Opera Presto Source Code Leaks Online (bleepingcomputer.com)

Posted by msmash on from the leak-leak-leak dept.

Catalin Cimpanu, writing for BleepingComputer: An unknown third-party has leaked the source code of the old Opera Presto browser engine on GitHub, and later on Bitbucket, two services for hosting and sharing source code online. Opera Presto is the layout engine at the heart of the old Opera browser. Opera Software used Presto between Opera 7 and Opera 14 and replaced Presto with Blink, Chrome's layout engine, in Opera 15, released in May 2013. Despite its removal from the company's main product, Opera engineers continued to use Opera Presto for the Opera Mini and Opera Mobile browsers. According to timestamps, the Opera Presto source code was first uploaded on GitHub but was taken down last Friday, on January 13, after Opera's lawyers filed a DMCA request.

      26 years in and around the military here...

      I hope you are being tongue-in-cheek. Whilst Russia's military is not, perhaps, on a par with the US military, she is no pushover. Russia has a weak navy, not a weak army or special ops community. Russia has a modern, phenomenal Air Force with planes that the west would dearly love to get a hold of. Look up the SU-34, SU-35, K-52. The new AK series of rifles are superior for ground combat than the M-4 and M-16 variants. I know this firsthand from serving in the military myself. I've used them. Russians build cruder, but very effective gear. Their gear is built with looser tolerances to allow for operating extremes, be this rifles or electronics. Their 1st generation night vision gear is still better than some western 3rd generation gear. A quick look into history will show you how well the Germans fared when they stepped into mother Russia expecting to route them. They got their asses handed to them by a group of rag tag conscript peasants in large part because Germany didn't understand how cold Russia gets. Moreover, they went in too deep and lost control of their supply lines.

      Russia is king in tank warfare. Still. Russia has a fairly large standing army that is well trained. Russia is like Afghanistan--she's never been invaded AND taken over. The Russians are a very resilient people and to say their military could be routed by a few overweight NGs shows the author knows nothing of the military whatsoever. California's GDP is larger than MOST countries, but GDP and projected force are two different animals. The US and Russia both have superior militaries, with the Chinese rapidly catching up in tech what they already have in numbers. Russia doesn't suffer the PC conscience the west has when it comes to warfare. They correctly see things as objectives and goals. I know many men who have served in the Russian Federation military as well as a few in the former Soviet military. They are not the pushovers you think.
