Dwindling investment in oil, gas and coal means high prices are here to stay //
FOR MUCH of the past half-decade, the operative word in the energy sector was “abundance”. An industry that had long sought to ration the production of fossil fuels to keep prices high suddenly found itself swamped with oversupply, as America’s shale boom lowered the price of oil around the world and clean-energy sources, such as wind and solar, competed with other fuels used for power generation, such as coal and natural gas.
In recent weeks, however, it is a shortage of energy, rather than an abundance of it, that has caught the world’s attention. On the surface, its manifestations are mostly unconnected.

ANY LIST OF THE MOST FAMOUS FINNS in the world today would be incomplete without the inclusion of Linus Torvalds, the software developer who created Linux, the world’s largest open-source operating system. //
Although Torvalds resides in the heart of Silicon Valley today and has a net worth of around $150 million, his origins are somewhat humbler, although by no means working class. He was born on 28 December 1969 to Finnish Swedish parents, one of whom is the journalist and MP Nils Torvalds. His grandfathers were Leo Törnqvist, another famous Finland Swede who was Finland’s first-ever statistician, and Ole Torvalds, the celebrated poet, and journalist. It was Törnqvist, his maternal grandfather, who first sparked Torvalds’ interest in computing, after asking him to help program his brand-new Commodore VIC-20 computer in 1981. //
In 1997, Torvalds left Helsinki and decamped in California, where he continues to work with the Open-Source Development Lab, a consortium of big tech players such as Intel, Siemens, and IBM that advocate for Linux development. His wife of almost 30 years is the six-time Finnish national karate champion Tove Torvalds, and both have been US citizens since 2010. However, Torvalds still returns to his homeland to give talks, especially at his old alma mater, the University of Helsinki.

Mr. Woolman, founder of Delta Air Lines, said it best, “Consideration is an extension of safety. It begins with the first contact with our passengers, no matter where this is—reservations, porter, ticket agent or wherever. Make the customer feel special. There’s more to flying than just buying a ticket.” Do we sometimes fail, of course. But we try to learn from our mistakes and correct them. Delta’s management stresses that our success is based on Mr. Woolman’s philosophy of hiring the best people to do the job, paying them a good wage, appreciating their work and treating us with respect. In my years with Delta, I’ve had some issues…every family has issues. But, in the end, the fair treatment of our passengers is a direct result of management’s philosophy of… “stay within the box” but if you must go outside of the box, do what is right and we’ll back you up. The key is “back you up” SouthWest and Alaska both run great airlines because they empower their people to do well. They don’t belittle their employees. Ask any AA employee if they remember when “Dougie” got a DUI or when he told them that they have nothing to do with the company’s profitability. Jerry Grinstein said it best when he told Delta employees that we have everything to do with profitability.

WINNING: Fox Business' @CGasparino is reporting that major Wall Street firms are ditching critical race theory training programs, partially in response to my reporting that embarrassed American Express and other companies.
Public exposure works.
Big Biz has found that Critical Race Theory is bad for business
nypost.com //
And sure, it’d be easy to read these newer shifts away from CRT off as too marginal of a victory. Those companies will still have “diversity training” of some sort. Yet, how long has it been since the right has gained any real ground culturally, especially in the arena of how we view race as an aspect of society? Any battles won against CRT are noteworthy, even if the war continues.
The zpool configuration at rsync.net is simple and straightforward: we create 12 disk raidz-3 vdevs (which can sustain 3 disk failures without data loss) and concatenate them into zpools.
This allows for a nice, even, five vdevs per 60 drive JBOD. 12x16TB disks in one vdev is still a number we (and our retained consultants at Klara Systems[1]) are comfortable with.
We also employ three SSD cache drives per zpool - one single drive for L2ARC and a mirrored pair of drives for the SLOG. This is a very standard configuration and anyone working professionally with ZFS will recognize it. //
We maintain a full complement of checksum commands that you can run, over ssh, to verify files:
ssh user@rsync.net rmd160 some/fileThe full list of checksum commands is:
md5 sha1 sha224 sha256 sha384 sha512 sha512t256 rmd160 skein256 skein512 skein1024 cksum... and note the last one in the list, 'cksum' ...
cksum is interesting because if your use-case is not security or collision detection but, rather, simple verification of file transfer and/or integrity, cksum is much, much faster than the "serious" checksum tools. You should consider cksum if you have simple integrity checks to do on millions of files, etc.
The purpose of this page is to answer commonly asked questions about Pine and give advanced information related to these answers. The main point of this page is that much of the help that exists today about Pine is not completely satisfactory in my opinion, in the sense that it lacks a more general view. In order to explain this, much of the help is written on the form of "how do I do this?", or as an explanation of a feature that already exists in Pine.
This page takes a different approach to helping you improve your experience with Pine. Instead of answering questions or explaining features, this page gives an in-depth description behind each screen and configuration option. I describe each screen, what configuration options relate to it, what are the advantages and disadvantages of setting them. I do also answer questions like "How do I?", but my main intention is to give you a full picture of what you can (and can't) do.
A security auditor for our servers has demanded the following within two weeks:
- A list of current usernames and plain-text passwords for all user accounts on all servers
- A list of all password changes for the past six months, again in plain-text
- A list of "every file added to the server from remote devices" in the past six months
- The public and private keys of any SSH keys
- An email sent to him every time a user changes their password, containing the plain text password
We're running Red Hat Linux 5/6 and CentOS 5 boxes with LDAP authentication.
As far as I'm aware, everything on that list is either impossible or incredibly difficult to get, but if I don't provide this information we face losing access to our payments platform and losing income during a transition period as we move to a new service. Any suggestions for how I can solve or fake this information? //
ask him directly how to execute his requirements -- admit you don't know how, and would like to leverage his experience. Once you're out and gone, a response to his "I have over 10 years experience in security auditing" would be "no, you have 5 minutes of experience repeated hundreds of times".

The rsync.net platform is so simple that our first PCI scan vendor, in 2006, could not actually verify that we were up and running.
We offered so little attack surface for their scans that they (incorrectly) assumed we were offline.
Our platform only answers on port 22 with OpenSSH.
That's it.
I do security and I title this "Most secured platform in the world."

The three golden rules of computer security: do not own a computer, do not power it on, and do not use it.
The purpose of this page is to distribute releases of Alpine, as well as to provide users with documentation on Alpine. All documentation needed to configure Alpine can be found in the binary, and this page may provide extra documentation. In any case, you are not required, nor encouraged to access this site to run Alpine. You can run Alpine in your computer without the need to ever visit this site. All documentation needed to configure Alpine can be found in the binary, and can be read by either pressing the "?" command or by pressing "^G" in Alpine.
rsync.net is not built on a cloud platform - we own (and have built) all of our own platform. Our storage arrays, as we call them, are 2U “head units” with x16 2.5" drive slots and one or more SAS HBAs.
ZFS makes good use of fast cache storage so, after using up two drive slots for our boot mirror (which is always a mix of two totally different SSDs) we have room for up to 14 more SSDs for read (L2ARC) and write (SLOG) cache. ZFS is also RAM hungry so we choose a motherboard that can support up to 2TB of RAM.
Attached to these head units, externally, are one or more JBOD chassis filled with hard drives. JBOD stands for “just a bunch of disks” and they are typically 4U chassis containing 45 or 60 drives that attach back to the head unit with SAS cables.
rsync.net has no firewalls and no routers. In each location we connect to our IP provider with a dumb, unmanaged switch.
This might seem odd, but consider: if an rsync.net storage array is a FreeBSD system running only OpenSSH, what would the firewall be ? It would be another FreeBSD system with only port 22 open. That would introduce more failure modes, fragility and complexity without gaining any security.
- Restic is multi-threaded, borg is not. This translates to restic being extremely fast in comparison to borg, but borg having less impact on average on CPU usage while running. This limitation in borg is actually a direct consequence of the next point.
- Borg does actual deduplication, while restic only does classic incremental backups. With restic, you store a copy of every file, but the files are reference counted so that each version of a file only gets stored once. Borg, however, operates on blocks, not files, and deduplicates within individual backups. So if you have a dozen copies of the same data in your backup, restic stores each copy, but borg only stores the first and makes all the others references to that. The main benefit of this is that borg produces much smaller backups when you have lots of duplicate data and actually does more space efficient incremental backups (because it only stores what actually changed, not the whole changed file).
- Borg supports compression, while Restic seemingly does not (and doesn't handle sparse files very well either). This too has a huge impact on space efficiency, and may explain why restic is lightning fast on my systems when compared to borg. //
Austin I have to correct you:
Restic does indeed do deduplication on blocklevel. It uses a rolling hash algorithm called rabin as a chunker.
In short, a rolling hash algorithm reacts to patterns within the file and cuts it. If two files have the same patterns there's a high chance to have the cuts at the same positions, giving it the ability to deduplicate files which's data is not aligned to any specific block size.

“Our eight Lufthansa B747-400 aircraft will get reactivated and taken out of storage step by step and put back in operation for the upcoming years. This is only until they will get replaced by the Boeing 777-9, also step by step. There are no fixed timelines on this exchange, however.”
“I’m very proud of the fact that there’s actually a fair number of people still involved with the kernel that came in in 1991 — I mean, literally 30 years ago.” (Hohndel is one of them.)
The longevity of the Linux community is especially impressive in light of how few contributors there were back in 1991, Torvalds said: “I think that’s a testament to how good the community, on the whole, has been, and how much fun it’s been.”
Yes, fun — and Torvalds still considers that one of the building blocks of the Linux community; “just for fun,” he said, is part of what he still strives for.
It comes up when people talk about the possibility of writing some Linux kernel modules using Rust. “From a technical angle, does that make sense?” Torvalds asked. “Who knows. That’s not the point. The point is for a project to stay interesting — and to stay fun — you have to play with it.” //
The keynote conversation closed with Hohndel asking what they should do for the 50th anniversary of Linux, in the year 2041, when both of them will be in their 70s.
Characteristically Torvalds answered that, just like with the Linux kernel, he doesn’t make plans more than six months out. But the question did draw some reflection. “I’ve been very happy doing the kernel for 30 years,” Torvalds began thoughtfully.
“Somehow I don’t see myself doing kernel programming when I’m 70. But on the other hand, I didn’t see myself doing kernel programming when I was 50 either, a few years back. So… we’ll see.”
This band of strong wind separates cold air from the Arctic from warmer air to the south, and it's responsible for transporting weather from west to east across the US, over the Atlantic, and into Europe. It controls how wet and warm these regions are.
But according to a recent study, the jet stream is shifting north as global temperatures rise. That's because the delicate balance of warm and cold air that keeps the stream in place is getting disturbed. If greenhouse-gas emissions continue unabated, the study found, the jet stream will break out of its normal range by 2060.
"The 'onset' of the jet stream's northward migration may have already begun," Matthew Osman, a researcher at the University of Arizona's Climate Systems Center who co-authored the study, told Insider.
