] | **Чересчур** is one of those words that don't *sound* bookish, and yet you're radically less likely to hear it in everyday speech compared to **слишком**. **Чересчур** just isn't the word you'd immediately think of when seeking to express the idea of excess. But when you do hear it, it sounds perfectly natural and plain, "oh yeah, that's a word too."
Also I feel subjectively that **слишком** is more, as it were, focused. All other things being equal (i.e. discounting the abovementioned general likelihood to think of **слишком** as a word choice before you think of **чересчур**), you're more likely to pick **слишком** over **чересчур** if you think you can more or less point to the exact measure, or the exact cause, of the perceived excess. **Чересчур** is more of a "dunno, there's just too much of this here thing."
That said, **это уже слишком** "now that's enough!" makes you sound annoyed or angry while **это уже чересчур** is a more laid-back "now that would be going too far". | Well, the difference is in negative form:
For example, *Он не слишком умён* means *He's silly*. Yet negative *не чересчур* is almost never used except questions: *А не чересчур ли он умён?* etc.
Also *с лишком* literally means *with excess*, so if written as a whole *слишком* is an adverb, but separate *с лишком* is a noun.
**UPD.**
The etimology of "*чересчур*" is much more vague. First of all, of course, *чересчур* = *через чур*, but what is *чур*, anyway?
Certainly, we have the word *чур* as a part of "a guard spell" against the evil: *чур меня!* Also consider the verb *чураться* (to keep away, to shun). Still it helps a little, because *the meaning* of it is unknown. One option could be, for example, *Чур / Щур* (cf. *Пращур*) = *Ancestor* (so *Чур меня!* means smth. like *Ancestors [defend] me!*), but Vasmer dictionary gives this as "unlikely".
Another point is that *чур меня!* and *чересчур* may be not related in any way. Vasmer says that the word *Чур*, meaning a kind of *Limit* or *Bar*, is to be *reconstructed from* the word *Чересчур*. Personally I know only one appearance of the word *чур* in this sense: *Чуры не знать* means *To have no limits* (especially when someone eats too much). But it's a dialectal expression, and I'm not sure if *чересчур* is really related to *чуры не знать*. |

] | This is recognising good old **OMR (optical mark recognition)**.
The solution varies depending on the quality and consistency of the data you get, so noise is important.
Using an image processing library will clearly help.
**Simple case: No skew in the image and no stretch or shrinkage**
Create a horizontal and vertical profile of the image. i.e. sum up values in all columns and all rows and store in arrays. for an image of MxN (width x height) you will have M cells in horizontal profile and N cells in vertical profile.
Use a thresholding to find out which cells are white (empty) and which are black. This assumes you will get at least a couple of entries in each row or column. So black cells will define a location of interest (where you will expect the marks).
Based on this, you can define in lozenges in the form and you get coordinates of lozenges (rectangles where you have marks) and then you just add up pixel values in each lozenge and based on the number, you can define if it has mark or not.
**Case 2: Skew (slant in the image)**
Use fourier (FFT) to find the slant value and then transform it.
**Case 3: Stretch or shrink**
Pretty much the same as 1 but noise is higher and reliability less. | I am not familiar with Java, but in Python, you can use the imaging library to open the image. Then load the height and the widths, and segment the image into a grid accordingly, by Height/Rows and Width/Cols. Then, just look for black pixels in those regions, or whatever color PIL registers that black to be. This obviously relies on the grid like nature of the data.
Edit:
Doing Edge Detection may also be Fruitful. First apply an edge detection method like something from wikipedia. I have used the one found at archive.alwaysmovefast.com/basic-edge-detection-in-python.html. Then convert any grayscale value less than 180 (if you want the boxes darker just increase this value) into black and otherwise make it completely white. Then create bounding boxes, lines where the pixels are all white. If data isn't terribly skewed, then this should work pretty well, otherwise you may need to do more work. See here for the results: <http://imm.io/2BLd>
Edit2:
Denis, how large is your dataset and how large are the images? If you have thousands of these images, then it is not feasible to manually remove the borders (the red background and yellow bars). I think this is important to know before proceeding. Also, I think the prewitt edge detection may prove more useful in this case, since there appears to be less noise:
The previous method of segmenting may be applied, if you do preprocess to bin in the following manner, in which case you need only count the number of black or white pixels and threshold after some training samples.

This is OMR and you will find it much easier to get good consistent results with a good image processing library. www.leptonica.com is a free open source 'C' library that would be a very good place to start. It could process the skew and thresholding tasks for you. Thresholding to B/W would be a good start.
Another option would be IEvolution - <http://www.hi-components.com/nievolution.asp> for .NET.
To be successful you will need some type of reference / registration marks to allow for skew and stretch especially if you are using document scanning or capturing from a camera image. |

6,335,408 | I have a perhaps silly question... I am trying to determine what is the best approach for typing a property whose value will be either "New" or "Used". Do I use an `enum` or should I just go with a `boolean` (e.g. IsNew)? If I go with `enum`, what should I call this type and property name? (public NewOrUsed NewOrUsed {get; set;} <-- confusing)
Obviously, with `enum` I can have state that declares neither value (NONE, NEW, USED) and `enum` is more future-proof (although one can claim there is no chance other values will exist). Again, what is the appropriate name for such a type and property?

Not really. You have no idea what the future will bring. If you need to change it later, then change it. So, [KISS](http://en.wikipedia.org/wiki/KISS_principle). Go with:
```
public bool IsNew { get; set; }
```

1,015,113 | I tried using dig and I got the error in the title.
My /etc/resolv.conf is this
```
nameserver 67.207.67.2
nameserver 67.207.67.3
nameserver ns1.name.com
nameserver ns2.name.com
nameserver ns3.name.com
nameserver ns4.name.com
```
The first two are the default digital ocean dns, the other are for my domain registrar.
So I tried to add two cloudflare dns, and the file is this:
```
nameserver 1.1.1.1
nameserver 1.0.0.1
nameserver 67.207.67.2
nameserver 67.207.67.3
nameserver ns1.name.com
nameserver ns2.name.com
nameserver ns3.name.com
nameserver ns4.name.com
```
After I did, dig still didn't work.
But if I comment the \*name.com nameservers, dig works:
```
nameserver 1.1.1.1
nameserver 1.0.0.1
nameserver 67.207.67.2
nameserver 67.207.67.3
#nameserver ns1.name.com
#nameserver ns2.name.com
#nameserver ns3.name.com
#nameserver ns4.name.com
```
The fact is that if I comment these \*name.com nameservers, my site went (**and still is, trying do fix**) down after some minutes.
So how can I leave these \*name.com nameservers and be able to use dig and nslookup and stuff like that?
EDIT:
users below noticed that I must have misconfigured something in my site. And it's true. I noticed that there is a "domain" setting in digitalocean panel, and I never configured that. Now I did it and also changed the nameservers of my registrar to the digitalocean nameserver. Now I should only wait for nameserver propagation I guess?

] | Not sure why you are trying to do it, but putting your registrar's servers in your resolv.conf is almost certainly the wrong thing to do.
Likewise, putting in the DNS names into a resolv.conf is the wrong thing to do. The resolv.conf is used to define servers that translate names to IP. If you commented out the other servers, how are you expecting DNS to work at all? How would your dns client know what IP to connect to `ns1.name.com` to attempt to resolve a name?
The `nameserver` directive in the resolv.conf should have IP addresses. (see the man excerpt below).

You should not try to leave them. Having them there is wrong. Instead you should figure out the '**real**' problem and fix that.
Perhaps you need to run a local DNS server with a 'forward zone' for some reason, so that your domain is always redirected to your registrar. Perhaps you have improperly configured your DNS somewhere else. You need to find and fix that.
If it was me, I would probably remove those lines and then start a tcpdump session in screen/tmux and watch all DNS traffic. Wait for whatever failure you are seeing to happen. Then look at see what DNS requests are failing. Then fix them.
The command you might want to use to have a long-running dns capture with tcpdump command like this.
```
tcpdump -ni any port 53 | tee dns_problem.log
```

10,226 | I'm trying to get the cdf from a pdf, which, according to [this MIT open courseware video](https://www.youtube.com/watch?v=wQ6Q9W3Y1ZE), is as simple as getting integral from -$\infty$ to $\infty$. Like this:
$$
F\_z(z) = \int\_{-\infty}^\infty f\_z(z)dz\, = 1
$$
And that works for functions like this: $f\_x(X)$
But what about a function like this $f(X;\beta)$?
Yeah, this is a homework problem, so I don't expect an exact answer, but hopefully some general principles. I have a hard time googling to learn how to do this because I don't know what to call this kind of function $f(X;\beta)$, and I don't know how to type a $\beta$ into google.
The pdf I have is:
$$
f(X;\beta)=
\begin{cases}
\frac {e^{-X/\beta}}{\beta}, & \ X\geq0 \\
0, & \text{otherwise}
\end{cases}
$$
and the cdf it comes out to is:
$$
f(X;\theta)=1-e^{-X/\beta}
$$
Part of my question is also, why did the $f(X;\beta)$ become $f(X;\theta)$? | 2016/01/15 | [

] | CDF = integral of PDF from $-\infty$ to $x$, or:
$F\left(x\right) = \int\_{-\infty}^{x} f\left(u\right) du$.
Functions like $f\left(x;\beta\right)$ take $\beta$ as the parameters, the $\beta$ index *different* probability density functions. You don't need to integrate over them to get the CDF.
$F\left(x;\beta\right) = \int\_{-\infty}^{x} f\left(u;\beta\right)du$. | In addition to what John said (I would have commented on his answer, but don't have enough reputation). And this is not conditional, conditional would be $f(X|\beta)$
$$ F\_X(x;\beta) = P(X \leq x; \beta=\theta) = \int\_{-\infty}^{x} f\_X(x;\beta) dx $$
We fix $x=u$ and $\beta=\theta$
$$ P(X \leq u; \theta)=\int\_{-\infty}^u f\_X(u;\theta) du $$
$$ = \int\_{- \infty}^0 f(u;\theta) du + \int\_0^x f(u; \theta) du $$
$$ = 0 + \int\_0^x \frac{e^{-u/\theta}}{\theta} du $$
$$ = 1 - e^{-x/\theta}$$
Then over the set $X$ and and at particular values $\beta=\theta$
$$ F\_X(X;\theta) = 1 - e^{-X/\beta}$$ |

] | A volatile table stores the data physically. You can access that data multiple times during your session. With a View the data is collected every time you access it.
To help speed up queries on views, you can use Join Indexes on Teradata. They physically store the results of a certain select and maintain it when the underlying data is changed (insert, update, delete) automatically - like most of things on a Teradata. | Also the volatile table holds the data in it for the session. If the data in the source-table changes, it does not automatically change it in the volatile table. View would automatically include the changes as it simply re-runs the SQL on the source-tables. |

] | A volatile table is a temporary table that is only held until the end of session. This is created by default in your "personal schema" and consumes your spool space to maintain.
A view is an object that is permanent across sessions, generates from tables existing in the environment you are in, and does not consume spool space continuously.
Generally speaking I use volatile tables to upload from scripts so that I can process information and drop table easily at the end of a session. I use views to change the way a user sees information that resides in other tables or to restrict access to information to certain users without altering root tables. | Also the volatile table holds the data in it for the session.

Extra : how to read the error (Full Error Dump Attached in the end)
-------------------------------------------------------------------
Step 1 : Locate the start
-------------------------
```
I/flutter ( 4228): ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════
```
Step 2: Locate the end
----------------------
```

```
Step 3: read the error
----------------------
scan the error with your eyes you will see some phrases like

I/flutter ( 4228): Summary 1: RenderCustomMultiChildLayoutBox object was given an infinite size during layout.
```
---
Step 4 :decide what is the type of the
--------------------------------------
this is a ***box constraints*** error
* read more :
+ [Dealing with box constraints - Flutter](https://flutter.dev/docs/development/ui/layout/box-constraints)
+ [BoxConstraints class - rendering library - Dart API](https://api.flutter.dev/flutter/rendering/BoxConstraints-class.html)

Step 5 :how to know what widget is throwing the error
-----------------------------------------------------
go near the end it will give you the source:
```
I/flutter ( 4228): creator: CustomMultiChildLayout ← TimeSeriesChart ← SimpleTimeSeriesChart ← Expanded ← Row ← Column
I/flutter ( 4228): ← [root]
```
* so it is inside the TimeSeriesChart
Step 6 : what is missing
------------------------
go near the end it will give you the missing constraint
```
I/flutter ( 4228): constraints: BoxConstraints(w=120.0, 0.0<=h<=Infinity)
```
* notice : ***0.0<=h<=Infinity***
* the ***height*** can't be Infinity
Step 7 :
--------
* warp the source with a **SizedBox** to make sure it' what throwing the error , to see if it solve it
* [SizedBox](https://api.flutter.dev/flutter/widgets/SizedBox-class.html)
>

>
>
>
Step 8 :
--------
1. the TimeSeriesChart(child) asked Raw(parent) for height
2. the Raw(child) asked Column(parent) for height
3. the Column doesn't know
4. by why the Column doesn't know, because by default behavior is that it will leave it for the children to decide thir own height
5. but we can tell the Column that the children doesn't know so expand them to the available space

Explanation is that the `Column` when created will provide *infinity constraints* to its children and when you wrap any child in a `Flexible` widget, it will act accordingly to the available space (and some of the properties, if any).
The `Row` acts exactly the same way, but horizontally. Here, you are properly adding the `Expanded` to the `Row` child, but then, it tries to find *how much* cant it expand to size itself, and the `Row` doesn't know because it still has an unbounded height from the parent (`Column`), that's why you should use the `Expanded` or even a `Flexible` if you don't need to fit the available space. |

] | You should not use `label:checked`, but `input:checked` for a checked checkbox. Furthermore you use the sibling selector, but the element you want to style is the parent (label is the parent of input). There is no parent selector in CSS, so my solution would be to use a `span` around the text.
```
<label for="radio-selection-range-rows" class="radio-custom-label">
<input class="radio-custom input-group-field" id="radio-selection-range-rows" name="radio-selection" type="radio" checked="checked">

```
input:checked ~ span {

1,266,279 | So recently I've been tweaking my computer's registry for its Memory Management. I know its a bad thing to do to edit your registry without knowing what it may cause to your system but i've only touched a specific registry value which is the `SecondLevelDataCache` in `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management`
I've "accidentally" set its value to 512 Hexadecimal(1298 decimal) instead of 512 Decimal. My CPU's L2 Cache can only do 2x256 KB(Intel I3 2nd Gen 2330M).
So far I've seen faster responses from the system when I set it on 512 Hexa.
Not only that, I've also tried playing games and running applications and also observed better performance from them overall.
And now my question is, what might be a problem later on for this setting if I left it on? What might it cause to my hardware/OS if it were to be left like that that? | 2017/11/07 | [

] | According to [canonical source](https://technet.microsoft.com/en-us/library/cc938581.aspx), the `SecondLevelDataCache` entry has no effect on performance. As a computer science bachelor I'm aware that modern CPU caches are invisible (transparent) to operating systems, optimizing RAM access automatically.
You may never know if you have really observed a performance "boost". Have you run any benchmarks and compared the result?
Nevertheless, keeping your modified value of `SecondLevelDataCache` probably does no harm to your hardware and user experience. | Windows will use the value here IF it cannot resolve the L2 cache size from the HAL (Hardware Abstraction Layer).

86,694 | The Scottish Claim of Right makes clear that the people of Scotland are Sovereign, not Westminster.
However, under the rest of UK law, Westminster/Parliament is Sovereign.
Given the Supreme Court has ruled that the Scottish Parliament can't hold a referrendum on Scottish Independence without Westminster's permission, could the Scottish Government choose to overrule this (or at least attempt to) by asserting the Claim of Right?

In other words, it provides that the monarchy is not absolute, and that its power is circumscribed by parliament.
One thing it certainly does not do is circumscribe the power of the Westminster parliament, which had no power in Scotland before the Acts of Union of 1707. Before then, the Westminster parliament was only the Parliament of England. The Acts of Union provided, in part,
>
> That the United Kingdom of Great Britain be Represented by one and the same Parliament to be stiled the Parliament of Great Britain
>
>
>
With that act, the Parliament of Great Britain assumed the role of the Parliament of Scotland. As a consequence, the Claim of Right Act of 1689 *grants power to* the Westminster parliament rather than circumscribing its power. To the extent the people are sovereign, this sovereignty is vested in their representatives in Westminster.
On the other hand, if you're talking about [the 1989 claim](https://en.wikipedia.org/wiki/Claim_of_Right_1989), that document

> | The 1989 Claim of Right cannot be used by the Scottish Government to hold another referendum on independence for the same reasons that the Scottish Government cannot do so under the Scotland Act 1998: they (and by extension, the Scottish Parliament) lack the competence to do so.
This was decided by the UK Supreme Court in [*Devolution issues under the Scotland Act 1998, Reference by the Lord Advocate (Rev1)* [2022] UKSC 31](https://www.supremecourt.uk/cases/uksc-2022-0098.html) where the Court held (at 77-82) that a proposed referendum on independence would concern a reserved matter: namely, the Union of Scotland and England. A reserved matter is exclusively within the competence of the United Kingdom Parliament unless it chooses to devolve or delegate some or all of the matter to one of the devolved parliaments.
In this case, [Section 29 of the Scotland Act 1998](https://www.legislation.gov.uk/ukpga/1998/46/section/29) states:
>
> (1) An Act of the Scottish Parliament is not law so far as any
> provision of the Act is outside the legislative competence of the
> Parliament.
>
>
> (2) A provision is outside that competence so far as any of the
> following paragraphs apply—
>
>
> ...
>
>
> (b) it relates to reserved matters
>
>
>
where a reserved matter is defined in [Schedule 5, Part 1, Section 1 of the Scotland Act 1998](https://www.legislation.gov.uk/ukpga/1998/46/schedule/5) as including, amongst other things:
>
> The following aspects of the constitution are reserved matters, that
> is—
>
>
> ...
>
>
> (b) the Union of the Kingdoms of Scotland and England
>
>

In the *Devolution (Rev1)* case, the Supreme Court held (at 92) that the proposed independence referendum question related to a reserved matter and so was outwith the Scottish Parliament's competence.
The Supreme Court also considered the principle of self-determination as established in international law, which is relevant to the matter at the heart of the Claim of Right. Namely, that the people of Scotland are sovereign and have the right to determine their own independence and so on.
The Court held (at 88-89) that self-determination was expected to occur within the existing framework of the state, per the Supreme Court of Canada in *Reference re Secession of Quebec* [1998] 2 SCR 217 and UN opinion on the matter of Kosovo in Written Proceedings in relation to UN General Assembly Resolution 63/3 (A/RES/63/3) (8 October 2008).
>
> 88. In its judgment the Supreme Court explained (at paras 136-137) that Canada was a sovereign and independent state conducting itself in compliance with the principle of equal rights and self-determination of peoples and thus possessed of a government representing the whole people belonging to the territory without distinction. It considered that the then current constitutional arrangements within Canada did not place Quebecers in a disadvantaged position within the scope of the international law rule. It continued:
>
>
> “In summary, the international law right to self-determination only generates, at best, a right to external self-determination in situations of former colonies; where a people is oppressed, as for example under foreign military occupation; or where a definable group is denied meaningful access to government to pursue their political, economic, social and cultural development. In all three situations, the people in question are entitled to a right to external self-determination because they have been denied the ability to exert internally their right to self-determination. Such exceptional circumstances are manifestly inapplicable to Quebec under existing conditions.” (at para 138)
>
>
> It went on to say that in other circumstances peoples were expected to
> achieve self-determination within the framework of their existing
> state:
>
>
> “A state whose government represents the whole of the people or
> peoples resident within its territory, on a basis of equality and
> without discrimination, and respects the principles of

>
>
> 89. In our view these observations apply with equal force to the position
> of Scotland and the people of Scotland within the United Kingdom. ... The submission went on to state that international law does not, in general, prohibit secession; but the relevant point, in relation to the intervener’s submission based on a right of self-determination under international law, is the absence of recognition of any such right outside the contexts described by the Supreme Court of Canada, none of which applies to Scotland.
>
>
>
On this basis, the Claim of Right 1989 is doomed to fail because any self-determination has to operate within the existing framework of the United Kingdom's political hiercharcy and constitution, and the Supreme Court has made it clear that the Union is a reserved matter, so the United Kingdom Parliament must give explicit permission for any proposed Bill or legal mechanism that affects that. |

] | `master`, like `origin` or `upstream`, is a convention, not a requirement. Since you have no commits in `master`, you have no refs for it either. `HEAD` is pointing to a ref that does not yet exist. When you run `git checkout -b branch`, you ask git to:
1. Duplicate the ref your `HEAD` points to.
2. Point your `HEAD` to the new ref.
Since your `HEAD` points to a nonexistent ref, you duplicate nothing and end up still pointing to nothing. As long as you continue to switch branches without committing, this will be the case.
Once you've made your first commit everything changes. Now that you've made a commit, you have a ref for your current `HEAD` to point to. The next time you create a branch, there's a ref to duplicate, so the branch won't disappear next time you switch.
Example(ish):
```
git init
touch test
git add test
# There are no refs at this point, but HEAD is pointing to the nonexistent refs/heads/master
git checkout -b new_branch
git checkout master # fails, no refs (for master)
git checkout -b new_branch2
git checkout new_branch # fails, no refs (for new_branch)
git commit -m "Initial commit."
# Now you have a ref for new_branch2, but not yet for any other branches.
git checkout -b new_branch3 # new_branch2's ref is duplicated
git checkout new_branch2 # success, you made a commit in this branch so it has a ref
git checkout new_branch3 # success, you made a commit in new_branch2 which this branch's ref is also pointing to.
git checkout master # failure, until you run with '-b' master doesn't have any refs yet.

You can use `add_hotkey()` and it doesn't need `wait()`
```

currentSong = "idk"
exit = False # make a loop control variable
def alt_k():
print('pressed: alt+k')
i = 1
paused = False
def alt_q():
global exit # need it to assign `True` to global/external variable instead of creating local variable
print('pressed: alt+q')
exit = True
def alt_s():
print('pressed: alt+s')
if currentSong not in listedSongs:
listedSongs.append(currentSong)
print(listedSongs)
keyboard.add_hotkey('alt+k', alt_k)
keyboard.add_hotkey('alt+q', alt_q)
keyboard.add_hotkey('alt+s', alt_s)
# main loop
while not exit:
time.sleep(1)
```
See examples in documentation: [Example](https://github.com/boppreh/keyboard#example)
---
Eventually you may use `hotkye = read_hotkey(...)` with `if/else` to execute correct function.
I'm not sure but sometimes it works for me also with `hotkey = keyboard.wait(suppress=False)` but sometimes it doesn't work.
```
while not exit:
hotkey = keyboard.read_hotkey(suppress=False)
#hotkey = keyboard.wait(suppress=False)
print('hotkey:', hotkey)
if hotkey == 'alt+k':
alt_k()
elif hotkey == 'alt+q':
alt_q()
``` | This is how I solved my issue.
I ditched the keyboard module since it was not working the way I wanted it to and then I used the [Python Global-Hotkeys Module](https://pypi.org/project/global-hotkeys/). The code was pretty much the same but now everything just clicked in place.

Option 1:
Drill down into the response object using JMES on the dynamodb specific response object:
```
response object = {
"Items":[
{
"Date":{
"N":"54675846"
},
"Message":{
"S":"Message02"

"_id":{
"S":"4567"

"Category":{
"S":"Validation Error"

]}
filtered_iterator = response_iterator.search("Items[?Category.S == 'Validation Error'].{_id: _id, Category: Category, Date: Date, IsRead: IsRead, Message: Message, Email: Email}")
```
You can then iterate over the response object pages as usual with a standard for loop.
Option 2:
Use list comprehension on the paginated response object and filter at that point. Note that this will be the more expensive option as it will still scan and return the max items within your paginator configutration:
```
for page in response_iterator:
page["Items"] = [x for x in page["Items"] if '{search_term}' in x['Category']['S']]

```
pm2cpio bpmdj-4.2.pl2-0.x86_64.rpm|cpio -idv

] | At the site DaveParillo suggested I've found [BpmDj](http://bpmdj.yellowcouch.org/measuring-tempo.html) project. It has a `bpmcount` executable that calculates the bpm very nice: it handles mp3 as well as flac:
```
161.135 Metallica/2008 - Death Magnetic/01-That Was Just Your Life.flac
63.5645 Doom3.mp3
```
The only thing that's left is to retag the collection. I'll update this answer whenever I succeed.
Thanks! :)
---
**Step 1**
Run `bpmcount` against the entire collection and store the results into a textfile.
The problem is that `bpmcount` crashes from time to time and tries to eat up to 2GB of memory when it processes several files so we should feed it with filenames one by one. Like this:
```
musicdir='/home/ootync/music'
find "$musicdir" -iregex ".*\.\(mp3\|ogg\|flac\|ape\)" -exec bpmcount {} \; \
| fgrep "$musicdir" > "$musicdir/BPMs.txt"
```
---
**Step 2**
We'll need some additional packages: `apt-get install vorbis-tools flac python-mutagen`.
Now have a look at how the 'bpm' tag can be added:
```
mid3v2 --TBPM 100 doom3.mp3
vorbiscomment -a -t "BPM=100" mother.ogg
metaflac --set-tag="BPM=100" metallica.flac
```
Alas, I have no \*.ape tracks
Now we have the BPMs and the entire collection should be retagged. Here's the script:
```
cat "$musicdir/BPMs.txt" | while read bpm file ; do
bpm=`printf "%.0f" "$bpm"` ;
case "$file" in
*.mp3) mid3v2 --TBPM "$bpm" "$file" > /dev/null ;;
*.ogg) vorbiscomment -a -t "BPM=$bpm" "$file" ;;
*.flac) metaflac --set-tag="BPM=$bpm" "$file" ;;
esac
done
```
---
**Step 2.1 Revisited**
Here's a script that will add BPM tags to your collection.
It runs one process per CPU Core to make the process faster. Additionally, it uses no temporary files and it capable of detecting whether a file is already tagged.
Additionally, I've discovered that FLAC sometimes has both ID3 and VorbisComment inside. This script updates both.

**Step 1**
Run `bpmcount` against the entire collection and store the results into a textfile.
The problem is that `bpmcount` crashes from time to time and tries to eat up to 2GB of memory when it processes several files so we should feed it with filenames one by one. Like this:
```
musicdir='/home/ootync/music'
find "$musicdir" -iregex ".*\.\(mp3\|ogg\|flac\|ape\)" -exec bpmcount {} \; \
| fgrep "$musicdir" > "$musicdir/BPMs.txt"
```
---
**Step 2**
We'll need some additional packages: `apt-get install vorbis-tools flac python-mutagen`.
Now have a look at how the 'bpm' tag can be added:
```
mid3v2 --TBPM 100 doom3.mp3
vorbiscomment -a -t "BPM=100" mother.ogg
metaflac --set-tag="BPM=100" metallica.flac
```
Alas, I have no \*.ape tracks
Now we have the BPMs and the entire collection should be retagged. Here's the script:
```
cat "$musicdir/BPMs.txt" | while read bpm file ; do
bpm=`printf "%.0f" "$bpm"` ;
case "$file" in
*.mp3) mid3v2 --TBPM "$bpm" "$file" > /dev/null ;;
*.ogg) vorbiscomment -a -t "BPM=$bpm" "$file" ;;
*.flac) metaflac --set-tag="BPM=$bpm" "$file" ;;
esac
done
```
---
**Step 2.1 Revisited**
Here's a script that will add BPM tags to your collection.
It runs one process per CPU Core to make the process faster. Additionally, it uses no temporary files and it capable of detecting whether a file is already tagged.
Additionally, I've discovered that FLAC sometimes has both ID3 and VorbisComment inside. This script updates both.

] | This is a command-line tool to detect the BPM and put it in the FLAC file tags:
<http://www.pogo.org.uk/~mark/bpm-tools/> | I found another tool for tagging MP3 files with the correct BPM value.
It's called [BPMDetect](http://sourceforge.net/projects/bpmdetect/). Open-source. QT libs so works fine under Gnome. Comes with a GUI but can be compiled as a console only version (run "scons console=1" as stated in the readme.txt).
Otherwise, in the end, i've too used the "bpmcount" from BpmDJ as i had difficulties to compile BPMDetect on a 64 bits Ubuntu host (due to the fmodex dependency). So i took the (very cool and well-written) shell script above (see below), the "bpmcount" binary extracted from the [x64 .rpm][3] available on the BpmDJ website (i've just extract the .rpm with
```
pm2cpio bpmdj-4.2.pl2-0.x86_64.rpm|cpio -idv
```
and it worked like a charm. I just had to modify the above script as, out of the box, it weren't working on my side (problem with stdout / stderr of the bpmcount binary). My modification is about file redirection :
```
local bpm=$(bpmcount "$file" 3>&1 1>/dev/null 2>&3 | grep '^[0-9]' | cut -f1)
``` |

Enjoy! :) | To get @meridius' solution working on my Mac I had to do a bit of extra legwork and modify the script a bit:
```
# Let's install bpm-tools
git clone http://www.pogo.org.uk/~mark/bpm-tools.git
cd bpm-tools
make && make install
# There will be errors, but they did not affect the result
# The following three lines could be replaced by including this directory in your $PATH
ln -s <absolute path to bpm-tools>/bpm /usr/local/bin/bpm
ln -s <absolute path to bpm-tools>/bpm-tag /usr/local/bin/bpm-tag
ln -s <absolute path to bpm-tools>/bpm-graph /usr/local/bin/bpm-graph
cd ..
# Time to install a bunch of GNU tools
# Not all of these packages are strictly necessary for this script, but I decided I wanted the whole GNU toolchain in order to avoid this song-and-dance in the future
brew install coreutils findutils gnu-tar gnu-sed gawk gnutls gnu-indent gnu-getopt bash flac vorbis-tools
brew tap homebrew/dupes; brew install grep
# Now for Mutagen (contains mid3v2)
git clone https://github.com/nex3/mutagen.git
cd mutagen
./setup.py build
sudo ./setup.py install
# There will be errors, but they did not affect the result
cd ..
```
Then I had to modify the script to point to the GNU versions of everything, and a few other tweaks:
```
#!/usr/local/bin/bash
# ================================= FUNCTIONS =================================
function help() {
less <<< 'BPMWRAP
Description:
This BASH script is a wrapper for bpm-tag utility of bpm-tools and several
audio tagging utilities. The purpose is to make BPM (beats per minute)
tagging as easy as possible.
Default behaviour is to look through working directory for *.mp3 files
and compute and print their BPM in the following manner:
[current (if any)] [computed] [filename]
Usage:
bpmwrap [options] [directory or filenames]
Options:
You can specify files to process by one of these ways:
1) state files and/or directories containing them after options
2) specify --import file
3) specify --input file
With either way you still can filter the resulting list using --type option(s).
Remember that the script will process only mp3 files by default, unless
specified otherwise!
-i, --import file
Use this option to set BPM tag for all files in given file instead of
computing it. Expected format of every row is BPM number and absolute path
to filename separated by semicolon like so:
145;/home/trinity/music/Apocalyptica/07 beyond time.mp3
Remember to use --write option too.
-n, --input file
Use this option to give the script list of FILES to process INSTEAD of paths
where to look for them. Each row whould have one absolute path.
This will bypass the searching part and is that way useful when you want
to process large number of files several times. Like when you are not yet
sure what BPM limits to set. Extension filtering will still work.
-o, --output file
Save output also to a file.
-l, --list-save file
Save list of files about to get processed. You can use this list later
as a file for --input option.
-t, --type filetype
Extension of file type to work with. Defaults to mp3. Can be specified
multiple times for more filetypes. Currently supported are mp3 ogg flac.
-e, --existing-only
Only show BPM for files that have it. Do NOT compute new one.
-w, --write
Write computed BPM to audio file but do NOT overwrite existing value.
-f, --force
Write computed BPM to audio file even if it already has one. Aplicable only
with --write option.
-m, --min minbpm
Set minimal BPM to look for when computing. Defaults to bpm-tag minimum 84.
-x, --max maxbpm
Set maximal BPM to look for when computing. Defaults to bpm-tag maximum 146.
-v, --verbose
Show "progress" messages.
-c, --csv-friendly
Use semicolon (;) instead of space to separate output columns.
-h, --help
Show this help.
Note:
Program bpm-tag (on whis is this script based) is looking only for lowercase
file extensions. If you get 0 (zero) BPM, this should be the case. So just
rename the file.

] | At the site DaveParillo suggested I've found [BpmDj](http://bpmdj.yellowcouch.org/measuring-tempo.html) project. It has a `bpmcount` executable that calculates the bpm very nice: it handles mp3 as well as flac:
```
161.135 Metallica/2008 - Death Magnetic/01-That Was Just Your Life.flac
63.5645 Doom3.mp3
```
The only thing that's left is to retag the collection. I'll update this answer whenever I succeed.
Thanks! :)

**Step 1**
Run `bpmcount` against the entire collection and store the results into a textfile.
The problem is that `bpmcount` crashes from time to time and tries to eat up to 2GB of memory when it processes several files so we should feed it with filenames one by one. Like this:
```
musicdir='/home/ootync/music'
find "$musicdir" -iregex ".*\.\(mp3\|ogg\|flac\|ape\)" -exec bpmcount {} \; \
| fgrep "$musicdir" > "$musicdir/BPMs.txt"
```
---
**Step 2**
We'll need some additional packages: `apt-get install vorbis-tools flac python-mutagen`.
Now have a look at how the 'bpm' tag can be added:
```
mid3v2 --TBPM 100 doom3.mp3
vorbiscomment -a -t "BPM=100" mother.ogg
metaflac --set-tag="BPM=100" metallica.flac
```
Alas, I have no \*.ape tracks
Now we have the BPMs and the entire collection should be retagged. Here's the script:
```
cat "$musicdir/BPMs.txt" | while read bpm file ; do
bpm=`printf "%.0f" "$bpm"` ;
case "$file" in
*.mp3) mid3v2 --TBPM "$bpm" "$file" > /dev/null ;;
*.ogg) vorbiscomment -a -t "BPM=$bpm" "$file" ;;
*.flac) metaflac --set-tag="BPM=$bpm" "$file" ;;
esac
done
```
---
**Step 2.1 Revisited**
Here's a script that will add BPM tags to your collection.
It runs one process per CPU Core to make the process faster. Additionally, it uses no temporary files and it capable of detecting whether a file is already tagged.
Additionally, I've discovered that FLAC sometimes has both ID3 and VorbisComment inside. This script updates both.

129,041 | Amarok 2 can search through music collection using ID3v2 tag's 'bpm' field. That would be *very* nice to retag the entire music collection so I can find the 'mood' of the track I like.
However I've not found any beat-detection software that could have helped me. Have you ever used one? CLI, preferably. Also I'm interested if there's anything alike for tagging FLACs with the same 'bpm' field.

Enjoy! :) | While it is not just a tool like you say you are looking for, [Banshee media player](http://banshee-project.org/ "Banshee website") can detect bpm.
I use Banshee for all my music playing, organisation and synchronizing to portable players.
I'm not affiliated, but I like the program the best of all that I've tried.
It can also generate "smart playlists" based on all sorts of properties of the tracks, including bpm.
There is an extension which analyses all sorts of things about the song, and will find similar songs to the one you're playing. It's called [Mirage](http://hop.at/mirage/ "Mirage website"), and I used it for a while, but I don't any more, as I've created a number of playlists of ones that suit various moods (not necessarily similar according to Mirage).
I don't know if Banshee will save the bpm it detected back into the ID3v2 "bpm" tag of the file. If anyone knows how to easily check the bpm tag from outside the program I'll check. |

] | In addition to the tips from Joe's great grandmother, you might want to try and rinse the pasta thoroughly with some lukewarm water after cooking it al dente. That way you rinse off the remaining starch and you prevent the pasta from cooking any further. Rinsing results in firmer pasta that is silky smooth and doesn't clump together or get mashed up. Your scoop or tongs will slither right through without damaging the pasta. :) | Here's how I learned from my great grandmother:
* cook the bacon/salt pork/home/whatever 'til crispy
* beat the eggs (she used whole eggs) with a little black pepper
* drain the cooked pasta, and immediately mix the pasta with the eggs; if it's too dry, add some of the pasta water.
* Add fried pork product and mix a litle more.
* sprinkle cheese on top while serving.
...
But I've also been known to mix everything but the pasta together (maybe not the pork if it's still too hot), and then toss it all together while the pasta's still hot, kinda like if you were tossing to mix the dressing on a salad. (tongs work really well)
...
Either way, you do end up with the fried pork bits at the bottom of the pot you were mixing in. The easy way around this is to save 1/3 to 1/2 of it, and sprinkle it over the top when serving. |

But I've also been known to mix everything but the pasta together (maybe not the pork if it's still too hot), and then toss it all together while the pasta's still hot, kinda like if you were tossing to mix the dressing on a salad. (tongs work really well)
...
Either way, you do end up with the fried pork bits at the bottom of the pot you were mixing in. The easy way around this is to save 1/3 to 1/2 of it, and sprinkle it over the top when serving. | You could try replacing spaghetti with rigatoni pasta.
In this way it is a lot easier to mix and you'll end up with a dish much closer to the authentic Italian carbonara recipe. |

] | Here's how I learned from my great grandmother:
* cook the bacon/salt pork/home/whatever 'til crispy
* beat the eggs (she used whole eggs) with a little black pepper
* drain the cooked pasta, and immediately mix the pasta with the eggs; if it's too dry, add some of the pasta water.
* Add fried pork product and mix a litle more.
* sprinkle cheese on top while serving.

Do not ever rinse the pasta with water!
Also, if you are making Carbonara with anything other than Guanciale (pork cheek)--Shame on you!

] | In addition to the tips from Joe's great grandmother, you might want to try and rinse the pasta thoroughly with some lukewarm water after cooking it al dente. That way you rinse off the remaining starch and you prevent the pasta from cooking any further. Rinsing results in firmer pasta that is silky smooth and doesn't clump together or get mashed up. Your scoop or tongs will slither right through without damaging the pasta. :) | You could try replacing spaghetti with rigatoni pasta.

What am I doing wrong or what am I missing here? How can I import large json files to MongoDB? | 2014/10/05 | [

```

```
**I think there are some mistakes near the end of your imported file.**
For `{"t":"1358836291","p":"1.33481"}`, the offset of second `:` is 21. So, please check syntax of documents near the end (96% ~ 100%) of imported file.
By the way, `--jsonArray` is improper to use here because it has a limit of 16MB. | Change your command from `mongoimport -d woption -c eurusd eurusddata.json --jsonArray` to `mongoimport -d woption -c eurusd --file eurusddata.json --jsonArray` and this will work. Hope this helps. Update if this doesn't work. |
