Stephen Wilhite, the inventor of the GIF, has died

Almost everyone has used an animated gif at least once on social networks and on their devices. Stephen Wilhite, inventor of this famous format, passed away a few days ago at the age of 74. Yet another victim of COVID-19. Today, GIFs (Graphics Interchange Format) are used in online conversations as memes and jokes, but in reality they have existed for decades and were born for very different reasons. Stephen Wilhite created the GIF in the late 1980s when he was employed at CompuServe, which is the beginning of the Internet age, with the aim of offering a format that would facilitate the download of color images at a time when speed of the Internet was completely different from the current one. Hence the .gif format has become one of the most popular on the web. Farewell to the inventor of the GIF format. “Humble, kind and good man” The unfortunate occasion allows to clarify the debate on the pronunciation of this acronym. As stated by the inventor Wilhite, the word “GIF” is pronounced with the soft G, or “JIF”. Stephen Wilhite has always remained a humble person and out of the spotlight. After retiring in the early 2000s, the inventor of the GIF image has spent his life traveling and building model trains in the basement of his home. “Even with all his achievements, he has remained a very humble, kind and good man,” his wife Kathaleen said in an interview with The Verge.

Bitcoin, mining contributes 0.08% of global CO2 emissions

CoinShares shared a new report in which it is estimated that Bitcoin’s mining activities emitted 42 million tons of carbon dioxide in the course of 2021. With global emissions of 49.36 billion tons of CO2, Bitcoin would therefore represent the source of 0.08% of total emissions. The CoinShares report comes at a time when the debate over Bitcoin’s energy consumption has heated up.

CoinShares data was collected using various estimates regarding the efficiency of the Bitcoin network, energy consumption, characteristics of the hardware used, all on a global scale. It is therefore possible that there is some discrepancy with the actual volume of CO2 emissions, but in any case the CoinShares estimate seems to coincide quite well with the sector data.

The report prepared by CoinShares also estimated the total electricity consumption at 89TWh, a value significantly lower than the Cambridge University estimates which are the most taken into consideration and which speak of an annual consumption exceeding 130TWh. In this case it would be 0.05% of the electricity consumed worldwide. According to data collected by CoinShares, 60% of Bitcoin’s mining business is powered by fossil fuels.

“Carbon emissions from the electricity suppliers that power the Bitcoin mining network are irrelevant in the grand scheme of things. With 0.08% of global CO2 emissions, remove the entire mining network from global demand,” and depriving hundreds of millions of people of their only hope for a fair and accessible form of money would amount to nothing more than a rounding error, ”CoinShares comments.

Just in recent days, a group of eight members of the US Congress coordinated by Senator Elizabeth Warren sent a letter to the six largest Bitcoin mining companies in the world with a request to disclose detailed data on their energy consumption. This is a move that underlines the growing regulatory pressure on mining activities in the United States in a context where miners themselves are trying to commit themselves more and more to using ever greater proportions of energy from renewable sources.

♬ Katy Perry ft Alesso – When I’M Gone

LYRIC

[Chorus]
When I’m gone, I’m never really gone
You think you’re movin’ on
But it won’t be for long, you’ll see
When I’m gone, I’m never really gone
You think you’re movin’ on
But no one’s gonna feel like, feel like

[Verse 1]
Thought it would be easy
Easy to forget me
Let go of the memories (Ah-ah-ah-ah)
Now your bed is empty
And you’re wakin’ up sweating
I’m still in your wild dreams

[Pre-Chorus]
Late nights, callin’ me, callin’ me
Do anything to keep me close
Well, you should know it’s gonna be, gonna be
So hard for you to let me go

[Chorus]
When I’m gonе, I’m never really gonе
You think you’re movin’ on
But it won’t be for long, you’ll see
When I’m gone, I’m never really gone
You think you’re movin’ on
But no one’s gonna feel like, feel like
[Post-Chorus]
Me on top of you
Touch you like I do
No, you’ll never forget
When I’m gone, I’m never really gone
You think you’re movin’ on
But no one’s gonna feel like, feel like

[Verse 2]
You’re chasin’ the danger
It’s just in your nature
Look for me in strangers (Ah-ah-ah-ah)
All these pretty faces
No one can replace it
I’m always your favorite

[Pre-Chorus]
Late nights, callin’ me, callin’ me
Do anything to keep me close
Well, you should know it’s gonna be, gonna be
So hard for you to let me go

[Chorus]
When I’m gone, I’m never really gone
You think you’re movin’ on
But it won’t be for long, you’ll see (When I’m gone)
When I’m gone, I’m never really gone (Never really gone)
You think you’re movin’ on
But no one’s gonna feel like, feel like (No one’s gonna feel like me)
[Post-Chorus]
Me on top of you
Touch you like I do
No, you’ll never forget
When I’m gone, I’m never really gone
You think you’re movin’ on
But no one’s gonna feel like, feel like
(Like me)

When I’m gone
When I’m gone

F1 Mercedes, Toto Wolff: “Lewis Hamilton was robbed of world title”

Toto Wolff, Mercedes team principal, spoke at the press conference to defend the work of the team and Lewis Hamilton. In fact, Mercedes has renounced any further appeal against the final result of the F1 2021 World Championship. The Austrian’s conference is full of strong sentences, which leave no appeal to different possibilities of interpretation. Among all, there is a phrase from Wolff that suggests the mood of him, Mercedes and Hamilton: “Lewis has been robbed of the 2021 World title”. The whole team has the utmost respect and recognition of Max Verstappen’s victory, but is deeply disappointed by the behavior of the Race Direction in the Abu Dhabi GP. In fact, criticisms of Michael Masi, defined as “incompetent and inadequate for the role he represents”, have been repeated.

NO APPEAL – «We decided not to appeal, despite being aware of our reasons. But we are also aware of the consequences of a possible appeal. I am sure we would have won in any courtroom, I am sure, in the light of the evidence at our disposal. But it is not in our style, and here we are not discussing how the FIA ​​or the Race Direction is structured: however, it is necessary to clarify how we will go forward, we need the certainty of precise, clear, equidistant rules that are applied continuously and unambiguously. Fourteen months ago, in the 2020 Eifel GP, a decision was taken opposite to that taken in the Abu Dhabi GP 2021: decision changed by 180 ° ».

SAFETY CAR – «The rules are clear. If there is a crashed car on the track and it takes time to remove it, red flags must be displayed. Furthermore, they should have split all the drivers, not just those between Hamilton, first, and Verstappen, second. For example, why not split even those ahead of Sainz, why deprive Ferrari of the chance to win? This is why I insist on the need for uniformly applied rules ».

MASI – «Masi the problem? I would say that the problem is much greater than Masi. It is not a question of individuals but of how decisions are made. We need a fair and continuous yardstick on how the rules are applied. I haven’t talked to Masi, why should I? A decision was simply made, in the last 4 minutes of the GP, which annihilated Hamilton. He took the title from him. Lewis dominated the race from the start, he would never have lost in that race situation, but there is no doubt that Hamilton was robbed of his victory. From every point of view: sporty, professional, human, he was robbed. So I believe that Masi’s role is incompatible with the type of decisions to be made; but I repeat, it is not a question of changing the Clerk of the Course, if anything it is necessary to change the decision-making system, clarity, continuity of application of the rules and fairness are fundamental ».

Log4Shell is the new zeroday flaw: a bug present in most applications, and very easily exploitable

Log4Shell is a new zeroday vulnerability discovered last Thursday when it was exploited to remotely compromise Minecraft servers. The vulnerability was traced with the code CVE-2021-44228 and was assigned a severity level of 10 out of 10 as it can be exploited very easily and allows the execution of remote unauthenticated code.

The vulnerability concerns in particular Log4j, an open source event logging tool based on Java and available from Apache that is used by hundreds of thousands of apps, especially in the cloud and including those commonly used in almost all companies on the planet. .

Event logging is a process by which applications keep an up-to-date list of the activities performed and which can thus be analyzed later in the event of errors. Almost all network security systems run some kind of event log, which gives libraries such as Log4j nearly endless coverage.

The exploitation of the vulnerability occurs by managing to have a special sequence of characters recorded on the log, as Cloudflare illustrated in detail in its analysis. And, as mentioned, the vulnerability can be exploited with ease: in the case of Minecraft, for example, it was possible to record the sequence of characters on the log simply by sending a message in the chat within the game.

Since the compromise of the Minecraft servers occurred, the security company Greynoise has detected an active scan in progress on the Internet that attempted to identify vulnerable servers. The researchers point out that they have observed that the vulnerability is exploited for various purposes: from the installation of malware to cryptomining, to the hardening of Linux botnets, passing from the extraction of data and configurations.

15th December (’21): Zamenhof Day

Zamenhof Day (EsperantoZamenhofa Tago, Polish: Dzień Zamenhofa), also called Esperanto Book Day, is celebrated on 15 December, the birthday of Esperanto creator L. L. Zamenhof.It is the most widely celebrated day in Esperanto culture. On this day, Esperantists hold information sessions and cultural gatherings to promote literature in Esperanto.

The history of celebrating Esperanto on Zamenhof’s birthday can be traced back to 17 December 1878, when at a birthday party for his 19th birthday he presented to his friends his Lingwe uniwersala, the first version of his international language. By 1887, this language had evolved into what is now recognized as Esperanto when he published the Unua Libro. 15 December previously used to be also known as Esperanto Day, but that is now celebrated on 26 July, the day Unua Libro was published.

15 December 2009 marked 150 years since Zamenhof’s birth, and there were several events to celebrate. On this date, the authorities in his home town of Białystok, Poland, opened a new Zamenhof Center, and a symposium honoring Zamenhof was held in New York City, featuring talks by Arika Okrent and Humphrey Tonkin among other professors.

Also on this date, the search engine Google, in 33 national language versions (but not the international English one), bore a special version of their logo (a Doodle) emblazoned with the Esperanto flag in honor of the occasion, which generated, on the 30 biggest Wikipedia languages, 1,750,000 page views on the articles “L. L. Zamenhof“.
