Python Programming SDF record walkthrough In this essay I'll walk through the major parts of a simple V2000 SDFile record. Richard Apodaca summarized the SDfile format a few months ago, with details I won't cover here. You should read it for more background. Bear in mind that the variety of names for this format name leads to some confusion. It's often called an SDF file, which technically means structure-data file file, in the same way that PIN number technically means personal identification number number. I tend to write SD file, but the term in the documentation is SDFile.

I Want to Learn Programming but I Don’t Know Where to Start Software development is a challenging and lucrative career option. Our daily utility items — light bulbs, televisions, cars, banking, shopping — everything is driven by intelligent pieces of codes. If you want to learn programming but do not know where to start, you have come to the right blog. I have compiled a step-by-step guide that will get you started on your software development journey and eliminate your apprehensions.

Handling the SDF record delimiter In this essay I'll point out a common difficulty people have when trying to identify the end of an SDFile record.

Stack Abuse: Kernel Density Estimation in Python Using Scikit-Learn This article is an introduction to kernel density estimation using Python's machine learning library scikit-learn. Kernel density estimation (KDE) is a non-parametric method for estimating the probability density function of a given random variable. It is also referred to by its traditional name, the Parzen-Rosenblatt Window method, after its discoverers.

How to Create a Python Hello World Program There is a major difference between python 2 and python 3. For instance, one difference is the print statement. In python 2, the print statement is not a function. It is considered as a simple statement. Whenever we use the print statement in python 2, we do not use the parenthesis. On the other hand in python 3, print is a function and it is followed by the parenthesis. In any programming language, the simplest “Hello World” program is used to demonstrate the syntax of the programming language. In this article, we create the “Hello World” program in python 3. Spyder3 editor is used to creating and running the python script.

Mozilla: PGP in Thunderbird, Departures, Firefox Send and Firefox Notes Thunderbird implements PGP crypto feature requested 21 years ago Mozilla's mail reader Thunderbird has implemented a feature first requested 21 years ago. The somewhat garbled request – "I'd appreciate a plugin for PGP to ede and encrypt PGP crypted messages directly in Mozilla" [sic] – appears to have gone unimplemented due to concerns about US laws that bar export of encryption, debate about whether PGP was the right way to do crypto, and other matters besides. Thunderbird eventually chose to use Enigmail and its implementation of OpenPGP public key email encryption. However, it was an add-on rather than integrated. Commenters in the Bugzilla thread stemming from the request kept the dream of an integrated solution alive, though. Then in October 2019, the Thunderbird blog announced that Thunderbird 78 "will add built-in functionality for email encryption and digital signatures using the OpenPGP standard." Thunderbird 78 emerged in July 2020, and late in August Thunderbird contributor Kai Engert (:KaiE:) posted: "We have released support for OpenPGP email in Thunderbird version 78.2.1. Marking fixed."

Upcoming US Holidays (for Mike Taylor) This is my last full week at Mozilla, with my last day being Monday, September 21. It’s been just over 7 years since I joined (some of them were really great, and others were fine, I guess).

Update on Firefox Send and Firefox Notes As Mozilla tightens and refines its product focus in 2020, today we are announcing the end of life for two legacy services that grew out of the Firefox Test Pilot program: Firefox Send and Firefox Notes. Both services are being decommissioned and will no longer be a part of our product family. Details and timelines are discussed below. Firefox Send was a promising tool for encrypted file sharing. Send garnered good reach, a loyal audience, and real signs of value throughout its life. Unfortunately, some abusive users were beginning to use Send to ship malware and conduct spear phishing attacks. This summer we took Firefox Send offline to address this challenge. In the intervening period, as we weighed the cost of our overall portfolio and strategic focus, we made the decision not to relaunch the service. Because the service is already offline, no major changes in status are expected. You can read more here.

Mozilla Browser Extension to Track YouTube Recommendations It’s easy to get caught up in YouTube as it recommends an endless array of videos, with each one offering you more of the same type of content. But it’s not always the same content. Sometimes the process gets convoluted, and you wind up watching something you have no interest in. Mozilla is curious why this happens and created a browser extension to track YouTube recommendations.
