WhatsApp glitch paralyzes app for 4 hours: Oh dear. Just two days after Facebook made geeks everywhere green with its acquisition of WhatsApp for $19 billion, come Saturday night Israel time the mobile messaging company’s platform collapsed for four hours. If you were one of the company’s 430 million users, you couldn’t send or receive messages using its app. Users were reduced to infuriated tweets, during which WhatsApp confirmed that it was having server issues, but as of late Saturday night the app was back online. Some 54 billion messages are sent every day using WhatsApp, compared with 230 million tweets. The WhatsApp deal may show that Mark Zuckerberg sees the future in messaging, but not every messaging app is equal.

Zlango, goodbye: After a decade and $22 million, Israeli texting company Zlango is closing down, last week firing its last workers and vanishing from the Apple app store. Zlango, founded in 2004, had aimed to create a pictographic language for mobile – note that it began before the advent of smartphones, to which it had to adapt its technology. It raised money from major venture capital funds and local tech figures and found business partners, mainly in Asia, including Vodafone Hong Kong and India’s Bharti.

Broadcom makes communication chips for mobile devices, while Siliquent is into server networking technology, which is QLogic’s field.

State exits phone company once and for all: And thus an era ends, not with a bang but with a stock distribution of Bezeq shares by the state. Once Israel’s national phone company, now Bezeq is not a government company nor even a quasi-government one. Concerned about causing a jolt, last Wednesday the state holdings company, MI Holdings (which, by the way, stands for Medinat Israel Holdings), advised all Tel Aviv Stock Exchange clearers that it would be selling its 26.4 million Bezeq shares by 8 the next morning. The 0.93% stake had been worth about 152 million shekels ($43 million). Bezeq is now controlled by Shaul Elovitch’s B Communications.

Do you have to join the biometric database? No: Also last Wednesday, the court slapped the Interior Ministry and ordered it to advise the public that joining the biometric database is voluntary, not compulsory – at least during the pilot stage. No rights will be impaired by refusal to join. Now you know. Campaigns explaining about the biometric database had been, shall we say, unclear on that point, as Judge Miriam Naor pointed out.
