  1. Bakalım neler neler yapılabilir bununla. Ana amacı zararlı yazılımları incelemekmiş ama kaynak kod hırsızlığı vs. için de kullanılabilir diye düşünüyorum.

    THE NATIONAL SECURITY Agency develops advanced hacking tools in-house for both offense and defense—which you could probably guess even if some notable examples hadn't leaked in recent years. But on Tuesday at the RSA security conference in San Francisco, the agency demonstrated Ghidra, a refined internal tool that it has chosen to open source. And while NSA cybersecurity adviser Rob Joyce called the tool a "contribution to the nation’s cybersecurity community" in announcing it at RSA, it will no doubt be used far beyond the United States.

    You can't use Ghidra to hack devices; it's instead a reverse-engineering platform used to take "compiled," deployed software and "decompile" it. In other words, it transforms the ones and zeros that computers understand back into a human-readable structure, logic, and set of commands that reveal what the software you churn through it does. Reverse engineering is a crucial process for malware analysts and threat intelligence researchers, because it allows them to work backward from software they discover in the wild—like malware being used to carry out attacks—to understand how it works, what its capabilities are, and who wrote it or where it came from. Reverse engineering is also an important way for defenders to check their own code for weaknesses and confirm that it works as intended.

    "If you’ve done software reverse engineering, what you’ve found out is it’s both art and science; there’s not a hard path from the beginning to the end," Joyce said. "Ghidra is a software reverse-engineering tool built for our internal use at NSA. We're not claiming that this is the one that’s going to be replacing everything out there—it's not. But it helped us address some things in our workflow."

    Similar reverse-engineering products exist on the market, including a popular disassembler and debugger called IDA. But Joyce emphasized that the NSA has been developing Ghidra for years, with its own real-world priorities and needs in mind, which makes it a powerful and particularly usable tool. Products like IDA also cost money, whereas making Ghidra open source marks the first time that a tool of its caliber will be available for free—a major contribution in training the next generation of cybersecurity defenders. (Like other open source code, though, expect it to have some bugs.) Joyce also noted that the NSA views the release of Ghidra as a sort of recruiting strategy, making it easier for new hires to enter the NSA at a higher level or for cleared contractors to lend their expertise without needing to first come up to speed on the tool.

    The NSA announced Joyce’s RSA talk, and Ghidra’s imminent release, in early January. But knowledge of the tool was already public thanks to WikiLeaks’ March 2017 “Vault 7” disclosure, which discussed a number of hacking tools used by the CIA and repeatedly referenced Ghidra as a reverse-engineering tool created by the NSA. The actual code hadn’t seen the light of day, though, until Tuesday—all 1.2 million lines of it. Ghidra runs on Windows, MacOS, and Linux and has all the components security researchers would expect. But Joyce emphasized the tool's customizability. It is also designed to facilitate collaborative work among multiple people on the same reversing project—a concept that isn't as much of a priority in other platforms.

    Ghidra also has user-interface touches and features meant to make reversing as easy as possible, given how tedious and generally challenging it can be. Joyce's personal favorite? An undo/redo mechanism that allows users to try out theories about how the code they are analyzing may work, with an easy way to go back a few steps if the idea doesn't pan out.

    The NSA has made other code open source over the years, like its Security-Enhanced Linux and Security-Enhanced Android initiatives. But Ghidra seems to speak more directly to the discourse and tension at the heart of cybersecurity right now. By being free and readily available, it will likely proliferate and could inform both defense and offense in unforeseen ways. If it seems like releasing the tool could give malicious hackers an advantage in figuring out how to evade the NSA, though Dave Aitel, a former NSA researcher who is now chief security technology officer at the secure infrastructure firm Cyxtera, said that that isn't a concern.

    “Malware authors already know how to make it annoying to reverse their code,” Aitel said. “There’s really no downside” to releasing Ghidra.

    No matter what comes next for the NSA's powerful reversing tool, Joyce emphasized on Tuesday that it is an earnest contribution to the community of cybersecurity defenders—and that conspiracy theorists can rest easy. "There’s no backdoor in Ghidra," he said. "Come on, no backdoor. On the record. Scout's honor."

  2. 1803'den sonra mikrofonla alakalı sorun yaşamıştım. Bazen mikrofon kafasına göre çalışmıyordu. Daha sonraki güncellemeler ile sorun ortadan kalkmıştı diye hatırlıyorum. 

     

    Bir update'den sonra Windows dosya uzantılarına özel program seçimine izin vermiyordu ama güncellemeler ile çözüldü. 

     

    Daha öncede konusunu açtığım kısa süreli zırıltı sesi duyma olayı da güncellemeler ile çözüldü.

     

    Bunlar dışında sorun yaşamadım. Bence her sorunda format atılmamalı. Format yaptıktan sonra yazılımları kurmakla, sistemi konfigüre etmekle uğraşıyorum uzun süre. Hiç çekemem format felan.

    The latest builds of Windows insider indicate that Microsoft is working to unify the infrastructure of Windows 10 and the Xbox OS. This makes it possible to play Xbox console games on PCs with Windows 10, which has already been demonstrated with the survival action game State of Decay. 

     

    This is not a good development for PC Gaming as they could become console standardization running on the PC. By making this 'port' compatibility, basically, Microsoft seems to indicate that it would like to release console games on the PC. 

     

    Microsoft has not announced these changes just however in Windows 10 Preview Build 18334 the company implements a free version of State of Decay to download to report issues. When downloading this (trial) version, the game is no longer sourced from the Microsoft Store servers, but rather from the Xbox Live servers, which typically ship only pure Xbox titles. 

     

    The installation file obtained through this server uses the .xvc file format developed for the Xbox One but plays the normal game through PowerShell. The conclusion is obvious: The Xbox version of the Survival game is playing, not the PC version. Ergo, the games are emulated.

     

    So in the future, chances are that if you purchase a PC Game in the Windows Store, you might end up with an emulated XBox One version.

    Emülatör yardımıyla çalışacaksa o zaman ciddi performans kaybı olabilir.


  4. Vega 56'ın fiyatı düşürüldü. Türkiye'deki pazara ne zaman fiyat yansır bilmem.

    The AMD Radeon RX Vega 56 can now be bought for $279 US on Newegg as mentioned in a press release by AMD. It’s no surprise that the price cut comes just a few hours before NVIDIA is going to introduce their new GeForce GTX 1660 Ti graphics card at the same MSRP of $279 US.

  5. Oyunun geliştiricileri optimizasyon yapma özürlü galiba. Üstüne sağda solda tehdit ediyorlar milleti çıkarmayız Steam'e diye. Metro serisi güzel oyundur her açıdan. Ama şu fps'ye bak, tam rezalet. 5$'a düşerse alırım.


  6. Hocam sizi yanlış yönlendirmeyeyim ama bir iki noktayı dile getirmek isterim. Elinizdekinden çok daha iyi değilse değmeyebilir. Bu tip setlerin müziklerde verdiği ses kalitesi iyi olmuyor. Sonuçta 150 TL Türkiye için az para değil. Ama elinizdeki eskidiyse, sorun çıkarıyorsa ya da bunun kalite olarak altında ise alınır tabii. Reddit'e bakındım, kullananlar komforlu olduğunu söylemişler. Kalite açısından yorum bulamadım.

  7. BIOS ayarları spoiler içinde. Yük altındaki sıcaklıkları görebilirsiniz. Max'e dikkat etmeyin. Programı ilk çalıştırdığımda Kraken x62 tam randıman veremiyor dolayısıyla ilk başlarda sıcaklık 80lere zıplıyor. Yük altında en sıcak çekirdek 75 derece.

     

    Tam çözemediğim ufak sorunlar var:

     

    1.) Sadece Turboyu 5GHz'de çalışacak şekilde ayarladım ama işlemci sürekli 5GHz'de çalışıyor. Bununla uğraşıp düzeltmem lazım

    2.) Dynamic Vcore (DVID)'i ayarladığım zaman sistem stabilitesi bozuluyor. Belki bir şeyi eksik ya da yanlış yapıyorumdur. Tekrar bakmam lazım. Dolayısıyla sürekli 1.275v verecek şekilde ayalarladım BIOS'u.

  8. Hocam çok benzer sistemler kurmuşuz. Hayırlı olsun. Bende de 9900k var ve kullandığım anakart Z390 Aorus Master. Ben genellikle 4800MHz kullanıyordum fan sesi duymamak için ama sonra içim rahat etmedi vs 5 GHz'ye çıkardım.

     

    BIOS ayarlarını da paylaşırım hemen.


  9. Çok beklersiniz hehehehehehehehe :zuh:

    Despite PC gamers missing out on some high-profile console exclusives last year, the PC remains in the top slot for developers – and according to a recent survey, the PC’s lead is growing.

    The GDC State of the Game Industry survey is an annual study that asks current game developers about trends in the business. This year, the 4,000 survey respondents indicated yet again that the PC remains their favored platform for development, with mobile devices at a distant second. Consoles show up down the list from there.

    This year, 56% of respondents to the survey said that their last completed game shipped on PC, while 66% said the game they are currently working on will include a PC launch. That’s more than twice the number for either PlayStation 4 or Xbox One, and in both cases the PC improved slightly over last year’s results.
