An anonymous reader writes: Wladimir Palant is the creator of the Adblock Plus browser extension, but he often gets asked how it compares to a similar extension for Chrome called Adblock. In the past, he's told people the two extensions achieve largely the same end, but in slightly different ways. However, recent changes to the Adblock project have him worried. "AdBlock covertly moved from an open development model towards hiding changes from its users. Users were neither informed about that decision nor the reasons behind it." He goes through the changelog and highlights some updates that call into question the integrity of Adblock. For example, from an update on June 6th: "Calling home functionality has been extended. It now sends user's locale in addition to the unique user ID, AdBlock version, operating system and whether Google Search ads are being allowed. Also, AdBlock will tell getadblock.com (or any other website if asked nicely) whether AdBlock has just been installed or has been used for a while — again, in addition to the unique user ID." Of course, Palant has skin in this game, and Adblock Plus has dealt with fallout from their "acceptable ads policy," but at least it's still developed in the open.

An anonymous reader writes "There is a lot of advice about backing up data, but it seems to boil down to distributing it to several places (other local or network drives, off-site drives, in the cloud, etc.). We have hundreds of thousands of family pictures and videos we're trying to save using this advice. But in some sparse searching of our archives, we're seeing bitrot destroying our memories. With the quantity of data (~2 TB at present), it's not really practical for us to examine every one of these periodically so we can manually restore them from a different copy. We'd love it if the filesystem could detect this and try correcting first, and if it couldn't correct the problem, it could trigger the restoration. But that only seems to be an option for RAID type systems, where the drives are colocated. Is there a combination of tools that can automatically detect these failures and restore the data from other remote copies without us having to manually examine each image/video and restore them by hand? (It might also be reasonable to ask for the ability to detect a backup drive with enough errors that it needs replacing altogether.)"

An anonymous reader writes "Within a few months of launching, Snapchat has made an enormous and lasting impact on the culture of communication on the Internet – and we should all be grateful. They have simplified a security process enough to the point that anybody can use it, while validating the market of the next generation of privacy-preserving ephemeral communication. Most importantly, we may finally get a break from the forced permanence of the Facebook and Google world, where everything you do and share is a data point to be monetized and re-sold to the highest bidder."

AleX122 writes "I have an idea for a web app. Things I know: I am not the first person with a brilliant idea. Many others 'inventors' failed and it may happen to me, but without trying the outcome will always be failure. That said, the project will be huge if successful. However, I currently do not have money needed to hire developers. I have pretty solid experience in Java, GWT, HTML, Hibernate/Eclipselink, SQL/PLSQL/Oracle. The downside is project nature. All applications I've developed to date were hosted on single server or in small cluster (2 tomcats with fail-over). The application, if I succeed, will have to serve thousands of users simultaneously. The userbase will come from all over the world. (Consider infrastructure requirements similar to a social network.) My questions: What technologies should I use now to ensure easy scaling for a future traffic increase? I need distributed processing and data storage. I would like to stick to open standards, so Google App Engine or a similar proprietary cloud solution isn't acceptable. Since I do not have the resources to hire a team of developers and I will be the first coder, it would be nice if technology used is Java related. However, when you have a hammer, everything looks like a nail, so I am open to technologies unrelated to Java."

Starting in September bidders won't be able to snipe curses, spells, or potions on eBay anymore. The company has decided to ban the sale of magic and magic items. “EBay regularly reviews categories and updates our policies based on customer feedback,” a statement from the company read. “We are discontinuing a small number of categories within the larger metaphysical subcategory, as buyers and sellers have told us that transactions in these categories often result in issues that can be difficult to resolve.”

Nerval's Lobster writes "For the past 40-some years, relational databases have ruled the data world. Relational models first appeared in the early 1970s thanks to the research of computer science pioneers such as E.F. Codd. Early versions of SQL-like languages were also developed in the early 70s, with modern SQL appearing in the late 1970s, and becoming popular by the mid-1980s. For the past couple of years, the Internets have been filled with heated arguments regarding SQL vs NoSQL. But is the fight even legitimate? NoSQL databases have grown up a bit (and some, such as Google's BigTable, are now mature) and prove themselves worthy. And yet the fight continues. Tech writer (and programmer) Jeff Cogswell examines both sides from a programming perspective."

mikejuk writes "Two former Facebook developers have created a new database that they say is the world's fastest and it is MySQL compatible. According to Eric Frenkiel and Nikita Shamgunov, MemSQL, the database they have developed over the past year, is thirty times faster than conventional disk-based databases. MemSQL has put together a video showing MySQL versus MemSQL carrying out a sequence of queries, in which MySQL performs at around 3,500 queries per second, while MemSQL achieves around 80,000 queries per second. The documentation says that MemSQL writes back to disk/SSD as soon as the transaction is acknowledged in memory, and that using a combination of write-ahead logging and snapshotting ensures your data is secure. There is a free version but so far how much a full version will cost isn't given." (See also this article at SlashBI.)

MrSeb writes "Mozilla has officially released Firefox 13. Unlike Firefox 12 (or 11, or 10, or indeed many of the recent Firefox versions), Firefox 13 is an important release with a handful of much-needed features that are long overdue. There's a new New Tab Page launcher, with your favorite and most-used websites, and a new default home page with one-click access to Bookmarks, Settings, Add-ons, etc. SPDY is on by default, too, which should help ameliorate the perceived speed difference between Chrome and Firefox. Finally, the developer tools (Page Inspector, Style Inspector, etc.) have been tweaked and updated!"

itwbennett writes "Sauce Labs had outgrown CouchDB and too much unplanned downtime made them switch to MySQL. With 20-20 hindsight they wrote about their CouchDB experience. But Sauce certainly isn't the first organization to switch databases. Back in 2009, Till Klampaeckel wrote a series of blog posts about moving in the opposite direction — from MySQL to CouchDB. Klampaeckel said the decision was about 'using the right tool for the job.' But the real story may be that programmers are never satisfied with the tool they have." Of course, then they say things like: "We have a TEXT column on all our tables that holds JSON, which our model layer silently treats the same as real columns for most purposes. The idea is the same as Rails' ActiveRecord::Store. It’s not super well integrated with MySQL's feature set — MySQL can’t really operate on those JSON fields at all — but it’s still a great idea that gets us close to the joy of schemaless DBs."

a_hanso writes "Hard drives that combine a traditional spinning platter for mass storage and solid state flash memory for frequently accessed data have always been an interesting concept. They may be slower than SSDs, but not by much, and they are a lot cheaper gigabyte-for-gigabyte. CNET's Harry McCracken speculates on how soon such drives may become mainstream: 'So why would the new Momentus be more of a mainstream hit than its predecessor? Seagate says that it's 70 percent faster than its earlier hybrid drive and three times quicker than a garden-variety, non-hybrid disk. Its benchmarks for cold boots and application launches show the new drive to be just a few seconds slower than a SSD. Or, in some cases, a few seconds faster. In the end, hybrid drives are compromises, neither as cheap as ordinary drives — you can get a conventional 750GB Momentus for about $150 — nor as fast and energy-efficient as SSDs.'"

trawg writes "A small Australian software company — backed by almost AUD$2 million in government assistance — is claiming they've developed a new technology which is '100,000 times better' for computer game graphics. It's not clear what exactly is getting multiplied, but they apparently 'make everything out of tiny little atoms instead of flat panels.' They've posted a video to YouTube which shows their new tech, which is apparently running at 20 FPS in software. It's (very) light on the technical details, and extraordinary claims require extraordinary evidence, but they say an SDK is due in a few months — so stay tuned for more." John Carmack had this to say about the company's claims: "No chance of a game on current gen systems, but maybe several years from now. Production issues will be challenging."

While it isn't as cool as carving his name on the surface of the moon with a giant heat ray, Hamad Bin Hamdan Al Ahyan's enormous signature is quite an accomplishment nonetheless. Measuring 1,000 meters high and two miles long, the sheiks name is now visible from space. From the article: "And rather than allow the writing to be washed away by the ocean, the letters actually form waterways that absorb the encroaching tide.The ruler's name is even visible on Google's map service. Hamad dreamed up the idea and had his workmen toil for weeks to craft the enormous piece of sand graffiti. It is not known how much it cost to make."

Hugh Pickens writes "As we celebrate America's birthday today, head over the to the NY Times and take a look at a very clever 'op-art' creation, 'Like it or Unfriend It' by Teddy Wayne, Mike Sacks, and Thomas Ng, that represents what 'America's Wall' would look like through our history. Beginning with 'Christopher Columbus wrote on America's wall: 'This IS India, right?,' through 'America added Great Britain to Kingdoms I am Fighting With,' through 'The South has changed its privacy settings to accept carpetbaggers,' and finishing with 'America stopped playing the game Wild-Goose Chase While Nation-Building,' and 'America has joined the China Network' the wall includes dozens of invitations, likes, posts and changes to privacy settings that shows a summary of American history as seen from a Facebook perspective. Our favorite from the 1980s: 'Ronald Reagan created a page: "Trickle-Down Economics" followed by "Half a million upper-income people like this.'"

Vrtigo1 writes "With many ISPs either already using bandwidth caps or talking about them, I was wondering how other Slashdot readers are keeping tabs on how much data is being transferred through their home Internet connections. None of the consumer routers I've used seem to make this information easily accessible. I'd like some way to see exactly how much data has been sent and received by the WAN port facing my ISP's modem so I can compare the numbers I get with the numbers they give me. I don't want to pay for their modem firmware updates and other network management traffic, so I'd like to see how the two numbers line up."

theodp writes "Some artists work in oils, some in pastels, some in acrylics. Photographer Jamie Beck and motion graphics artist Kevin Burg? Their medium of choice is animated GIFs. 'We wanted to tell more of a story than a single still frame photograph but didn't want the high maintenance aspect of a video,' said the two of their unusual collaboration. Needless to say, these are not your father's GeoCities 'Under Construction' GIFs — it can take several hours of manual editing for Beck and Burg to breathe the whisper of life into each image."
