snadal··on Dawson – A Serverless Web Framework for Node.js on AWS
That is the point. It is a terrible idea to provide full administrative privileges to something you are testing. I.e, it does not need to remove EC2 instances so it is a bad idea granting it against you AWS account.

If the tutorial provides a policy ready to copy & paste with all the required privileges, you will be able to customise it better or just using it as it is.

Why so many of this frameworks insist in using an account with administrator privileges?

From the docs: "search for a Policy named 'AdministratorAccess', click next and confirm".

It would be much more convenient to request only the needed privileges while teaching the user what is the tool doing in the background.

snadal··on Ask HN: Why doesn't Adobe just kill the Flash Player?
We're here also maintaining some big platforms using Adobe Flash.

Even I mostly agree on the need to reduce unnecessary Flash usage on the public web, there are some features Flash provides that can not still be replaced by HTML5, like audio recording on browser which is not available on some still widely used web browsers.

If there is a need of providing support for those features on relatively old browsers in corporate environments then the best (the only?) choice is Flash Player.

I can also argue on the far less number of development and testing hours needed compared with HTML5 equivalent, where you know that content will render perfectly on all browsers that include Flash Player.

IMO, before killing player itself we will should focus in killing all those old browsers versions to provide developers a real alternative for these features.

snadal··on Google is not just a platform – It frames, shapes and distorts how we see
In fact, there are very few subjects where reality is a matter of fact and there is an absolute truth.

Even knowing this specific case is very clear to all of us, cherry picking which side is true and which one is false on ideological matters can be tricky. The line between truth and censorship is very thin.

Why don't just all of us learn to put everything in doubt? We've passed from "this is true because it's written on a book" to "this is truth because some jerk wrote it on Facebook"

This is an awful result, but it raises a difficult question: should the SERP be moderated or they should be fully automatic and allow this kind of results to be in the top of the result pages? Because a human moderated results could be even worst in the short them (who decides the ideology).

IMO, what must be addressed is our and our children ability to discern, analyse and put in doubt everything that we read, and this kind of results does more good than bad on this sense.

snadal··on Run Unix processes inside your browser
Disclaimer: not being sarcastic at all.

Can someone explain what can be the use case for this?

snadal··on Ask HN: What was your best passive income in 2016?
Some years ago, I did some referral promotion for a webhosting company with nice results, around 70k.

Later, company rules changed and I stopped actively promoting it, but second level referrals still are generating 5-10k year with doing absolutely nothing of work.

snadal··on Show HN: Time stamps for your phone or computer
Very nice :)

Thank you for sharing. I find it very useful in note taking or for work log diaries... I will use it :)

snadal··on Show HN: Get control of your Linux servers
Thank you for sharing.

Definitely I'll give it a try on some internal servers :)

snadal··on Show HN: Get control of your Linux servers
Really nice, indeed.

Very useful too the hints on each metric. I've not read docs in depth but I'd like to see also a compacted dashboard to avoid scroll for the latest ones.

Congrats :)

snadal··on TrueOS Pico – FreeBSD ARM/RPi Thin Clients
Can you point to any 10g switch on that price range? Last time I searched for there all were over $700 - $1000 USD.

Alternative was to use a 4 ports NIC with bonding but 10Gb will be far more easy and stable.

LTSP 4 uses XDMCP as Login manager and GUI export.

LTSP Clients boot with PXE and get the root filesystem via NFS, then it uses XDMCP login screen.

AFAIK, LTSP 5 uses LDM instead of XDCMP.

snadal··on TrueOS Pico – FreeBSD ARM/RPi Thin Clients
Our company has been running LSTP on commodity hardware since 2013 for a development team, and I am truly happy with the result.

For a long time, a 2013 i7 CPU with 32 GiB RAM running LTSP over ESXi was more than enough for intensive use of 5 thin clients.

We've recently switched to a more powerful server (refurbished 48 AMD cores / 256 GB RAM) running Proxmox and despite some issues that still needs minor tweaking, I am very happy with it.

The only gray area, and the reason I am always looking for alternatives to LTSP (NX2Go is the strongest candidate), is the huge bandwidth used by LTSP: 8 Thin clients needs a sustained 600 Mbps. I'm afraid scaling over 10 / 15 workstations will require expensive network equipment but graphic user experience is near native in all aspects.

I highly recommend to anyone that is in doubt of using LTSP or any other thin client setup in production, give it a try because it actually worth it in all aspects.

snadal··on Speech-to-Text-WaveNet: End-to-end sentence level English speech recognition
Hey, thank you for the link to you article. I've read it throughly and I cannot agree more. And that was written two years and a half ago, before the AI "explosion" that we saw later.

Actually, checking against confidence is something that we've tried to play with, but to my knowledge there is not a model that allows you to compare speech confidence against an specific text. Public APIs like MS ProjectOxford.ai can return a confidence, but against the "recognised" text, not against a predefined text.

Going further, this kind of approach can be very effective on words and small sentences, but I'd really love to see which specific phones the learner is failing, which can help in analysing full speaking exercises.

It works, but I am sure it should be possible to do better

snadal··on Ask HN: Remote workers, what headphone/mic combo do you use for video calls?
For intensive use I'd recommend against use of headsets.

We've found the Jabra Speak 410 (USB) and Jabra 510 (Bluetooth) speakerphones to be much more comfortable and microphone and noise cancelling are excellent.

IMO speakerphones are much more natural to use than headsets for a daily use.

snadal··on Ask HN: What would it take to convince a tech cofounder to join your startup?
Unless you have good funding or a customer with a pre-sales signed contract, I myself would be very reluctant to even think about it. If your idea is so good to worth it, just hire it.

Sorry but I've received too many promising proposals, and even in some cases, I was asked to sign an NDA that forbid to compete with the "idea" even without knowing what the project was about.

We've worked in the past with CMU Sphinx too, and it is absolutely amazing the advances in this area in the last months.

A little bit off-topic, but do you know any recent work or paper for speech recognition in language teaching area ? (I mean, analysing and rating accuracy of speaker, detect incorrect pronunciation of phones, and so on)
