In software, we typically work with binary values. That is, we have arbitrary streams of bytes. To encode these arbitrary stream of bytes in standard formats like...Daniel Lemire From Daniel Lemire's Blog | May 2, 2020 at 03:28 PM
As we age, we tend to produce less of NAD+, an essential chemical compound for our bodies. We can restore youthful levels of NAD+ by using freely available supplements...Daniel Lemire From Daniel Lemire's Blog | May 2, 2020 at 12:18 PM
Sometimes wew need to compare strings in a case-insensitive manner. For example, you might want ‘abc’ and ‘ABC’ to be considered. It is a well-defined problem for...Daniel Lemire From Daniel Lemire's Blog | April 30, 2020 at 11:44 AM
Suppose that you have to sample a student at random in a school. However, you cannot go into a classroom and just pick a student. All you are allowed to do is to...Daniel Lemire From Daniel Lemire's Blog | April 26, 2020 at 05:54 PM
People’s muscles tends to become weaker with age, a process called sarcopenia. It appears that eating more fruits and vegetables is associated with far lower risks...Daniel Lemire From Daniel Lemire's Blog | April 25, 2020 at 10:46 AM
When dividing a numerator n by a divisor d, most programming languages round “down”. It means that 1/2 is 0. Mathematicians will insist that 1/2 and claim thatContinue...Daniel Lemire From Daniel Lemire's Blog | April 16, 2020 at 07:47 PM
Greenland sharks reach their sexual maturity when they are 150 years old and they live hundreds of years. Some living sharks today were born in the 16th century...Daniel Lemire From Daniel Lemire's Blog | April 11, 2020 at 12:35 PM
Most programming languages have integer types with arithmetic operations like multiplications, additions and so forth. Our main processors support 64-bit integers...Daniel Lemire From Daniel Lemire's Blog | April 5, 2020 at 04:54 PM
Antartica was once a rainforest. Google’s DeepMind built artificial intelligences that can defeat human beings at all of the standard Atari (arcade) games. The...Daniel Lemire From Daniel Lemire's Blog | April 4, 2020 at 10:40 AM
Last year (2019), we released the simjson library. It is a C++ library available under a liberal license (Apache) that can parse JSON documents very fast. How fast...Daniel Lemire From Daniel Lemire's Blog | March 31, 2020 at 06:20 PM
In a laboratory, we know how to turn any of our cells into youthful stem cells using something called the Yamanaka. If you expose cells to such factors for a short...Daniel Lemire From Daniel Lemire's Blog | March 28, 2020 at 10:00 AM
Memory is organized in cache lines, frequently blocks of 64 bytes. On Intel and AMD processors, you can store and load memory in blocks of various sizes, such as...Daniel Lemire From Daniel Lemire's Blog | March 17, 2020 at 09:47 PM
It is estimated that there are about 1080 atoms in the universe. The estimate for the total number of electrons is similar. It is a huge number and it far exceeds...Daniel Lemire From Daniel Lemire's Blog | March 15, 2020 at 01:50 PM
Mothers, but not fathers, possess gender-related implicit biases about emotion expression in children. Chinese researchers used to be offered cash rewards for publishing...Daniel Lemire From Daniel Lemire's Blog | March 14, 2020 at 12:37 PM
In our work parsing JSON documents as quickly as possible, we found that one of the most challenging problem is to parse numbers. That is, you want to take theContinue...Daniel Lemire From Daniel Lemire's Blog | March 9, 2020 at 09:36 PM
The benefits of flu vaccines in healthy adults is modest. They do not reduce neonatal death, hospitalisations, or working day lost. It does not seem more helpful...Daniel Lemire From Daniel Lemire's Blog | March 7, 2020 at 11:09 AM
In the C programming language, we typically manage memory manually. A typical heap allocation is a call to malloc followed by a call to free. In C++, you have more...Daniel Lemire From Daniel Lemire's Blog | March 3, 2020 at 03:41 PM
No one really understands how planes fly. This puts a dent in the model whereas inventions follows theory. Physician salaries and diagnostic tests account for 4...Daniel Lemire From Daniel Lemire's Blog | February 29, 2020 at 09:03 AM
Suppose that I give you a set of n objects and I ask you to pick k distinct objects, thus forming a new subset. How many such subsets are there? If you have taken...Daniel Lemire From Daniel Lemire's Blog | February 26, 2020 at 02:43 PM
In a large cohort study, the highest probability of reaching 90 years old was found for those drinking between 5g and 15 g of alcohol per day. This does not mean...Daniel Lemire From Daniel Lemire's Blog | February 22, 2020 at 11:36 AM
