Mozilla Teases First Browser Dedicated To Devs

kosmosik Mozilla is loosing it (132 comments)

Mozilla is loosing it. Fx gets more and more irrelevant between various UI changes and more bloat added. Usage is declining. And yet they try to reinvent themselves with such ideas. What for? Just make a decent browser and build developer tools into it like everybody else does. What is the point of such product? To have yet another browser/platform to build and test for?

Debian's Systemd Adoption Inspires Threat of Fork

kosmosik Re:An opportunity for Debian? (555 comments)

And exactly what aspect of control is taken from you by systemd?

No it isn't. Lots of commercial unix like operating systems had moved on to some form of init system not based on shell scripts f.e. Solaris, Mac OS X etc.

> It's main selling point appears to be boot-up speed

No it isn't.

> IMO the cost that we must all pay for that extra speed is just too high

And what is the cost exactly? What exactly do you have against systemd? Only thing you stated is that it is monolithic and non unix way. I don't rally care about it. What practical limitation does it cause? Only valid complains about systemd I've read so far is that is not standard as it is an implementation and in theory this shouldn't be done like that. And I agree but still it exist, it works and it is not going anywhere. The second complaint is that it uses binary log file. It does in fact but I also don't care about that. I can config it to forward to syslog so it is no problem. Actually by using such architecture it can start logging earlier than sysvinit system which is better. These two flaws do exist but they do not rule against systemd in general. It is still a step forward in right dimension.

Look at CoreOS and its components like fleet - this is what systemd was designed for and it is strictly server operating system.

Debian's Systemd Adoption Inspires Threat of Fork

kosmosik Re:Boot/init is a critical stage (555 comments)

> The init process is a critical stage: failure tends to leave you with no access to
> the system to diagnose the failure.

Nowdays not really a problem. If this is a desktop system then just hook up a LiveCD with your choosen distro or an USB stick and go on from the live system. With live system images you have all the tools you need and as far as the system's storageis not damaged you can do whatever you wish. As for servers - well remote lights out, management cards, flash addons, consoles etc. you can do whatever to rescue the system. Or if you cant afford it just use serial console to the bootloader and add a failsafe recovery system partition with an image containing all the needed tools and you are ready to go. Mind that these means were used like long time ago even before systemd happened. ;) If you are thinking about disaster then get ready for it when your systems work.

> Shell scripts and plaintext log files may be primitive, but they have the advantage of being easy
> to read with minimal access and not requiring complex stuff to run

Look above - complex stuff to run is not as complex as you see it. You can easly run even an graphical desktop system to recover your system even if you wish for doing so (most live cds do so). You just need to plan it ahead.

> mainly they just require that basic binaries be available in the path

Systemd does not depend on these tiny binaries. In my opinion it is an advantage. It still needs to get unit information from somewhere (like local filesystem or fleet).

> Until I've got at least a basic system up and running enough to log in and work

This is probably the old or wrong way of doing stuff. Just boot from something else and chroot to the system and then check the problem.

> text-based tools will probably run to decipher binary logfiles

You reall don't need to decipher anything as the log files are not ciphered. You just need to open them with specialised tool (avaiable on your rescue media from which you have booted). You don't quite get why people have problem with binary log files do you? The problem is not about tools for accessing them - the main problem is if they get corrupt they are much harder to recover than plain text files.

> and modify configurations

With systemd you do not need any special binary tool to modify configuration.

> The only change I'd make is to make systemd use syslogd like everything else

But it does.

> SysV init scripts may be clunky and primitive, but they've been around a long time.

So?

> People know how to manage them, and they've had the kinks worked out of them and

It does. But I get what you're getting at - writing a startup script yourself. So maybe try writing systemd unit for your need yourself and then compare it to sysv. IMVHO systemd units are easier (as more simple) to write than shell scipts for sysvinit. But YMMV.

Debian's Systemd Adoption Inspires Threat of Fork

kosmosik Re:An opportunity for Debian? (555 comments)

> if Debian were to reverse their earlier decision and go back to sysvinit (or at least make
> systemd optional), then I think we could see many sysadmins converting their RHEL
> systems to Debian jessie

You are joking, right? The reason people use RHEL not Debian is primary because tons of commercial software built on SAP, Oracle and similar are *supported* on RHEL. That has little to do with RHEL or Debian being technically superior from each other. After all Debian and RHEL are just Linux distributions not so much different from technical standpoint you have similar technical limitations using these as both use Linux as kernel. People use RHEL because they need to have support for the apps they are running. Not because it uses this init system or other - none of RHEL admins really care about it as long as it is supported by the business apps they need to operate.

And also I don't quite get the shitstorm going on about systemd. I think compared to sysvinit it is a great step forward. And I'm a professional sysadmin administering just few Linux systems - couple of RHEL boxes (Oracle related stuff), some CentOS (for Zimbra and MariaDB which we use internally) and CoreOS with Docker and all of systemd glory mostly for my own amusement at our own webapps. All of these are systemd powered right now and I don't see any problem with that. Just works as an OS.

Oh and on home laptop, home nettop and few raspis automating stuff I use Arch Linux with systemd of course.

The Future of Stamps

kosmosik Re:Give it another decade - the problem will solve (131 comments)

> You can fax legal documents (...) the state of Utah (...) New York allowed (...) Australia allows it [cnet.com], and anther New York [etc.]

But you are you aware that lots of other countries than USA or Austrialia exist and such even tend to have precedent or non-precedent legal systems? I know that general tendency is to go to electronic means where possible but I am quite sure that there still are and still be situations in which the new/current ways are not possible and you need to keep the old system running to support them. For example how do you deliver legal papers to inmates who cannot use email or Facebook?

> Requiring someone to buy a laser device to burn "stamps" onto envelopes and packages won't work.

This I fully agree. The idea is so stupid I don't even know how it got here to Slashdot.

The Future of Stamps

kosmosik Re:Give it another decade - the problem will solve (131 comments)

IDK how it is in the US but here in Poland the post is like an institution. Fe. if you have an invoice or legal paper you can send deliver it yourself, you can send it by private held company like TNT, UPS, whatever but only when you send it via Polish Post (national operator) it gets so called the power of postal stamp. Legally if you choose the right delivery type it is valid as delivery in court. Such postage is still deeply embodied in legal system and I think it has some merit. In Poland f.e. you could run a company and register its address for legal purposes as PO box in some large office complex where you just rented a PO box. In case of this special Polish Post delivery it is an obligation to the office complex administrator to deliver this postage physically as he gives the PO boxes to his clients he also has an obligation to deliver such postage.

I think Post Office isn't going anywhere and lots of people still send physical letters due to legal conditions and I don't think it is Polish only thing. Also people tend to send faxes. F.e. I was required to send signed legal papers via fax (snail mail would take longer but was also an option) when we was changing our DNS owner information due to company name change. This is silly but still it has some silly merit.

But as for the gadget in the article - laser postal stamps? It sounds quite cool but it makes no sense as in no real purpose. People who use snail mail en masse tend to have agreements with their posts to bulk send it with stamp or pre-printed stickers or pre-printed envelopes. In some countries to obtain a "stamp" to send an letter you just send an SMS to paid premium number and in reply you get a number which you just write on the envelope/card. In Poland you can get fancy stamps with your design on it etc.

(I've used to work at Polish Post IT department head office)

Google Adds USB Security Keys To 2-Factor Authentication Options

kosmosik How does it work? (121 comments)

Cant wait to get my hands on one of these. Unfortunately Amazon doesn't ship to Poland so I can't get it here. I have two concerns regarding this:

I understand this is an amateur class device. Better (or is it?) than Authenticator app as you need to gain the physical key since a phone app can be accessed remotely at least in theory but still not hard security as corporate smart cards, RSA tokens etc. Just hardware two form auth for the masses and I guess it is a good thing to have (or is it?). But as I see the form of distribution of this hardware is quite loose. If I order it via Amazon (if I could) it goes through amazon warehouses, shipping company etc. - could this device be tampered with in shipping? Shouldn't it have a safer distribution method like physical store so you can randomly pick one and it couldn't be identified to your identity?

How does it work? It states that it requires supported browser (Chrome 38) on any platform it runs but does it also work in Chromium (I am using Chromium)? Can it be used in other applications f.e. VPN client, SSH client? Does it use some open source library, tools? How it works as a device - I plug it in and it registers as standard USB class device - what class is it?

I've tried to google these concerns for few seconds but couldn't find good information so please anybody could clarify on this?

Facebook 'Safety Check' Lets Friends Know You're OK After a Major Disaster

kosmosik Re:Can't I just post a message on Facebook? (130 comments)

Facebook filters your wall posts so not everything you post gets to everybody's feed. They are afraid people using Facebook get too many meaningless information from other people like look I just watched this Youtube video and you should too. So they use algorithms that select data you post to other people. I guess they select it by number of likes, views etc. So given that they DO censor what you post they are afraid that they could censor also such important information regarding your safety. But they are not afraid about you - they are afraid about legal issues surrounding this. So they invented a way to control whether you are allowed or not to post such critical information. In my opinion this is just about covering their asses, not about your safety.

Facebook 'Safety Check' Lets Friends Know You're OK After a Major Disaster

kosmosik Re:Overly complicated (130 comments)

Because from Facebook's POV (huh) such status update is not related to major disaster. As I see it they are doing it to omit liability in case your status update in fact would be real in case of serious incident. Right now they are doing serious filtering of what gets into your feed since they are shit crazed about people leaving Facebook getting sick of all the irrelevant crap they see. This (proposed in the article) way they can select on the basis of fact of some disaster happening who can post such updates and these updates would be omitted by their what-is-interesting-and-what-is-not filters.

Apple Announces iPad Air 2, iPad mini 3, OS X Yosemite and More

kosmosik Re:Confucius say: (355 comments)

That is similar to what is going on with PC laptops. Basically MacBook Air is an ultrabook in PC nomenclature. PC ultrabooks also tend to be less upgradeable and serviceable than bigger laptops. For example compare Lenovo ThinkPad 430 and 430u (u - as in ultrabook). The slim design just forces use of smalled perhaps nonremovable parts. IMO all PC laptops that match MacBook Air size are also as unupgradeble and unserviceable as MacBook Air - it is not a marketing choice by Apple but the size imples it. Also what is new that you can't upgrade or service your phone or tablet - any brand. Get over it.

Apple Announces iPad Air 2, iPad mini 3, OS X Yosemite and More

kosmosik Re:Confucius say: (355 comments)

> For my 2006 Black MacBook, I maxed out...

The newest Mac OS X 2006 MacBook can run now is Lion (to be honest - you CAN run Mountain Lion but it involves hacking the install media, some voodoo with kexts etc. - I would not be sure about stability of such system). Which is now 3 releases old. Not a big deal if you really want to run it (simply put - you have no money for newer hardware) but it will certainly give you compability issues like recent versions of software not working at all. With PC laptops usually you can pop in recent-decent version of Windows even on much older hardware. It will run slowly (such as Lion on 2006 MacBook with 2Gs RAM) but it will run your software. With Mac you can't do that.

Experts Decry Randomized Ebola Treatment Trials As Unethical, Impractical

kosmosik Re:Our PC society will be our demise! (193 comments)

IMO you've mistaken political correctness and socialism terms for something else. Your first point about media censoring an opinion is in fact related to political correctness but after that you have no clue. Think about yourself - please answer this sincerely - if you or somebody close to you had contradicted Ebola abroad of your country would you wish your country to help you or not? After all you've had paid for your country's medical care in your taxes - and this is by no means socialism. So how would it be? Would you wish your country to help you or your close one or just leave you to certain death abroad perhaps in some uncivilized African country?

That is one great advance. DO NOT open equipment packaging in the data facility. Just do it somewhere else and bring it in unboxed. Uboxing in server room leads to loads of trash in the server room, dust and loads of other kind of garbage. Server room needs to be clean.

kosmosik Re:Wiring (52 comments)

I would rather put additional spare wires in connections between core units (racks?) just in case you need them. If one wire fails than switch to another one, mark that old one as failed and be over with it. You can trace it if you WANT to but you don't NEED to do that. It is good to have some spare backup wires.

kosmosik Re:Wiring (52 comments)

> My vote - one color - WHITE. Easy to label w/ a sharpie.

Why do you want to label wires with a sharpie? If you need to do so you are doing something wrong. Just use preprinted labels with numbers and barcodes (to easly scan these numbers). Attach label to each wire end and then input it into configuration database. In such database you can add all information you need - functional connection, physical connection (as which device goes where), even that floor positioning system - you have no limits. You just cannot and need not write all that information on the end of the wire - the end of the wire should be just unique id (human readable and scannable by device) and that is it. All the rest of data is in CMDB.

Why would you need to touch, trace and whatever the wires once mounted? Just put like 25% more spare wiring where needed (like between core racks) and if you have a wire failure just switch to spare wire and that is it. Wires are cheap, downtime and labour are not.

Ask Slashdot: Designing a Telecom Configuration Center?

kosmosik Some random thoughts (52 comments)

You are asking quite a broad question so I'll just throw in some random ideas since the topic is so broad you'll need to specify exactly what you have problems with and ask about it... and then iterate and ask again since it would be a long process.

1) Mount infrastructure systems like UPS and AC in advance and let them dry run so you can test if they behave properly f.e. ACs dont produce fog (I've dealt with such problem and it required changes from vendor) UPSs produce weird vibrations and so on. Just put the basic stuff to work as soon as possible so it you can overcome any gotchas it may cause.

2) Plan for expansion in advance - make proper room for additional AC and UPS units. Wire it accordingly. Put exhaust tunnels and everything needed just don't put the unit itself - this will make it much easier for you to expand if needed as you'll have all the work done already. Also add all racks you'll probably need later and wire them. Just don't use them - leave as spare. Racks and wires are cheap - labour is not cheap and it consumes time when needed.

3) Put additional canals (just empty space) below AC units as they can leak fluid.

4) Invest into cable management system so you can label each end of each cable with barcode and have a database of this configuration so you can scan every end of every cable and lookup what is its function where and to what it is connected etc. Don't bother with manually labeling each cable since it is tedious and probably will change in time. Just use generic barcodes attached to ends of wires. MAINTAIN this database as it is the most important stuff. Every single change must be noted in database. Peroid. No exeptions. Also don't bother with color coding the cables - usualy you will end with a mess unless you have a simple network.

5) Invest in security system like webcams on entry doors, RFID IDs and so on. It is not as expensive and will give you audited information on who, when had physical access to the facility. Be strict and anal implementing this - in case of non compilance f.e. somebody is trying to get unauthorized access just raise the alarm to local security staff. It is better to have false positives here.
