On April 8, 2014, Microsoft officially discontinued support services for Windows XP. On April 8, 2014, the renowned open-source SSL support software OpenSSL exposed the "Heartbleed" vulnerability. Against this vulnerability, nearly all current IDS systems and firewalls are defenseless. SSL, fully known as Secure Socket Layer, is a widely used encryption protocol on the internet that prevents data from being eavesdropped during transmission between users and servers. OpenSSL is an open-source SSL support software. By invoking it, any software can easily implement SSL encrypted connections without needing to research SSL from scratch. The HTTPS protocol utilizes SSL to protect user data, and major websites redirect users to HTTPS pages during login to safeguard user information. However,...
Malaysia Airlines MH370 Disappearance: Canadian Pilot Proposes New Analysis
Today is March 27th, 19 days since the disappearance of MH370. With no progress in locating the aircraft, various theories about its fate have emerged. Both the mid-air disintegration and pilot hijacking hypotheses have flaws (the former has been ruled out). Recently, Canadian pilot Chris Goodfellow analyzed that the plane might have caught fire, causing communication system failure. The following content is quoted from Wikipedia: http://zh.wikipedia.org/wiki/%E9%A9%AC%E6%9D%A5%E8%A5%BF%E4%BA%9A%E8%88%AA%E7%A9%BA370%E5%8F%B7%E7%8F%AD%E6%9C%BA%E7%A9%BA%E9%9A%BE Canadian Class 1 pilot and instrument flight engineer Chris Goodfellow wrote an analytical article proposing a theory. He stated that Captain Zaharie's flight maneuvers, in his view,...
Divine Algorithm for Class Gossip
Saw this on Bilibili, av1020723 . I might create a PHP version later. The original program was in Java and wouldn't run on my computer (unknown reason). I translated the source code to Pascal.

The Legend of Class 63 — Summit of No.2 High School: Reverse Engineering and Easter Egg Hunt in the Demon Tower Game
These nights I've been attending chemistry Olympiad classes. During yesterday's session, our chemistry teacher invited several seniors to share their experiences. As they chatted, they mentioned a Demon Tower game they developed in their free time — "The Legend of Class 63: Summit of No.2 High School". Such an impressive game with Hangzhou No.2 High School elements naturally made me curious about its Easter eggs. Instead of playing through, reverse engineering seemed more efficient. The seniors mentioned using RPG Maker XP. Easy enough — downloaded it from http://xiazai.zol.com.cn/detail/43/426737.shtml Noticing the 9MB Game.rgssad file, I tried opening it with 7-Zip. No luck. The file properties revealed: Encrypted? Interesting....
The Dumbest Code Mistake: A Tragedy Caused by a Single Space
Bumblebee is an auxiliary tool for NVidia graphics cards on the Linux platform. It enables NVidia cards to utilize Optimus technology, allowing laptops to render with dedicated graphics while displaying through integrated graphics—essentially hardware-accelerated graphics switching. This is an extremely useful tool, but it once suffered a severe bug (though three years ago) where a single space caused the deletion of the /usr directory for a large number of Ubuntu users. It happened during a Git update, with changes in install.sh : @@ -37,7 +37,7 @@ # You should have received a copy of the GNU General Public License # along with bumblebee.

The Course Selection System Sucks
The school's course selection system opened at 12:00 for club sign-ups, using a snatching mechanism—limited spots, first-come-first-served. Having used this system before for elective courses, I logged in early (no courses were displayed yet). Starting at 11:59:30, I kept refreshing the page repeatedly, waiting for the courses to appear. At exactly 12:00, the courses popped up. I immediately clicked on my desired club. Instantly, a window flashed on the screen: "Registration failed! Schedule conflict!" Upon closer inspection: The club sessions were all scheduled for Monday and Tuesday's eighth period (though not actually at that time), while my previous electics occupied Monday/Tuesday/Thursday's seventh-eighth periods and Wednesday's fifth-sixth periods. Total conflict... Later,...
North Korean Samjiyon Tablet Ends Up on eBay Auction!
North Korea developed "independently researched" Android phones , and even created Samjiyon tablets targeting foreign tourists . Where there are products for sale, curious buyers will emerge. And where there are buyers, resellers follow after they've had their fun. On November 7, 2013, a North Korean Samjiyon tablet appeared on the renowned international auction site eBay, with a starting bid of $4.15. Reportedly, the auction account was Canadian with a shipping address in Yanji—right on the North Korean border. It's unclear whether a Canadian was temporarily staying in China after visiting North Korea, or if a Chinese resident used some unusual methods. Regardless of the seller's identity, this tablet—though slightly downgraded with a 1GHz CPU (originally 1.2GHz),...
【In My Lifetime】Typecho 0.9 Alpha Finally Released
Yesterday afternoon, I got home and opened Feedly, and saw an article about Typecho 0.9 on Jiang's Blog . What? Typecho actually updated in my lifetime!? I immediately opened the Typecho Official Website and saw that clean default theme of TE. I remember the official site didn't look like this before. The post started with just one sentence: "Yes, you haven't entered the wrong website. This simple place is indeed the official website of Typecho."... So I immediately downloaded, updated, and installed. The update method is simple: log in to FTP, delete the admin and var directories and index.php , upload these files from version 0.9, and then update the database in the backend. When I opened the login page, I instantly felt it was high-end, grand, and classy. It's said that TE 0....
