Or perhaps my channel has attracted the attention of a YouTube employee, that went and reported it themselves.”

Pile Of Garbage posted:so VBScript is being deprecated in Windows 10 and 11. they're relegating it to an optional feature on demand and then at some point in the future they'll remove it altogether: https://learn.microsoft.com/en-us/windows/whats-new/deprecated-features-resources#vbscript. imo it's a welcome change which won't really do much security-wise as powershell is the preffered vector these days but at least it will stop grognard sysadmins from writing and deploying new vbs scripts in TYOOL 2023 (yes these psychos exist, complete sickos). "before being retired in future Windows releases" so those grognards will be able to continue deploying VBS scripts on a supported windows version well into the future but it'll have to be on (checks notes) Windows 10 IoT Enterprise LTSC 2021 (lol) which has extended support until TYOOL 2032 https://learn.microsoft.com/en-us/lifecycle/products/windows-10-iot-enterprise-ltsc-2021

In future releases of Windows, VBScript will be available as a feature on demand before its removal from the operating system. and https://learn.microsoft.com/en-us/windows/iot/iot-enterprise/whats-new/windows-iot-enterprise-ltsc posted:Windows IoT Enterprise LTSC is designed for specialty devices and use cases where functionality and features remain constant for the life of the device. These devices are typically found in industries including, but not limited to, banking, healthcare, hospitality, manufacturing and retail. Devices that require regulatory certification and devices that perform a critical business function can't accept feature updates for years at a time. "Windows 10 IoT Enterprise LTSC 2019" is a release of windows "Windows 10 IoT Enterprise LTSC 2021" is a release of windows hypothetically "Windows 10 IoT Enterprise LTSC 2025" could make VBScript optional and "Windows 10 IoT Enterprise LTSC 2029" could remove it entirely. but "Windows 10 IoT Enterprise LTSC 2021" would still be supported until 2032

my favorite dumb website practice is the simulated "allow notifications" dialog inside the website content where if you click deny it closes the fake dialog and does nothing and if you click allow it calls the real browser notifications API. that way they can keep the browser from adding the site to the browser's notifications blocklist if the user wants to deny permission so they can ask again next time. so the trick is to click allow on the fake dialog and deny on the browser's real dialog or even better, just change the browser's default notifications behavior to block by default. i think the fake notification dialogs check the permission status and don't bother showing it if it's already denied

Subjunctive posted:so if not Ubiquiti/Unifi, what’s the hotness for in-wall APs and PoE switches and stuff? Subjunctive posted:the UniFi in-wall APs that are also 3-port switches (one with PoE pass through) have been so handy for getting good coverage in the house and not having to stash little switches in various rooms, but I don’t see anyone else who makes them, least of all with 6E/2.5GbE i have a couple of these but they're Wi-Fi 6 / 1GbE devices with a mediatek chipset https://www.tp-link.com/us/business-networking/omada-sdn-access-point/eap615-wall/ the EAP615-Wall is supported by OpenWRT and trivial to re-flash if you're into that sort of thing. they also have a thicker unit with a qualcomm chipset, but still Wi-Fi 6 / 1GbE https://www.tp-link.com/us/business-networking/omada-wifi-wall-plate/eap655-wall/ personally i'd skip Wi-Fi 6E and wait for Wi-Fi 7. apparently there are products that use mediatek's Wi-Fi 7 SoC in the pipeline. for 2.5 GbE PoE i have a VLAN-capable netgear MS108EUP which is kind of nice for feeding a few APs. if i needed a lot of 1 GbE PoE ports in a rackmount form factor i'd get a refurbished EOL cisco switch from Network Tigers for like a couple hundred bucks. but i also don't mind janitoring the cisco IOS CLI (as long as it's a real cisco catalyst switch and not the garbage cisco "small business" switches). i have a couple of 3560's on UPS/generator power with 5 years of uptime.

Subjunctive posted:interesting about wifi 7! is that going to be backwards compatible, in that Wifi 6E devices will get 6E performance, or will the get whatever they’re getting now? I am quite interested in 6E for streaming to my Steam Deck my understanding is that Wi-Fi 7 uses the same frequencies as Wi-Fi 6/6E, the 2.4 GHz, 5 GHz, and 6 GHz bands and Wi-Fi 7 supports a superset of the modulations supported in previous Wi-Fi standards. so yeah a Wi-Fi 6E device shouldn't really care whether it's connected to a 6E or 7 access point. where things might get weird is if they make cheapo access points that don't have enough radios to support all the bands or something, like i think the Wi-Fi 6E access points need three separate radios to support simultaneous operation on each of the 2.4, 5, and 6 GHz bands. oh lol and i missed that intel apparently already launched their client adapter https://ark.intel.com/content/www/us/en/ark/products/230078/intel-wi-fi-7-be200.html looks like it's already on amazon and aliexpress if you search for be200ngw quote:the thing I love about the UniFi in-walls is that they’re also switches so I get a few extra ports for things, but those need to be 2.5GbE for it to matter to the stuff in the office. maybe I stick the AP in the ceiling on its own run, and just use a normal switch in the office yeah if you have two cable runs an access point and a desktop switch could work? like an unmanaged 5 port 2.5 GbE netgear MS305 is a hundred bucks

In anticipation of hitting that milestone, he was preparing to announce that he’d have a web-only version of the platform ready for limited testing by mid-January. If all went according to plan, he’d then release a Spoutible app for phones and tablets in the spring. When I said that timeline seemed ambitious, he assured me that the work on the frontend would take only a few weeks. He’d licensed some off-the-shelf code, composed primarily in PHP, that provides a close facsimile of Twitter’s user interface, and he planned to tweak that template to suit his needs. welp https://www.troyhunt.com/how-spoutibles-leaky-api-spurted-out-a-deluge-of-personal-data/

lolhttps://lemire.me/blog/2023/03/15/precision-recall-and-why-you-shouldnt-crank-up-the-warnings-to-11/#comment-651471 posted:Back when I worked on Windows Vista, the Windows team introduced static analysis tools that operated in conjunction with source code annotations. The vast majority of flagged issues were false positives, but the problem wasn’t just wasted time from investigating non-issues. Some manager had the brilliant idea of outsourcing all the “trivial fixes” for issues flagged by static analysis to a large IT contractor in India. You can probably guess how well that went. Novice programmers completely unfamiliar with one of the world’s most complex codebases introduced so many bugs (I wish I had statistics), which the Windows developers then had to fix, that I’m sure it would have been cheaper to leave the investigation and fixes to the original developers. The original “bugs” were mostly illusory, but the bugs introduced in the “fixes” certainly were not. (Not that I have anything against static analysis: the Vista codebase was far more robust than XP as a result. But this was definitely the wrong way to implement it.)
