Is it possible to extract entire blogspot blog?

Is it possible to save/export/download/print/whatever all posts, including comments, from a blog into .pdf files?

I don’t mean my blog, with access to dashboard, but any blog, the one I access as reader.

I’d like to preserve as .pdf and/or to print some blogs I have been reading for a long time; they all have thousands of posts, so opening and exporting posts one by one is not an option. Several of those blogs are at blogspot, and several on self-hosted WP.

Site scrapper such as HTTrack is halfway to what I want; it downloads everything in one go, but then I have to convert .htm files to .pdf and merge them. Is there a neater way I can transform a blog into nice e-book?

Thanks in advance.


android – React native keyboard’s height changes entire view

My layout with two inputs and a button works well without the keyboard. But as soon as I clicked the input box the keyboard appears and changes the height of the screen. Then things align wrong . I already tried using keyboard avoiding view. But the error is still there.

import {

linux – Search entire Ubuntu machine for a word using SSH

How can I search an entire Ubuntu machine for a particular word using SSH?

Note: I am using the Windows program PuTTY to run my SSH sessions, but once I’m connected I have an ordinary bash session.

Following this answer on UL.SE, I’m using this bash command:

find / -xdev -type f -print0 | xargs -0 grep -H "search for this text"

But this command returns output even when access is denied or when there are no matches, and since PuTTY limits viewable session history, I cannot see all of the results.

google sheets – How do I get a formula copied to all cells below it in the entire column and increment by x instead of manually dragging it down to eternity?

You can do that using the following arrayformula in cell E2:


enter image description here

How the formula works:

First of all you need to make sure you place it in the correct row. That is if your range starts at the second row (like E2-E) row you place it in the second row. As you notice in the given formula the column is A. That is to show you that the column makes no difference. It could be any column. It is the row that is important.

Then we fix the step which is one above the one we want. In this case in order to have 8 repetitions, we divide by 9.

Finally, we can control the starting number by adding a number in the last part of the formula.In this case we start from zero so we add nothing.
But in columns B and C we start from 1 and 2 so we use:

in column B


and in column C

postgresql – How to lock entire Postgres table but allow reads

Sorry for the newbie question, but what is the correct table level lock mode to allow reading from a table but not writing to it?

If that is not available then you could block reads and writes.

Here is the documentation page, I just don't understand what it says:

Thanks for the help.

bitcoind: the entire Bitcoin node running on Synology is not visible to the network

Last week I bought a Synology (918+) and started running a full Bitcoin node (

To verify if the network can find the Bitcoin node, I checked with my external ip. Unfortunately, my Bitcoin node is not accessible. I have forwarded ports 8333 – 8334 on my router. When checking if the port is open at, it gives as a reason & # 39; Connection refused & # 39 ;.

Another thing that confuses me is this: if I check the logs it gives me the following (snapshot):

What I understand is that height is the height of the block how can this be height=1744387 when are we around block height 630335? What am i missing here?

Please note that I am new to running a NAS and a full Bitcoin node so any help is appreciated.

Placing an assembly with respect to the entire grid

by $ x = (x_1, …, x_n) in mathbb {R} ^ n $, leave $ Q_x = (x_1, x_1 + 1) times … times (x_n, x_n + 1) $ – the open cube you have $ x $ in its "lower left" corner.

Leave $ K subset mathbb {R} ^ n $. We can choose $ v in mathbb {R} ^ n $ so that
For any $ m in mathbb {Z} ^ n $, either $ (K + v) cap Q_m ne varnothing $or $ (K + v) cap overline {Q_m} = varnothing $?

This means that I want to change $ K $ so there is no cube to cross $ K $ only at the limit (of the cube). If necessary, assume that $ K $ It is compact. I am pretty sure this should be a well known fact, if true. I don't know what the correct tags are for the question, please help me.

Here is an idea that I am struggling to implement. We need to find $ v = (v_1, .., v_n) in (0,1) ^ n $ so yes $ x = (x_1, .., x_n) in K $ and $ x_k + v_k in mathbb {Z} $so there is no open cube that prevents $ K $ and has $ x $ at its limit so let's consider points of $ K $ that are in the limits of such cubes. We will differentiate ourselves by the size of the face.

For example, for $ n = 2 $ to consider $ F_ {1,1} = {x in K, Q_x cap K = varnothing } $ – the dots in the lower left corner of a square that avoids, $ F_ {1, -1} = {x = (x, y) in K, Q _ {(x, y-1)} cap K = varnothing } $ – the dots in the upper left corner of a square that avoids, $ F -1.1 and $ F -1, -1 $ similarly defined. It is easy to see that these are not dense anywhere.

Also, define $ F_ {1,0} $ be the set of all $ x in mathbb {R} $ such that there is $ y, z in mathbb {R} $ such that $ (x, y) in K $, $ z <y <z + 1 $ and $ Q _ {(x, z)} cap K = varnothing $. This means that $ (x, y) in K $ it is inside the left side of a square that it avoids. $ F -1.0, $ F_ {0,1} $ and $ F_ {0, -1} $ they are defined in a similar way. The missing step: shows that the sets $ F_ {1,0} $, $ F -1.0, $ F_ {0,1} $ and $ F_ {0, -1} $ they are small (specifically – lean).

Now the quotient maps $ mathbb {R} a S ^ 1 $ and $ mathbb {R} ^ 2 to (S ^ 1) ^ 2 $ map meager sets to meager sets and (a meager subset of $ S ^ 1 $) times $ S ^ 1 $ is scarce in $ (S ^ 1) ^ 2 $. So, there is $ v = (u, w) in (0,1) ^ 2 $ such that $ x in F _ { pm1,0} Rightarrow x + u not in mathbb {Z} $, $ y in F_ {0, pm 1} Rightarrow y + w not in mathbb {Z} $ and $ (x, y) in F _ { pm1, pm1} Rightarrow (x + u, y + w) not in mathbb {Z} ^ 2 $.

The same idea "works" in the overall dimension module of the missing step (which is probably even more complicated).

apache: rinsed cache selector in Adobe Experience Manager without emptying the entire directory

How can I use selector-based cache flushing in Adobe Experience Manager?


Let's say we have xml cached under the folder like


I need to provide selector based caching, i.e. flush en.child1.xml alone and should not be rinsed en.child2.xml when the download request occurs for /content/myapp/us/en.child1.xml
I have tried invalidating the dispatcher download through an HTTP call like:

GET http://mydispatcher/dispatcher/invalidate.cache
CQ-Action Activate
CQ-Handle /content/myapp/us/en.child1.xml
Content-Type Application/xml

But, all the files under us folder (i.e. all selectors for en page) be invalidated. How can i invalidate just en.child1.xml?

linux – Eclipse is randomly delaying the entire Fedora 30 system

I have problems with my Eclipse 2020-03 (with the previous version it was the same), which I am running on fedora 30. At some random points, it seems that the whole system is overloaded. It turns out that the PC is working properly, I can perform all the actions, but they take 30 seconds each, and I want to see the result of saving by pressing Ctrl + s or switching between two windows (even while changing it (happens in slow motion). I know it's saved, and I even assume it's saved right away. It almost seems like there is a problem with just the graphics.
The problem occurs only while using eclipse, and not always (although 95% of the time after using eclipse for 2-15min). The closing eclipse doesn't solve it! It persists until restart. There are also times when everything starts working properly for a few seconds, but then it always comes back to delay. Today, for the first time, the system froze completely and I had to restart it by pressing a button instead of the console.

I increased the values ​​in eclipse.ini from -Xms and -Xmx and that helped a bit. Increased the time before the delay occurs.

I didn't find anything useful except that. It is very annoying and I can't encode anything while I'm on Linux because of that please help me. If I can provide additional information, please let me know.
