Incidentally if any fans of original 1989 TV Woman in Black that terrified a generation want to get a Blu ray copy buy it now while you still can. Released by Network who have gone into liquidation. Copies still available via Amazon and elsewhere but once they sell out that's it. This was a stellar horror TV version, and Blu Ray is fab. It's also available on DVD which will also go out of stock once sold. #TV#80sTV#Horror#SusanHill#WomanInBlack#DVD#BluRay#Network#NetworkDVD#NigelKneale
I was stupid today. I was wondering why on Earth my Ethernet connection between my PC and the home server was stuck on 100Mbit/s. I spent hours trying to find a software solution. Then it hit me, maybe the cable is incapable of transferring at faster rates? Yes, yes it was the cable... I feel so dumb for not checking my cables before this...
Had lunch with a prospect today. When we got farther along in the conversation, he asked about my pricing. I told him, and his very next question was if I had any other pricing or discounts. Not a good sign. I know my pricing is fair and competitive, and I bring real value. If he doesn’t like the price, it’s better for both of us if he never follows up.
To Understand the Upcoming Republican Primary, Follow the Dark Money
Chris Jankowski, CEO of the pro-#DeSantis group Never Back Down, documented as the “settlor” — effectively, the creator — of the #Marble#Freedom#Trust, a massive pool of cash #Leonard#Leo is using to finance conservative advocacy groups.
In 2021, the trust received $1.6 #billion from the sale of Chicago businessman #Barre#Seid’s surge-protector empire, constituting the largest known #dark#money donation in history and leaving Leo in control of an unprecedented political advocacy fund.
The role Jankowski played in developing the Marble Freedom Trust has not previously been reported, though he has for years served as a consultant for Leo’s dark money #network, which played a central role in flipping control of the #Supreme#Court and building its 6–3 conservative supermajority.
I had no idea that the energy network in Lebanon was in such a poor state. However, solar panels are allowing those with enough money to bypass expensive, polluting diesel generators in favor of clear, reliable electricity. I also appreciate the point at the end of the article about community projects, which I think is very important.
Looks like you still can't really host your public site exclusively on #IPv6, the adoption is too low. That's a shame, it would be a bit cheaper for me. #Network#WebDevelopment#Hosting
At the end of #office day (we have hybrid work as default) coworker from other department went into our room. They said something about good, positive day and optimism. They looked at people in our room and finally at me.
"It's really good, you are here today and yet we didn't have any #network outage."
This way I learned they think I have some kind of #curse on me, which causes network failures in my presence... :blobcatjoy:
"(W)hat we are witnessing is the wealthiest companies in history (Microsoft, Apple, Google, Meta, Amazon …) unilaterally seizing the sum total of human knowledge that exists in digital, scrapable form and walling it off inside proprietary products, many of which will take direct aim at the humans whose lifetime of labor trained the machines without giving permission or consent."
It does seem worse now that it's just a handful of companies using novel tech to isolate & gatekeep the work of others, instead of handfuls of industries and/or nations.
Things that are hidden in plain sight can be revealed by slowly removing the 'noise' over time, until there's nothing to hide behind.
Tools of #oppression will ultimately be used to destroy oppressors.
Is your VPN slower than you wish it was? Are you using a firewall to create point-to-point VPN tunnels? There’s more going on in a VPN than meets the eye.
Outline:
bits and bytes
IP overhead
encryption overhead
blank space, interleaving, time sharing
processing time
bits and bytes
Let’s start with bits per second (bps) vs bytes per second (Bps). Assume no overhead, and a 100 megabyte file (100MB). At 100 megabits per second (100Mbps), it will take 8 seconds to send a 100MB file, because it’s 800 megabits (800Mb) of data.
IP overhead
Now let’s add overhead. We’ll assume TCP/IP over Ethernet. Although a standard Ethernet frame can be up to 1518 bytes, real world statistics over time have consistently shown that the average Ethernet frame is 240-250 bytes. It’s been true for many years. I’m not going to prove it here; if you want to see for yourself just do a search on the phrase “size of the average ethernet frame” or similar wording. The point I want you to understand here is that the ratio of overhead is much higher than most people think. Overhead is not inconsequential – it is significant, across all traffic types.
encryption overhead
Additional overhead is created by encryption. Some of this overhead is created by the security handshakes, checksums, and other protocol elements. The encrypted data itself will be somewhat larger than the cleartext data, for two reasons: the encryption process will add some information to the file, and also many encryption methods involve padding.
blank space, interleaving, time sharing
There are additional factors that increase the transmission time. If you’re interested in the subject of data throughput calculations, do a search for “interframe gap” (IFG) in Ethernet systems. There’s a small blank time between each frame. Also, when we send VPN packets over the public Internet, our encrypted VPN packets will be interleaved with traffic traveling on the same carrier’s backbone to and from other endpoints. We’re sharing the carrier’s bandwidth with other users on the backbone, even though we have a dedicated tunnel between our two endpoints. This is because it’s a virtual dedicated tunnel, not a physical dedicated tunnel.
processing time
There is more time involved, too, than just transit time. At the sender’s end, it takes time to encrypt the data for our VPN tunnel, and the receiver takes time to decrypt the data. How busy is the sender’s encrypting CPU? What else is happening in the CPU? How much multitasking is taking place? Note that in some circumstances, the data is double-encrypted: once by the computer (think HTTPS, if being used over the tunnel), and again by the firewall.
SUMMARY
All VPNs are slower than non-VPN traffic. Even if the sender’s NIC is communicating with the firewall at 1Gbps, and even if the firewall’s WAN port is passing data to the ISP’s gateway at 1Gbps, the actual data throughput is much lower. In other words, “bit rate” and “data throughput” aren’t synonymous.
If VPN data throughput is unsatisfactory, remediation steps can include:
a firewall with a better processor (at both ends)
a firewall with more RAM (at both ends)
limiting other traffic on the firewall that handles the VPN (i.e., segregated traffic, which will mean two Internet connections) to reduce the load on the VPN processor to essential traffic.
Just had a new Triton Router ( #woodwork not #network ) delivered and I'm slightly confused by the choice they made. 3 Collets included, 1/2", 6mm and ... 12mm - 8mm I could understand, but 12mm just baffles me.
It's been such a long time since I had to do anything networking-related; probably when I was studying for my #CCNA many years ago.
Found myself recently having to delve into #Cisco Packet Tracer to help plan and configure an enterprise network with VLANs, SVIs, routing protocols and all that fun stuff.
It was at this point the true depth of all the stuff I used to know but have since forgotten came to light! Nice to re-visit those skills, though.
In my opinion, the future growth rate of the #Fediverse will chiefly depend on 4 factors (hypothesis):
the ease with which #newbies can find the best fit of platform and instance, as well as content.
if the speed of growth can be matched with the evolution of intra-instance and inter-instance moderation procedures and "institutions" to moderate cultural clashes
the ease of account mobility, preserving the built...
...#network (which constitutes the
natural, personified "#algorithm") and the created content fir those that wish to preserve it.
Will big instances be bought up by corporations and oligarchs on a significant level, so as to influence the development of the #Fediverse significantly?
Anybody know anything about BlueSky social? I get Nostr, that's just Jack Dorsey, and Crypto Bros gonna Crypto, but why is BlueSky trying to create ANOTHER distributed social network when we already have one that WORKS GREAT and WITH OPEN STANDARDS UNGH! :)
I'm guessing this is about $#!@# money. Some idjit saw Twitter goes toes up and smelled an Opportunity?
@spreadmastodon anyone have a theory on why facebook beat myspace? i’m working on teasing out why social graphs rot over time, and wondering to what extent it’s a function of the features of a service vs. the stewards of the social graph vs. something else…
MS got 'cool' status with young people, but the problem is, they grow up, and new young people arrive in periodic waves like clockwork.
By continually deceiving users & others, FB's pivot from 'College X' to another college, then any college, etc. just allowed the 'old' MS crowd to have an 'adult' place to go, and continue their perception of being in the In crowd.
This allowed the latecomers to bandwagon onto the trend too, and there were no other serious competitors, so (social) #network effects began pumping.
There was no real utility there, so you only need to look at fads & crowd behavior like #FOMO (and the Vulture Class who monetize it) to understand the success/failure of these bubbles.
#Physics is where I started and someday want to return, but currently focused on our great task.
New to #Mastodon, hoping to find a place where people can connect more authentically than #LinkedIn, without the algorithm or the corporate hype machines. #EnergyMastodon
