» On CalDAV and Google.

People are annoyed about the demise of Google Reader. Yet more than Google Reader, a service I’ve used and loved for more than 7 years, I am truly annoyed by the fact that Google is canning CalDAV. And not just because CalDAV is an open, free and widely used protocol (all very good things), but because, in the past, Google has been a champion of open protocols, because its support for CalDAV was reaffirmed only two months ago when it dropped Exchange Support from its Google Docs apps. Because it demonstrates that Google has been somewhat cavalier with its use of ‘Openness’.



Using OTE’s 11888 to provide fast CLID data for FreePBX/Asterisk

For those using FreePBX (a configuration/administrative interface that manages Asterisk) there is a CallerID Lookup module, published by the FreePBX team. The module allows you to interface with data sources using several methods, one of them being http.

Like many companies, we maintain several systems that can be easily integrated with our VoIP PBX system, but we also receive a number of calls from the public, viz. companies interested in advertising on GEO|ADS, adding their business to AthensBook or ThessBook, or asking for a quote for a project. OTE recently revamped its aging whitepages.gr site and incorporated its content into their ‘umbrella’ 11888 business directory operation. The new site is faster, more beautiful and written in a more professional manner, as far as the markup is concerned, which makes it a perfect source of caller id information for a large number of telephone subscribers in Greece. Around one hour of Ruby scripting using Mechanize, Sinatra and some custom transliteration tables to convert the scraped names to their latinised counterparts (Cisco phones don’t seem to like Greek characters all that much) resulted in the following script (github)

Δεν ξέρω αν θα ήμασταν πάνω από την μεγάλη πλειοψηφία των Αφρικανικών χωρών στο Web Index του Tim Berners Lee, αλλά είμαι βέβαιος πως το γεγονός πως δεν είμαστε πουθενά στην κατάταξη είναι δείγμα της έλλειψης σοβαρότητας, ενδιαφέροντος και αξίας που δίνουμε στην δικτύωσή μας ως χώρα. Αν μη τι άλλο, εν διαμέσω κρίσης, οι επενδύσεις για την βελτίωση των δικτύων ευρυζωνικότητας φαίνεται να έχουν παύσει, οι επιδόσεις των υφιστάμενων συνδέσεων έχουν παγώσει ή χειροτερέψει για πολύ κόσμο και εκεί που η Ευρώπη περνά ταχύτατα σε δίκτυα νέας γενιάς με ευρεία διαθεσιμότητα VDSL2+ και FTTC/FTTB/FTTH εμείς ακόμη συζητούμε για εγκατάσταση περισσότερων mini DSLAMs έτσι ώστε να μην βρίσκεται η μεγάλη πλειοψηφία των συμπολιτών μας καταδικασμένη σε ταχύτητες κάτω των 5-6MBps. Φυσικά, στα μάτια των πολλών, όταν το διακύβευμα είναι η ίδια η επιβίωση, η ευρυζωνικότητα καταντά ένα γραφικό αντικείμενο συζήτησης. Κι’όμως, αν μη τι άλλο, αν η ‘ανταγωνιστικότητα’ της Ελλάδος θέλουμε να σημαίνει κάτι παραπάνω από την εξαθλίωση του βιοτικού επιπέδου των κατοίκων της, αν ο στόχος μας δεν είναι η εργατική τάξη, η αποδοτικότητα του δημοσίου ή η διαφθορά της Κίνας ή της Ινδίας αλλά αυτές της Σουηδίας ή της Φινλανδίας, τότε η ευρυζωνικότητα θα έπρεπε να θεωρείται μείζον θέμα στους κύκλους των αρμόδιων υπηρεσιών και υπουργείων. Και προφανώς αυτό σημαίνει πως η Ελλάδα — μάλλον — θα έπρεπε να εμφανίζεται στο ευρετήριο του Tim Berners Lee και δη σε θέση που δεν θα μας προκαλούσε συλλογικά κατάθλιψη.


»  Hotmail

In the summer of 1996 hotmail was released to the world and it wasn’t much later that I opened my first account there. It was an innovative email platform that promised to liberate people from their ISP provided email. It was one of my first non-ISP provided email addresses and one I still have. Like today, the mid-1990s was an era of walled-gardens, only at the time they weren’t called Facebook, twitter or Google, but AOL, Compuserve and loads of local BBSes offered by several small ISPs. Service providers were only beginning to adopt their, still current, position as ‘carriers of content and services’ not purveyors thereof. And in this environment, hotmail was innovative, in the same way that netflix, skype and all those other unbundled services are innovative for they liberate you from the increasingly threatening grip of ISPs and the few dominant players that keep entering new markets, doing a bad job at it, but winning ’cause their financial prowess kills the competition in the meantime. I used to use my hotmail account quite a bit between 1997 and 1999. I gave up shortly after Microsoft started really changing it — at the beginning they didn’t do much to it; it still ran on FreeBSD and Solaris. By 2001 it had already lost much of its ‘innovative’ features (and it ran on Windows 2000) and under Microsoft’s ownership it stagnated as other services rendered it obsolete. By 2002, my hotmail account was only used for a few quasi-dodgy online merchants to whom I didn’t want to give a more ‘important’ email address and since GMail took the world by storm with its 1GB offer in 2004, I practically stopped using it alltogether. As such it is now full of enough spam to feed the world twice over. And now, Microsoft decided that hotmail is to be no more, replaced by the title of its equally mediocre monstrosity of an email client, Outlook, and revamped to look like an app of their Metro environment. Yet another one of those early, pioneering web brands of the 1990s is, even in name, dead. Ah well, at least we still have Amazon =)



On Device Identifiers.

Mere hours after pressing ‘Publish’ on the previous mini-article concerning walled gardens, an article on TechCrunch, this morning, clarified the situation we have more or less been suspecting for a while now: that Apple, after deprecating UDIDs (one of the things they truly did well in iOS from the beginning), they will start rejecting apps after the backlash caused by lawsuits, noise and a few rogue developers that seemed keen to take advantage of their users and use their private information in ways they didn’t agree (and which are illegal in more ways than one).

The situation with unique device identifiers is an important one. On one hand, user privacy should be the number one concern of platform owners/builders like Apple, Google and Microsoft. It isn’t, for their software can do pretty much whatever it wants with the users’ private information, as we have seen several times these past few years. On the other, developers have many uses for an immutable, unique identifier for devices; from providing metrics for their own use, understanding the patterns of use of their applications, improving ad targeting, enforcing proper use of their applications and communities among others. Of course, it can also be a tool aiding in unsolicited tracking and profiling of users, of a range of personal information violations etc.

When Google came out with Android, they failed to provide any sort of unique device identifier of any significance to their developer community. They did provide several ways for developers to get some seemingly unique identifier, but those were easily modifiable, sometimes were not set at all or set to the same value across all devices sold by an OEM. In addition they would get reset after a factory wipe, etc. Developers resorted to DIY identifiers, scoured and composed from several unique component identifiers available to them by the system, such as the IMEI in phone devices, or the MAC address of the WiFi network interface in others. Then Google released Android 2.3 which included a unique identifier which, while better than the previous ones, was still not 100% robust.

Microsoft has belatedly joined the new-walled-garden era, first with Windows Phone 7 and now with Windows 8. The ‘new’ API and model for applications, Metro, goes one step further by not providing any single unique device identification capability to developers (there are some exceptions, but they are truly exceptional and as of right now undocumented). The only thing close to user/device authentication is ‘Microsoft Account’ (formerly Windows Live, Passport etc. etc.) integration which is probably useless for 99% of the cross-platform applications available out there, that have a need for some sort of unique identification of their users/devices.

It’s the permissions stupid.

The whole situation boils down to botched design in terms of permission control, abuse by advertising, analytics and developers and extremely late regulatory and social reaction to the above, perhaps combined with a pretty simple way to raise barriers to entry to the competition while ‘solving’ the issue of privacy. All platforms have some sort of privacy/permission control, but none have a good one. Android has a pretty comprehensive permission system that assumes that before installing an application each user bothers to read a silly list of permissions (many of which they will probably not understand) and once they accept they will perpetually want to grant all those permissions to said application. There is no fine grained permission control post installation, no possibility to grant or revoke individual permissions to applications before they are launched (something like “I would like to allow App X to use my network connection, but not my location or my address book data”). iOS is also similarly badly designed: there is no explicit permission asked or required for using the network connection, a slew of personal data, several APIs, storage etc., except for location, where iOS does a much better job than Android, probably because of the high-profile exposure that their data-collection ‘functionality’ took a few years ago. At the same time, both platforms actively transmit information gathered by your device, be it nearby BSSIDs (the identifiers of wifi networks, akin to ethernet MAC addresses) or Cell IDs (the unique identifiers of nearby cellular transmitter/antennae) so that they improve their ‘network-based’ geolocation service. Google fares better in this respect, as they allow you to disable this; Apple doesn’t, as far as I know.

Then comes Microsoft, the ailing software behemoth that only recently decided that Balmer’s rhetoric about the iPhone’s failings, the iPad not gaining any significant traction etc. was totally wrong after all, and that they should jump on the tablet bandwagon, not in the way they’ve been trying to do for about a decade, but the way Apple did with their own version of a walled garden, doing away with the desktop paradigm and providing a dumbed down, simpler interface that does away with compatibility, file-systems etc and uses a locked down, app store/marketplace based model to ensure software legitimacy and boost profits. So Windows Phone 7 and Windows 8 provide new sets of APIs and a new ‘application environment’ called Metro. In the Windows 8 version, the æsthetics borrow much more than its name from Windows Phone 7, the company’s revamped operating system for mobile phones that, while a decent effort, doesn’t seem to be doing that great on the market. Metro on Windows 8, however, is not a finished product by any means, and probably won’t be ‘finished’ (that is of a sufficiently high quality) until Windows 9 is released in a few years from now. Metro on Windows 8 also has permissions, like Android, but does away with unique device identifiers and any sort of meaningful API to get any sort of replacement of one. It also allows the user to revoke a permission (say, for the location), but only after the application has be executed, which kind of defeats the purpose.

My experience with the ‘next-generation’ platforms I have programmed on until now strongly suggests that the companies and people designing them have no idea about the implications of their work. They are experimenting, releasing APIs, platforms and products without thinking them through, or the impact their software has on the users, developers building applications using them or the overall social effect of their design decisions. In the case of Android, many more developers have access to IMEIs, MAC addresses and other, arguably much more sensitive information about devices and their users than they would have, had Google paid some attention and provided a unique, immutable pseudo-random unique device identifier from day one. It is also surprising how bad their permissions system is, given that they at least went through the trouble of designing one in the first place. In the case of Microsoft, the complete lack of such a mechanism, may eventually play its part in hurting the company’s efforts to enter the game (they already are extremely late). And finally, Apple, the market leader that did so many things right in the first place, is risking pissing off everybody from small independent companies that helped build the platform, to its greatest non-platform owning competitors that can see through the excuse of legal heat from regulators and the government, their hypocrisy on protecting the users’ privacy and who may call their action as an excuse to block them out of their platform. At the end of the day, the three big players in this market still get all your information, and their expansion into advertising, mobile payments, e-commerce and every single part of the software ecosystem possible means that they have the greatest incentive to (ab)use it.

In the end, all of the privacy problems that location, unique device identification and access to other personal information may give rise to are easily solvable by a modern, smart permission system that gives the user the power to deny, revoke or grant permissions to individual applications post installation, including system software/applications, thus creating a level playing field where the user would decide what kind of access to provide to whom. That would be a clear demonstration, on the platform owners’ part, that they truly care about users’ privacy and not just creating barriers to entry to the competition and their bottom line.


» Independent companies

WSJ: Before Steve Jobs of Apple Inc. died, he approached you with a buyout offer. Why did you turn it away?

Mr. Ferdowsi: The problem that we’re trying to solve is a problem that only an independent company can solve. We want to let you use a Mac, or Windows PC, or iPad, or Android, without having to think about any of the technical details. It isn’t a problem any of those larger companies is going to be as inclined to solve in the same way we are.

A very very pertinent point, seeing that we’re experiencing a renaissance of massive, vertical closed systems, walled gardens and a childish desire to lock people into proprietary platforms that try to offer everything. Look at how Google, Facebook, Apple and now Microsoft are heavily promoting their respective ‘authentication’ platforms, playing the game of ignoring_the_competition. Facebook would certainly like you to use their APIs to authenticate your users, but they don’t have to try much because they have the most powerful database right now. Microsoft heavily promotes their ‘Microsoft Account’ (previously known by half a dozen names) and will do even more in Windows 8, while Apple makes ever increasing use of their Apple ID, across their products and services. Google, in lieu of their recent privacy terms update, needs no introduction I think with Google+ and every other service tied to a single Google account. The fact that Dropbox fully supports practically every single system platform I can think of using is reason enough for me to prefer it from competing services (Ubuntu One, Microsoft Skydrive, iCloud etc) and a refreshingly sane choice they made contrasted heavily by that of the established market leaders who fear of inadvertently promoting their competition.


» Break free, create your own walled garden.

It’s ironic, how ‘ease’ becomes the noose that chokes innovation and development. AOL, Facebook, iTunes, they all offer closed, proprietary solutions to ‘problems’ that — in more ways than one — are not so hard to solve. Solutions that seem to ‘work’, that ‘succeed’ because the ‘trend’ is to embrace ‘easy’, as opposed to ‘moderately challenging’, because the ‘smart money’ is behind them and because of network effects.

In the last few years, that is after the wave of ‘Web 2.0’ (ironically, yet another ‘trend’ exploited by ‘experts’ that abused it for profit) subsided, Facebook started making serious money. Its real success as an advertising platform is not only arguably minimal, but quite controversial. It took a long time for the advertising industry and the hordes of marketing monkeys to embrace Facebook’s walled garden approach and doing what they do best, counting. Only this time it wasn’t ‘impressions’ or ‘clicks’ or ‘conversions’ they were counting, but ‘likes’, another frivolous metric that doesn’t really mean anything in the real world. Facebook apps, once touted as the next big thing and a threat for the web, were stillborn, largely because Facebook itself made significant steps to expand beyond the confines of its site, by creating interfaces, programmatic and user, for other platform-owners to embed in or integrate with their platforms. So we got a slew of ‘social plugins’, more ‘APIs’, etc. But there were some exceptions, like Zynga, a gaming company living inside Facebook.

Now, Zynga just launched Zynga.com. And it’s a big deal, because this is the first Facebook-dependent business of significant scale that expands beyond the confines of this walled garden du jour.

The whole ‘frenzy’ with Facebook in the ad world is now in its third year. As with AOL’s endeavours fifteen years ago, the Facebook frenzy may be past its prime; as a teenager of the early-to-mid 1990s, AOL ‘keywords’ seemed to me like a pointless exercise, yet another ‘top-down’, force-fed business model that people never cared about.

Clearly people care about Facebook; they care about the platform that connects them to people they love: their friends and their relationships, news from their social circles, people they’d like to know better or simply keep in touch. They could hardly care less about Facebook pages, Facebook ads, the Facebook business. Sadly, marketers and advertisers, typically the last group to perceive change — and perhaps the most dependent on ‘convention’ (make no mistake, Facebook is convention, as is Google), will take a bit longer to ‘wake up’. That Zynga chose to move beyond Facebook is undoubtedly a wake up call and a sign of maturity in an industry that more than often adopts the strategy of others, instead of coming up with its own.


» Τουλάχιστον να γνωρίζουμε.

Πριν από περίπου ενάμιση μήνα ‘υποβαθμίστηκε’ η ταχύτητα της σύνδεσής μου στο σπίτι, για λόγους που μπορώ να αποδώσω μόνον στην ανικανότητα του ΟΤΕ. Παρ’ότι ενδιαφέρουσα περίπτωση που συνδυάζει τεχνική ανικανότητα και μια γερή δόση Κάφκα — δεν θα μπώ σε λεπτομέρειες (ζούμε άλλωστε μια ιδιαίτερα σουρρεαλιστική εποχή που κάνει ασήμαντη την εν λόγω προσωπική ιστορία), αποφάσισα να ψάξω λίγο online για παρόμοια προβλήματα, την θέση της ΕΕΤΤ για το χάλι των ευρυζωνικών συνδέσεων στην Ελλάδα κλπ.

Στο ψάξιμο βρήκα το εξής: Εν διαμέσου κρίσης, στα μέσα του καλοκαιριού που μας πέρασε ξεκίνησε την πιλοτική του λειτουργία το ΣΑΠΕΣ, το Σύστημα Αποτίμησης Ποιότητας Ευρυζωνικών Συνδέσεων της ΕΕΤΤ, το οποίο καταγράφει την ταχύτητα της ευρυζωνικής σας σύνδεσης και άπεικονίζει τα στοιχεία ως overlay σε χάρτη. Παρ’ότι τα αποτελέσματα είναι ακόμη σχετικά λίγα, η εικόνα είναι ενδιαφέρουσα και οι ‘μαύρες’ τρύπες, περιοχές με φοβερά κακή ποιότητα ευρυζωνικής σύνδεσης, πολλές.

Εαν δεν το γνωρίζετε ήδη, εγγραφείτε (είναι γρήγορο και σχεδόν ανώνυμο — χρειάζεται ένα email και την διεύθυνσή σας) και κάντε μια μέτρηση της ταχύτητας της σύνδεσής σας, ιδιαίτερα εάν αντιμετωπίζετε πρόβλημα με αυτή. Όσοι περισσότεροι συμμετάσχουν, τόσο περισσότερες πληροφορίες θα έχει η ΕΕΤΤ και ευελπιστώ πως αν υπάρξει καλή συμμετοχή ενδεχομένως να αποκτήσουμε καλύτερες συνδέσεις μια ώρα αρχύτερα.
