While your point is valid, it makes an even stronger case that it should be easy to uninstall

And what about for users that either can’t find this uninstall script or wouldn’t know how to read it or what the contents mean? While I think you do have a point, we also can’t assume that the uninstall script really would’ve removed all traces.

I think it’s worth mentioning also- 8 GB ram on a Mac is not the same as 8 GB on a windows OS machine, given the poor state of windows as an OS as of the past few years.

This comment is so spot on, it’s also big in military circles, especially over past 15 years. It can even be said that frequent (over) use of acronyms is based in insecurity

On newer laptops, and I’ve seen this specifically on thinkpads) if the power supply you are using is not the correct wattage, the system will throttle down significantly. I started noticing this by looking at windows task manager and noticing the CPU would not scale above 0.8 GHz. Not sure if Chrome responds in the same way, but it’s worth looking into. Fix was easy, just get a proper wattage power supply (i went with oem)

Amazing, perfect app! I use it frequently, and I love the response I get from customers or friends whom I turn onto it (or install it for). I also encourage others to donate to this developer. The sad thing is casual users would not even think of donating as they assume this type of feature should be (properly) built into the OS; so I’ve made sure to donate on behalf of users I’ve turned on to Everything. Great app!

This is correct, I also discovered while preparing several ThinkPads for a customer based on a Windows 11 image i made, that even if you have bitlocker disabled you may also need to check that hardware disk encryption is disabled as well (was enabled by default in my case). Although this is different from bitlocker in that the encryption key is stored in the TPM, it is something to be aware of as it may be unexpected.

I’m pretty sure this has changed now, but when I first looked at OBS versus vmix, OBS did not have good NDI Support. Since the twice a year video production I put on is kind of like a hobby although I get paid, I just went with VMix and haven’t looked back. (Video is not my main job)

This is absolutely correct, VMix is excellent software. When you pair it with the correct hardware even low cost hardware, it is very stable and reliable (and powerful). it’s also very reasonably priced, for one particular client twice a year I do a large 2 to 3 day livestream. We buy two copies of their $50 a month pro version (by default it is not a reoccurring subscription), each event. Every aspect of vmix can be automated or scripted, and they have a very easy to use XML based API (I can code but I’m definitely not a coder). Over the years we’ve built some incredible automated graphics for displaying on large billboards at the event, as well as using the second copy to produce the livestream where we pull in five professional ptz cams (via rtsp) and 2x sdi video feeds (via a capture card). We also use the NDI app on two iPhones to add their video into the mix (using the built-in vmix scripting, when someone presses the send button in the NDI app, V-Mix notices the audio level going above zero, and switches that live video feed into program). Note to do ndi over iphone wifi we use a dedicated ruckus R610 access point with no other clients on it, the video has ZERO latency, and amazing 4k quality). We also use companion running on a raspi5, connected to 2x stream decks, so that the entire set up can be controlled via the stream deck buttons.

i'm not saying that, I was asking more of a general question, others were saying that multiple carriers were having issues (w the only proof being downdetector and their incorrectly scaled Y axis graphs)

i know alot are joking / sarcastic about its a cyber attack- that said, Wouldn't it make more sense that whenever there is a "cyber attack" its more likely it would only affect one provider? ie, each has to have different systems / security postures ect, such that a non-public vuln useful to attack Verizon would likely not be exploitable/exposed at AT&T (or vise versa)?

Ive been seeing more of those prove your human pages as well, but I generally assume they are there to combat a DDOS or other type of attack (or maybe ai/bot). I remember how annoying it was combating DDOS attacks, or hacked sites before Cloudflare existed. I also remember how annoying capcha s were, everywhere. Cloudflare is not perfect but net, I think it’s been a great improvement.

Does it matter that AI hardware has such a shorter shelf life/faster upgrade cycle? Meaning we may see the ram chips resold/thrown back into the used market quicker than before?

Another method that most cameras support (if you want the bare basics of record video/audio) is accessing an RTSP stream from the camera. In fact RTSP streams are the primary way you get video into frigate specifically. Some of the more fancy cam manufacturers (axis), are just now starting to support encrypted RTSP , but most of it is unencrypted. you can enable authentication, however in general if you’re doing this over the Internet you do it over a VPN via un encrypted rtsp

This! I manage about 70 CCTV cameras, over the past 15 years. Partially as a hobby. and axis cameras are the best bar none. They are expensive, but if you don’t have a need for the latest gen axis, then eBay is your friend, along with one or two generation prior of axis current gen cams. They are just very well thought out in terms of installation, and ui/operation. Axis is among the most responsive to security issues (which mostly can be negated by controlling your cameras at the network level through vlans and firewall rules). They have a very intuitive web based UI, for example one well thought out ability is through events/rules- you can add a physical SD card into the camera and set up a rule that if the video feed is not being accessed ( set a inverse trigger for “live stream accessed”) then start recording to the on-cam SD card (i.e. your NVR has gone off-line or a network issue is stopping the feed, then you have onboard storage saving that video). That’s just one example.

APC UPSes that support their network management card add in - then the cards can frequently be purchased on eBay for $30-$100, you have to make sure the UPS supports the card, but they are excellent. Model numbers like ap9631 (if i recall). I run about 10 of them across different locations and they work great , some of them for 8+ years now. ( about a year ago when I got a new ups, Apc still offered the older firmware for download, however after a certain FW version it started going to a cloud subscription model - so be sure to keep the old firmware. If you’re worried about the firm or not being updated on the non-cloud version, just be sure to vlan/firewall control access to them which you should be doing anyway)

Assuming my calculation is accurate, 90,000,000 hours of video using around 30 PB comes to an average bit rate of about 760k. (Hard to guess though bc I doubt they’re using up all the space they provision day1)

So my guess is either CCTV type of footage where there’s large gaps of motion / high GOP / big codec gains - or something like desktop recordings which are generally very low bit rate even though they can be high res. At that bitrate I can’t imagine it’s something like YouTube video. (Unrelated to the bitrate maybe it’s something like all older public domain videos). I would love to have an idea of what type of videos they are using (just out of curiosity)

bobbob1921 — Wed, 20 Aug 2025 18:51:05 +0000

I’ve never understood why there isn’t an easy way (ie that never expires) to use certificates or otherwise encrypt communications. I’m mainly referring to unique or internal use cases where the complications around certificates expiring has made it so that those communications end up unencrypted (SSL disabled). I guess what I’m saying is I’ve come across many cases where even bad encryption is better than plaintext, yet plaintext has to get used because of some element of certificates expiring needs renwal. Even bad or easy to crack encryption is better than plain text, yet I totally get why many scenarios end up using plain text (i’m talking in an internal or home lab type set up). I understand why public facing certificates need renewals

bobbob1921 — Thu, 31 Jul 2025 17:06:33 +0000

I may be misunderstanding this, but as I recall originally the only way to run unifi was to have self hosted it through an app on a Windows machine on your network, then it went to the cloud, then cloud only, and now it seems to be coming back to self hosted? Good if so. (UniFi is their app/system to configure your ubiquiti network devices and to gather stats from them, it really did change the networking industry for such a low cost product at the time)
