Compiler & Interpreter

Compiler & Interpreter

Compilers and interpreters are used to convert the code of high level language into machine language. The high level program is known as source program and the corresponding machine level program is known as object program. Although both compilers and interpreters perform the same task but there is a difference in their working

Compiler

          A compiler searches all the errors of a program and lists them. If the program is error free then it converts the code of program into machine code and then the program can be executed by separate commands.

Interpreter

         An interpreter checks the errors of a program statement by statement. After checking one statement, it converts that statement into machine code and then executes that  statement. The process continues until the last statement of program occurs.

PUBG uses machine learning to look for cheaters

An update from the anti-cheat team reveals how the developer tackles cheats.

The anti-cheat team at PUBG Corp have posted an update on Steam that covers some of the work it's been doing over the last few months to stop cheat programs from disrupting the battle royale. While some specifics have to be avoided because revealing everything the team's up to could "harm progress", it provides a handy overview of the issues facing an online game like PUBG, along with some of the solutions that they've come up with. 

Along with third party anti-cheat programs like BattlEye and Uncheater, the team uses machine learning to study how people play, using that data to keep an eye out for things outside the norm that could suggest a hack's being used. Other companies have also been brought in to help improve PUBG's security. 

Blocking DLL injection attacks has also been a priority for the team, but some attempts to stop cheat programs from interfering with the game during development lead to things like Steam and Discord being misidentified as a threat.

A whopping 3TB of game logs are analysed by the team every day, apparently, along with more than 10 million reports. As well as keeping an eye on the game, PUBG Corp monitors the places that enable players to cheat. 100 people are employed to watch various websites and Discord groups.

The update also covers the results of legal action taken against people who sell these programs, listing around 250 arrests that were made in 2018 in China and South Korea. 

"Each game of PUBG sees up to 100 users trying to beat already incredible odds," PUBG Corp says. "We understand that even one person playing unfairly can severely impact the fun of so many people, and thus we need to maintain a much higher level of security than other games."

Hitman 2's first mission is now free for everyone !!!

Take a trip to the scenic shores of New Zealand, and then murder someone, in the Hitman 2 Starter Pack.

Phil declared in his review of Hitman 2 that it "feels safe": It doesn't depart from the formula established by the first game, but it delivers levels "that can rival some of the best in Hitman's long history." The first of them, Hawke's Bay, is set in a small beachfront property in New Zealand, and as of today it's free for everyone in a new Hitman 2 Starter Pack on Steam. 

The Starter Pack provides full access to all Hawke's Bay content, including challenges and unlocks, hidden stashes, new starting locations and weapons, and escalating difficulties. From March 8-17 it will also be the location of the fourth Hitman 2 Elusive Target, Dame Barbara Elizabeth Keating, aka "The Politician," a former Minister of Trade and Foreign Affairs for New Zealand who was busted siphoning charity funds into her offshore account.   

She was ultimately able to pin the blame on the charity's director and now she's working to restore her reputation and position—and thus it falls to Agent 47 to deliver a modicum of justice by, umm, airing her out. Owners of the Starter Pack will have the same opportunity to do the job as everyone else, under the same set of rules: You get one shot, and if you blow it, she gets away for good. (Or at least until Io Interactive brings her back around again.) 

It sure looks like Microsoft is testing Xbox One game support on Windows 10 PCs

Some interesting things are happening in Microsoft's Windows Insider program.

           

   

Game consoles have become more PC-like than ever, and that is especially true of the latest generation Xbox One. That doesn't mean you can play Xbox One games on your Windows system. Not yet, anyway. However, there is evidence to suggest that Microsoft is working towards that goal.

That evidence is found within Microsoft's Windows Insider program, in which participants are able to preview and test upcoming upgrades to Windows 10 before they are pushed out to the general populace. Recently, Microsoft has been asking Insiders to install and test of special edition of State of Decay, which it has made available for free.

"We’re excited to bring technology tailor-made for gaming to Windows. Help us validate these systems work as expected, and play State of Decay for free (limited time only!). Just tell us about any problems you encounter with installing and launching the game," Microsoft explained in a blog post.

That in and of itself is a hint that something is brewing, but digging deeper, there are some interesting tidbits that go along with it, as Brad Sams outlines on Thurrott.com. For example, the game does not download from the Microsoft Store server (serverdl.microsoft.com), and instead comes from assets1.xboxlive.com. Hmm.

It appears that Microsoft is pushing out the Xbox One version and not a PC port. Further evidence of this can be found in the .xvc file format the game uses. Microsoft introduced the .xvc file format in 2013 specifically for Xbox One games, and in this case, it can be installed using the updated PowerShell application in the Windows 10 19H1 test build.

Installing the game brings up a legacy DirectX setup prompt. The latest test build also installs a new Gaming Service app, Microsoft.GamingServices.app, with two accompanying drivers—xvdd.sys = XVD Disk Driver (Microsoft Gaming Filesystem Driver) and gameflt.sys = Gaming Filter (Microsoft Gaming Install Filter Driver).

Need further proof? Twitter user WalkingCat notes that the drivers contain references to Durango, which was the codename for the Xbox One.

What this ultimately means is that the next big update to Windows 10 could potentially introduce native support for Xbox One games. This could make it faster and easier for developers to push their console games to PC, though hopefully it doesn't lead to lazy experiences that fail to take advantage of what PCs can offer.
