  1. A distributed DoS attack on Mozilla 1.2 Unleashed · · Score: 1

    You just have to change a super-visited site (e.g., slashdot) template to load other site pages (specialy database generated ones). Now every visitor will unknownly download pages of this other site. What about that for a distributed Denial of Service attack?

    At least the REFERER log will show the offending site.

  2. Not just Europe on EMI Customer Relations Tells It Like It Is · · Score: 1

    They also are starting to sell "protected" CDs in Brazil.

  3. They are crazy with the complaints on EMI Customer Relations Tells It Like It Is · · Score: 2, Interesting

    I can just find an explanation for this kind of answer: there are so many complaints that the consumer answer guy can't stand it anymore and started to spit in anyone that asks.

  4. Joining images on Portable Scanner Solutions for Research? · · Score: 1

    My canon digital camera came with a little marvelous software: photo stich. It automagically joins adjacent imagens as if they where just one. I believe there is comercial or free softwares like this.

  5. Corrections Re:Wrapping up on Electronic Ballots In The Brazilian Presidential Election · · Score: 1

    Not all votes are electronic. There are some remote places where I'm not sure if it's already electronic,

    This year they tried to make ALL voting eletronic. Except for the 1% of failed ballots, this happened.

    (ii) There is a paper backup system

    No, there isn't a paper backup system. Just a few ballots register the votes in paper. Almost all doesn't have any possiblity of audit.

  6. On line SQL book on Best Computer Books For The Smart · · Score: 1

    I really like this on line sql book, by Philip Greenspun. I doens't waste time.

  7. Re:testing tools on Automatic Functional Testing for Mac and Linux? · · Score: 1

    No. From their site: OpenSTA graphs both virtual user response times and resource utilization information from all Web Servers, Application Servers, Database Servers and Operating Platforms under test, so that precise performance measurements can be gathered during load tests and analysis on these measurements can be performed.

  8. Email regex on Next Generation Regexp · · Score: 1
    In my CGI scripts, I never make assumptions about how valid an arbitrary email address is. Instead, the script sends mail to it and expects a reply. Only then can I tell the address is indeed valid.

    So you miss the chance to build a good user interface. If you verify the email address with a regex, you could present a decent error message to the user that has just made a typo. Maybe he typed "username@hotmail.co", so before sending him an email, you can right on ask for the correct address. If the user leaves your site, you won't be able to contact him anymore.

    I go further, even checking for common errors and suggesting the correct address. Did the user entered "username@hotmail.com.br" or maybe "www.user@isp.com", they I warn that the address is probably incorrect and suggest "username@hotmail.com" and "user@isp.com" even before accepting the input.

    An user email is a valuable asset. The first step building a long relationship. Don't miss the chance to get it right on the first time.

  9. Re:The same happens here in South America on African ISPs Being Fleeced by the West · · Score: 1

    Even worse is the fact that since Worldcom bought Embratel (the big Brazilian carrier) two years ago, they've cancelled all regional IP links we used to have. Now they want to force us into buying BW only to the US.

    Brazil have (not very strict) laws about multinational companies sending profits home. Paying directly to USA, they don't have to obey these laws.

  10. I'll just believe we will get a paperless office.. on The Myth of the Paperless Office · · Score: 1

    ...when someone invents a paperless toilet.

  11. Plucker and forms on Web Access on Handhelds · · Score: 1

    You can't use forms in Plucker.

  12. Self serving ads on Announcing Slashdot Subscriptions · · Score: 1

    Remember, ./ already have self serving ads.

  13. Re:What is a page? How much is enough? on Announcing Slashdot Subscriptions · · Score: 1

    10% is too much. Real paying subscribers numbers are no more 5% (and nearer 1%).

  14. Re:Hobby vs. Profession on PressPlay and MusicNet vs. Artists · · Score: 1

    Don't forget that there are a lot of artists that are just composers, they don't perform. Musicians like Cole Porter and Irving Berlin (to stay in american examples) just make songs for others to perform.

  15. Re:Why vert marketing sucks in the music industry. on PressPlay and MusicNet vs. Artists · · Score: 1

    Don't forget, they also control what you hear in the radio. If you don't have money to pay the radiostations to play your music, the public can't hear you.

  16. Re:Someone has to objectively verify . . . on PressPlay and MusicNet vs. Artists · · Score: 1
    Isn't there some way to obtain empirical data to determine whether (1) or (2) is the most valid world view? For example, could a program be devised to crawl out over Gnutella and track and compile download frequency data of file names, to see whether most downloading is focused on the big money pop groups as the industry claims? If that's too scary, could some university department with expertise in such things conduct a reliable blinded survey, or arrange a study of this behavior? When the two sides of the debate have such different perceptions about what is actually occuring, it's difficult to see how progress can ever be made.

    Do you want some statistics? I'll give you some cheap ones. So cheap that I didn't even need to research to get them!!!:-)

    If you measure it, you will find that the data follows Zipf's Law. This is the law that reigns the frequency of english words in a text, the most visited web sites, and a lot of other interesting things. It is an exponencial curve, where very few data has a very high frequency (i.e. the word "the" in english texts, yahoo and hotmail in the web), and a huge amount of data has very low frequency.

    The most important thing to remember is that although the hundred most visited sites may have 40% of the time users on line, the majority of the web and of the time spend in it are in the small sites. Even if very few have a lot of influence, the web is still the land of diversity. In radio, TV and big newspapers, you just have a hand full of genres and points of view. In the web and napster you have variety.

  17. Re:if you want to help the artist... on PressPlay and MusicNet vs. Artists · · Score: 1

    The composer gains no money.

  18. Microsoft patented it on Xft Support For Mozilla · · Score: 1

    It looks like Micro$oft patented it. Can you use it in an open source software without being processed?

  19. LaTeX text editor on Writing Documentation · · Score: 1

    (X)Emacs has a great LaTeX mode. The referencing mode LaTexRef is really cool.

  20. Buy a Latex book on Writing Documentation · · Score: 1

    If you really want to use anything non-trivail latex, my advice: buy a book. I don't know them all, but I like "A guide to Latex" (Helmut Kopka & Patrick W. Daly).

  21. Re:Right back into the swing of things on U.S. Penalizes Ukraine for Abetting 'Piracy' · · Score: 1

    Reading posts like yours, I don't feel jealous of USA. Just more afraid of it.

  22. You lost this thread on Monsanto and PCBs · · Score: 1

    Why to argue this much? Guy, you lost due to Goldwin's Law.

  23. Art is Art on Money in the Music Business · · Score: 1

    It is a testament to their ingenuity that they are able to make such huge profits by developing a successful formula to minimize losses on crappy bands (the 95%) and maximize profits on good bands (the 5%).

    Great, The good bands are the ones that sell more! I've always thought the best were the ones that touch me the most.

    Record companies are evil, not because they pay little money to musicians, but because they control the media and marketplace to forbid music diversity. You'll just be able to hear in TV and radio three or four genres, where all the bands sound the same. No originality. No emotion. No creativity. No art.

  24. What's the best mod_gzip configuration? on Dump Broadband, Dig Out Your Modem! · · Score: 1
    Mod_gzip isn't always better. If you have to compress your page, your user will have to download it all before visualizing. If you code well your page, instead of coding it as one big table (You don't do it, do you?), you allow people to start reading as it downloads, then the perceived download time is SLOWER with mod_gzip.

    The page may download faster with mod_gzip, buy the the latency to compress and download it all before visualizing may be greater than the time needded to see a good amount of it.

    If the user can start to interact with your page before it is fully downloaded, the perceived download time and user experience can be better.

    So I ask: what's the best configuration of mod_gzip. What's the page size that's (compression time + download all compressed page) < (download 50% of page)?

    BTW, I installed mod_gzip in my server. One fantastic thing is to also turn on mod_negociation. If you have static pages, you can leave them already gziped in your HD that Apache will serve it as is. It's a win-win-win-win!!! You save space in your server, you spend less bandwith, the page downloads faster, and your server don't spend processing power compressing it!

  25. I'd love a slow broadband on Dump Broadband, Dig Out Your Modem! · · Score: 2, Insightful

    I'd love to have a cheap and slow (e.g., 64K) connection where I could stay on line 24h a day. What bothers me the most is the need to connect each time I want to verify an email or visit an URL when I'm in a dial up.

    You sure have a market for this out of USA. Remember that out of the USA, you have to pay your telecom company for the time you use your phone in local calls. Here in Brazil we have to connect, download the emails, disconect, reply all, select the URLs you want to visit, connect, visit each URL and have your email sent, disconnect, read everything, connect, follow some links, disconnect,...
