SBB odbija da pomogne svojim korisnicima

July 29, 2008 · 9 Comments

Mi smo tu za njih

Još uvek sam na SBB-ovim prepaid flat paketima, i nakon ovoga što je danas bilo definitivno moram da pređem na postpaid sistem plaćanja (pošto mi se sigurno ne prelazi na Telekom).

Uglavnom se potrefi da zadnji dan trajanja paketa odem i uplatim sledeći paket. Danas nisam mogao da obavim to u toku dana, pa sam predveče zvao korisnički servis da proverim do kada rade. Ljubazna Nikoleta me je obavestila da korisnički centar u Kralja Petra danas radi do 18h. Pretpostavljam da je zbog protesta. I mnogo je glupo ako su zbog toga skratili radno vreme. Kako je tad već prošlo 18h pitao sam da li je moguće na neki drugi način rešiti problem, pošto mi je potreban Internet. Dobio sam odgovor da korisnički centar u Ustaničkoj danas radi do 20h. Kako je lepo od njh što su se potrudili da neki drugi korisnički centar radi puno radno vreme. Možda ipak misle o svojim korisnicima?

Pošto su roditelji išli do grada, onda su oni svratili do Ustaničke 65. Negde posle 20h sam pogledao da li ima novi uplaćen paket i začudio se kad sam video da nema. Zvao sam ih na mobilni i saznao da je i taj centar radio do 18h. Oh, sreće i radosti…

Pošto pre nisam zapazio obaveštenje o skraćenom radnom vremenu ni na sajtu, ni na forumu SBB-a, otišao sam još jednom da vidim da ga nisam nekako prevideo. I zaista ga nema. Zovem opet korisničku podršku, da vidim da li bi mogli da mi učine i da produže paket za jedno veče, pošto već nije bilo obaveštenja i delimično su krivi što danas nisam mogao da uplatim. Na to dobijam odgovor od Marka (ako se tako zvao) da je bilo obaveštenje. Na moje pitanje gde, dobijam odgovor … “Na vratima.” Samo tako, hladno, najnormalnije. Kao da ne živimo u 21. veku, kao da nemaju sajt i forum… Na vratima?! Da li treba svaki dan da idem redom od jednog do drugog uplatnog mesta da bih video obaveštenje? Što nisu mogli na neki pristupačniji način da distribuiraju to? I tako, na još jedno pitanje da li je moguće produžiti Internet za jedan dan, dobijam odgovor da mogu ujutru da uplatim ako hoću…

Eh, Srbijo… Da sam u nekoj razvijenijoj zemlji… prvo se ne bih cimao do korisničkog centra da uplatim. Drugo, bilo bi malo verovatno da zbog protesta skrate radno vreme. Čak i da skrate, verujem da bi bilo obaveštenje na nekom logičnijem mestu, poput njihovog sajta (ili im ta napredna tehnologija služi da reklamiraju “uživajte uz 50 kanala, i Internetu brzine čak 2Mbps od 350 din!”… uz “sitne uslove”). I postoje primeri gde firme izlaze u susret korisnicima i prave ovakve ustupke da bi korisnik bio zadovoljan. Ali ne u Srbiji. Malo ko će to ovde da uradi.

I šta sad mogu da uradim? Ništa, sem da probam da izrazim svoje nezadovoljstvo na ovaj način… I da se nadam da će se situacija ovde nekad promeniti.

Misli o RATEL-u, Uputstvu, Zakonu i Ustavu…

July 25, 2008 · 4 Comments

Dakle, jutros je okačeno famozno Uputstvo, za koje je čuo ceo domaći Internet. Nakon razgovora sa Danicom o ovoj temi, delova Ustava i Zakona o telekomunikacijama, koje sam pročitao na Svakodnevnici i SSpin-ovog komentara na istom postu, malo sam razmišljao o svemu ovome. Ustav je najviši državni akt, i svi Zakoni, Odredbe i ostale stvari treba da budu u skladu sa njim. Daleko sam od pravnika, ali da pokušam da izlažim meni logično obrazloženje. Član 41. i 42. Ustava kažu:

Tajnost pisama i drugih sredstava opštenja

Član 41.

Tajnost pisama i drugih sredstava komuniciranja je nepovrediva.
Odstupanja su dozvoljena samo na određeno vreme i na osnovu odluke suda, ako su neophodna radi vođenja krivičnog postupka ili zaštite bezbednosti Republike Srbije, na način predviđen zakonom.

Zaštita podataka o ličnosti
Član 42.

Zajemčena je zaštita podataka o ličnosti.
Prikupljanje, držanje, obrada i korišćenje podataka o ličnosti uređuju se zakonom.
Zabranjena je i kažnjiva upotreba podataka o ličnosti izvan svrhe za koju su prikupljeni, u skladu sa zakonom, osim za potrebe vođenja krivičnog postupka ili zaštite bezbednosti Republike Srbije, na način predviđen zakonom.
Svako ima pravo da bude obavešten o prikupljenim podacima o svojoj ličnosti, u skladu sa zakonom, i pravo na sudsku zaštitu zbog njihove zloupotrebe.

Dakle, Ustav definiše kada sme da se odstupi od navedenih članova.

Član 55. Zakona o telekomunikacijama, na koji se poziva Uputstvo, kaže:

Javni telekomunikacioni operator je dužan da kao deo sistema, o sopstvenom trošku, oformi podsisteme, uređaje, opremu i instalacije za zakonom ovlašćeni elektronski nadzor određenih telekomunikacija.

Njime se poručuje da je potrebno da operater omogući nadzor korisnika.

Uputstvo, koje se poziva na član 55. Zakona o telekomunikacijama, a trebalo bi da je u skladu sa Ustavom, samo definiše kako se sprovodi elektronski nadzor. I kaže ovo:

Javni telekomunikacioni operator obavezuje se da na zahtev nadležnog državnog organa dostavi podatke o svim komunikacionim sredstvima koja su se pojavljivala na određenoj geografskoj, fizičkoj ili logičkoj lokaciji u minimalnom periodu od poslednjih 48 časova, nezavisno od postojanja telekomunikacione aktivnosti.

Pružalac Internet usluga je dužan da nadležnim državnim organima omogući pristup ažurnoj bazi podataka o pretplatnicima i periodično na zahtev dostavlja eksportovanu bazu podataka u formatu dogovorenom sa nadležnim državnim organima.

Spominje se da na zahtev mora da se omogući pristup podacima. Ima delova gde to nije eksplicitno navedeno, što je možda loše. Ali, ako se Uputstvo oslanja na Ustav, onda bi trebalo da je zabranjen pristup informacijama bez zahteva suda, ili kad nije ugrožena bezbednost Republike Srbije.

To jest, Uputstvom se dozvoljava neograničen pristup informacijama, ali se taj pristup Ustavom i Zakonom o telekomunikacijama ograničava na specijalne slučajeve. Na primer, ako se počini krivično delo 1. januara, a zahtev suda se izda 1. februara, onda bi provajder dostavio traženu komunikaciju od 1. januara do određenog datuma. Moguće je da zato moraju da prate sve podatke. Tako nešto mi deluje razumno.

Voleo bih ako bi ovo pročitao neki pravnik, koji bi mogao da da svoje tumačenje. Možda je ovo tačno, a možda je i samo moj pokušaj samoubeđivanja da je sve u redu…

U svakom slučaju, zdrava doza paranoje nije na odmet ;) . Enkriptujte vaše poruke, razgovore preko IM-ova, i tako te stvari… Čisto radi vaše sigurnosti.

RATEL’s new law and our privacy

July 25, 2008 · 4 Comments

Serbia’s Republic Agency for Telecommunications (RATEL), published the instructions (text in Serbian) on Internet traffic interception and redirection. Basically, it allows Serbian government to read each and every bit of our communication, including HTTP, VoIP, e-mail and IM protocol. It’s not that I have something to hide, it’s just that it’s serious violation of my privacy. And I don’t really like that.

Update: I think I overreacted a bit in my comment. This legal act is not supposed to talk about violation of privacy. Violation of privacy is forbidden by the Serbian Telecommunication law, and Serbian Constitution. The whole purpose of this legal act, as I see it, is to amend element 55. of Telecommunication law.

Another comment can be found here (in Serbian).

Since we can’t change the law immediately, the least we can do is to protect our privacy. We can use encryption methods to encrypt our communication. Here are few advices:

Use HTTPS instead of HTTP

There are web servers that support HTTPS protocol. If you start with HTTP, your browser won’t transfer to HTTPS if it’s possible. So, I advise you to try HTTPS, maybe destination server has support for it. For example, most people will type in facebook.com, which will take them to www.facebook.com, using HTTP. Instead, try typing in https://www.facebook.com. If you’re using Firefox, you’ll notice that the icon next to the address bar is blue. If you click on it, it will inform you that your connection is secured. It should be harder to eavesdrop your connection with www.facebook.com, since it needs to be decrypted first.

Encrypt your e-mails

System of GPG public and secret keys enables to encrypt and decrypt content you need to securely pass to another person. It is possible to use it with e-mails. You need to install GPG software, set it up and generate you public/secret key pair. Then you need to install Enigmail extension if you’re using Thunderbird, or FireGPG if you’re using Gmail’s web interface. For Outlook, GPGol module should work.

Setting up Thunderbird and Enigmail

How to install GPG, and generate public/secret key pair on Linux can be found here. After that is finished, download and install Enigmail. How to install GPG, generate public/secret keypair and install Enigmail on Windows can be found here.

Setting up FireGPG in Gmail.

Just follow the instructions provided on FireGPG download page.

Setting up Outlook

Follow the instructions provided here. It should work with GPGol module, but I can’t test it. I don’t have Windows, nor Outlook.

Encrypt your IM conversations

Update: A list of IM clients that support OTR messaging can be found in Wikipedia’s article about OTR. If you don’t have or don’t like pidgin, you’re free to use something else.

Pidgin, a cross-platform, multi-protocol instant messenger client, has the capability of encryption of instant messages, using Off-the-Record plugin. If you still don’t use Pidgin, I would advise you to install it.

If you’re using Linux, I’m sure you can install it through your package manager. For Debian-based systems, search for pidgin package. Also, OTR plugin is available in pidgin-otr package in Ubuntu gutsy and later, and in Debian testing and unstable.

If you’re using Windows, download the installer from here. It’s easy to setup OTR after, and the instructions can be found here.

After you installed Pidgin, start it and go to Tools -> Extensions. Locate Off-the-Record plugin and enable it. Click on configure button. For each account in the list click Generate, and select Enable private messaging and Automatically initiate private messaging.

Note to some of my friends that use MSN: What do you care more about: your privacy, or animated smilies ;) ?

At the end…

This short tutorial doesn’t cover all protocols… If you know something more, please post a comment and I’ll put it in this post. Thanks.

If you have any questions, post them in the comments, and I (or someone else) will try to answer them.

Adapting Joomla database to UTF8

July 23, 2008 · 6 Comments

Few days ago I was searching for an easy way to adapt MySQL database used by Joomla from latin1 to UTF8 character set. I haven’t found anything, so I wrote this little script.

It’s easy to make a database which uses UTF8 character set when you’re installing Joomla by hand. Though, sometimes your hosting provider doesn’t give you the right to create new databases, so the only way is to install it using some software (cPanel, for example). It will usually set DB to use latin1 encoding. So, after it’s installed we have to modify database and its tables using SQL. This script should do the job, at least for Joomla 1.5, since it’s modifying tables used in Joomla 1.5.

Update: I’m not sure, but altering table jos_users seems to break the passwords. I think you can safely skip it…


ALTER DATABASE CHARACTER SET `utf8` COLLATE `utf8_general_ci`;
ALTER TABLE jos_banner CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_bannerclient CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_bannertrack CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_categories CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_components CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_contact_details CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_content CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_content_frontpage CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_content_rating CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_core_acl_aro CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_core_acl_aro_groups CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_core_acl_aro_map CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_core_acl_aro_sections CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_core_acl_groups_aro_map CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_core_log_items CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_core_log_searches CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_groups CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_menu CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_menu_types CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_messages CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_messages_cfg CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_migration_backlinks CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_modules CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_modules_menu CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_newsfeeds CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_plugins CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_poll_data CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_poll_date CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_poll_menu CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_polls CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_sections CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_session CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_stats_agents CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_templates_menu CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_users CONVERT TO CHARACTER SET `utf8`;
ALTER TABLE jos_weblinks CONVERT TO CHARACTER SET `utf8`;

This script assumes that the prefix of your tables is “jos_”. In case it’s not, just change it in the script. This script can also be applied to any other database. Just open it, and use the names of your tables, instead of these.

In case there is an easier way, I would be thankful if it gets posted in the comments.

Little disclaimer: I’m in no way responsible if something goes wrong. Be careful when you start doing this.

Mozilla team and Ubuntu Hardy Heron

April 19, 2008 · Leave a Comment

This is the first post on the new domain, so I would like to make it a bit special :) .

Hardy Heron will be released in five days, and Ubuntu’s Mozilla team has been quite busy preparing all the goodies. So, what has Mozilla team done?

www.ubuntu.com in Firefox 3 beta 5

Firefox 3 beta 5 is in the official repositories. It replaces the old Firefox 2, which can still be installed from the repositories. It is a pity that Firefox 3 release candidate is coming out few days after Hardy, but Firefox 3 beta 5 is very useful and pretty stable for day-to-day use. Just look at the reviews. And I’m sure we’ll be able to install Firefox 3 as soon as it comes out from Fabien Tassin’s Personal Package Archive.

Also, many members have been testing, editing and packaging Firefox 3 (and upgraded some of Firefox2) extensions for Ubuntu, so this release brings more of them than before. Currently, around 30 extensions are in the repositories. The work is still in progress, so expect more. If you would like to see your favourite extensions, feel free to suggest them at Firefox 3 extensions wiki. Ubufox extension makes it easy to install other extensions. Start it from Tools -> Add-ons -> Get Ubuntu extensions.

Get Ubuntu extensions

Prism, which allows to users to move webapps to their desktop, is also in the repositories. Be sure to check it out.

And, if you feel like living on the wild side, you can test Thunderbird 3 alpha from Fabien’s Personal Package Archive. No links, since this can be very dangerous. You have been warned :) .

Congrats to the whole Mozilla team, and to the Ubuntu community :) .

picfriender.info IM spam

April 2, 2008 · 19 Comments

I have just received a link from a friend over MSN instant messenger that pointed to “her” website on picfriender.info. I clicked it, and saw a homepage which asked me for my MSN username and password. Why would they need it? If I needed an account to visit her website, I would need to make a new one. So, the only logical thing is they would use it to get access to my account. Well, it seemed like a spam company, so I googled them. Strangely, Google knows nothing about them for now.

Then I noticed a link to their Terms of Service, and I wasn’t surprised to read this…

“We may temporarily access your MSN account to do a combination
of the following:
1. Send Instant Messages to your friends promoting this site.
2. Introduce new entertaining sites to your friends via Instant Messages.”

It doesn’t smell only like spam, it is spam. Sort of legalised, though. I hope they will be closed soon. Be sure to not give them your account information, unless you want them to send annoying links to your friends. Some of them may fall for this too… And the chain reaction begins.

In case you already gave out your personal information, the fix should be simple. Just change your password over at MSN Passport/Windows Live ID website.

Update: I have just checked the information about this website, and I found out that it was registered less than 10 hours ago. It’s logical why Google still knows nothing about it…

Update #2: It seems that this is not new, Aeriff wrote a blog post on this on March 15th. The only difference is the more logical domain name (picfriender.info vs. rkntbp.info)…
