Geek-themed Meme of the Week: biometric been there

Continuing what should be but hasn’t been our weekly series highlighting the better tech-related memes … Reddit Having used the thumbprint reader on my iPhone for some time now, it has become a habit of the muscle-memory variety, meaning that I quite regularly have unlocked my phone before I have completed reading an alert that had caught my attention. So, too, a user of Reddit who submitted the above meme.I am guessing that there’s probably an easy solution. But since this certainly must be among the most First World of First World Problems ever encountered, I’ve yet to invest the time to search it out.

The curious case of slow downloads

Some time ago we discovered that certain very slow downloads were getting abruptly terminated and began investigating whether that was a client (i.e. web browser) or server (i.e. us) problem.

Some users were unable to download a binary file a few megabytes in length. The story was simple—the download connection was abruptly terminated even though the file was in the process of being downloaded. After a brief investigation we confirmed the problem: somewhere in our stack there was a bug.

Describing the problem was simple, reproducing the problem was easy with a single curl command, but fixing it took surprising amount of effort.

In this article I'll describe the symptoms we saw, how we reproduced it and how we fixed it. Hopefully, by sharing our experiences we will save others from the tedious debugging we went through.

After a fruitful session with tcpdump one of our engineers was able to prepare a test case that reproduced the Continue reading

Support for SQL Server 2005 ends Tuesday – are you ready?

Tuesday marks the end of support for Microsoft SQL Server 2005, and that means companies relying on it are just about out of time. There will be no more updates from Microsoft, so staying with the software could open you up to a host of risks.Microsoft encourages users to move to SQL Server 2014 or Azure SQL Database, but those aren't the only options. Either way, the transition is going to take some time. If you haven't already been working on it, the most important thing now is to act quickly to minimize the amount of time your company is left exposed.To read this article in full or to leave a comment, please click here

SSD shootout: PCI Express blows away SATA and M.2 in throughput testing

For the better part of a decade now, the traditional interface for hard drives has been Serial ATA (SATA). With the advent of the solid state drive (SSD), new interfaces have come into play designed to speed up throughput, because the SATA interface has rapidly become the bottleneck in drive speed.To read this article in full or to leave a comment, please click here(Insider Story)

iPhone 7 Rumor Rollup: No more swearing; Plus-size exclusive; new design concept

Now that Apple is officially in its 40s, you might think the company would settle down a bit and douse all those silly rumors about iPhone 7 smartphones and so forth. But no, it looks like the Apple rumor mill isn’t hitting any sort of midlife crisis.Exclusive to 5.5-inch iPhone 7 Plus? Fretting has already begun, and now has intensified, that the much anticipated dual-lens camera Apple is believed to be working on will only be available in the 5.5-inch iPhone 7 Plus model. And not everyone wants to lug around such a big iOS device (isn’t that part of the reason so many have ditched their portable digital cameras and just use their smartphones for picture taking now?).To read this article in full or to leave a comment, please click here

Sonic Pi: Realtime music creation for the Raspberry Pi (and more)

In my last post I discussed a Web-based programming environment for the Raspberry Pi. Today, for your further Raspberry Pi delectation, I have another RPi-compatible programming tool but this it’s rather more specific: It’s called Sonic Pi and it’s for programming music in real time.Created by Sam Aaron at the University of Cambridge Computer Laboratory, Sonic Pi is a free, open source, live coding synthesizer released under the MIT License. Better still, it not only runs on the Raspberry Pi as its name suggests, it also runs on Windows, Linux, and OS X.To read this article in full or to leave a comment, please click here

Devil is the details: Dirty little secrets of the Internet of Things

Where is IoT going in the long run?... To cash in on the treasure trove of “everything it knows about you,” data collected over the long term, at least it is according to a post on Medium about the “dirty little secret” of the Internet of Things.A company can only sell so many devices, but still needs to make money, so the article suggests the “sinister” reason why companies “want to internet-connect your entire house” is to collect every little bit of data about you and turn it into profit. Although the post was likely inspired in part by the continued fallout of Nest’s decision to brick Revolv hubs, there could a IoT company eventually looking for a way to monetize on “if you listen to music while having sex.”To read this article in full or to leave a comment, please click here
