An update on how we tackle hacked spam

By Google Webmaster Central (noreply@blogger.com) on 2015-10-06

hacked sites, search results, webmaster guidelines

Recently we have started rolling out a series of algorithmic changes that aim to tackle hacked spam in our search results. A huge amount of legitimate sites are hacked by spammers and used to engage in abusive behavior, such as malware download, promotion of traffic to low quality sites, porn, and marketing of counterfeit goods or illegal pharmaceutical drugs, etc.

Website owners that don’t implement standard best practices for security can leave their websites vulnerable to being easily hacked. This can include government sites, universities, small business, company websites, restaurants, hobby organizations, conferences, etc. Spammers and cyber-criminals purposely seek out those sites and inject pages with malicious content in an attempt to gain rank and traffic in search engines.

We are aggressively targeting hacked spam in order to protect users and webmasters.

The algorithmic changes will eventually impact roughly 5% of queries, depending on the language. As we roll out the new algorithms, users might notice that for certain queries, only the most relevant results are shown, reducing the number of results shown:

Audio Testing - Automatic Gain Control

By Google Testing Bloggers (noreply@blogger.com) on 2015-10-08

Patrik Höglund, WebRTC

By: Patrik Höglund

What is Automatic Gain Control? 

It’s time to talk about advanced media quality tests again! As experienced Google testing blog readers know, when I write an article it’s usually about WebRTC, and the unusual testing solutions we build to test it. This article is no exception. Today we’re going to talk about Automatic Gain Control, or AGC. This is a feature that’s on by default for WebRTC applications, such as http://apprtc.appspot.com. It uses various means to adjust the microphone signal so your voice makes it loud and clear to the other side of the peer connection. For instance, it can attempt to adjust your microphone gain or try to amplify the signal digitally.

Figure 1. How Auto Gain Control works [code here].

This is an example of automatic control engineering (another example would be the classic PID controller) and happens in real time. Therefore, if you move closer to the mic while speaking, the AGC will notice the output stream is too loud, and reduce mic volume and/or digital gain. When you move further away, it tries to adapt up again. The fancy voice activity detector is there so we only amplify speech, and not, say, the microwave oven your spouse just started in the other room.

Downtime (rsync, mail)

By Florian Pritz on 2015-10-08

Update: All fixed now.

I just installed a kernel update on our rsync and mail server and it seems we have broken hardware so it is unable to reboot right now. Mailing lists are running on a different system however you need to use the lists.archlinux.org domain rather than archlinux.org. So for arch-general you'd use arch-general@lists.archlinux.org. Mails sent to the normal domain will go through once the server is up again.

The rsync master will stay unavailable for now.

I've asked the hoster to look into the issue, but I can't currently estimate when I'll get a reply/fix.

Columned Graphite Data in InfluxDB

On 2015-10-10

For a long time now graphite has been the defacto standard for use as a time-series database, recently I decided to try InfluxDB, this blog post is about what I've found.

Installation and configuration of InfluxDB is as about as simple as it can get:

27 languages to improve your Python

By Nick Coghlan on 2015-10-11

python

27 Languages

As a co-designer of one of the world's most popular programming languages, one of the more frustrating behaviours I regularly see (both in the Python community and in others) is influential people trying to tap into fears of "losing" to other open source communities as a motivating force for community contributions. (I'm occasionally guilty of this misbehaviour myself, which makes it even easier to spot when others are falling into the same trap).

While learning from the experiences of other programming language communities is a good thing, fear based approaches to motivating action are seriously problematic, as they encourage community members to see members of those other communities as enemies in a competition for contributor attention, rather than as potential allies in the larger challenge of advancing the state of the art in software development. It also has the effect of telling folks that enjoy those other languages that they're not welcome in a community that views them and their peers as "hostile competitors".
