Misconfigured Open DNS Resolvers Key To Massive DDoS Attacks

mukund Re:Article is garbage (179 comments)

There is a rate limiting patch for BIND. The BIND package in RHEL/CentOS has it now:
https://bugzilla.redhat.com/show_bug.cgi?id=873624

A person has also attached a graph showing its effect on that bug page. I know of some other places which are using this patch.

(Disclaimer: I work for the organization that produces BIND.)

Could Electron Counts Detect Major Earthquakes?

mukund Re:Earthquake Shelter? (106 comments)

Evacuate cities?

People need to get out of buildings and away from things that can fall on them when there's a major earthquake.

Here most people die when they're crushed under concrete and other building materials (stone, bricks, etc.) in poorly constructed homes.

Something that says an earthquake is imminent would definitely help.

On the topic of computer power consumption ...

mukund Re:Computer is cheap (219 comments)

Running a couple desktops and laptops 24/7 results in a cost of about $10/mo, and that is if they are at full use. My desktop averages about 60w, and I haven't been able to get it over 150w. Quad core intel with 8G RAM and like 6 hard disks. I feel silly for buying a 600w power supply now.

Would you tell us what hardware you use for the CPU, RAM (how many sticks), disks, and power supply?

60W for all that seems incredible!

Sixteen Years Later: GNU Still Needs An Extension Language

mukund Re:People hate paren languanges (425 comments)

I once tried to use guile in the Gimp to do a few simple filters. Between the abysmal documentation and the clumsy syntax, I gave up in disgust after a couple of hours, and installed the Python Image Library instead. My sanity was saved.

GIMP doesn't use Guile. It currently uses an embedded fork of Tinyscheme, which is somewhere between R4RS and R5RS compliant, and somewhat not.

Some people like Scheme (it is well suited to represent order of graphics operations), and some hate it. That's why GIMP supports Python and C too for extending.

I guess that sums up what other apps can do. You don't have to stick with "an" extension language when you can support many.

CS Prof Decries America's 'Internal Brain Drain'

mukund Why don't you get a job? (791 comments)

It's not all about top-notch brains. It's also about many not-so-clever brains at lesser salary. This was the reason why US companies hired foreign labor, and this is the reason why thanks to the H1B caps, companies are happy to go east to other countries.

Most CEOs (especially American CEOs) don't care about how well it will be for the company 10 years down the line. They care about the next quarter.

More and more jobs are global now in computer science. If there is a programming job, it can be had anywhere in this world, not just in America.

Plus, isn't America so well off thanks to migrants? Who invented your rockets and your bombs near in the past as 50 years ago? Who makes your microprocessors? Suddenly, you want to stop immigration and be protectionist?

This professor needs to stop dining and think a little.

OTOH, there's the big problem of Indian companies gobbling up H1B slots like it was property.. but that's a different problem. There's also the problem of poor quality labour --- programmers who can't code, thanks to sneaky HRs and those who undercut salary, fire the good programmers and hire the cheap ones. It looks good this quarter, but they'll soon find out. Again, this has nothing to do with migration.

Here, we have Biotech, Commerce students recruited into the CS industry. "Don't worry we'll train you in 4 weeks."

Why? Because we can sell this to the western company whose CEO is more than eager to pick up this plate because it's cheaper.

Imagine if a CS worker were hired in an airline as a pilot (Don't worry we'll train you in 4 weeks), or *shudder* as a surgeon. Quality programming is harder and needs more experience than all this.

In the end, the Indian programmers who actually studied CS and are good at what they do get a bad name on Slashdot and elsewhere, cause they're a part of the lot.

Hosting Giants Teaming Against Small Businesses

mukund Re:Switched to Hetzner.de, never looked back (163 comments)

Hetzner is OK, no comment here, but you do have to mention the downsides, such as absolutely no erotic content allowed (nudity, art, regular porn - have one person post a NSFW picture on your forum and you may get terminated) and relatively poor speed to some parts of US (I've seen average of 400 KB/s to Texas)

I did not know that. We run a company website, so this should not be a problem. However, we do run public forums. I wonder how _anyone_ can enforce any rules about posting in a forum. Even if you were to delete offending posts, there is still the time between when it was posted and when it was deleted. If they are policing, I hope they do it with a large grain of salt. This restriction about ordinary porn is very weird though. Is there something in German laws which disallows it?

mukund Re:Switched to Hetzner.de, never looked back (163 comments)

Not sure. I live in India, so most of the internet has worse latency than that. Germany is closer as long as we don't get routed through Singapore and the Pacific, kinda like touching your nose around your head. :) However, 120ms is not something I'd call bad for ordinary use. We use interactive SSH shells from here, and it feels good. If you are running something time sensitive like stock trading, maybe then you'd need something closer.

Hosting Giants Teaming Against Small Businesses

mukund Re:Hetzner.de (163 comments)

Apologies for the delay in replying.

Where are the servers located? Their own in Germany? Or reselling US-based?

They run their own datacenters in Germany. Check their website for details.

Also, does Banu or Mukund require enough resources to warrant your own server, as opposed to shared hosting?

Banu is a company. We serve the main HTTPS website, DNS, email, XMPP chat, mailman lists, bugzilla, git repositories, rsync for /pub, run virtual machines for builds, run other bits like IRC bots, bittorrent tracker + seed for large files, shells for people, etc. We are also working on a shop section.

Granted some of these can be done using free services on the net, but:

1. We lose identity by distributing things all around the net instead of handling our own infrastructure.

2. There would be a lack of absolute privacy for emails, private repositories, customer data, etc. This is very relevant now that we are launching a shop website.

3. Free services on the net tend to go away without a prior notice period to transition things.

4. The shared hosting scenario is not much different given the services that we run. It would need a beefy shared setup, and there'd always be restrictions compared to running your own server.

What we have now is well worth the money.

mukund Switched to Hetzner.de, never looked back (163 comments)

I used to host with ThePlanet for my websites. Though their services were pretty stable, they charge so much that I looked for other vendors after a couple of years. Switched this year to Hetzner.de. They provide a dedicated server for 49 EUR that gives me i7-920 quad core, 8 GB of RAM, 2 * 750 GB of disk space and 5 TB of bandwidth per month. Plus they have a great web-based system for remote rescue, reboots, and all services that run on the machine are now available on native IPv6. I haven't had any hiccups so far, and it seems well worth the money.

Their support staff seem to struggle a little bit with English, but their web-based rescue interface leaves little to ask the service staff about.

Leaked Letter — BSA Pressures Europe To Kill Open Standards

mukund Re:Some open standards lobbying in EU isn't credib (156 comments)

Oracle dismissing LibreOffice folks is pretty much what anyone else would do in their shoes. Let's say you have a project X. Some people with relatively less power in your project fork it to project Y, and say they do it because project X sucks. What would you do? Still keep them in project X? Replace X with an organization you head, and this will make more sense. This is the definition of conflict of interest, and the outcome is exactly what happens in such a case.

Ask.com To Shut Down Bloglines

mukund Re:Its not a suprise for its users (111 comments)

I had the same story, until Google started asking for my mobile phone number as verification to link to my Google account. IMO, this is over the edge, as in this country you have to use your real identity to get a mobile number.

Then, I switched to a self-hosted Tiny Tiny RSS and never looked back. I don't use Google accounts anymore, and don't have cookies or javascript enabled for any of Google's websites.

Except search and maps, I self host everything (email, websites, Jabber, RSS reader, calendar, etc.) on a dedicated server. There's a small price to pay, but as an example, I have the same email address for the last 10 years. I have all my emails for the last 10 years. There's no worry about privacy. As a programmer, it's useful to run irssi from it under screen, host my own websites, pretty much run anything network oriented..

Google Street View Wi-Fi Data Includes Passwords, Email Content

mukund Re:Ho ho ho... Felony. (292 comments)

The law doesn't care.

Stop thinking about your Wifi device. You emit a lot of information without knowing about it anyway. Read about TEMPEST.

Some people even believe that just cause they have swapped CRTs with LCDs, they are not vulnerable. They are usually wrong.

There are way many things that are private to you, but that anyone can collect on a mass scale and raise hairs. Like the time period during which your home's lights are on, and when they are off, the contents of your trash, what type of car you use, what colors/types of clothes you wear, etc. just by noticing you in public. Not all such information may be useful or cost-worthy to use today, but it's all information that says something about you.

Google Releases Wi-Fi Sniffing Audit

mukund Re:don't broadcast that stuff (198 comments)

Being willfully ignorant is hardly a compelling argument. Either your relatives are terminally stupid, deliberately unwilling to learn or you aren't very effective at teaching them what they need to know to keep themselves safe and secure. I don't buy this kind of argument at all. People aren't that stupid and they understand things of similar complexity in other contexts just fine. Stop making excuses for laziness.

These arguments on technicality are sidestepping the point.

Use of encryption has no bearing on whether listening in is legal or not.

Encryption is tough to get right in practice. It is tough for someone to learn all the nuances behind encryption. You can believe you have mastered it in a public multi-implementation environment, and have some sort of consolation that your data is safe, or was safely transmitted. But there are no guarantees. Algorithms, software and the general implementation may be weak. I provided the example of a rogue CA in an earlier comment. Encryption is a measure that _you_ and your recipient take to protect your data. It doesn't give anyone the right to snoop.

We don't know if Google snooped, or intended to snoop. It's for the courts to decide.
