  • FCC will vote to scrap telecom cybersecurity requirements

    Jump

  • it doesn't matter, our insurance company has more strict requirements. all it ever is for FCC, CISA, NIST, etc is someone "attesting" that we meet requirements

  • thank you! not a new form factor just cloth covered now

  • It is considered a fail, and then inputting passwords in the form is a super fail.

  • we do monthly phishing tests and some of our people are so bad that we put in the test email "this is a phishing email, do not click sign in" above and below the sign in box and they still give creds

  • Key Camp Pendleton document has no approved artillery firing locations west of I-5

    Jump

  • What I am personally curious to see is if this was ever completed:

    a waiver from Pendleton’s Range Operations Division — call sign LONGRIFLE

    It seems they had a form waiver, that likely would include risk assessment. The article later stated that the military appeared to be following procedures outlined in the waiver/by the Range Operations Division, specifically when all firing ceased and a root cause analysis launched after the premature detonation.

  • Is it so hard to get Nvidia GPUs working with Linux?

    Jump

  • I have multiple linux computers, from servers to a surface tablet, i am able to use all different generations of all nvidia, both permanently installed, and eGPU. It is not without any issue, but it works and is usable.

    For me issues stem from x11 vs wayland (work computer is ubuntu due to company policy), or egpu shenanigans which I feel is platform agnostic

  • Controller question

    Jump

  • ELRS is for the Tx (controller) to Rx (drone) protocol. Whatever drone you buy needs to include the ELRS receiver or you need to buy a receiver to add.

    You will want to setup a profile that disables the ELRS transmitter when you decide to use for sim, to save battery.

  • Controller question

    Jump

  • USB-C on the controller. When you plug it in with EdgeTX for software, controller will ask if you want to use it as an USB HID (this would be for gaming), serial (firmware update / telemetry to pc i believe), or mass storage device (adding files for lua scripts etc)

  • Dance of the ages

    Jump

  • thank you

  • Most people seem to assume fire alarms are false alarms. Is that how it's always worked? What can be done about it?

    Jump

  • It may have been a rate of rise vs a hard upper limit for the heat detector. If it was, about 8-10°C / 15-20°F change per minute would set it off. Makes sense for it to go off over an oven. The hard upper limit type are single use, I don't know if that causes them to repeatedly go off or not.

    Either way with more regulated short term rentals, a fire inspection would likely have flagged that.

    Jump

  • There is nuance in installing fire alarms, make sure you are using the correct detector type for each area, and installing it correctly.

    I'm pretty sure strong drafts or dusty areas can set it off.

    Also know that smoke detectors and carbon monoxide detectors are consumable items that should be replaced, usually 7-10 years but it should be noted on the device.

    At the end of the day, it wakes you up to check, or causes you to observe for an emergency. Imagine your wake up groggy situation but you smell smoke. Personally I would like that chance to be able to evacuate.

    Do I need the ISPs home router?

    Jump

  • Verizon and ATT just rebrand nokia ONTs and roll some of their own software that is mostly enhanced or changed encryption at L1. Can't speak for Comcast, I only know about the other two as I'm in a smaller ISP that competes with them.

    They use have L2 onts that don't have any gateway functions, just fiber to ethernet with some extra overhead to monitor the connection between the hose and shelf.

    The ONT-on-a-stick units do the same thing, just a more compact and expensive interface that doesn't have great support, unless comcast or running all home run fibers where they can just provide a straight SFP instead of doing any optical splitting.

    Do I need the ISPs home router?

    Jump

  • No, you are likely looking at an ONT (optical network terminal), and it is not a router. Even with a port that accepts the fiber (sfp or sfp+ for 10g) on your equipment, the OLT (optical line terminal) likely will not provide you with service.

    If you were to match the wavelengths the ISP is using you are likely to become a "rogue" on their PON that can knock out service for other customers that share the same passive network as you.

    I make assumptions about you being on PON since you say AT&T, generally all I have ever seen from them are passive networks (one fiber with splitters for 1 port to many customers) unless you are paying extra for "dedicated" ($$$$$) internet.

    If they are using a ONT with an "RG" (residential gateway) which is the typical "all in one" you can request the gateway service can be removed and replaced with a layer 2 bridge, where you're router/firewall gets the "external" addressing and there is nothing being done by the ISP equipment other than sending you traffic and OAM (operations, administration, and maintenance; usually check or alert for light levels, software status, if a part of the ONT fails etc).

  • ELI 5, how can CloudFlare block traffick to sites?

    Jump

  • There are definitely multiple ways they can block traffic to a site, but you have to be sending traffic through them or using DNS from them, or placing your site behind them using them for protection from denial of service attacks.

    Firstly, if you pay or use their free "anti-ddos" services, what is really happening is all traffic to your site is being sent through their network. Should you violate their terms of service, they can choose to terminate that traffic.

    DNS is Domain name service, where I want to visit example.com, and DNS tells the computer to go to 12.34.56.78. The DNS server your computer will ultimately use can be assigned by your ISP, manually configured by your network administrator, etc. One choice you can use, that is regarded by some as a good choice due to response time, is cloudflare. When cloudflare decides to block a site, one method they may use is to redirect DNS replies for that domain to a placeholder that indicates this site is blocked, or reply with NXDOMAIN - Non-eXistent domain.

    An ISP could also choose to buy bandwidth from cloudflare as an upstream provider. For cloudflare enforcing a block, they would redirect traffic destined for any of address they want to a placeholder just like DNS.

    A more aggressive, and dangerous tactic that could cause global outages for a site, would be to falsely claim address as their own to the public internet with Border Gateway Protocol - BGP, then redirect/blackhole it.

  • What does an ISP need to do in order to support IPv6?

    Jump

  • Certain equipment need to support IPv6 in certain ways, but not necessarily be assigned a v6 address. Anything OSI layer-2 or layer-1 will not need to "explicitly" support v6, with exceptions. The network terminal (ONT/modem) usually needs to support v6, as they will generally have security features to prevent a subscriber from using random addresses they were not assigned, or using multiple.

    At a minimum, core/edge routing supporting v6, premise equipment supporting v6, at least one upstream provider or transit provider that supports v6 in combination with diverse peering with v6, and ancillary servers to provide DHCPv6 and DNS6. Generally I would assume a provider adding v6 is going to do dual stack, which is great for usually not being NATed on at least one IP stack.

    What's nice about v6 being so old.. is that a lot of the equipment they are using will support v6. Most consumer routers just need to get a dhcp reply with v6 with default settings.

    We are deploying v6 to both brand new fiber customers and very legacy dsl customers without widespread equipment replacement now, at a US based ISP, but I don't work at Bell or have any idea of what other hurdles they may have that we don't.

    Tesla Diner Drops Most Menu Options And Cuts Hours Just Weeks After Opening, Surprising No One - Jalopnik

    Jump

  • Thanks I hate it

    Jump

  • I work for an telco and I have seen a lot of times that a contract for using preexisting underground infrastructure that have lids like this has a section requiring that they are returned to the same location and orientation when the enclosure is sealed.

    Whoever owns that, municipality or private, will probably take a complaint about it, and may pass it to whoever is responsible or owns the plant inside.

  • RAM

    Jump

  • I am working to decommission a windows server, which is currently using 500gb ram, and i have moved all functions to a different application, same purpose and very similar underlying methodology... 32gb of ram on linux. it's crazy how much bloat windows admins are willing to accept.

  • US judge sentences ex-police officer to 33 months for violating civil rights of Breonna Taylor

  • Missing from headline: "... despite federal prosecutors requesting a 1 day sentence"

    Glad the judge was able to see the absolute ridiculousness of that.

    edit: I thought at first it was 33 years for some reason... sad day.
