DanBlake··on There are no acceptable ads
I hate this shit. Between adblocking and piracy, people are just going to push publishers into a new form of advertising where they don't even know they are being advertised to. This is going to mean more "sponsored posts" on sites you love and less authentic content. Its going to mean your favorite movies crammed with product placement ( https://www.youtube.com/watch?v=nfHuZ5qrYX4 ). Its going to mean a distrust of anything you see on the web much greater than exists today. Its going to mean every product review you read about will be 90% about the affiliate payment they get and 10% because of the product itself.

Ads suck, I agree. I think the major complaint is malware- But that doesnt explain blocking google adsense, which doesnt allow offsite javascript, or facebook ads, or other 'trusted' ad networks. People just remove those ads because "Fuck ads" - Well, thats fine. But those decisions will obviously not just be candidly ignored- Publishers and content producers will react and find new ways to generate revenue where they lost it.

DanBlake··on Rents are plunging in the most expensive U.S. markets
Zumper is pretty inaccurate when it comes to SF I have found. The influx of new residents still vastly outpaces new construction + people leaving SF. As such, rents are not going down. The easiest way to verify this is just to ask anyone trying to rent in SF.
DanBlake··on Amazon S3 and Glacier Price Reductions
Would really like to see some massive reductions in the operation costs and most importantly, bandwidth costs.

The bandwidth costs are so far out of line with what the network transfer actually costs, it just feels like price fixing between the major cloud players that nobody is drastically reducing those prices, only storage prices.

Charging 5 cents per gigabyte (at their maximum published discount level) is the equivalent to paying $16,000 per month for a 1 gigabit line. This does not count any operation costs either, which could add thousands in cost as well, depending on how you are using S3.

There are several providers that offer a unmetered 1gbps line PLUS a dedicated server for ~600-750/mo. Providers like OVH offer the bandwidth for as little as 100/month. ( https://www.ovh.com/us/dedicated-servers/bandwidth-upgrade.x... ) I am just not sure how amazon can justify a 160x price increase over OVH or a 30x increase over dedicated server + transfer.

For the time being, the best bet is to use S3 for your storage and then have a heavily caching non amazon CDN on top of it (like cloudflare) to save the ridiculous bandwidth costs.

DanBlake··on LinkedIn accesses Gmail contacts via ‘auto-authorization’
If you know about browser security, you know that was is being described is just not possible. Likely that the author had authorized some google importer or something, but simply visiting 2 different websites in 2 tabs would not allow this. Just imagine the insanity if it was possible for another site to read from another tab.
DanBlake··on Final – A credit card built for the 21st century
Woops, I meant 1 point per dollar spent.
DanBlake··on Final – A credit card built for the 21st century
This was my thought. I would love to use it, but I am not going to give up my SPG card from American Express. It gives me 1 point per purchase, but by saving those points for first class tickets, I have been netting out at 25 cents per point.

For instance, I just took a first class, round trip flight to Tokyo with my wife. The cost for each one way flight was a bit over $15k. So thats almost $60,000 in flights that I booked for 240k SPG points (transferred to AA with bonus, which then booked with Japan Airlines and Singapore Air). If I had used Final's 1% cashback program, I would have only received $2400.

Seems like a no brainer to skip out on the cooler features to get 25% more value from my purchases.

DanBlake··on RIAA, BPI, IFPI sue largest YouTube ripping site
Whats very interesting about this is the huge implications it could have for adblocking. If the labels win on the 'circumvention' clause, the impact could effectively outlaw adblocking. If youtube can say "you can only access our content with a browser that doesnt save the audio portions of our video" then they can also say "you can only access our content with a browser that shows all ads"

Although google does not appear to be a plaintiff here, they have certainly indicated they could be one in the future ( https://torrentfreak.com/google-threatens-to-sue-huge-youtub... )

DanBlake··on “Sonicwall products are not returnable”
Did you buy it with a credit card? Most of them have additional protections that let you fix situations like this. Not sure if it applies to returns, but for instance I know you get a guaranteed extra warranty with anything you buy with your amex past the manufacturers, etc..
DanBlake··on Running at 150,000 RPM, a tiny motor could help satellites
Correct me if im wrong, but I would assume that the motor must still be 'attached' somewhere, else the momentum would not translate into moving the satellite. (Wouldnt it be akin to having a gyroscope just floating inside of a satellite- Suddenly stopping it would have no effect on the satellite since it would not be actually attached- ala, the fly in a car scenario) - So, with that, if it is indeed attached somehow, wouldn't the friction component still be at play?
DanBlake··on Why I’m Suing the US Government
Unfortunately I believe that even if the suit was successful, we would just see more purchases become 'perpetual licenses', skirting the updated law. IIRC, Tesla was very heavily against letting anyone tinker and went to some extremes to stop it. It wouldn't surprise me in the least to see them make buyers sign a EULA in the future when you go to 'purchase' a vehicle.
DanBlake··on SYN Flood Mitigation with synsanity
Speaking as someone who ran a very popular video chat service that had on average 5+ DDoS attacks a day, I can tell you that the vast majority of our attacks were under 1gbps in size. Usually the 'attackers' would use services you can rent on hackforums for 5-10$/week to 'boot' websites and people offline.

Thats why I was asking about how efficient this was on a per-server basis and why I think a answer would be beneficial. Most DDoS attacks are not the multi-gig reflection attacks you read about and defending against those types of attacks is much more complicated.

Regardless, I am not debating if ddos prevention has to be in depth or not. Im asking how efficient this is on a single server.

DanBlake··on SYN Flood Mitigation with synsanity
I am curious how effective this is at larger synfloods. Obviously when something hits near 1gbps, its game over for any server as that floods the uplink (assuming a standard 1gbps hookup)

How many mb/s or pps can this handle on a average server while still having the server be able to respond to legitimate requests? ( lets say a average server is a quad core, 3.5ghz , 8gb ram)

DanBlake··on “Should you encrypt or compress first?”
My point was never that it was possible 100% of the time. Simply that it was possible some of the time.
DanBlake··on “Should you encrypt or compress first?”
Feel free to upload a 5MB file under your narrow restrictions and I will see if I can reduce it with one of the 20 different compression systems available to me.
DanBlake··on “Should you encrypt or compress first?”
This is literally all I was saying and people went on a downvote frenzy. People are literally saying that a encrypted output can NEVER be compressed. I was saying that it can (although not all the time!) and the gains would be minimal. Ive corrected the first post with the word 'may'
DanBlake··on “Should you encrypt or compress first?”
Here it is encrypted with AES256 - Pass is wasteoftime

http://pasted.co/wasteoftime.txt 4,732 bytes

http://pasted.co/wasteoftime.rar 3,753 bytes

Also, if there is issues with using the 'wrong' encryption, I feel thats kind of a straw man argument. Please feel free to upload a file over 5MB which cant be reduced in size through any of the various compression tools.

Also, keep in mind that I never said it would be a huge benefit at all- I only said that SOME compression was possible SOME of the time.

DanBlake··on “Should you encrypt or compress first?”
Im happy to reproduce in other formats. The contents are still random which is the crux of the issue here.
DanBlake··on “Should you encrypt or compress first?”
Using a random text generator http://pasted.co/encrypted.txt ( 10,002 bytes )

Then compressed it with winrar http://pasted.co/compressed.rar ( 7,743 bytes )

Roughly 20% compression isnt meaningless- so I fail to see why you are just giving a flat 'no' when its obvious what you are saying is untrue.

DanBlake··on “Should you encrypt or compress first?”
>Compression after encryption is useless, as there should be NO recognizable patterns to exploit after the encryption.

Not to nitpick, but this is incorrect. A encrypted file can very well have something like 100 X's in a row which the compression system could turn from XXXXXXXXXXXXXXXX.... into (100 x's go here) - Lousy example I know but it gets the point across.

Its also easy enough to test- Just encrypt a file then compress it. Sometimes it will be smaller. (Your reply indicated that in 100% of attempts compression is impossible)

DanBlake··on YouTube threatens legal action against video download service
the arguments against this are very similar to adblock legality issues.

Google wants to say "You can only view this content in a specific way" - Thats pretty much the same argument against ad blocking. The issue is if a ToS can force the issue.

DanBlake··on Massachusetts Right to Repair Initiative
I believe this is a big deal in regards to Tesla. Tesla locks down their cars to a insane degree- To a point where if you fuck around too much, apparently they call you up telling you to knock it off. With this law, I would imagine tesla would have little to no leverage with those folk

DanBlake··on Postmates launches Amazon Prime-style subscription service
Anyone have any math on how many orders / how much you would have to spend a month to make this worthwhile?
DanBlake··on Anatomy of a Co-Branded Credit Card
I have been contemplating creating a new credit card the last few years. Most likely under the Visa or Mastercard line.

The thought is, create a reward card specifically for high-value/vips that has the best rewards/cashback program on the market. Currently the best card is the SPG card from Amex which gives points that can be transferred to a plethora of partners and are among the most valuable points of all cards (around 2.9cents per point). What surprising is the cards currently for high-worth users have terrible rewards programs, ie the amex black card.

If you created a new card, the hope would be that you could offer more rewards to transfer partners by upselling 'these are vips' you should compete to get them.

The challenge is in figuring out how to make it all work. Credit cards make money 2 ways as far as I can tell- The 2.9% + 30cents on every transaction, as well as the interest paid on their bill.

So you should ideally have at least 3% of every transaction to give back to the user in rewards while living off of the 30 cents per transaction. Hopefully the interest paid on debts breaks even with the defaults.

DanBlake··on PriceZombie is shutting down
Im guessing the reason you were canned was less to do with historical pricing and entirely about the fact you let them compare with other sites.

I am fairly certain amazon hates that with a passion and is in fact why you dont see that feature on CCC.

Also, Its my understanding that all of these price comparison sites get a severely discounted affiliate rate from amazon- Something like 1%

DanBlake··on Privacy – Forget Your Credit Card
There is a few of these services and they all look awesome. The issue has always been for me that I value my points/miles more than I value the convenience of not worrying about my credit card # being stolen. If I could do this with my SPG card, I would be all over it.
DanBlake··on Justin Time
I dont see how it couldn't have. Twitch was almost undoubtedly built on the JTV tech stack and staff. Also consider that Amazon owns the justin.tv domain.

DanBlake··on Foreigners turn to India in search of cut-price, life-saving cures
Im curious what is stopping some other countries (even micro-nations) from instituting a policy that forfeits all patents on medication.

Lets say you take the country of Saint Lucia- Could they not spur the economy (among the lowest in the world by GDP) by saying any company can manufacture any existing drug and sell it? I feel like the medical tourism for that could be extreme, especially since there is still many treatments india still does respect the patent for.

If the country put it in their constitution that all drugs should be a human right, could a legal action be taken against the country itself? I imagine the only recourse would be the pharma companies trying to force legislation in other countries to bring sanctions, but I think that would be a hard sell.

DanBlake··on Acceptable Ads explained: monetization
The lack of a EULA does not mean you can do whatever you want. The DMCA still applies.

Also, many sites have a tos that governs what you can and cannot do. Regardless, its not illegal for you the user, but for ABP the company. They are profiting from circumventing software.
