What is the current Status of major proposed BTC upgrades like Taproot, MAST, Submarine Swaps?

I have read during the last year about some very interesting BIPs or initiatives. I am not asking for their explanations, just would be great if anyone would know about their simple status as of now, whether they are still considered to be implemented at some point (do you know when?), or whether they have been removed from consideration…




4) Submarine Swaps

5) Consumer Lightning-based applications (desktop+mobile by Jack Mallers)

6) Drivechain Sidechain, by Paul Sztorc

7) Lightning over NFC, by Igor Cota

I just dont know where to track those initiatives .


Mouse very slow on Ubuntu Studio 19.04 xfce like Atari neve rdid

Very new distro, works as a dream, but like a “not you” again, very new also since 12 years in linux audio production, the mouse runs slow or directly on the welcome screen or after some minutes.

While checking out every reachable post, trying scripts and other wonderful solutions, I ask myself and now the ubuntu-developers: is there any solution possible in creating a patch and putting it into the updates?

To me, involved in complicated studio, patching, composing and mixing processes, this slow-mouse issue seems to me so stupid, that I am not able to understand that this exists, but it does. I mean in Atari ’94 the mouse worked properly.

Why it bothers if someone can de-anonymize anonymous network (like Tor)?

So we all know that NSA has the ability to track down Tor, I2P and all those anonymous networks. I know it’s a piece of old news, but the question always shows up in my mind. Which is why bother it? I mean all your communication is encrypted through public key cryptography even through the simplest HTTPS connection, so apparently, they can’t see what you’re sending through the network. So unless you’re visiting know illegal website, they shouldn’t be able to track you down isn’t it.

Like if you’re talking with your friend through FB’s Messenger, let’s say. There’s so much traffic in and out through FB’s servers, how would they be possible to identify that this traffic is between you and server and then track you down to your location by the IP exploit from the connection (as it’s one of the few stuff that isn’t encrypted).

If that’s true, then why bother if NSA has the ability to de-anonymize Tor network. Or even simpler, why should you use Tor network there isn’t any difference between standard HTTPS anymore? Plus, they still can’t identify you out from that pool of connection through FB server and with a Tor it might even standout from theirs view.

Can a intelligent, legendary item use its own spell-like powers like a normal intelligent item can?

The Pathfinder Core book states that and intelligent item uses & maintains its powers… but the legendary items description states that the bearer is the one that uses it.

This seems like common sense to me since legendary items are more powerful than normal intelligent items, but some of my fellow players are stating that legendary items do not use their own spell casting powers. That seems rather silly to me unless this is something specific to the “spell casting” ability, but even then those legendary powers are just emulating the normal intelligent items abilities.

According to the rules on intelligent items:

Unlike most magic items, intelligent items can activate their own powers without waiting for a command word from their owner. Intelligent items act during their owner’s turn in the initiative order.


All powers function at the direction of the item, although intelligent items generally follow the wishes of their owner. Activating a power or concentrating on an active one is a standard action the item takes. The caster level for these effects is equal to the item’s caster level. Save DCs are based off the item’s highest mental ability score.

From the rules on legendary items:

Spellcasting: This item allows its bearer to cast a limited number of spells as spell-like abilities. This ability can be taken more than once. Each time it’s taken, the bonded creature gains 5 points to spend on selecting what spells the item can cast. A spell costs a number of points equal to its level (minimum 1). The bearer can then activate the item to use each spell-like ability once per day. By spending double the cost, the bearer can use each spell-like ability three times per day. All spells must come from the same class’s spell list. No spell can have a level higher than the bonded creature’s tier. The caster level for these spells is equal to double the bonded creature’s tier. The save DC for these spells is equal to 10 + the spell level + the bonded creature’s tier.

Why does it feel like web development is a hodgepodge of frameworks and plugins? Where do I even start?

sorry for the “click-baity” title.

I am currently a Junior back-end developer, I write Java and Scala and I love it.

I really want to get into web-development but it seems like every time I look up some guide on web development it is really just a guide for a specific Framework, I totally understand that the way the web has evolved over the years has forced developers into more efficient and dynamic ways of building web applications, but as a beginner it is really frustrating not even knowing where to start.

If I’m following a Flask guide it feels like I’m learning Flask, not web development, and if I was going to switch to Angular I could maybe use 1% of the Flask skills I acquired.

I don’t want to learn Bootstrap, Vue or Django.

I want to learn web development.

Sorry for this being more of a rant (which I’m hoping at least in part made sense) than an actual question but I’m hoping someone can help me see the light.

SELECT do MYSQL com uso de LIKE % com termos não sequencial

Fiz um campo de busca input[type='text'] e o botão <button>Localiza</button> que recebe o termo e envia para o SQL que busca em dois campos no MySQL mas se os termos não estão em sequência o MySQL retorna 0 registro, mas na sequência exibem todos.

$  v = 'abc do de'; $  sql = "SELECT `a`,`b` FROM `tbl` WHERE `c` LIKE %$  v% OR `d` LIKE %$  z% ORDER BY `a` DESC"; 

Se em c ou d houver ‘abc do de’ aí retorna resultado, mas se apenas ‘abc de’, não retorna, é possível aperfeiçoar essa query?

Gmail: Inbox behavior changed, would like to see unread inbox emails only (“label: inbox, label: unread”)

Up until two days ago, my “Inbox” in Gmail has only shown unread emails at the top, with the read ones being shown somewhere near the bottom.

For some reason this has changed. While my “Inbox” tab still shows “32” next to it, on the right hand side I can now see all emails, including unread ones. But I’d like for my inbox to only show those 32 unread ones:

enter image description here

Googling for this has led me to the following URL: http://osxdaily.com/2013/06/30/show-unread-messages-gmail/. They suggest the following filter:

label: inbox, label: unread

This shows exactly what I want, but I’d like for this to be the default view, and not have to apply a filter each time.

Any idea how I can switch back to the old view’
