bobbob1921··on An interactive tour of the spanning tree protocol
I actually think they’re pretty nice even when I was viewing it on a restricted resolution device like an iPad mini, it’s not apparent at first but he does include a check box that allows you to turn off the stickiness of the animations, it’s a few lines or paragraphs below the first animation in the body
bobbob1921··on How to Build a Minimal ZFS NAS Without Synology, QNAP, TrueNAS (2024)
This reply is exactly right about using enterprise drives (hdd), and ideally SAS. Note the power usage of SAS vs sata for an identical drive make/model is very small sometimes 0.5 W to 1.5 W at idle (idle power draw is what matters for spinning HDD’s as underload it doesn’t increase much and idle is what you’ll be at 98% of the time). Also enterprise SSDs are much better than consumer SSD‘s for ZFS, and be aware that when you get above the 4 TB size SSD drives frequently use more power than HDD drives (i’m mainly referring to enterprise non-consumer level drives as that’s all I run for 100s of disks across many zfs systems over past 15 yrs).

Also something people forget for home nas or figuring out cost for a nas, the power draw of the entire system times your electricity price you then have to multiply this times 2x to 4x times if your climate requires cooling air conditioning of any kind

bobbob1921··on Resetting Xbox
This is absolutely correct, I game on Xbox pretty much every day or every other day, I have been with Xbox since 360 or whatever the first one was called. I am still constantly confused by the naming. There also was another revision to the top of the line Xbox series X and the Xbox series X digital edition. I can’t imagine someone looking at the naming scheme pre-release and saying yes, let’s go with that.
bobbob1921··on PeerTube is a free, decentralized and federated video platform
I agree this is a real issue, however hopefully a solution is that creators will upload their videos to both sites (ie YouTube is their primary but also upload to peertube at the same time) which is pretty easy to do and eventually a site like peer tube might reach that critical mass with enough content
bobbob1921··on Sixty percent of US consumers say 'AI' in brand messaging is a turnoff
Good point, but seriously why are the menu options so frequently changing?? (or is that just more BS to delay you further)
bobbob1921··on Indoor Wi-Fi Roaming with OpenWRT
I do a lot of work on very large Wi-Fi networks (i.e. hotel/apartment complexes with 80 to 500+ access points), for a very rough quick test of coverage quality and roaming performance, find a Ping app for your phone that allows you to set a super low interval (i.e. time between pings sent), and ping your gateway router (i.e. 192.168.1.1) and while that is running walk around your home/location. It’s important that the Ping app keeps sending pings even if they drop, i.e. it should just look like a waterfall/constant stream of fast pings that show you red/green pings and ideally a summary at the end. On iOS the app I tell people to use is called “Ping” with a blue icon, I usually have to share the link to the app as there are several with this name (I’m not on my phone currently or I would share the link) there are several ping apps that do offer this fast ping feature.
bobbob1921··on New 10 GbE USB adapters are cooler, smaller, cheaper
in the lower end space kind of, however in many respects no they don’t. Ubiquity would be their main competition, but ubiquity equipment is cloud first whereas a strong point of mikrotik has been that you do not need a centralized cloud controller (ie local first). Also in terms of the vast capabilities of mikrotik equipment at its price point, no there is absolutely no real competitor. (Maybe PFsense is the closest competitor with strong feature set)
bobbob1921··on New 10 GbE USB adapters are cooler, smaller, cheaper
I use mikrotik equipment extensively (as in hundreds/ thousands of them over the years), while I disagree with a lot of of this, the post is absolutely correct about the ridiculous password on a sticker requirements they introduced a few years ago. The pw text is incredibly small and the way it’s printed (dpi and font) makes it very difficult to differentiate certain characters. Also the way you initially connect to them when they’re new out of the box to then enter this obnoxious password has several issues/challenges. It used to be so easy and convenient to configure brand new mikrotik devices in the past, and now it’s become a task I dread and has even caused us to buy non- mikrotik gear in several cases.
bobbob1921··on Samsung Magician disk utility takes 18 steps and two reboots to uninstall
While your point is valid, it makes an even stronger case that it should be easy to uninstall
bobbob1921··on Samsung Magician disk utility takes 18 steps and two reboots 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.
bobbob1921··on People inside Microsoft are fighting to drop mandatory Microsoft Account
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.
bobbob1921··on HP trialed mandatory 15-minute support call wait times (2025)
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
bobbob1921··on Microsoft forced me to switch to Linux
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)
bobbob1921··on Microsoft forced me to switch to Linux
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!
bobbob1921··on Microsoft gave FBI set of BitLocker encryption keys to unlock suspects' laptops
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.
bobbob1921··on OBS Studio 32.1.0 Beta 1 available
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)
bobbob1921··on OBS Studio 32.1.0 Beta 1 available
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.
bobbob1921··on Verizon outages reported across U.S.
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)
bobbob1921··on Verizon outages reported across U.S.
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)?
bobbob1921··on Cloudflare outage on December 5, 2025
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.
bobbob1921··on Samsung's 60% DRAM price hike signals a new phase of global memory tightening
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?
bobbob1921··on Power over Ethernet (PoE) basics and beyond
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
bobbob1921··on Power over Ethernet (PoE) basics and beyond
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.
bobbob1921··on More random home lab things I've recently learned
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)
bobbob1921··on Building the heap: racking 30 petabytes of hard drives for pretraining
Thanks to op for actually replying to the various comments here - really appreciate that (and for the initial of course!)
bobbob1921··on Building the heap: racking 30 petabytes of hard drives for pretraining
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··on Show HN: Anchor Relay – A faster, easier way to get Let's Encrypt certificates
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··on Ubiquiti launches UniFi OS Server for self-hosting
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)
bobbob1921··on Sign in with Google in Chrome
While I agree with the 50+ comments I’ve read here, I think the point is being missed (or I just haven’t gotten to this comment yet) - these super annoying pop-ups should only be a thing AFTER you’ve clicked on login or register. In fact they shouldn’t appear and should instead just be a button the user can click if they wish to use their Google account as the login device for XYZ site. In other words there’s no reason for these to appear when you first visit a webpage, they should only be relevant when the user has taken action specifically to login, or is looking to register an account at xyz.com

It’s as if someone at Google saw the whole cookie banner -> accept cookies fiasco and said wow this seems like a good idea let’s add our own

bobbob1921··on Show HN: Appstat – Process Monitor for Windows
Thanks for offering this for free! it looks great-

why are you distributing this as a .msixbundle? Ive never seen that before (perhaps im un-informed though), As I don't have the Microsoft store I was expecting a .exe (and it appears to install a .msixbundle app via powershell ill need to first install the windows app sdk as well - win11). Is this intended? thanks
