Concepts, Stroustrup believes, will greatly ease engineers' ability to write efficient, reliable C++ code... The most obvious effect will be a massive improvement in the quality of error messages, but the most important long-term effect will be found in the flexibility and clarity of code, Stroustrup says. "In particular, having well-specified interfaces allows for simple, general and zero-overhead overloading of templates. That simplifies much generic code"
Concepts are already available in GNU C Compiler 6.2, and Stroustrup wants them to be included in C++ 20. "In my opinion, concepts should have been part of C++ 17, but the committee couldn't reach consensus on that."
Two security researchers are tracking the attacks on Google spreadsheets, and report that when a ransom is paid, many victims still report that their data is never restored. But the researchers also identified 124 Hadoop servers where the attacker simply replaced all the tables with a data entry named NODATA4U_SECUREYOURSHIT. "What's strange about these attacks is that the threat actor isn't asking for a ransom demand," reports Bleeping Computer. "Instead, he's just deleting data from Hadoop servers that have left their web-based admin panel open to remote connections on the Internet."
The issue also took the site offline, temporarily making the work of 16 million K-12 students who have used the nonprofit's Code Studio disappear. "On the plus side, this new table will be able to store student coding information for millions of years," explains the site's CTO. But besides Friday's missing saves, "On the down side, until we've moved everything over to the new table, some students' code from before today may temporarily not appear, so please be patient with us as we fix it."
You can have a sneak preview by looking at the current draft of pre-fascicle 5a (52 pages), last updated 18 January 2017. As usual, rewards will be given to whoever is first to find and report errors or to make valuable suggestions. I'm particularly interested in receiving feedback about the exercises (of which there are 125) and their answers (of which there are 125).
Over the years Knuth gave out over $20,000 in rewards, though most people didn't cash his highly-coveted "hexadecimal checks", and in 2008 Knuth switched to honorary "hexadecimal certificates". In 2014 Knuth complained about the "dumbing down" of computer science history, and his standards remain high. In his most-recent update, 79-year-old Knuth reminds readers that "There's stuff in here that isn't in Wikipedia yet!"
Oracle removed MD5 as a default code signing option from Java SE 6, released in 2006. Despite this, there will be thousands of Java apps that will never be resigned. For this, Oracle will allow system administrators to set up custom deployment rule sets and exception site lists to allow Java applets and Java Web Start applications signed with MD5 to run. Sometimes in the second half of 2017, Oracle also plans to change the minimum key length for Diffie-Hellman algorithms to 1024 bits. These updates are part of Oracle's long-standing plan for changes to the security algorithms in the Oracle Java Runtime Environment and Java SE Development Kit.
There's an improved output system in the newest release, and both its compiler and library are MIT licensed. Share your thoughts and opinions in the comments. Is anybody excited about writing code in Nim?
There's a a 16-chapter book about the language on GitHub.
" No patient, consumer, or client data was ever extracted or viewed," the company's data directory has said. "The forensic analysis proves that. The data was encrypted -- so it couldn't have been viewed -- and it was never extracted, so nobody has it and could attempt decryption." They're saying it was a "targeted" attack meant to corrupt the data rather than retrieve it, and they're "reconstructing historical data" from backups, though their web site adds that their backup sites were also targeted.
"In response to this attack, all client sites have been migrated to a new, more secure environment," the company's CEO announced on YouTube Saturday, adding that "Keeping our client's data secure has always been our top priority." Last week one industry publication had reported that the outage "has sent 1,000 marijuana retailers in 23 states scrambling to handle everything from sales and inventory management to regulatory compliance issues."
For now, most of the people reading this probably have a decent desktop that can compile and run code, but that's slowly changing. Fewer people have the opportunity to write code and share it. For all of the talk about the need to teach the next generation to program, there are fewer practical vectors for open code to be distributed.
So that is my question: Where on the internet can one best go to request that a new open source software tool that does not exist yet be developed? Or do open source tools only come into existence when someone -- a coder -- starts to build a software, opens the source, and invites other coders to join the fray?
This is a good place to discuss the general logistics of new open source projects -- so leave your best answers in the comments. What's the best place to suggest new open source software?
- "At over 350,000 packages, the npm registry contains more than double the next most populated package registry (which is the Apache Maven repository). In fact, it is currently the largest package registry in the world."
- In the preceding four weeks, users installed 18 billion packages.
- This translates into 6 billion downloads, "because approximately 66 percent of the installs are now being served from the cache."
- ping.npmjs.com "shows that the registry's services offer a 99.999 uptime."
- Every week roughly 160 people publish their first package in the registry
But what about the incident last year where a developer suddenly pulled all their modules and broke thousands of dependent projects? npm's Ashley Williams "admitted that the left-pad debacle happened because of naive policies at npm. Since, the npm team have devised new policies, the main one being that you are only allowed to unpublish a package within 24 hours of publishing it." And their new dissociate and deprecate policy allows developers to mark packages as "unmaintained" without erasing them from the registry.
