Believe it or not, the hot temperatures (up to 114 degrees Fahrenheit) in the summer are just one of the many harsh conditions for the animals that live here. Animal adaptations are also aimed at coping with the dryness, lack of food, and extreme temperature changes. Every animal needs water to live. In the desert, water isn’t always there when you need it. Humans have a great advantage because we can plan ahead, fill up our water bottles, and carry as much water as needed (in the summer, about four quarts per person per day). Animals have to find water nearby on a regular basis, unless they can fly or walk a long way.

Module: ActiveRecord::Locking::Pessimistic
| Relationships & Source Files | |
| Extension / Inclusion / Inheritance Descendants | |
|
Included In:
| |
| Defined in: | activerecord/lib/active_record/locking/pessimistic.rb |
Overview
Pessimistic Locking
Pessimistic
provides support for row-level locking using SELECT … FOR UPDATE and other lock types.
Chain ActiveRecord::Base#find
to QueryMethods#lock to obtain an exclusive lock on the selected rows:
# select * from accounts where id=1 for update
Account.lock.find(1)
Call lock('some locking clause')
to use a database-specific locking clause of your own such as ‘LOCK IN SHARE MODE’ or ‘FOR UPDATE NOWAIT’. Example:
Account.transaction do
# select * from accounts where name = 'shugo' limit 1 for update nowait
shugo = Account.lock("FOR UPDATE NOWAIT").find_by(name: "shugo")
yuko = Account.lock("FOR UPDATE NOWAIT").find_by(name: "yuko")
shugo.balance -= 100
shugo.save!
yuko.balance += 100
yuko.save!
end
You can also use ActiveRecord::Base#lock!
method to lock one record by id. This may be better if you don’t need to lock every row. Example:
Account.transaction do
# select * from accounts where ...
accounts = Account.where(...)
account1 = accounts.detect { |account| ... }
account2 = accounts.detect { |account| ... }
# select * from accounts where id=? for update
account1.lock!
account2.lock!
account1.balance -= 100
account1.save!
account2.balance += 100
account2.save!
end
You can start a transaction and acquire the lock in one go by calling #with_lock with a block. The block is called from within a transaction, the object is already locked. Example:
account = Account.first
account.with_lock do
# This block is called within a transaction,
# account is already locked.
account.balance -= 100
account.save!
end
Database-specific information on row locking:
Instance Method Summary
-
#lock!(lock = true)
Obtain a row lock on this record.
-
#with_lock(*args)
Wraps the passed block in a transaction, reloading the object with a lock before yielding.
Instance Method Details
#lock!(lock = true)
Obtain a row lock on this record. Reloads the record to obtain the requested lock. Pass an SQL locking clause to append the end of the SELECT statement or pass true for “FOR UPDATE” (the default, an exclusive row lock). Returns the locked record.
# File 'activerecord/lib/active_record/locking/pessimistic.rb', line 69
def lock!(lock = true) if persisted? if has_changes_to_save? raise(<<-MSG.squish) Locking a record with unpersisted changes is not supported. Use `save` to persist the changes, or `reload` to discard them explicitly. Changed attributes: #{changed.map(&:inspect).join(', ')}. MSG end reload(lock: lock) end self end
#with_lock(*args)
Wraps the passed block in a transaction, reloading the object with a lock before yielding. You can pass the SQL locking clause as an optional argument (see #lock!).
You can also pass options like requires_new:
, isolation:
, and joinable:
to the wrapping transaction (see ConnectionAdapters::DatabaseStatements#transaction).
# File 'activerecord/lib/active_record/locking/pessimistic.rb', line 92
def with_lock(*args) transaction_opts = args. lock = args.present? ? args.first : true transaction(**transaction_opts) do lock!(lock) yield end end

And the Lord said unto Moses, Wherefore criest thou unto me?... Lift thou up thy rod, and stretch out thine hand over the sea, and divide it: and the children of Israel shall go on dry ground through the midst of the sea.
Exodus 14:15-16
If you hang around God very much, it won't be long before you'll start wanting to do things the world considers supernatural. You'll start wanting to lay hands on the sick and have them recover. You'll start wanting to cast out demons. You'll start wanting to cast mountainous problems into the sea. What's more, you can do it if you want to!
How? Not by jumping out and "trying" to do supernatural things, but by obeying God one step at a time. By doing the things He's already given you power to do.
That's how it happened with Moses. He didn't have the power to divide the Red Sea. But he did have the power to stretch his rod out over it. And when he did that in obedience to the Lord's command, the Holy Spirit did the rest.
It will be the same way with you. When you start doing your part, the Holy Spirit will do His and supernatural things will start happening around you. What is your part? Feeding on the Word. Praying in the Spirit. Listening to what the Spirit of God says to you. As you do those things, as you move as God impresses you to move and take your direction from Him, you'll flow in the supernatural as naturally as a bird flies in the air.
You won't struggle and strain and try to "part the sea." You'll just trust the Lord, stretch out your rod... and watch the miracles roll.
Scripture Reading: Exodus 14

From 5.31 we want \(x>y\) but
\[\log \frac{x}{1-x} +\log \frac{a_x}{b_x}< \log \frac{y}{1-y}+ \log \frac{a_y}{b_y} \]
i.e.
\[\log \frac{x}{1-x} - \log \frac{y}{1-y} <\log \frac{a_y}{b_y} -\log \frac{a_x}{b_x} \]
or, multiplicatively
\[\frac{x(1-y)}{y(1-x)}< \frac{a_y b_x}{a_x b_y}.\]
This is of course very possible. It means simply that the level of trust of N is sufficiently different between X and Y that the the difference of evidence perceived by X and Y from the announcement is bigger than their prior difference of evidences.
Everything in this exercise is conditional on \(I\).
If the “graphical model” assumption \(C\to B\to A\), is true (meaning that \(A\) and \(C\) are independent conditional on \(B\)), then 5.43 becomes
\[P(A|CI)=qP(A|BI)+(1-q)P(A|\overline{B}I)\]
and since \(P(A|\overline{B}I)\) is bounded by \(1\), as \(q\to 1\) we do have \(P(A|CI) \to P(A|BI).\)
In general, however, even \(q=1\) does not imply closeness of \(P(A|BI)\) and \(P(A|CI)\). Suppose we have a fair 4 sided die. Let \(C\) be the event “\(4\) is rolled”, \(B\) the event “the result is even”, \(A\) the event “the result is 1 or 2”. Then \(q=P(B|C)=1\), but \(P(A|C)=0\) while \(P(A|B)=1/2\).
By taking more-sided dice we can even make \(P(A|B)\) arbitrarily small while keeping the other implications.
An example “from life”: \(B=\)“I’m in San Francisco” implies that the probability that \(A=\)“It is snowing around me” conditional on \(B\) is very low. However, if I know \(C=\)“I’m in San Francisco and the date is February 5, 1976” then I am certain of \(B|C\) (so \(q=1\)), but also certain of \(A|C\).

Property Based Testing in Elixir
Basic of property based testing and how to do it in Elixir by StreamData
Brief: This is a story about a rookie alchemist to learn property testing in Elixir. If you are also a alchemist and want to know what’s property testing, welcome to share my experience. If you are not, in the first half of this story, there are some basic knowledges about property testing for your.
Maybe we should consider about property based testing.
In a retrospective meeting, a colleagues said this. So the story began…I knew nothing about it at that time.
What’s
property based testing
?
First of all I need more information about it. Is it a cool stuff? Or just another buzzword?
This is my first impression after gathering information: it’s a kind of random generative testing. It confuse me, what’s the difference with what we already have?
Try to get a deeper understanding, there is a new term appear: shrink
. It means that property based testing
can tell us what’s the minimal case to reproduce the error. Magic! Is there a rubber duck inside it?
Maybe I know why I should use
property based testing
.
Sounds great. Before that, we need to write so many test cases, and consider about corner cases. Now what we need is write a property test, and rubber duck will do all things for us the test framework can generate many cases including corner cases for us. If there is anythink wrong, it will tell us what’s the minimal case to reproduce error.
Recently I implemented a simple queue by Elixir. I think it should be a good sample to test by property.
Heaven is near…?
Everything is perfect. What I need in the future is 5~10 line of codes of testing, and ruber duck will save the world property testing will be responsible for everything else.
But, you know, as an engineer, it’s too smooth to believe. In order not to be as a fool, I add a test for 87 and it should be failed…because I am not an 87.

I repeated the test over 10 times and it always passed. I finally got the test failure after I restrict the integer range to 86~88.
So…is property testing useful?
Now we know that property testing is a kind of random generative testing with shrinking ability. It generates many random test cases including common edge cases such as nil value, empty list and so on. If it find anything wrong during the testing, it will try to shrink the erros, to find the minimal set which cause the problem. The property testing can test more and more different cases over time, maybe it could find something unexpected. But, if we already know you edge case, and the case is not common one (ex. the case of 87), we should add unit test for that case along with property testing. Then, the world will be beautiful.
How to do porperty testing?
- We need a property testing framework. In Elixir, we have StreamData.
- Suitable scenario. Key idea is about
property
orbehavior
. If there are some functions with specific property, it’s time to useproperty based testing
. - Using patterns.
In Elixir, it’s quite simple and easy to understand how to write a basic property testing like the example below.
property "for what purpose" do
check all item <- term() do
# test here by the `item` taken from generator
# ...
assert actual == expected
end
end
First line property
means we want to use property testing (its test
in unit testing). Focus on the second line. The term()
is a generator provided by property testing framework (here is StreamData
). StreamData provides many different kinds of generators, and term()
generate all types of data. If the parameter of our method only accepts integer, we can use integer()
instead here.
We can regard check all
as a for loop
. Literally what it does is like for all items from the generator
. The we can test our logic by the item taken from the generator.
What’s patterns about property testing?
There are many articles about patterns. Here I only list the most commonly used in my opinion.
Round-tripping
a.k.a. Encoder/Decoder. For example, we have
float to string
andfloat from string
two methods. We can generate random floating numbers, convert them to string then convert back, it should keep the same one.assert term |> encoder() |> decoder() == term
Oracle model
Here is not that Oracle. It means the older and correctness model we already have. For some reason such as performance we need to implement a new one. They should have the same
properties
.expected = oracle_code(term) actual = my_code(term) assert expected == actual
Smoke testing
a.k.a Build verification testing. To ensure the functionality of our method working. For example, our method should always return
{:ok, result}
and{:error, reason}
, then we can have a property testing like this:{status, _result} = my_code(term) assert status in [:ok, :error]
If it passed, it means our method works (no smoke or on-fired).
Stateful testing
If we have some stateful functions in our system, such as
Memcached
,Redis
,ets
orGenServer
in Elixir. We can use property testing on it like below example:

The most natural way to name locations in pic is relative to objects. In order to do this, you have to be able to name objects. The pic language has rich facilities for this that try to emulate the syntax of English.
The simplest (and generally the most useful) way to name an object is with a last clause. It needs to be followed by an object type name; box, circle, ellipse, line, arrow, spline, "", or [] (the last type refers to a composite object which we’ll discuss later). So, for example, the last circle clause in the program attached to Figure 9.1.3 refers to the last circle drawn.
More generally, objects of a given type are implicitly numbered (starting from 1). You can refer to (say) the third ellipse in the current picture with 3rd ellipse, or to the first box as 1st box, or to the fifth text string (which isn’t an attribute to another object) as 5th "".
Objects are also numbered backwards by type from the last one. You can say 2nd last box to get the second-to-last box, or 3rd last ellipse to get the third-to-last ellipse.
In places where nth is allowed, ‘expr’th is also allowed. Note that ’th is a single token: no space is allowed between the ’ and the th. For example,
for
i = 1 to 4 do {
line from ‘i’th box.nw to ‘i+1’th
box.se
}
You can also specify an object by referring to a label. A label is a word (which must begin with a capital letter) followed by a colon; you declare it by placing it immediately before the object drawing command. For example, the program
.PS
A: box "first" "object"
move;
B: ellipse "second" "object"
move;
arrow right at A .r;
.PE
declares labels A and B for its first and second objects. Here’s what that looks like:
Figure 9-1: Example of label use
The at statement in the fourth line uses the label A (the behavior of at is explained in the next section). We’ll see later on that labels are most useful for referring to block composite objects.
Labels are not constants but variables (you can view colon as a sort of assignment). You can say something like A: A + (1,0); and the effect is to reassign the label A to designate a position one inch to the right of its old value.

Xiaomi Redmi Note 8 Pro could get Android 10 by end of November 2019
The Redmi Note 8 Pro has recently been spotted on Geekbench, and it seems that it is running on a Google’s Android operating system. Based on a statement by gsmarena.com, we can expect the Android 10 update to be available on the aforementioned smartphone as well as the non-Pro variant by the end of November 2019.
However, do take note that there was no mention of whether it will be available globally or in selected countries. Do the information regarding the release date with a grain of salt, due to the fact that Xiaomi has not commented on it for now. Would you be upgrading your Redmi Note 8 series to Android 10 as soon as it is available? Let us know on our Facebook page, and for more updates like this stay tuned to TechNave.com.


Started in 2007, openp2pdesign.org documents research on open, collaborative, and co-design projects and the systems that enable them. A personal website of Massimo Menichinelli , Doctor of Arts in New Media & Master of Science in Industrial Design, contains his research and publications (including several books) on Open Design, FabLab and User-driven Open and Social Innovation initiatives.
The starting point for this research was Open P2P Design , a set of design guidelines and concepts for supporting communities in developing open and peer-to-peer collaborative activities. Its evolution, OpenMetaDesign is a framework for the meta-design of open, collaborative and distributed processes.

machine% ls -l ~plewis/2021/ETM-*The command 'ls -l' provides a 'long' listing of whatever you specify afterwards. In this case, '~plewis' refers to 'the home of plewis' (here otherwise known as /home/plewis). 2021 is a subdirectory of my plewis' home directory, and there are a bunch of files that start 'ETM-' - the * is a wildcard (meaning ETM_ followed by anything).
machine% cd DATA
machine% cd ~/DATA
machine% mkdir practical1change directory again (relative to where you are ...)
machine% cd practical1copy a file into the current directory ('.' == 'dot' == current directory)
machine% cp ~plewis/2021/ETM-* .Note that the * symbol is a wildcard, so '~plewis/2021/ETM-*' is all files that start with ~plewis/2021/ETM-. The . ('dot') means the current directory. ~ ('tilde' or 'twiddle') refers to the home directory of a user, so ~plewis refers to the home directory of plewis.
machine% ls -l ~/DATA/practical1
tells us that the disk known as /data/prague has 5873616
Kbytes available, for instance. Again, . ('dot') refers to the current
directory/filesystem.
Type:
machine% ls -l
which gives (among other things)
-rw-r--r-- 1 plewis ps 24094770 Sep 23 13:38 ETM-190600.gz
The compressed file (with a .Z or .gz extension) is 24094770 bytes (the original was 34200000, so the compression ratio is around 1.4 in this case).
or to uncompress:
machine% gunzip
ETM-190600
You also learnt
what ~, & and . mean.
Thats enough UNIX for one day! If you want to learn more UNIX or just
