Thirty years ago today, Netscape Communications and Sun Microsystems issued a joint press release announcing JavaScript, an object scripting language designed for creating interactive web applications. The language emerged from a frantic 10-day sprint at pioneering browser company Netscape, where engineer Brendan Eich hacked together a working internal prototype during May 1995.

While the JavaScript language didn’t ship publicly until that September and didn’t reach a 1.0 release until March 1996, the descendants of Eich’s initial 10-day hack now run on approximately 98.9 percent of all websites with client-side code, making JavaScript the dominant programming language of the web. It’s wildly popular; beyond the browser, JavaScript powers server backends, mobile apps, desktop software, and even some embedded systems. According to several surveys, JavaScript consistently ranks among the most widely used programming languages in the world. //

The JavaScript partnership secured endorsements from 28 major tech companies, but amusingly, the December 1995 announcement now reads like a tech industry epitaph. The endorsing companies included Digital Equipment Corporation (absorbed by Compaq, then HP), Silicon Graphics (bankrupt), and Netscape itself (bought by AOL, dismantled). Sun Microsystems, co-creator of JavaScript and owner of Java, was acquired by Oracle in 2010. JavaScript outlived them all. //

Confusion about its relationship to Java continues: The two languages share a name, some syntax conventions, and virtually nothing else. Java was developed by James Gosling at Sun Microsystems using static typing and class-based objects. JavaScript uses dynamic typing and prototype-based inheritance. The distinction between the two languages, as one Stack Overflow user put it in 2010, is similar to the relationship between the words “car” and “carpet.” //

The language now powers not just websites but mobile applications through frameworks like React Native, desktop software through Electron, and server infrastructure through Node.js. Somewhere around 2 million to 3 million packages exist on npm, the JavaScript package registry.

Ping & traceroute
If you suspect a network problem between the monitoring system and your server, it’s helpful to have a traceroute from your NTP server to the monitoring system. You can traceroute to the monitoring network using 139.178.64.42 and 2604:1380:2:6000::15.

You can ping or traceroute from the monitoring network using HTTP, with:

curl http://trace.ntppool.org/traceroute/8.8.8.8
curl http://trace.ntppool.org/ping/8.8.8.8

for /l %i in (1,1,254) do @ping 192.168.1.%i -w 10 -n 1 | find "Reply"

This will ping all addresses from 192.168.1.1 to 192.168.1.254 one time each, wait 10ms for a reply (more than enough time on a local network) and show only the addresses that replied.

All of your MX record, DNS, blacklist and SMTP diagnostics in one integrated tool.  Input a domain name or IP Address or Host Name. Links in the results will guide you to other relevant tools and information.  And you'll have a chronological history of your results. 

If you already know exactly what you want, you can force a particular test or lookup.  Try some of these examples:

It’s always DNS
Amazon said the root cause of the outage was a software bug in software running the DynamoDB DNS management system. The system monitors the stability of load balancers by, among other things, periodically creating new DNS configurations for endpoints within the AWS network. A race condition is an error that makes a process dependent on the timing or sequence events that are variable and outside the developers’ control. The result can be unexpected behavior and potentially harmful failures.

In this case, the race condition resided in the DNS Enactor, a DynamoDB component that constantly updates domain lookup tables in individual AWS endpoints to optimize load balancing as conditions change. As the enactor operated, it “experienced unusually high delays needing to retry its update on several of the DNS endpoints.” While the enactor was playing catch-up, a second DynamoDB component, the DNS Planner, continued to generate new plans. Then, a separate DNS Enactor began to implement them.

The timing of these two enactors triggered the race condition, which ended up taking out the entire DynamoDB.

The NTP Pool DNS Mapper tries mapping user IP addresses to their DNS servers (and vice-versa). It also tracks which servers support EDNS-SUBNET and how well that actually matches the client IP (as seen by the HTTP server). You can see a demo at mist.ntppool.org.

It's done to research how to improve the DNS system used by the NTP Pool and potentially other similar applications.

How can I help?
Thank you for asking! The easiest way to help is to help get more data.

If you have a website you can have your users help by adding one of the following two code snippets to your site.

It would be somewhat understandable that Autopilot stops working because Eight Sleep’s backend is down but not being able to even adjust the temperature locally is ridiculous and completely unacceptable for such a high-end (and expensive) product.

A person on X wrote: “Would be great if my bed wasn’t stuck in an inclined position due to an AWS outage. Cmon now.” //

Eight Sleep users will be relieved to hear that the company is working to make their products usable during Internet outages. But many are also questioning why Eight Sleep didn’t implement local control sooner. This isn’t Eight Sleep’s first outage, and users can also experience personal Wi-Fi problems. And there’s an obvious user benefit to being able to control their bed’s elevation and temperature without the Internet or if Eight Sleep ever goes out of business.

For Eight Sleep, though, making flagship features available without its app while still making enough money isn’t easy. Without forcing people to put their Eight Sleep devices online, it would be harder for Eight Sleep to convince people that Autopilot subscriptions should be mandatory. //

“AWS ate my sleep” wasn’t on my Bingo card.

One company, a California-based startup named Muon Space, is partnering with SpaceX to bring Starlink connectivity to low-Earth orbit. Muon announced Tuesday it will soon install Starlink terminals on its satellites, becoming the first commercial user, other than SpaceX itself, to use Starlink for in-flight connectivity in low-Earth orbit. //

Putting a single Starlink mini-laser terminal on a satellite would keep the spacecraft connected 70 to 80 percent of the time, according to Greg Smirin, Muon’s president. There would still be some downtime as the laser reconnects to different Starlink satellites, but Smirin said a pair of laser terminals would allow a satellite to reach 100 percent coverage. //

SpaceX’s mini-lasers are designed to achieve link speeds of 25Gbps at distances up to 2,500 miles (4,000 kilometers). These speeds will “open new business models” for satellite operators who can now rely on the same “Internet speed and responsiveness as cloud providers and telecom networks on the ground,” Muon said in a statement. //

Live video from space has historically been limited to human spaceflight missions or rocket-mounted cameras that operate for a short time.

One example of that is the dazzling live video beamed back to Earth, through Starlink, from SpaceX’s Starship rockets. The laser terminals on Starship operate through the extreme heat of reentry, returning streaming video as plasma envelops the vehicle. This environment routinely causes radio blackouts for other spacecraft as they reenter the atmosphere. With optical links, that’s no longer a problem.

“This starts to enable a whole new category of capabilities, much the same way as when terrestrial computers went from dial-up to broadband,” Smirin said. “You knew what it could do, but we blew through bulletin boards very quickly to many different applications.”

Announced on September 24, Cloudflare’s Content Signals Policy is an effort to use the company’s influential market position to change how content is used by web crawlers. It involves updating millions of websites’ robots.txt files. //

Historically, robots.txt simply includes a list of paths on the domain that were flagged as either “allow” or “disallow.” It was technically not enforceable, but it became an effective honor system because there are advantages to it for the owners of both the website and the crawler: Website owners could dictate access for various business reasons, and it helped crawlers avoid working through data that wouldn’t be relevant. //

The Content Signals Policy initiative is a newly proposed format for robots.txt that intends to do that. It allows website operators to opt in or out of consenting to the following use cases, as worded in the policy:

• search: Building a search index and providing search results (e.g., returning hyperlinks and short excerpts from your website’s contents). Search does not include providing AI-generated search summaries.
• ai-input: Inputting content into one or more AI models (e.g., retrieval augmented generation, grounding, or other real-time taking of content for generative AI search answers).
• ai-train: Training or fine-tuning AI models.

Cloudflare has given all of its customers quick paths for setting those values on a case-by-case basis. Further, it has automatically updated robots.txt on the 3.8 million domains that already use Cloudflare’s managed robots.txt feature, with search defaulting to yes, ai-train to no, and ai-input blank, indicating a neutral position.

Scientists at the University of California, San Diego, and the University of Maryland, College Park, say they were able to pick up large amounts of sensitive traffic largely by just pointing a commercial off-the-shelf satellite dish at the sky from the roof of a university building in San Diego.

In its paper, Don't Look Up: There Are Sensitive Internal Links in the Clear on GEO Satellites [PDF], the team describes how it performed a broad scan of IP traffic on 39 GEO satellites across 25 distinct longitudes and found that half of the signals they picked up contained cleartext IP traffic.

This included unencrypted cellular backhaul data sent from the core networks of several US operators, destined for cell towers in remote areas. Also found was unprotected internet traffic heading for in-flight Wi-Fi users aboard airliners, and unencrypted call audio from multiple VoIP providers.

According to the researchers, they were able to identify some observed satellite data as corresponding to T-Mobile cellular backhaul traffic. This included text and voice call contents, user internet traffic, and cellular network signaling protocols, all "in the clear," but T-Mobile quickly enabled encryption after learning about the problem.

More seriously, the team was able to observe unencrypted traffic for military systems including detailed tracking data for coastal vessel surveillance and operational data of a police force.

In addition, they found retail, financial, and banking companies all using unencrypted satellite communications to link their internal networks at various sites. The researchers were able to see unencrypted login credentials, corporate emails, inventory records, and information from ATM cash dispensers.

Are your links not malicious looking enough?
This tool is guaranteed to help with that!

What is this and what does it do?
This is a tool that takes any link and makes it look malicious. It works on the idea of a redirect. Much like https://tinyurl.com/ for example. Where tinyurl makes an url shorter, this site makes it look malicious.

Place any link in the below input, press the button and get back a fishy(phishy, heh...get, it?) looking link. The fishy link doesn't actually do anything, it will just redirect you to the original link you provided.

It’s official: AOL’s dial-up internet has taken its last bow.

AOL previously confirmed it would be pulling the plug on Tuesday (Sept. 30) — writing in a brief update on its support site last month that it “routinely evaluates” its offerings and had decided to discontinue dial-up, as well as associated software “optimized for older operating systems,” from its plans.

Dial-up is now no longer advertised on AOL’s website. As of Wednesday, former company help pages like “connect to the internet with AOL Dialer” appeared unavailable — and nostalgic social media users took to the internet to say their final goodbyes.

If you're going to use test values in your test systems, why not use test values allocated for documentation purposes that aren't expected to be used in "live" networks?

IETF RFC 5737 section 3 allocates three IPv4 CIDR ranges for documentation:
192.0.2.0/24, 198.51.100.0/24, and 203.0.113.0/24.

Re: I saw similar a couple times in that timeframe ...
My recollection, because I started to make phone bill payments in those years, was that the local operating telcos (first the “Baby Bells” and then their ever-merging successors) had two types of residential service on offer: one at a nominally lower base cost plus a charge for every local call, and one at a supposedly higher base cost that allowed unlimited local calling. Both, of course, charged a king’s ransom for a domestic long-distance call. An overseas long-distance call required a cardiologist when your bill arrived.

The Web Era arrives, the browser wars flare, and a bubble bursts.

Welcome to the second article in our three-part series on the history of the Internet. //

In 1965, Ted Nelson submitted a paper to the Association for Computing Machinery. He wrote: “Let me introduce the word ‘hypertext’ to mean a body of written or pictorial material interconnected in such a complex way that it could not conveniently be presented or represented on paper.” The paper was part of a grand vision he called Xanadu, after the poem by Samuel Coleridge.

A decade later, in his book “Dream Machines/Computer Lib,” he described Xanadu thusly: “To give you a screen in your home from which you can see into the world’s hypertext libraries.” He admitted that the world didn’t have any hypertext libraries yet, but that wasn’t the point. One day, maybe soon, it would. And he was going to dedicate his life to making it happen.

"The NYT portrayed the Marubo people as a community unable to handle basic exposure to the internet, highlighting allegations that their youth had become consumed by pornography shortly after receiving access," the plaintiffs say.
