    Brief comparison: Dropbox vs BitTorrent Sync vs AeroFS vs SparkleShare

    24th November 2013

    Right now I’m mostly using Dropbox, and recently started BitTorrent Sync for my music collection sync between all the PCs and my backups server, as well as for sharing larger files at work (thanks to direct LAN connections, this is much faster with BTSync than with Dropbox, which has to first upload the file to Dropbox server). I’m also considering syncing a TrueCrypt container of my photos archive using BTSync. SparkleShare is potentially interesting, but given my trend to move to free code-hosting services, I do not yet see a need for it.

    Below is a short summary table I’ve used to compare available solutions. Feel free to contribute to the table in the comments – I’ll update the post, then.

    The Mysteries of BitCoin

    24th November 2013

    BitCoin logoDid you know that the creator(s) of BitCoin is/are unknown?
    Did you know that the account which generated the Genesis Block is estimated to have up to 0.6-1 million BitCoins?
    Did you know that the creator(s) of BitCoin disappeared from any BitCoin-related discussion and development forums a long time ago?
    Did you know that 3 journalist investigations aiming to identify BitCoin creator(s) all ended up with different results?

    This information is not available in one piece, but there are some of the pieces at the following URLs:

    Outlook 2010: MAPI was unable to load the information service gwmsp1.dll

    24th November 2013

    If you try starting Outlook 2010 and get an error like this:
    “Outlook 2010 cannot open your default e-mail folders. An unexpected error has occurred. MAPI was unable to load the information service gwmsp1.dll”

    you can easily fix this problem by going to Control Panel, clicking on Mail, then Show Profiles button.
    Remove everything that’s there. Now start outlook again.

    Note: removing all the mail profiles will disable your Novell Groupwise client.
    If you still want to use non-Outlook email profiles, then the better solution is to manually create a new mail profile for Outlook.

    The list of spammers emails

    13th November 2013

    All sane people agree that spam is a blight of the internet, be it email spam or comments spam or forum spam or any other form of unsolicited, blatant, shameless, out-of-context advertising. Multiple spam-fighting and spam-stopping systems are being developed.

    With automated spam, automated spam-fighting systems might be the only choice. Sending rightfully angry emails to ISPs to notify about their customers violating service agreements is probably a waste of effort (something tells me most of these complaints end up in the trash folder, or even in the… spam folder). However, I get a feeling that some spam is not automated – it appears to have been actually prepared and sent by a human. (Alternatively, spammers behind those spams simply have better software.) Anyway, some spams seem to contain valid contact data of the advertized entity – like an email.

    The resulting idea is very simple and was probably already implemented somewhere by someone: simply publish online contact emails of the entities which, apparently, had chosen spam as the primary means of advertising. These emails will be sooner or later harvested by spammers, added to spam databases, and will start getting progressively more spam.

    There are a few drawbacks to this approach:

    • knowing spam-collection points enables “black PR”-like mass-mailings in the name of one’s competitor, double-hurting the innocents; I do not see a clear method of preventing this, other than by concealing spam collection methods;
    • human intelligence is required to identify if the contained email truly belongs to the advertised entity; this is fairly time-consuming, especially when scaled up; a possible solution (with its own problems) would be to build an online gateway for submitting curated spam samples, thus distributing the workload to all the participating volunteers;
    • the next logical step is actually harvesting and then publishing all the emails from the advertised website;
    • the biggest drawback, however, is low efficiency of this approach; increasing spam percentage will only be a mild nuisance, which isn’t likely to propagate high enough to affect spam-deciders; also, indirectly spamming someone’s mailbox will result in the loss of time, which could have been otherwise used for facebook and other important activities :)

    What do you think? Should such a method be used?

    Below I provide a few sample records from real spam comments, which had true-looking emails. I’m including some extra meta-data. Ideally, this should be stored in some kind of a database.

    There’s definitely a need for a public database, API keys, and quorum algorithms…
