I am not living in the US and am not aware of these laws, but they do make sense in the wording above. In the story these comments refer to the driver had no real place to stop his truck and I believe he was justified in going slow on a rai

If someone feels safer driving slowly they are completely in their right to do so even if it is a detriment to others. They should if at all possible let others pass them and definitely not prevent such passings but it is not always possibl

If you only append you do not get the effect that you want, you actually need to send the writes as a large consecutive write for the SSD to do what they want in this paper. If you send many smaller writes the SSD will for sure split them t

The one thing they are saying in that paper is that they make the fs work to have its writes at about the size of the erase group which would in fact help. A problem I can see with using this on large SSDs is that their erase group size is

by baruch 9y ago
An issue with their work for current SSDs is that the write groups they use are about 16MB to 32MB, current SSDs, need far larger write sizes in order to get the optimization they used to get (essentially they tried to fill an entire erase

I've worked on ssd based systems and while we over-engineered our system due to such fears we never saw any device getting anywhere close to its limits and only once did I see an SSD have a media problem (i.e. failure to read data prev

I never had a software development job where optimizing memory consumption and handling large scale data (for whatever definition of large was for that particular system) wasn't a necessity. It was also useful to know when these measur

I use such a thing for a pot on the garden table but a larger drip system for the garden itself. The Blumat doesnt require running a pipe from under the deck onto the table and is movable but does require filling in water every few days.

To counter that, as a former line manager if an employee just came to me and said he wanted a raise I could only give him so much consideration (big company). If he wanted to get more he'd need to have leverage like a competing offer s

I worked for a large company that used thousands of Intel CPUs every year and when we suspected a CPU bug we were mostly brushed off. We had a very persistent person on the team who kept tracking the issue to find correlations and some very

Are there actual examples of green threads that are not cooperative? All the implementations I've seen are cooperative.

Short stroking helps get more performance from the disk, at least in terms of latency. The bandwidth change occurs because the density is fixed and there are more blocks on the outer rings per track compared to the inner rings so in one rev

I've created sortedtar Brewster if this assumption and while it is correct tree benefit is mostly negligible except for some edge cases.

The main problem is not two drives failing simultaneously but rather one failing shortly after the other. The more drives you have the more the likelihood of that increases, the rebuild time also increases with large drives and so you are m

Adam Leventhal uses the wrong interpretation of the BER value so I wouldn't take his words at face value. The whole argument of Adam is by the disk BER and not by density. I do assume though that the RAID array does media scrub (BMS) p

by baruch 10y ago
May as well ignore the "RAID is dead" screams. They are only FUD. Do make sure to run the scrub periodically though, that's the real defense against rebuild failures.

An HDD/SSD without ECC will not work, and wouldn't have worked for a long time now. Many of the reads performed will require some ECC use. ECC is always written alongside the actual block and the overhead for ECC is the reason for

They do. You get an ack for a write before it reaches the media as long as the supercaps are deemed ok.

So the next step is to crowd source solving NP hard problems by turning them into game problems and let people solve it in many different ways. It's worth knowing how to reduce a problem (say traveling salesman) into bejeweled and then

I'm looking at building my own home automation, the PIR sensors are fairly heavy on power and in order to ping them fast enough I need a fairly large battery or hook up the sensor to electricity. If I can replace that with a device in

You have either brute force with more characters or if you have a file in there with a known content there is a known-plaintext attack on zip encryption. I've used it once and it worked nicely but it's rather tricky to find anothe

On the servers that I use the server will log to ipmi sel only after a threshold but the Linux OS will get an MCE for each error so a monitoring tool can detect and alert even before the BIOS logs anything.

It can mitigate the DoS if you have enough spare RAM. if you are right on the edge that removed RAM will turn into an OOM condition and will become a DoS.

If you get any response from disk vendors I'd be very interested to hear about it and be somehow involved. I've been asking them similar things for some time and got no response beyond a "we'll take a look" and neve

In the long run that may be true, but the same things they talk about (minus the mechanical head changes) will still hold in SSDs. The background activity is even worse for SSDs and the tail latency still very much exists. Essentially the p

A big thing they are saying in the paper is that they want to see data center HDDs that care slightly less about their medium error rates and opt to give better areal density and more consistent tail latencies and let the system above it to

by baruch 11y ago
They are saying the paper they want arms and platters as it's more economical. An HDD is cheaper than an SSD of the same capacity at four to ten times and I don't think the electricity cost will offset this if you care more about
