BitTorrent Performance Test: Sync Is Faster Than Google Drive, OneDrive, Dropbox

Bengie Re:Trickle (71 comments)

I have a 50/50 dedicated fiber connection with a rock solid 0.35ms ping to my ISP and a solid 8ms ping to drop box servers. Why is my connection only doing 10mb/s with DropBox and getting packet-loss, while I can use BitTorrent at 45/45 up & down at the same time and not have loss or latency? DropBox seems to have the bandwidth, but the quick bursts are wrecking havoc with my ISP's traffic shaping via their Cisco router. The way Cisco is calculating the mb/s seems to be via some sliding window, which allows a quick spike of a burst to happen in the first 1/4 of a second, but then clamps down. Because my network latency is so low, the TCP stream can ramp up really fast. Once the Cisco router clamps down on the connection, I'm already uploading nearly 100mb/s and TCP can't back off in time before loss happens.

The reason loss occurs after the clamping is because my ISP uses small buffers. They don't like buffer bloat. My max latency to my ISP before loss starts to occur is about 10ms. Since the connection is dedicated, and their trunk is sized about 3x more than peak bandwidth, it's normally not an issue.

This wouldn't be an issue if DropBox transferred the data as a single stream, but instead does a very jarring start/stop cycle, which causes my bandwidth to get very spiky. I'm thinking of enabling traffic shaping on my PFSense box, but I really don't feel like messing with it quite yet.

I guess the actual problem really is the Cisco router, but DropBox is still incredibly slow.

BitTorrent Performance Test: Sync Is Faster Than Google Drive, OneDrive, Dropbox

Bengie Re:Fancy version of FTP (71 comments)

Let me know how well FTP scales as you add more nodes, and how it allows you to keep your data separate from other people's data while still allowing you to use their node for storage.

BitTorrent Performance Test: Sync Is Faster Than Google Drive, OneDrive, Dropbox

Bengie Re:Trickle (71 comments)

They are not designed to not use all of your bandwidth, it's that they can't. I've tested DropBox, and it breaks up the file into chunks and uploads them synchronously using REST calls. This meant my connection was constantly bouncing between 0% and 100%, causing bursts of packet-loss because it never gave TCP enough time to level out. BitTorrent on the other hand is great at not hosing my connection. I can run it near 100% and it will back-off as it detects latency going up, preempting the need for packet-loss to signal congestion.

Judge Says EA Battlefield 4 Execs Engaged In "Puffery," Not Fraud

Bengie what? (67 comments)

Even if they weren't intentionally lying, telling investors information that is effectively false is at best being self delusional, which is professionally irresponsible.

If I didn't lock the bank vault at night, for several years in a row, and my sole job was to protect the vault, then someone broke in and stole everything, could I get away with "puffery" because I told others, with confidence, that I as protecting the vault?

How about a surgeon who is asked to do a surgery, but by no means should because he had no experience. But because the surgeon felt "optimistic", someone died. Ohh, it was just "puffery".

Call it what it is, willfully ignorant lying.

Astronomers Find Brightest Pulsar Ever Observed

Bengie Re:it's an electric universe baby (55 comments)

I can't even find any references of "Red Shift" being discredited except by fringe crazies. I have found articles talking about a certain amount of uncertainty that may need to be adjusted based on our findings of space expansion, but nothing that says it's "wrong".

Samsung Acknowledges and Fixes Bug On 840 EVO SSDs

Bengie Re:Classic Samsung... (99 comments)

When looking up Samsung products, I see few complains and many long time users. I can't say this is the case for many of the other options. Not only does Samsung compete with price for SSDs, but they have the best track record of them all, even Intel. At least the Samsung 850 has a 10 year warranty. If you're still using that SSD 10 years from now, that would be sad.

Shooting At Canadian Parliament

Bengie Am I reading this wrong? (447 comments)

"and shot a soldier with a rifle."
Is it ambiguous for others of whether the soldier was shot with a rifle or the soldier with a rifle was shot?

When I read it in my head, I naturally want to place a pause after "soldier", so I assume it should be more like "and shot a soldier, with a rifle".

32 Cities Want To Challenge Big Telecom, Build Their Own Gigabit Networks

Bengie Re:and the cities are... (173 comments)

Most people I know either still live in the State or moved away for their first jobs, but have moved back to start families. Since the state covers nearly the entire cost of the Universities for in-state citizens, it doesn't really matter where they move, as long as it's still in the state.

32 Cities Want To Challenge Big Telecom, Build Their Own Gigabit Networks

Bengie Re:Boston (173 comments)

The average GPON rollout is 3-4 years for a small ISP that has a lot of overhead. The larger you get, the more efficient you get. Even Chattanooga EPB broke even at the 3 year mark. They had completely paid off the entire fiber install and where then turning a true profit. Which is why they lowered their 1gb service from $300 to $70, because they no longer needed to pay anything off.

32 Cities Want To Challenge Big Telecom, Build Their Own Gigabit Networks

Bengie Re:Boston (173 comments)

Verizon actually acknowledges that FIOS increase revenue and reduces costs. I'm guessing the problem is running fiber has a 2-3 year break even, which is too long for a public company worried about quarterly returns.

Safercar.gov Overwhelmed By Recall For Deadly Airbags

Bengie Re:No problem (119 comments)

Airbags are for your head, seat belts are for your torso. If you enjoy slamming your head into your steering wheel, go ahead and disable your airbag. Even more fun are videos of an asymmetric head-on collision that favors one side over the other. The test dummies slam their heads into the frame of the car unless you have properly working forward and side airbags.

32 Cities Want To Challenge Big Telecom, Build Their Own Gigabit Networks

Bengie Re:Boston (173 comments)

My ISP ran fiber to every house in the city, customer or not. Cheaper that way. Even customers that are several miles outside the city limits got fiber, all on the ISP's dime, no local, state, or federal government grants or loans. Verizon is just greedy.

Debian's Systemd Adoption Inspires Threat of Fork

Bengie Re:That's all we need ... (545 comments)

FreeBSD is written and used by Sysadmins. Maybe the Linux people will learn to appreciate good design from the get-go instead of "Lets fork it!". A well designed system should work within the 80/20 rule. A single distro should be used by 80% of the user base, if it not, something is wrong.

Ubuntu Turns 10

Bengie Re:Unity is rubbish. Systemd is rubbish (110 comments)

"Mainstream" in this context is the average homeuser demographic, not the custom workstation demographic. Show me a popular desktop or laptop computer targeted to parents, grand parents, or gamers that have Linux installed by default.

Be True To Your CS School: LinkedIn Ranks US Schools For Job-Seeking Programmers

Bengie Re:Missing the point (128 comments)

I don't have a CS degree, but I have a similar one. When I was a Freshman back around 2004, one of the fist things I learned in 100s level class was how to use parameterized inputs, and how not to designs your SQL queries to be injectable. That information alone could save the industry billions a year. Bad schools or bad programmers, not sure which.

Be True To Your CS School: LinkedIn Ranks US Schools For Job-Seeking Programmers

Bengie Re:In theory (128 comments)

Most trash I know has a grasp on practice, but doesn't understand theory. They have hard time understanding edge cases or scaling. The opposite is knowing theory but no practice, but anyone can get practice. It's hard to get theory self taught, the internet is sparsely populated with good theory and lots of bad ideas. Plenty of code examples.

Resolving IP to MAC address across a router

Bengie Bengie writes  |  more than 7 years ago

Bengie (1121981) writes "From what I know about networks, you can't find out the MAC of an IP across a router. At some point I stumbled across a program that does just this. The only google hits I get talk about Netbios. Being able to do this would help out IT dept because our back-up registration page pulls MAC info from our DHCP server, but the DHCP database only syncs with our back-up database every 24 hours. If we build a new computer to replace an old one, our registration page can't get the new MAC for the Wake-on-LAN info until 24 hours later. We could use netbios if we had to, but that's kind of shady and won't work for our Mac computers since they don't have netbios. Is there a way of resolving the MAC of an IP across routers?"
