Why is my beloved Mac writing files called /Users/Downloads-1-1, Downloads-1-2 ??? This freaks me out, because I've been told there are NO VIRUSES FOR MAC !!! Seriously, there is a fresh discussion in Apple forums, http://discussions.apple.com/thread.jspa?threadID=2113155&tstart=0&start=0. This is a (sad thing) pow 2 : Mac vulnerabilities , coming from Slashdot

RAID Trust Issues — Windows Or a Cheap Controller?

alxtoth Re:RAID1 is not fool's gold (564 comments)

Actually RAID1 is quite good for reading data: it minimizes seek time . Of course, it works fine as long as there are not many writes. For example think analytic databases, cubes, etc. Those are not written to in real time (like the more common transactional databases)

Linux patch to circumvent Microsoft's FAT patent

alxtoth only short & only long (2 comments)

Wonder if keeping only a short name and a long name won't break backwards compatibility. For example if the volume is mounted on Linux, written to, and plugged into a Windows box .Or another device, implementing another subset of the undocumented FAT

Virtualbox 3.0 Announces OpenGL/Direct3D Support

alxtoth VirtualBox is nice without any 3D acceleration (161 comments)

I've been using VirtualBox to run some closed source software on my laptop. With WmWare, it barely worked. with VirtualBox, I was even able to make a cluster between the apps between the two virtual OSes (on same laptop), with decent performance. Setting up the network needed some tinkering, but after that it worked like a charm. Great piece of software ! I couldn't care less for the sound and 3D stuff as long as they don't break the core functionality

Nokia sellout bonus to former CEO Ollila similar to Elop's

alxtoth alxtoth writes  |  about a year ago

alxtoth (914920) writes "People are angry about Stephen Elop for "selling out" Nokia to Microsoft. Former CEO Jorma Ollila is regarded as the founder who had turned Nokia into a telecom giant and was was forced to leave his position as chairman when the Microsoft deal happened. Finnish newspaper Iltasanomat breaks the news that mr Ollila's bonus for the deal might be similar to Elop's, and that Ollila might join Microsoft's board. http://www.iltasanomat.fi/digi/art-1288595403667.html"

Whatever happened to hashcash ?

alxtoth alxtoth writes  |  more than 6 years ago

alxtoth writes "Hashcash ( http://www.hashcash.org/ ) was well coverred in themedia around 2004. Briefly, it is a technology to burn CPU cycles if one wants to send email, and as consequence reducing the volumes of spam that bots can send. There are also Javascript implementations for combating link spam. Misteriously, since 2004 hashcash is silent, except for a Wordpress plugin from 2008. The Wikipedia article on hashcash ( http://en.wikipedia.org/wiki/Hashcash ) has a link about a future IETF standard ( http://www.ietf.org/ietf/IPR/rsa-ipr-draft-jennings-sip-hashcash-00.txt ). The last link states "If use of client puzzles is incorporated into a future Internet standard, and if the currently active application leads to an issued patent, RSA Security Inc. is willing to grant licenses to such patent under reasonable and non-discriminatory terms for purposes of implementing that Internet standard". The question is: if there is no patent infringement, why isn't Hashcash used more to prevent email and comment spam?"

Grapcha - Captcha tool based on Graphviz graphs

alxtoth alxtoth writes  |  more than 6 years ago

alxtoth writes "Why are the captchas always small? Grapcha makes big images, and hopefully easy to read while hard to break. Start reading at the green "diamond" and stop at the red "square". Ignore the eventual random padding at the beginning and end. Here is an example how Slashdot is renderred : http://snowflakejoins.com/grapcha/index?text=www.slashdot.org . The site has the BSD licensed code too."

Reverse Snowflake Joins - demo site

alxtoth alxtoth writes  |  more than 6 years ago

alxtoth writes "Reverse Snowflake Joins now has a demo site http://snowflakejoins.com/revj/index . It is a tool for understanding SQL queries, and documentation. The tool shows the eventual cartesian joins and loops (legitimate, or by mistake). There was some progress since the last slashdotting ( http://developers.slashdot.org/article.pl?sid=08/08/03/1915258 ). Cheers, Alex"

Snowflake query diagramming tool

alxtoth alxtoth writes  |  more than 6 years ago

alxtoth (914920) writes "There is a new open source tool that parses SQL Select statements and generates a diagram. It shows parts of the underlying SQL directly in the diagram. For example x=30 , GROUP BY (year), SUM(sales), HAVING MIN(age) > 18. The primary reason for the tool was to avoid cartesian joins and loops in SQL written by hand, with many joined tables. The database will execute such a syntactically correct statement, resulting in runaway queries that can bring the database down. If you sit close to the DBA's, you can hear them screaming .. License is BSD, and link: http://sourceforge.net/projects/revj/"

can adds support an open-source project?

alxtoth alxtoth writes  |  more than 6 years ago

alxtoth (914920) writes "I am about to start a new project. Thinking how can I make money with it while keeping it open source. Usual advice is: sell the support and customizations. But knowing the project, support seems hard to sell: either works with first click, either doesn't. What do you think, can a small project support itself by offering a registration-free online site with full functionality by displaying text adds? Myself wouldn't bother to register as long as I can download the code; but using it anonymously online saves the installation. Also, making part of code free and part closed pisses off the open source community from the very beginning."

Intel vs PowerPC performance .. increase?

alxtoth alxtoth writes  |  more than 6 years ago

alxtoth writes "Latest official performance numbers from Apple Inc compare 4 cores PowerPC G5 from 2005 with the latest-and-the-greatest 8 cores Intel. Intel has faster memory, faster buses, more cache, faster SAS drives. Top speed increases are: 2.9X for Mathematica, 3X for Cinebench and 4X for "modo 301 3D rendering". Note that most applications have speedups between 2X and 2.9X. According to Moore's law (http://en.wikipedia.org/wiki/Moore's_law) "bang for the buck" doubles every 24 months. The number of cores concretely doubled in this test. Indeed there is progress with Apple marketshare, but still fail to see "revolutionary" performance increases. Do you?"

It is definitively good news that Sun is back in business, but this machine is little pricey compared to now defunct PowerMac G5 (dual-core, 2.5Ghz). The system looks as having big memory and disk bandwidth, but in the past UltraSparc was strugling when compared to equally clocked PowerPC (and is "only" 1.34 GHz). Will this system be as popular as the Ultra 2?"
