SquidGuard
SquidGuard is a URL redirector used to use blacklists with the proxysoftware Squid. There are two big advantages to squidguard: it is fast and it is free. SquidGuard is published under GNU Public License.

Welcome to Hive!
Hive is a data warehouse system for Hadoop that facilitates easy data summarization, ad-hoc queries, and the analysis of large datasets stored in Hadoop compatible file systems. Hive provides a mechanism to project structure onto this data and query the data using a SQL-like language called HiveQL. At the same time this language also allows traditional map/reduce programmers to plug in their custom mappers and reducers when it is inconvenient or inefficient to express this logic in HiveQL

Cloud storage: a pricing and feature guide for consumers
Cloud storage services are cropping up left and right, all enticing their customers with a few gigabytes of storage that sync seemingly anywhere, with any device. We’ve collected some details on the most popular services, including Google Drive, to compare them.

I don’t normally post images here but this chart makes for a quick reference. The linked to article has much more details and worth a read.
What intrigued me about this is the max file size. This is probably set to keep people from building their own file containers (i.e. tar, zip, etc.) — which is what I hoped to do. Dropbox allows for a max file size of 300MB, ICloud 25MB. By building your own file containers gives you more local control over security of said files by allowing you to use your own encryption. 300MB seems suitable for even rather large databases. Apps will have to be more frugal with a 25MB limit. I need to start using my Dropbox account. Will report more on this later.
The technologist’s guide to troubleshooting hardware
PCs are always getting simpler and more streamlined, but there are still a lot of different parts to most of them, which means that there is a lot more that can go wrong with them. We’ll go through potential problems component by component, matching symptoms to issues and telling you the best way to inform your friend on the other end of the phone. Pay attention here, because many of these symptoms and procedures are also going to be useful when troubleshooting Macs, phones, and tablets.

A Faster Fourier Transform
The principle of the Fourier transform, which dates back to the 19th century, is that any signal, such as a sound recording, can be represented as the sum of a collection of sine and cosine waves with different frequencies and amplitudes. This collection of waves can then be manipulated with relative ease—for example, allowing a recording to be compressed or noise to be suppressed. In the mid-1960s, a computer-friendly algorithm called the fast Fourier transform (FFT) was developed. Anyone who’s marveled at the tiny size of an MP3 file compared with the same recording in an uncompressed form has seen the power of the FFT at work.

A faster transform means that less computer power is required to process a given amount of information—a boon to energy-conscious mobile multimedia devices such as smart phones.
Note the higlighted statement. Power consumption is trumping speed in modern computing devices. Also Note: The author of the linked to article isn’t me.
Ebooks Made of YouTube Comments Invade Amazon Kindle Store
A pair of artist-coders have unleashed a small army of bots designed to flood the Kindle e-book store with texts comprised entirely of YouTube comments. According to the artists, even they have no idea how many books their autonomous bots are posting to the store.

“The KINDLE’VOKE machinary is based on three major parts. (1) The “Sucker” a clever suction apparatus to gather comments from Youtube. (2) the “Ghost Writer’s Table”: the book compiler that handles generation of books content, book covers, authors at the same time. (3) The “Amazon Kindle Scatter Bots” that make the brand new digital literature available for all of us.
AMD Licenses ARM Technology: AMD Leans on ARM for Security
Last year after that particular AFDS, there was much speculation that AMD and ARM would get a whole lot closer. Today we have confirmed that in two ways. The first is that AMD and ARM are founding members of the HSA Foundation. This endeavor is a rather ambitious project that looks to make it much easier for programmers to access the full computer power of a CPU/GPU combo, or as AMD likes to call them, the APU. The second confirmation is one that has been theorized for quite some time, but few people have actually hit upon the actual implementation. This second confirmation is that AMD is licensing ARM cores and actually integrating them into their x86 based APUs.

MacBook Pro with Retina Display Teardown
Laptops are expensive. It’s critical that consumers have the option to repair things that go wrong, as well as upgrade their own hardware to keep it relevant as new technologies roll out. On top of being glued together, the new MacBook Pro is virtually non-upgradeable—making it the first MacBook Pro that will be unable to adapt to future advances in memory and storage technology.
“Defensive Patent License” created to protect innovators from trolls
The pledge might help Twitter attract ethical engineers, but ultimately it’s just one company taking a stand among a sea of litigators that are happy to prevent the sale of competitors’ products or extract licensing fees. A potentially more ambitious project called the “Defensive Patent License” aims to take the same basic idea practiced by Twitter and spread it across a big part of the technology industry.
via “Defensive Patent License” created to protect innovators from trolls | Ars Technica.
The commitment is both daunting in that it requires submitting all of a member company’s patents to the pool, and forgiving in that members can still sue the pants off non-members. Schultz said his team thought long and hard about the exact implementation of the Defensive Patent License.
