IRTT uses UDP packets to measure round-trip time, one-way delay and other metrics. Sends packets for a fixed period and then produces both user and machine parseable output. I likes it for monitoring connection performance: “I use [this] to simulate a voice call (where jitter matters the most) to a server where I can control the network. I use a custom tool to parse the output and insert it into influxdb for graphing/alerting.”
Sshwifty provides an SSH and Telnet access interface that allows you to connect computers and servers via a standard web browser.

A clarification on the confusingly worded relationship between an ‘ethernet cable’ and ‘ethernet’:
“A protocol is independent of the medium that transports it. What we call Ethernet cables are really shielded or unshielded twisted pair CAT 5/5e/6/etc cables, terminated with RJ45 plugs in TIA 568 A/B wiring. That’s complicated to say, so we just refer to the cable by its purpose, which is typically to carry Ethernet frames.
Other cables can carry Ethernet. This is seen in a lot of HDMI cables for smart TVs.
Ethernet cables don’t have to carry Ethernet. In my line of work (corporate audio/visual) they can be used to carry control signals such as RS-232, or broken down into their twisted pairs to carry audio signal from microphones.”

Google’s business-friendly phone list has a big problem
Google has a whole program designed to help you know which Android devices are guaranteed to be as up-to-date and secure as possible. But when you actually start digging into its recommendations, you find some pretty alarming patterns.
Lots of the phones on Google’s Android Enterprise Recommended list — a list of devices that come with the promise of “timely security patches and clear information about major updates,” among other things — simply aren’t keeping up with the program’s most basic vows. And yet, they’re still being featured prominently as part of the official Google collection. Even worse, this pattern’s been going on for years now. My hope is that drawing attention to this issue will not only make everyone aware of the realities surrounding these mostly meaningless recommendations but also lead to some manner of change. Knowledge truly is power in a situation like this — and, if we’re lucky, it might also be the first step toward accountability.
Google I/O is now just days away
Google kicks off its annual I/O extravaganza this coming Wednesday, and we’re expecting to see plenty o’ juicy new revelations about our favorite platforms, apps, and devices.
It’s all but certain Le Googlé will give us a clearer picture of Android 13’s still-hidden headline features at its upcoming event — but beyond that, rumors suggest we could get our first glimpse at the potentially pivotal Pixel 6a midrange phone along with the long-fabled Pixel Watch. Plus, big-ticket items aside, I/O almost always includes a bunch of small but significant updates to services like Photos and Assistant. And honestly, those less emphasized announcements often end up being the ones with the most meaningful, lasting impact on our day-to-day lives.
You can find the full I/O schedule as well as live streams of all the action on the official Google I/O website.
Android’s navigation system could be getting a(nother) makeover
An unassuming item on the I/O agenda suggests Android’s system-wide back navigation command is about to get a hefty injection of extra intelligence.
The specifics on what exactly this means are still slim, but the session describes how “the future of Android” will introduce “predictive back navigation” into the software. Given the fact that Android’s current swipe-in-from-the-side back gesture often overlaps with other swipe-oriented actions, it certainly seems like some manner of A.I.-related smarts could be coming into the equation and helping your phone figure out what you’re trying to do based on the current context. That could bring a big and very Googley enhancement to the core act of getting around Android — something we’d all appreciate, even if we don’t explicitly realize why.
This in-depth analysis has a thoughtful overview of what we know so far and how it could all come together.
Google’s in the midst of rolling out a really cool new feature to its Chrome Android browser: an optional new button that sits in the browser’s address bar area and gives you one-tap access to the app’s share command, new tab command, or voice search system.
What’s especially cool is that you can pick which of those options seems most useful to you — or you can let Chrome automatically decide which option you’re most likely to need at any given moment and contextually change the button for you.
Google is slowly rolling this new feature out as we speak, which means you might not have access to it on your phone for a matter of days or maybe even weeks. But with about 10 seconds of simple tweaking, you can enable it on any Android device this minute.
Here’s the secret:
- Open up Chrome on your phone.
- Type chrome:flags into the address bar.
- Type adaptive into the search box on the screen that comes up.
- See the line labeled “Adaptive button in top toolbar customization”? Tap the box beneath it and change it from “Default” to “Enabled.”
- Tap the blue Relaunch button at the bottom of the screen.
And that’s it! Once the browser reloads, just tap the three-dot menu in its upper-right corner and select “Settings” followed by “Toolbar shortcut.” You’ll be able to turn your fancy new feature on right then and there and select exactly how you want it to work.
Grant yourself a time-saving tab superpower in Chrome on your computer
Another interesting new time-saver is on its way to Chrome right now — this time, on the desktop side.
Google’s cookin’ up a cool new shortcut system for the Chrome computer browser that’ll let you rearrange tabs within a window without ever having to lift your precious fingies off your keyboard. And if you (a) tend to keep as many tabs open as I do and (b) are as obsessed with keyboard shortcuts as I am, you’re definitely gonna love this.
The way it works is simple: You just hold down Ctrl and Shift on your keyboard and then hit Page Up to shift a tab over to the left within its current window or Page Down to move it over to the right.
There’s no telling when this feature will make its way out of development and into your grubby little paws, but you can give yourself identical powers this second by installing the creatively named Keyboard Shortcuts to Reorder Tabs extension in your Chrome desktop browser.
Once you install it, that’s it: You’ll have those exact same tab-shifting keyboard shortcuts at your disposal and ready to use whenever the urge strikes. You will have to reload any tabs that were already open prior to the extension’s arrival before they’ll work with it, but from that moment forward, the power will be yours.

Compromising Read-Only Containers with Fileless Malware
Sysdig’s Nicholas Lang describes how to attack a container with a read-only root filesystem, and gives an example of attacking an in-memory data store (Redis) with fileless malware that executes in-memory.
Basically the trick is to use shm / tmpfs which lets you create a mounted file system that uses virtual memory instead of a persistent storage device. You can download your malware or shellcode to tmpfs and then execute it from there.
