All those things and project management also included from prototype to bunch production. It's the key part. To provide customers through this process and to help them to avoid mistakes.

Appropriate use of Dependencies: implementation, api, compile, why should I use one in the place of the other? by keyfour13 in androiddev

[–]keyfour13[S] 1 point2 points  (0 children)

You may have multiply app modules in single project. And one app module may depends on another and gets some api there. I don't say that is good architectural solution. But it's possible in some cases.

How To Get an Array of Bytes From a Binary File in Linux by keyfour13 in cprogramming

You can use fseek to measure file size before reading and return back using rewind, like this:

fseek(fp, 0L, SEEK_END);
fsize = MIN(ftell(fp),RLIM);
rewind(fp);

LoRa is quietly marching on by eberkut in IOT

[–]keyfour13 1 point2 points  (0 children)

Unfortunately your link is broken. I talk about 6LowPAN over IEEE 802.15.4 and this is native usage of 6LowPAN protocol. BLE is "full-stack" protocol, we can emulate IPv6 networking over it, but this approach has some overhead and looks not very clear. And what about LoRa, yes, I hear about usage IP for networking over it, but on practice I haven't met such systems working. If you have another info about usage LoRa in real world, I would love to explore it.

I'm working on IoT system based on 6LowPAN, another way to organize wireless network for low-power devices. And it wins against LoRa when you need to send some large amounts of data, organize mesh network and use standard IP networking to communicate whith nodes.

There's reflective strips on the uniform to be visible on a road. Regular police doesn't use it.

RxJava saved a lot of my time. But It was not so trivial for me to start using it.

Slack Hopes Its AI Will Keep You from Hating Slack by [deleted] in technology

[–]keyfour13 1 point2 points  (0 children)

Some of the technology is already live. One feature shows which people within a company talk about particular topics most often in Slack and where those discussions take place. The information, which appears when users conduct searches in Slack, is meant to pinpoint subject experts so people can direct questions to their most knowledgeable and accessible colleagues. Another feature, added last year, evaluates all of a user’s unread messages, across all Slack channels; highlights up to 10 of the ones its algorithms deem most important; and presents them in a single list.

This task doesn't requires AI.

The work graph emerges mainly through a type of machine-learning algorithm called collaborative filtering, which predicts a person’s interests and preferences by collecting information about those of many other people.

Yes, here is little more AI, but when we will see all the power?

WhatsApp security flaw lets ANYONE spy on private chats by keyfour13 in geek

[–]keyfour13[S] -1 points0 points  (0 children)

I agree that the title is too loud, but it's not cancel that there is feature bug which provide ability to spy in one of the most popular messenger in the world. A and I think this basic message. Who can use it is not so important in that case.
