Puzzle loverGerald Selby has always loved riddles: where others saw only noise, he strove to find order and harmony. While working at Kellogg's Oatmeal Factory, he analyzed materials to increase shelf life. One day, while studying cereal from other companies, Jerry came across a strange sequence of characters on the back of a General Mills box. Instead of a date and a manufacturing factory, a mysterious code was printed there. Jerry decided to decipher it: taking several boxes of Kellogg's and General Mills breakfasts, he began to compare their moisture content, realizing that cereals with approximately the same moisture content should have close production dates. By making notes on paper, he identified some patterns. Soon he was able to decipher everything that made it possible to determine the place, date and time of manufacture. In a more aggressive line of business, “hacking” competitors' secrets could have been a huge benefit, but not in the production of oatmeal, so management was not enthusiastic about its discovery.
To increase the attractiveness of smartphones, manufacturers put as many different programs on them as possible. This is clear. Just take and delete the unnecessary ... Stop.
It turns out that some programs cannot be removed. For example, on selected Samsung models unable to delete Facebook (there is only the 'disable' option). They say that the Samsung S9 also comes with Microsoft's "non-removable" apps preinstalled.
These smartphones are for example. The same problem with other models. Many have non-removable programs from the manufacturer itself.
Since the early wars between Netscape and IE, functionality has become the main tool in browser competition. But the strategy of unlimited growth and expansion is completely insane. For too long we have let it go on.
Using wget I downloaded all 1217 of the W3C specifications published to date1. A significant portion of these must be implemented in the browser for the modern web to work. I have calculated the scope of these specifications. How complex do you think the modern web is?
Estimates have completely broken away from fundamental analysis, multiples are at historic highs, the rate of issue of securities is off the charts - and all this is accompanied by insanely speculative behavior of investors. A big crisis is inevitable. I want to start my story with the seemingly obvious, but today not everyone understands why the actions appeared. So, a share is a share in a company. Why do you need a share in a company? In order to have some of her profits. That is why the real value of a share is determined by the current and future profit of the issuing company, which is transferred to the shareholder in the form of dividends. Some companies pay dividends on a quarterly basis, others annually, and there are those that have not shared their net profit with their shareholders for more than a decade. At the end of the last century, this was a rarity, but with the advent of the Internet, the speed of business scaling increased by an order of magnitude, and technology companies made it a rule to reinvest all net profit in development so that in the future dividends would be even greater. Again, the value of any stock is provided only by its real or potential dividend yield. However, the value is not equal to the value and the actual price of a share is always speculative.
A couple of days ago this tweet caught my eye:

In short: once again, in C ++, they found some kind of crap that appeared there on its own, emergent-convergently, like the slime from a short science fiction story I read as a child, which accidentally appeared in the city sewer and grew to a universal organic solvent.
Let's figure it out, since it won't be long (according to the text of the Standard, I jumped no more than a couple of hours). And fun, referencing the Standard is always fun.
Back in the old days, when Google (or any of its poorly tuned AIs) wanted to kill your business, it usually denied you access to some of its services, and it worked. You've probably heard horror stories: Websites disappear from Google search and go into oblivion YouTube videos are demonetized , and creators lose a source of income Android applications disappear from Google Play and cannot contact their users APIs become more expensive or simply out of date Last but not least less important, personal analogue to all of the above: people lose access to their Gmail accounts and their entire digital life I swear I read the FAQ!
The past year turned out to be difficult, but nonetheless rich in fundamental discoveries and technological breakthroughs. Today we will talk about the most memorable results. Credit: scitechdaily.com
Apple has filed a patent for a charging cable that does not break at the connector thanks to the use of materials of varying hardness in the protective layer, according to the website of the US Patent and Trademark Office.
Apple admits that bending the cable near the connector causes unnecessary stress in the wire connection, causing the cable to fail. To prevent this, the company has developed a special design, which provides for the presence of a sleeve in the cable sheath, consisting of three layers of different stiffness. In the patent application,
Everyone is discussing an insanely beautiful story about how the guys from Reddit were able to defeat arrogant hedge funds, but not everyone understands what exactly happened in the markets. In this article, I explain in simple terms what exactly led to the current situation.
What Happened: Roaring Kitty Attacks!GameStop is an international video game store chain that is going through a hard time. Low profitability and unclear future prospects (who would even go to the store for something that you can just download from Steam?) Led to the fact that the company's shares fell from $ 55 in 2013 to $ 4 by mid-2020. Several large hedge funds were convinced. that the fall in GameStop stock prices will continue: as the professionals say, they "short-cut" these shares by a large amount.
Radare2 is a binary analysis framework. It includes a large number of utilities. Initially, it developed as a hexadecimal editor for searching and recovering data, then it acquired functionality and has now become a powerful data analysis framework. In this article I will tell you how to analyze the logic of the program using the Radare2 framework, and also describe the main elements of the assembly language that are necessary for reverse engineering.
