FCC Prohibits Blocking of Personal Wi-Fi Hotspots

iamacat 802.11w (85 comments)

FCC will not stop a moron staying in one of hotel rooms (or say appartments) sending disconnect packets to everyone around them. The only solution is to secure your network from trivial sabotage and applicable standards are readily available. Why waste time policing the hotel itself when every one of it's guests can do the same thing and worse?

Ask Slashdot: GPU of Choice For OpenCL On Linux?

iamacat Try what you have first (106 comments)

Integrated graphics in your CPU will have a modest performance but stable and open source OpenCL driver. If it proves too slow for your particular project, you will be able to compare benchmarks and get the cheapest card that is fast enough to, say, run your animation at 60fps. If you are planning to distribute your code, you will anyway need several GPUs to test with.

Systemd's Lennart Poettering: 'We Do Listen To Users'

iamacat Nobody is forcing you to use systemd (551 comments)

However, you can not force other people to keep supporting your preferred alternative. Either contribute patches or pay RedHat or another commercial provider whatever is worth their time to maintain the alternatives for you. You want shell script-based init to tinker with your system, right? Well...

Steam For Linux Bug Wipes Out All of a User's Files

iamacat Sandbox (329 comments)

Android enhancements have been merged into Linux kernel, and it had solution to this problem for years. Time to support sandboxing in userland of mainstream Linux distributions. Then Steam can reset its own data all it wants, but can not harm the rest of the system. Nobody is taking away your freedom to give appropriate permissions to system administration tools, but you don't usually want games to administer your system.

Radio Shack Reported To Be Ready for Bankruptcy Filing

iamacat Central Computer (314 comments)

In Silicon valley, this is the store to visit if you miss the original spirit of Radio Shark or Fry's. I came to San Mateo when I was ready to make a new gaming rig. The last one I assembled ran Windows 95 and I had no idea about new standards or merits of different components. After many years getting my personal life and career in order I finally had a little time for hobbies once again. The lady who helped me was very knowledgeable of which components would help me stay within in a budget and what exactly will work with given games and operating systems. There was no hurry during the process that took nearly an hour, or aggressive upsell for things I didn't need. Any other big stores did not have this friendliness to hobbyists for ages, if ever.

The only thing is missing is a place that sells more basic components like capacitors and resistors and tables with soldering items and breadboards to assemble electronics. Something like "Color me mine", but for electronics rather than ceramics. At least one store would do great in Bay Area.

Study: Belief That Some Fields Require "Brilliance" May Keep Women Out

iamacat Don't know if title is troubling or insulting (218 comments)

Success in pretty much every field depends on brilliance, enthusiasm and perseverance in roughly equal measure. If you have 2 out of 3, you will probably earn a good living. It's unlikely that all 3 are significantly correlated with gender in any field, be it software development or early childhood education. If you live in United States and rule out a career path based on your gender, you likely have to do some work on yourself rather than blaming any external factors.

The Mainframe Is Dead! Long Live the Mainframe!

iamacat Re:I didn't think they called them that these days (164 comments)

Of course! A physical 5 processor machine running at 3Ghz would cost peanuts in hardware and power compared to an intentionally crippled 141 processor mainframe. What really happens is you pay (cost - subsidy) for the crippled machine and you or someone else eventually pays (cost + subsidy) for the less crippled machine.

With software, the equation is better. If someone sells you an edition limited to certain number of concurrent transactions, there are no manufacturing costs for your copy that have to be passed to someone else. Furthermore, you have a choice of free software and more basic software from company with smaller development costs. If done right, basic editions can also have lower memory and CPU requirements.

Unless you are saying that IBM is selling $1M systems that cost $50K to manufacture and their marginal costs are also negligible. In this case, you are better off going with a company with lower development costs that addresses just your use case specifically.

The Mainframe Is Dead! Long Live the Mainframe!

iamacat Re:I didn't think they called them that these days (164 comments)

To a finances guy, it means you pay for all your hardware and its power use, but have access only to a subset of it most of the time. Inactive hardware costs exactly same as active hardware to develop and manufacture. You are paying for a "discount" on spare capacity with jacked up prices for active capacity.

The Mainframe Is Dead! Long Live the Mainframe!

iamacat Re:Only for organizations that need a dozen of tho (164 comments)

You are going to serve your Chinese customers from US datacenters? Hehe. Connectivity between world regions is glitchy and high latency. Amazon, for example, provides 9 regions for its compute instances and they don't spend money for these datacenters just for the heck of it.

Even within a region, you are proposing paying for network and other equipment to handle 100% of peak traffic in each datacenter, while one sits idle most of the time. It would be much cheaper, and provide lower latency, to have 3 datacenters capable of handling 50% of peak traffic and all taking traffic at the same time. If one fails or suffers a network partition, the other two maintain a quorum and continue processing requests. In your scheme, a failover will lose at least some recent changes.

As for your "CBU engines", they are regular hardware crippled by DRM. You are paying for your "cheap" backup mainframe by jacked up prices on your primary mainframe. If both were the same, you would have access to more capacity for the same price.

The Mainframe Is Dead! Long Live the Mainframe!

iamacat Re:Only for organizations that need a dozen of tho (164 comments)

Hence the point that you should not buy those unless you can afford a dozen. If I only need the power of one of those, I would be better off purchasing less powerful/cheaper systems to distribute worldwide.

The Mainframe Is Dead! Long Live the Mainframe!

iamacat Only for organizations that need a dozen of those (164 comments)

No matter how reliable and maintainable the box itself is, I wouldn't want my business to lose days or weeks of revenue because the datacenter was swallowed by a sinkhole. Having hundreds of cloud compute instances around the world also helps compensate for network latencies and quickly cut expenses during a business downturn.

I am sure there is a scale at which it makes sense to have dozens of these boxes rather than many thousands of separate instances. Just not sure if volume is enough for IBM to recoup their 1B investment. Good luck!

SystemD Gains New Networking Features

iamacat It will all work out long term (552 comments)

systemd team has interesting ideas about new features and performance improvements that can be achieved with legacy-free and tightly integrated code base for standard UNIX daemons. Once the benefits are proven, it would be easy to pick and choose between simplicity/modularity and performance and some features can be ported to shell-based init. I don't see systemd developers forcing anyone to use the project.

Intuit Charges More For Previously Offered TurboTax Features, Users Livid

iamacat Re:Hiring a CPA is like buying money and time. (450 comments)

Yes, but it takes a week to find papers and reset passwords for direct import from bank/brokerage accounts. If you have a hardcopy of everything in one place, filing by yourself is dead simple too.

Is Kitkat Killing Lollipop Uptake?

iamacat Re:Maybe because 5.0.0 and 5.0.1 have serious bugs (437 comments)

You do realize you can download an image and upgrade now rather than waiting right? The first time you ever do it, you will need to backup and restore a device, but pretty simple otherwise.

US CTO Tries To Wean the White House Off Floppy Disks

iamacat Re:Well understood technologies ... (252 comments)

Uh.. no! There are no sane reasons for using 1.44MB storage medium. I would fully understand CD-RW, zip drives or sd cards for reasons you described. And if you don't want to depend on single vendor, Blackberry is not the best choice.

Indiana Court Rules Melted Down Hard Drive Not Destruction of Evidence

iamacat Re:Hello microwave (181 comments)

From what I understand, all it takes is one knock with a hammer to ensure platters are bent and can never be used again. And there is no known practical method to restore data after a single overwrite with 0s. Everything else is pure paranoia.

Indiana Court Rules Melted Down Hard Drive Not Destruction of Evidence

iamacat Re:How is this supposed to work...? (181 comments)

- person uses drive for copyright infringement, a civil offense
- a lawsuit is filed
- it's now a criminal offense to destroy evidence

For civil cases, police is not involved, but it's legal requirement for both parties to preserve evidence and testify truthfully. For criminal cases, you can lie/conceal all you want without additional penalty. But jury will consider how trustworthy you appear to be very heavily.

Bots Scanning GitHub To Steal Amazon EC2 Keys

iamacat Re:people mess up. Bank calls before approving $10 (119 comments)

He did exactly that and .gitignore was accidentally lost.

Service providers are responsible for 90% of work by designing solutions secure by default and in depth. It should take multiple explicit steps and dismissed warnings for an inexperienced developer to incur a catastrophic financial liability.

Why Aren't We Using SSH For Everything?

iamacat We ARE using ssh and https for everything (203 comments)

telnet and ftp practically died a while back, http is on the way out. In most corporate environments, other protocols such as X are local only and remote use is over ssh tunnels. IMAP/SMTP takes place over TLS when using decent providers. I guess there is a question of whether SSH and HTTPs should be merged. But a lot of work has been put in both and would be difficult to replicate and make as secure from the start. No hurry.

The only exceptions are organizations with lax security (like Sony apparently) and cases where security or integrity is completely not an issue. I guess if you broadcast a video as unencrypted UDP over a local network, that's fine.

LTE Hotspot as the only cellular service?

iamacat iamacat writes  |  about 3 months ago

iamacat (583406) writes "I am thinking of canceling my regular voice plan and using an LTE hotspot for all my voice and data needs. One big draw is ability to easily use multiple devices without expensive additional lines or constantly swapping SIMs. So I can have an ultra compact Android phone and an iPod touch and use one of them depending on which apps I fell like using. Or, if I anticipate needing more screen real estate, I can bring only a Nexus 7 or a laptop and still be able to make and receive VoIP calls. When I am home or at work, I would be within range of regular WiFi and not need to eat into the data plan or battery life of the hotspot.

Has anyone done something similar? Did the setup work well and which devices/VoIP services did you end up using? How about software for automatic WiFi handoffs between the hotspot and regular home/work networks?"

ExtJS is trying to back down on LGPL

iamacat iamacat writes  |  more than 6 years ago

iamacat (583406) writes "For years, ExtJS was dual licensed under commercial license and LGPL. Now they decided to switch to GPL or commercial in an attempt to cash in on their popularity by pushing LGPL users into their commercial license. This is their right as code's owners. The catch? Jack Slocum of ExtJS is now claiming that their product was never licensed under LGPL and is threatening to sue people who redistribute old versions as such. That despite the previous license stating "Ext is also licensed under the terms of the Open Source LGPL 3.0 license". The author of a related project, gwt-ext, speaks out."

Let's all mark the April 26 as a day to mourn passing of a great gentleman who lobbied so hard for our freedoms."
