Ask Slashdot: How To Build a Morse Code Audio Library For Machine Learning?

DF5JT You are way too late for the party (79 comments)

CW is dead, buddy.

Dead as in "There are few people left on the planet who actively work CW on a high proficiency level without using a keyboard and a screen reader".

Today you can see ham shacks without a CW keyer as a norm, and if you see a CW keyer, the owner only in rare cases can go beyond 20wpm without breaking a sweat, making lots of errors all along the way and getting frustrated at hearing others do perfect CW, albeit with a keyboard.

To give you a sense of scale: There are no more than roughly 4-500 hams worldwide, who can use an electronic keyer in such a way that they can hold a meaningful conversation on the air at more than 40wpm at an acceptable error rate and who at the same time can follow such a conversation with their ears easily.

I know quite a few members of that minority and they are all like dinosaurs about to die out. The future lies in predictive keying by a computer, high resolution SDRs for decoding and give it another 10 years even the most ardent pro-CW people will make way for other digital modes that can handle all the distinct advantages of CW operating (FullBK/QSK, pile ups and propagation resilience) just as good or better.

Speaking for myself, by now I am fed up with going on the air and either listen to either machine CW or inept operators who never were afforded the luxury of good tutoring and coaching to make their CW better, more precise and fluent.

So, let me rephrase my initial sentence: CW may not be dead, but the true CW operator is a dying species and I can't see any merits to your project when the future is machine-only anyway.

Seriously? Even back in the early 2000s this was not an acceptable resolution anymore. Today this is not more than laughable, except maybe for a smartwatch.

Ask Slashdot: Tools For Managing Multiple Serial Console Servers?

DF5JT It'all there! Why don't you use it? (104 comments)

Disclaimer: I work for these guys: http://www.ovirt.org/Features/DRBD

As somebody said before, this shop sounds like a fragile thing if some of those people leave. If customers depend on it, it might be advisable to switch to standardized tools for managing KVM environments. oVirt is the upstream project to Red Hat Enterprise Virtualization, i.e. those guys who really know KVM.


oVirt has pretty much everything he could ever dream of - and it is well documented, so any successor will immediately be able to handle the environment. Of course Open Source, it has a very active community with real experts:


Can't think of any reason no to use oVirt. It the exact feature set the OP is looking for, addressing his specific needs:

"Having a minimal CLI console available can make the product more attractive to users who use the command line and prefer to avoid using the GUI. It can also provide a simple and fast shell that requires no special client besides an ssh client, without having to connect to the actual VM. Serial console access can also be used for VM troubleshooting at the lower level."

Here you are:

Also, oVirt has a very active community:

Take a look, it's free...

Ask Slashdot: Are We Witnessing the Decline of Ubuntu?

DF5JT Re:Only time will tell... (631 comments)

Yes, but it is slow.

And if you ever tried upgrading Fedora from the command line, you know what for a mess it is.

I'm certain it isn't used successfully by YOU on more than a few servers if you say that...

We support thousands of systems, and know what the difference is :)

It's workable for most situations, but it's crappy technology compared to .deb/apt-get

Your thousands of servers sound like a way to boast your own ego, no more.

Thousands of server run by a pro do not run Fedora, they run either RHEL or CentOS, depending on how cheap you are.

And of course, for updates to thousands of systems a real admin knows how to use either Spacewalk or Red Hat Satellite, again depending on how cheap you are.

That said, yum update works fine on this machine.

What again was your point?

Middle-Click Paste? Not For Long

DF5JT Re:Who cares? (729 comments)

I have never fully switched to KDE4 because of many of its limitations, the most annoying being the network, memory and CPU load panel displays. In KDE3 one had the option of displaying absolute values in a pre-defined range. Gone in KDE4; all you can see are wobbly displays with relative values that have, err, relatively low value for their actual purpose.

These days I am really happy for the KDE3 fork http://www.trinitydesktop.org/ and ever since it works on Fedora 19 I can now go back to a functional desktop both at work and at home.

And, yes, the middle click works fine ;-)

When RedHat submits something, Canonical will point out any reasons it shouldn't be accepted.

I had a good laugh when I read this.

Red Hat employs hundreds of software engineers, contributing a lot to the entire Linux ecosystem. Canonical's resources in terms of code contribution are laughable in comparison and being a streamlined business Cacnonical has few, if any, resources to review third party code. They are happy to ride along, but the number of people at Canonical who actually write and read code outside the shiny UI field are hardly those with the expertise to review low level kernel code.

Red Hat CEO: Bring On the Clones

DF5JT Re:Pirating Windows? (182 comments)

That is actually incorrect. The CentOS part of your installation invalidates your support contract/subscription for the RHEL part of the cluster.

Red Hat does not offer you the option of a mixed anvironment. It's either all Red Hat, supported, or mixed and completely unsupported.

I am with Red Hat on this one, actually.

VMware CEO: OpenStack Is Not For the Enterprise

DF5JT Re:What to make of OpenStack? (114 comments)

Coupled with that comes my prediction that OpenStack will "fragment" rather sooner rather than later, with each of its backers offering some sort of "enhanced" ("enterprise") version (with stability patches and some additional features) that may or may not be a bit cheaper overall than VMware (all things taken into account), leaving you with a solution that works "almost like VMware, for almost the same price".

Am I too pessimistic?

I believe you are.

With Red Hat having jumped on board, Open Stack is going into a new direction that will not lead to fragmentation, but to consolidation. Red Hat's is one really good player in terms of Open Source. They throw resources at projects and they always do this upstream, delivering patches, enhancements, integration bits right where they belong and where they help the community best.

Red Hat is a guarantee that Open Stack will evolve into the next generation enterprise platform and VMware's CEO is either scared to death or simply a moron.

How the Internet Became a Closed Shop

<quote>Sad time? alt.tastless vs. rec.pets.cats? And when AOL users got on IRC... that was so much fun.</quote>

Oh, the memories.

Believe it or not, but we have just adopted two cats and named them "Sootikin" and "Choad" (I have vaccination documents to prove this). And just this summer I have had a great Steak in Cleveland with the Canadian guy who initiated the original war.

Yeah, most of you don't know what I am talking about, but a.t. in its original form was the best invention since the wheel was invented. I just wonder: Where do people openly talk about bodily fluids, politically incorrect rants these days?

For the past 3 months my internet has come from wireless LTE with 100MBit down, 10MBit up at consistent speeds that put my previous cable connection to shame.

All this in a European capital with dense population and one of the highest rates of smartphones per inhabitant in the world. All this at 49 EUR a month with no data limit. And no restriction whatsoever; no URLs blocked, no services disallowed, streaming via p2p, VPN and ssh tunnels.

The Coming Internet Video Crash

Austria has unlimited data plans.

I have a SIM card from drei.at that you can use without a contract and recharge on a monthly basis. It comes at 15 EUR a month and gives you high speed HSDPA+ without a cap. Also, my regular internet comes wireless these days: I have an LTE contract at 49 EUR a month that gives me unlimited 100MBit down and 10MBit up. I live in central Vienna and I actually get the advertised speeds.

There you go Sweden, plus we have better weather and better food (and we don't extradite ;-))

Ask Slashdot: Open Vs. Closed-Source For a Start-Up

DF5JT The business power of Know How (325 comments)

Since I work as sales director for an Open Source company, you will know my answer.

Tell your partner, that not only will you keep your technological advantage, but you will always be one step ahead of any competition if you work with a community. Be a leader for that community. Provide an infrastructure that makes communication easy among contributors. Inspire them by giving directions and accept input at the same time. Tell the community about your goals, let them be part of the story, inspire them to contribute and make yourself a desirable target for talent.

What you need is a clear focus on your business model. As an Open Source company you will market your know how, your unique expertise and tell everyone that you and only know are the ones to support a customers into the deepest abysses of technical problems. Find partners and share your expertise. Identify key contributors to the project and hire them. Be the experts in your field of knowledge and make yourself independent from a product that others can copy. Develop a business case, a sales pitch that potential customers will easily understand and identify as something that will bring a distinct advantage to their business by using your product.

One last thing: You will have lots more fun building an OSS company than going the closed way. You will be part of a community, you will lead it and you will continuously get input from intelligent people, input that otherwise will cost you dearly when hiring external consultants.

Finding Linux freaks for work in Europe

DF5JT DF5JT writes  |  more than 6 years ago

DF5JT writes "I am currently on a retainer from a large, multinational Telco Enterprise based in Germany that is 90% based on Open Source Software in its infrastructure. The company runs a number of data centers with more than 50.000 servers and is in desperate need for competent administrators, security engineers, network engineers, programmers and other tech related jobs.

The job market in Germany is full of people with Microsoft certificates, but those with Linux knowledge are impossible to find, since the demand is way higher than the supply. The company is willing to hire savvy people from overseas and sponsor the visa application, but finding these people is the problem. All the regular job pages do not offer me any competent geeks that are willing to relocate to Europe.

Question: How do I reach my target audience. i.e. Linux guys willing to go for an adventure in Europe, learn a new language, appreciate a new cultural experience and broaden their knowledge by working for a high tech company?"

DF5JT DF5JT writes  |  more than 7 years ago

DF5JT writes "Imagine: You have at your hand a fully equipped office, a staff of two telesales agents and 3 months to show that Linux in itself is a product that you can sell. Your goal is to penetrate SMBs that usually run Windows on all their servers and desktops and try to convince them that Linux is a veritable alternative, both from a technical and financial side.

How would you do it, who would you talk to and specifically, what would you try to sell them on the phone?

Would you mention Vista and its downsides? Would you mention terms like vendor-lock-in, proprietary standards and Trojan attacks? Or would you stick to Linux' advantages and emphasize Open Source as a development model, costs of licensing and Open Standards?

Tell me your view, because I'd like to learn about your experience, since I have now at my hand a fully equipped office, a staff of two telesales agents and 3 months to show that Linux in itself is a product that I can sell."
