Sometimes obvious things are obvious only looking back

 

Highlights

European beech trees more than 1,500 kilometers apart all drop their fruit at the same time in a grand synchronization event now linked to the summer solstice.

From England to Sweden to Italy — across multiple seas, time zones and climates — somehow these trees “know” when to reproduce. But how?

Their analysis of over 60 years’ worth of seeding data suggests that European beech trees time their masting to the summer solstice and peak daylight.

The discovery of the genetic mechanism that governs this solstice-monitoring behavior could bring researchers closer to understanding many other mysteries of tree physiology.

So it’s easy to see why masting trees synchronize their seed production. Understanding how they do it, however, is more complicated. Plants usually synchronize their reproduction by timing it to the same weather signals.

Then the team stumbled across a clue by accident. One summer evening, Bogdziewicz was sitting on his balcony reading a study which found that the timing of leaf senescence — the natural aging process leaves go through each autumn — depends on when the local weather warms relative to the summer solstice. Inspired by this finding, he sent the paper to his research group and called a brainstorming session.

It’s the first time that researchers have identified day length as a cue for masting. While Koenig cautioned that the result is only correlational, he added that “there’s very little out there speculating on how the trees are doing what they’re doing.”

If the solstice is shown to activate a genetic mechanism, it would be a major breakthrough for the field. Currently, there’s little data to explain how trees behave as they do. No one even knows whether trees naturally grow old and die, Vacchiano said. Ecologists struggle just to study trees: From branches to root systems, the parts of a tree say very little about the physiology of the tree as a whole. What experts do know is that discovering how trees sense their environment will help them answer the questions that have been stumping them for decades.

Got some time to read the article: I am sure, that India is not an exception in leaking and being in deep shit in regards to storing sensitive data.

Seems that we should assume that we cannot prevent data leaks. So the question is - how can we deal with the aftermath?

A Leak of Biometric Police Data Is a Sign of Things to Come

Highlights

Thousands of law enforcement officials and people applying to be police officers in India have had their personal information leaked online—including fingerprints, facial scan images, signatures, and details of tattoos and scars on their bodies.

While the misconfigured server has now been closed off, the incident highlights the risks of companies collecting and storing biometric data, such as fingerprints and facial images, and how they could be misused if the data is accidentally leaked.

“A lot of data is collected in India, but nobody's really bothered about how to store it properly,” Narayan says. Data breaches are happening so regularly that people have “lost that surprise shock factor,”

So many other countries are looking at biometric verification for identities, and all of that information has to be stored somewhere,” Fowler says. “If you farm it out to a third-party company, or a private company, you lose control of that data. When a data breach happens, you’re in deep shit, for lack of a better term.

When Regulation Encourages ISPs to Hack Their Customers

Highlights

KT, formerly Korea Telecom, has been accused of deliberately infecting 600,000 of its own customers with malware to reduce peer-to-peer file sharing traffic. This is a bizarre hack and a great case study of how government regulation has distorted the South Korean internet.

South Korean media outlet JTBC reported last month that KT had infected customers who were using Korean cloud data storage services known as 'webhards' (web hard drives). The malware disabled the webhard software, resulted in files disappearing and sometimes caused computers to crash.

JTBC news says the team involved "consisted of a 'malware development' section, a 'distribution and operation' section, and a 'wiretapping' section that looked at data sent and received by KT users in real time".

The company‬ ‭claims that the people involved in the webhard hack were a small group operating independently. It's just an amazing coincidence that they just happened to invest so much time and effort into a caper that aligned so well with KT's financial interests!‬‭

South Korea has a 'sender pays' model in which ISPs must pay for traffic they send to other ISPs, breaking the worldwide norm of 'settlement-free peering', voluntary arrangements whereby ISPs exchange traffic without cost.

Once the sender pays rules were enforced, however, KT was left with large bills from its peer ISPs for the Facebook traffic sent from the cache in its network. KT tried to recoup costs from Facebook, but negotiations broke down and Facebook disabled the cache. South Korean users were instead routed over relatively expensive links to overseas caches with increased latency.

These sender pays rules may also encourage peer-to-peer file sharing relative to more centralised pirate content operations.

An unnamed sales manager from a webhard company told TorrentFreak torrent transfers saved them significant bandwidth costs, but as long as traffic flows between ISPs, someone will pay. KT is South Korea's largest broadband provider, so since it has more customers, peer-to-peer file sharing means that the company has to pay fees to its competitor ISPs.

Either way, this is just a great example of where unusual regulation can produce unusual results.

Pluralistic: The reason you can't buy a car is the same reason that your health insurer let hackers dox you (28 Jun 2024)

Metadata

Highlights

Equifax knew the breach was coming. It wasn't just that their top execs liquidated their stock in Equifax before the announcement of the breach – it was also that they ignored years of increasingly urgent warnings from IT staff about the problems with their server security.

Just like with Equifax, the 737 Max disasters tipped Boeing into a string of increasingly grim catastrophes.

Equifax isn't just a company: it's infrastructure.

This witch-hunts-as-a-service morphed into an official part of the economy, the backbone of the credit industry, with a license to secretly destroy your life with haphazardly assembled "facts" about your life that you had the most minimal, grudging right to appeal (or even see).

There's a direct line from that acquisition spree to the Equifax breach(es). First of all, companies like Equifax were early adopters of technology. They're a database company, so they were the crash-test dummies for ever generation of database.

There's a reason libraries, cities, insurance companies, and other giant institutions keep getting breached: they started accumulating tech debt before anyone else, so they've got more asbestos in the walls, more sagging joists, more foundation cracks and more termites.

The reason to merge with your competitors is to create a monopoly position, and the value of a monopoly position is that it makes a company too big to fail, which makes it too big to jail, which makes it too big to care.

The biggest difference was that Boeing once had a useful, high-quality product, whereas Equifax started off as an irredeemably terrible, if efficient, discrimination machine, and grew to become an equally terrible, but also ferociously incompetent, enterprise.

Every corporate behemoth is locked in a race between the eventual discovery of its irreparable structural defects and its ability to become so enmeshed in our lives that we have to assume the costs of fixing those defects. It's a contest between "too rotten to stand" and "too big to care."

Remember how we discovered this? Change was hacked, went down, ransomed, and no one could fill a scrip in America for more than a week, until they paid the hackers $22m in Bitcoin?

Well, first Unitedhealthcare became the largest health insurer in America by buying all its competitors in a series of mergers that comatose antitrust regulators failed to block. Then it combined all those other companies' IT systems into a cosmic-scale dog's breakfast that barely ran. Then it bought Change and used its monopoly power to ensure that every Rx ran through Change's servers, which were part of that asbestos-filled, termite-infested, crack-foundationed, sag-joisted teardown. Then, it got hacked.

Good luck with that. There's a company you've never heard. It's called CDK Global. They provide "dealer management software." They are a monopolist. They got that way after being bought by a private equity fund called Brookfield. You can't complete a car purchase without their systems, and their systems have been hacked.

What happens next is a near-certainty: CDK will pay a multimillion dollar ransom, and the hackers will reward them by breaching the personal details of everyone who's ever bought a car, and the slaves in Cambodian pig-butchering compounds will get a fresh supply of kompromat.

But on the plus side, the need to pay these huge ransoms is key to ensuring liquidity in the cryptocurrency markets, because ransoms are now the only nondiscretionary liability that can only be settled in crypto

How We Built the Internet

Metadata

Highlights

The internet is a universe of its own.

The infrastructure that makes this scale possible is similarly astounding—a massive, global web of physical hardware, consisting of more than 5 billion kilometers of fiber-optic cable, more than 574 active and planned submarine cables that span a over 1 million kilometers in length, and a constellation of more than 5,400 satellites offering connectivity from low earth orbit (LEO).

“The Internet is no longer tracking the population of humans and the level of human use. The growth of the Internet is no longer bounded by human population growth, nor the number of hours in the day when humans are awake,” writes Geoff Huston, chief scientist at the nonprofit Asia Pacific Network Information Center.

As Shannon studied the structures of messages and language systems, he realized that there was a mathematical structure that underlied information. This meant that information could, in fact, be quantified.

Shannon noted that all information traveling from a sender to a recipient must pass through a channel, whether that channel be a wire or the atmosphere.

Shannon’s transformative insight was that every channel has a threshold—a maximum amount of information that can be delivered reliably to a sender.

Kleinrock approached AT&T and asked if the company would be interested in implementing such a system. AT&T rejected his proposal—most demand was still in analog communications. Instead, they told him to use the regular phone lines to send his digital communications—but that made no economic sense.

What was exceedingly clever about this suite of protocols was its generality. TCP and IP did not care which carrier technology transmitted its packets, whether it be copper wire, fiber-optic cable, or radio. And they imposed no constraints on what the bits could be formatted into—video text, simple messages, or even web pages formatted in a browser.

David Clark, one of the architects of the original internet, wrote in 1978 that “we should … prepare for the day when there are more than 256 networks in the Internet.”

Fiber was initially laid down by telecom companies offering high-quality cable television service to homes. The same lines would be used to provide internet access to these households. However, these service speeds were so fast that a whole new category of behavior became possible online. Information moved fast enough to make applications like video calling or video streaming a reality.

And while it may have been the government and small research groups that kickstarted the birth of the internet, its evolution henceforth was dictated by market forces, including service providers that offered cheaper-than-ever communication channels and users that primarily wanted to use those channels for entertainment.

In 2022, video streaming comprised nearly 58 percent of all Internet traffic. Netflix and YouTube alone accounted for 15 and 11 percent, respectively.

At the time, Facebook users in Asia or Africa had a completely different experience to their counterparts in the U.S. Their connection to a Facebook server had to travel halfway around the world, while users in the U.S. or Canada could enjoy nearly instantaneous service. To combat this, larger companies like Google, Facebook, Netflix, and others began storing their content physically closer to users through CDNs, or “content delivery networks.”

Instead of simply owning the CDNs that host your data, why not own the literal fiber cable that connects servers from the United States to the rest of the world?

Most of the world’s submarine cable capacity is now either partially or entirely owned by a FAANG company—meaning Facebook (Meta), Amazon, Apple, Netflix, or Google (Alphabet).

Google, which owns a number of sub-sea cables across the Atlantic and Pacific, can deliver hundreds of terabits per second through its infrastructure.

In other words, these applications have become so popular that they have had to leave traditional internet infrastructure and operate their services within their own private networks. These networks not only handle the physical layer, but also create new transfer protocols —totally disconnected from IP or TCP. Data is transferred on their own private protocols, essentially creating digital fiefdoms.

SpaceX’s Starlink is already unlocking a completely new way of providing service to millions. Its data packets, which travel to users via radio waves from low earth orbit, may soon be one of the fastest and most economical ways of delivering internet access to a majority of users on Earth. After all, the distance from LEO to the surface of the Earth is just a fraction of the length of subsea cables across the Atlantic and Pacific oceans.

i don't see secure messaging in your profile neither :)

[–] [email protected] 2 points 1 year ago (5 children)

at least this is the format i am using.

[–] [email protected] 8 points 1 year ago (14 children)

not all the users put their matrix username in Lemmy. also - at least in desktop when clicking send secure message it brings up matrix client for me (element)

[–] [email protected] 6 points 1 year ago* (last edited 1 year ago) (16 children)

in lemmy at least in the user profile you can see send secure message - if it is there (meaning - user has added matrix username) - you can click and send message via matrix

usually i add more than 1 ip and also vultr firewall can be managed to change ip. tailscale can be used as well. there are options!

[–] [email protected] 1 points 1 year ago (5 children)

if you configure ssh access only from your home ip - then fail2ban is not needed.

[–] [email protected] 1 points 1 year ago (7 children)

sorry, this is kinda like a firewall, but protecting websites, so many vulnerabilities are filtered out. it does not protect you 100% percent (nothing does). it might be hard to setup, in that case there is an option to use waf as a service, i.e. - cloudflare has such offering, maybe there are others as well. i have looked into vultr - they seem to offer only a "usual" type of firewall, not http/application based.

Get some WAF for the public facing app, maybe at least https://github.com/nbs-system/naxsi .

[–] [email protected] 1 points 1 year ago

yes, indeed ;)

[–] [email protected] 39 points 1 year ago

That's my kind of people!
