Current changes
Changes to PfaEdit (predecessor to
FontForge)
Changes to the sfd format.
Changes to create a stub Mac application. Add an apple event handler to fontforge so that it will notice when the finder wants it to open files. Add icons, etc. so it will look like a mac app.
With layers that should all change. We should only set the width if there is nothing in any of the potential foreground layers. Don't count the background layers or the grid psuedo layer. Don't count open contours (might be a secondary guide line layer or something). If we're going to clear a layer before pasting (normal behavior in fontview) then don't count the layer cleared.
Also allow the user to specify exactly how many ligature carets s/he wants rather than just setting a minimum bound.
Also 'lcar' (Apple) output was broken.
Also neither AAT nor OpenType supports negative lig carets, so if the user drags a lig caret line negative, have it stick at 0.
We don't generate version 4 yet, and we won't for a while. Version 4 will include the ability to insert backslash newline into long lines. This is so we can conform to the internet requirements of fewer than 990 bytes on a line. And the delay is so that people don't scream at me for making an incompatible change to the format -- if I give the parser time to perculate through the user community, with luck no one will even notice -- especially as long lines are rare.
Actually it's worse than that, the spec says that if there are too many things on the stack then start parsing the stack from the unexpected end.
Adobe have admitted that the obvious reading of their spec is incorrect (they can't quite bring themselves to say the spec is wrong). So revert some of the way we were parsing type2 charstrings.
(Only do this if font doesn't use these areas).
Fix a couple of other foreground specific things too.
Do something similar for bad transformation matrices (those with members 2 or more (or less than -2)).
(setting is sticky).
glyph.altuni
either None, or a tuple of tuples, one sub-tuple for each alternate. each sub-tuple is (alternate-unicode, variation selector (or -1), reserved for future=0 now).
Provide some icons
Also update the install procedure to put them in the right place.
Preference item containing a directory from which to read icon files
(also boxify the Find Problems dlg).
Also add a bookmark (and back/forward) mechanism.
$ fontforge
http://openfontlibrary.org/people/Nasenbaer/Nasenbaer_-_Widelands.ttf
Also, was a crash bug when mixing a font with a baseline table and a font without one (in the disply dlg).
Element->Insert Text
Outlines)
It adds the text outlines directly (instead of a draw command
using another font) because most fonts can't include text drawing in their
glyphs. Also include a Bind to Path variant.
This could be used to produce a grid of guidelines, or, in conjunction with
Element->Overlap->Intersec
t it could provide a poor man's
"Pattern Fill" (Since Pattern fills are only available in type3 fonts this
sort of makes them work for any font type).
Add python scripting (font.horizontalBaseline, font.verticalBaseline) too.
Add support under Show ATT.
Remove the old vertical origin field.
./configure --enable-type3
is specified, of course.
Also add support for cliping paths
Make fonts containing images work in pdf output.
The big change in this release is that every font database can now contain multiple layers. Before this all layers in a font used the same type of splines and there were only 2 or 3 of them.
Now there may be any number of layers, and each layer can contain different types of splines -- so one database can contain both quadratic and cubic data and can store data for both PostScript and TrueType fonts.
In a normal font all glyphs have the same number of layers (this is not true
in a type3 font, which each glyph may have it's own set of layers). You may
set the number, names and types of layers width the Element->Font
Info->Layers
pane.
In the font view you can select which layer is active (and displayed) with
the View->Layers
menu item. You can copy selected glyphs
of one layer to another (automagically adjusting the spline type if needed)
with Edit->Copy Layer To Layer
. You can compare to layers
for differences with Element->Compare Layers...
.
In the character view the Layers palette has changed. The things which controlled
the visibility of hints have moved to the View->Show
menu
(as have some other entries that used to be in the top level
View
menu). The layers palette solely displays the glyph's layers
and controls which layer is active.
The File->Generate Fonts...
dialog allows you to specify
which layer is to go into the font. Note that many things remain common:
the hints and truetype instructions apply to all layers. GPOS, GSUB, kern,
and morx information is common all layers. The outlines may differ in detail,
but outlines from which a font will be generated should have the same shape.
Add new python stuff to handle layers:
font.layers[1].name = "Foreground" font.layers[0].is_quadratic = TRUE
del font.layers["Extra layer"]
font.layers.add("name",is_quadratic)
(this object has an iterator which returns the names of all layers)
So the command line now takes an --allglyphs argument, and the scripting open commands now take a value of 4 for the openflags argument to mean this.
(If you hold down the <Alt> key when you select the menu item, FF will leave the ellipse it calculated in the background layer. That was a debugging technique but I thought it was kind of interesting and left it in.)
If a line's unit vector is close enough to the font's italic slant, then prefer the unit vector based on the italic slant instead.
Added an experimental mode which allows to build glyph data based on a preexisting hint layout and extend it with additional stems.
(Also provide default values now when [Add]ing private entries in Font Info.
He also tells me that the internationalized weight classes don't get parsed properly.
So instead, when loading and saving a Type2 font use double precision temporaries. This should mean there will be no errors to accumulate. There will be slight errors when converted to SplinePoints, but these errors will not accumulate.
Change the "Ref with bad ttf transformation" so that it checks for integral coordinates too.
Add a problem which will look at the glyphs a lookup is active for, and then checks the script of each glyph against the scripts attached to the features which invoke this lookup. If the script doesn't match anything, then complain.
Barry also complains that spiro points are rounded. This is more debatable. The bezier conversion will put bezier points where there were spiros, so if we don't round the spiros we get non-integral points. But if we do round the spiros we mess up the splines. Hmm.
Add subtables to hold:
This is a finer grain approach, but similar to, the previous one. There we skipped the whole table, presuming it redundant. But in CharisSIL the morx table has a lot of functionality orthogonal to GSUB. So we must parse both.
Make the window open at 33% instead.
- Previously I forgot to mention Alexey's changes in DStems hinting code.
$ ./configure $ make $ make install $ make fontforgegtk $ make install_gtk
About all it can do is open a font and display it. If a menu command does not require a dialog then it might work. There are probably scores of bugs even in the little bit that supposedly does work.
I think the open dialog is extremely ugly. That's not my fault, that's gtk's widget. The open dialog is far less functional than the one in the gdraw fontforge -- I can't figure out how to enhance it.
In theory.
Add python support for the contour_name.
However, they ain't gwana change, so I must. Always dump out an Encoding dictionary even when it shouldn't be needed.
It expected to find spiros in a glyph marked as being edited in spiro mode, and was surprised when none were available.
The new stuff all worked as far back as 10.3 -- but FontForge source is no longer compatible with 10.2.
Edit->Select->Autohintable
$ ./configure --enable-pyextension
More debateable: if we change "f" to "u0066" then change "f.sc" to "u0066.sc" and "f_f_l" to "u0066_u0066_l" (and recurse on those name changes).
So, I'll support this now as my only way of handling type3 style svg fonts with embedded bitmaps.
The standard points out that URIs are limited to 1024 bytes, but I don't pay any attention to that restriction, and will stuff arbetrary sized images into these things.
Also extend fontlint to do validity checking in glyphs against the 'maxp' table. (This won't matter when editing fonts, as ff will fixup the maxp values when it generates the font, but there might be some existing fonts with buggy 'maxp' values).
Added some new members to glyph:
Also the contents of one of the structures has changed a bit, and a value that used to live in one field has moved to another (the ppem value moved from (exc)->size->metrics.x_ppem to (exc)->size->root.metrics.x_ppem.
Well, David warned me that this might happen.
Warn the user (rather than just silently failing) when we have a freetype version mismatch.
The dialog is no longer modal, however it does not get updated with each change to the font (that would make moving a point around in the outline view far too sluggish), instead there is a [Refresh] button the user can press to force an update.
So I've added a Ligature Caret count to the Element->Glyph Info dialog to give the user control over it when necessary.
The first creates a new layer by interpolating between the current layer
and the layer in the first argument.
The second creates a new glyph in the font by interpolating between the first
two arguments. The glyph's unicodecode point and name will be copied from
the first argument (the font must not already contain this glyph).
If amount is 0 the result will look like the first glyph, if 1 then like
the second.
% MF2PT1: bbox 0 90 834 422
where the third (so called) bounding box entry is actually the glyph's advance width. I was reluctant to use this at first, because that clearly isn't something that belongs in a bounding box...
Sigh. Adobe documents a feature file syntax they don't fully support, and even their documented syntax is inadequate to represent all the complexities of OpenType.
FontForge supports anchors and device tables and will parse lookups which contain these. This is a syntax which Adobe documents but does not implement. Adobe also warns that this syntax may change when they get around to implementing it.
FontForge makes one extension to the syntax which allows me to specify complex contextual features.
Neither I nor Adobe support reverse contextual substitutions, nor GDEF mark classes.
File->Merge Kern Info
to
File->Merge Feature Info
Edit->Copy Lookup Data
)
The major change is that fontforge now presents lookups to the user rather than features. I think this makes simple things more difficult (which is why I avoided this when I started), but it makes complex things possible.Sadly the world is not simple.
So when a piece of typographic information is created (a ligature, a kern pair, a glyph substitution, etc.) it must be tagged with a lookup (actually a lookup sub-table) rather than a feature tag.
The lookup itself will be tagged with a feature tag (possibly several tags) and with scripts and languages in which that lookup should be active.
NOTE: This reverses the way GPOS/GSUB think about things, but it contains the same information.The Font Info dialog now contains a Lookup pane which allows you to create and edit lookups and their subtables. You can also reorder them. The order shown in the dialog is the order in which they will be applied.
A mac feature/setting subtable also gets converted into this format.
The Font Info dialog no longer has Anchor Classes, Contextual, or State Machine panes.
Instead you can edit a lookup subtable's data (for any subtable type). There are new dialogs which list all the information for each lookup type (ie. a dialog which lists all kern pairs in a subtable), and these provide access to the old anchor class, contextual or state machine dialogs.
The Glyph Info command has also changed. It looks simpler and more comprehensible (I think), but the act of creating a new substitution has become more complex because (potentially) one must create a new lookup and lookup subtable before doing the simple task of adding a new replacement glyph.
The kerning class, contextual and state machine dialogs have all changed in that they no longer request a feature tag, they now need a lookup subtable.
The metrics view also needs a subtable.
The metrics view has changed considerably.
It displays all the features in the font, and allows you to select which ones you want active in the view. It lets you set the script & language. It will apply lookups that it couldn't handle previously like ligatures and contextuals.It does not do Indic glyph reordering. I'm not sure how to and last I checked MS had not updated their docs to reflect their new procedures.
Many other dialogs now take a lookup subtable where appropriate.
Show ATT has changed, but it is still not editable. I hope that the Lookups pane will do that instead.
There used to be a scripting command which indicated what ligature features got stored in afm files. Now each ligature lookup has a flag set on it which conveys this information.
The Element->Typographic Features menu has been removed. It's functionality has moved into Font Info->Lookups (I hope I've got everything).
Some scripting commands have been removed, others have been changed and others have been added. I apologize for this, as it will break existing scripts, but some basic concepts no longer exist and others, very different, have replaced them. (and anyway people may switch to python scripting now).
- Removed:
DefaultATT ControlAfmLigatureOutput ApplySubstitutions CopyGlyphFeatures AddATT Replaced with AddPosSub RemoveATT GlyphInfo(Position/Pair/Substitution/AltSubs/MultSubs/Ligature) SelectByATT Replaced with SelectByPosSub- Changed
Set(V)Kern takes an optional third argument, a lookup subtable name (if not specified it choses one) AddAnchorClass(name,type,lookup-subtable-name) GetPosSub(subtable-name) AutoKern(spacing,threshold,subtable-name[,kernfile])- Added

New files are tagged as version 2. Old files will still work, but ff will no longer produce file in the old format.
PUSHB_1 1 2
would lose the second number and not complain. In fixing that, I broke the first. Now both should work (I hope).
Pairwise positioning lookups could also get their device table offsets screwed up.
fontforge.FontView.FontSize: 24
[a-z] a b => does nothing a b [a-z] => does nothing a b => substitutes
will only substitute of "ab" is a word all to itself.
Make the "+" operator concatenate arrays
[1,2] + [3,4] == [1,2,3,4] [1,2] + 3 == [1,2,3]
There was no objection.
I have now removed them.
I also made the SetPrefs scripting function sort of work if the user tries to set one of these (it will set the appropriate flags in the default option set used by generate).
The defaults of these flags were different on the Mac from everywhere else. This meant that a script could do different things on the Mac and on linux. That seems like a bad idea. I have changed things so that the default options setting for generate is always OpenType.
THIS IS AN INCOMPATIBLE CHANGE AND SCRIPTS ON THE MAC COULD NOW BEHAVE DIFFERENTLY.
Legacy programs will not work when given a font in the correct format. New programs should be able to handle either correct or broken 'size' features.
A few of Adobe's programs make use of the 'size' feature, and XeTeX does. I know of no others (besides font editors). Both intend to upgrade their programs... So this may be less of an issue than I initially feared.
FontForge should now be able to read in a size feature in either format and gives the user the option of producing 'size' features in either format on output.
Windows won't use a font where the codepages field is 0.
The first sets the start point of each contour to the leftmost point, while the second orders the contours by their leftmost points. This will slightly reduce the size of output charstrings. It will also make more things available to be put in subroutines.
Use the appropriate defn for the version we happen to be outputting.
Both will select all encoding slots containing the named glyph (or unicode value)
Now if the pagesize has not been set, don't specify a PageSize to setpagedevice.
I added the following new scripting functions:
I added the following new scripting functions:
Actually ALL glyphs in a monospace font should default to the mono-space width rather than 1em.
These search all selected glyphs, looking for any references in those glyphs with the given name/unicode value, and then translating the reference by (xoff,yoff) or positioning the reference absolutely at (x,y).
There are two problems with this:
instead figure widths out after all pastes have completed, looking at the use_my_metrics bit to get things right.
Setting this bit should give you a symbol encoding as well as all the other encodings you've set bits for. It doesn't work under windows. It doesn't work. TrueType fonts do not provide a symbol encoding, while 'CFF ' fonts only provide a symbol encoding. But hey, let's support it anyway!
change View->Goto to know about this range as MS Symbol.
On the other hand some people might want to make fonts that only work on macs. So add a configure flag.
(just to scripting)
So the script sub-table of both GPOS/GSUB should contain all scripts used in either (rather than just the scripts used in the current one).
(Behavior in the outline view when there is a selection remains the same. So if the endpoints of a spline are both selected then all local extrema will be added to that spline, no matter how long it may be).

Reference dependencies and plugin in the html
By default the location of PDF.js assets are automatically determined. However if you place them on alternative locations they may not be found. If so, you can configure these locations.
You may choice to disable use of Web Workers API. This is useful if you want to add pdf.worker.js to your concatinated JavaScript file. However this will have a negative effect on the runtime performance.
To reference the viewer.css file, override the pdf.js-viewer options in your bower.json like this:
| Argument | Possible value | Description |
|---|---|---|
| modal | true false |
A boolean to open the directive in modal mode. |
| customClass | A string that represent a class to add to the directive's container. | |
| theme | dark light |
A string that represent the theme used to render the directive. The default theme is dark |
| hideHeader | true false |
A boolean to enable/disable the header. The default value is false |
| btnClose | true false |
A boolean to enable/disable the close button in the directive. |
| close | true false |
A boolean use to show or not the standard close button. |
| fnClose | A function that you want to run when the close button is clicked. You can pass one or more argument to function: the corresponding parameters must be entered in an array referenced in the options' field fnClosePrm | |
| fnClose | An array of the arguments passed to fnClose function |


array posix_getrlimit ( void )
posix_getrlimit() returns an array of information about the current resource's soft and hard limits. Each resource has an associated soft and hard limit. The soft limit is the value that the kernel enforces for the corresponding resource. The hard limit acts as a ceiling for the soft limit. An unprivileged process may only set its soft limit to a value from 0 to the hard limit, and irreversibly lower its hard limit.
Returns an associative array of elements for each limit that is defined. Each limit has a soft and a hard limit. List of possible limits returned Limit name Limit description

task force
Recommending tasks to web search users
Web search is often performed in the context of some larger underlying task, involving a nontrivial sequence of steps to be completed. A typical example is planning a trip to a city, say, Barcelona. In order to complete her task, the user typically needs to issue a query for booking a flight to Barcelona, another query for booking a hotel, another one to check the things to do in the city. Some of these steps may be already simplified, for example, the interface for booking the hotel might also include suitable offers for booking a flight, or provide guides for visiting points of interest.
Even in those cases, the user has to deal with the cognitive workload of comparing offers, realizing that she might also need to rent a car, aggregating costs from multiple services, remembering that she would like to ask for special hotel amenities, or issuing new searches when exploring alternative dates. Current web search engines are far from supporting task completion. Hence, there is a growing stream of research aimed at making search engines more aware of complex search tasks (i.e., recognizing what task the user is trying to accomplish) and customizing the search experience appropriately.
Our research work aims to recommend specific tasks to users, based on their search queries. An illustrative scenario is depicted in the following mock-up, where an envisaged interface answers the user query “birthday party” by providing a list of recommended tasks.
We introduce the problem of query-based task recommendation, which is cast as a top-N recommendation problem: returning a list of recommended tasks based on a given search query.
Beyond a single input query, we are also interested in the scenario of a set of queries that all share the same underlying task. Such a set is referred to as search mission. Hence, we introduce the problem of mission-based task recommendation. As an example, given a single query “cake recipe,” a highly relevant task to be recommended might be Make a chocolate cake.
Now, assuming that the search mission also contains a second query “cake decorating ideas,” the task Make a birthday cake would also be relevant. Further, if the mission had a third query “birthday invitation cards,” then the recommended tasks could also include the task Throw a birthday party.
We use a dataset, based on WikiHow articles, as our tasks repository where to recommend tasks from. Each article describes a search task that can be accomplished by following a sequence of specific actions or subtasks. Such an article typically contains the following elements: a title, a brief explanation, and a sequence of steps (each made of a main act summarizing the step, and possibly also of a detailed act) corresponding to its subtasks.
If you are interested in more of this, please read Chapter 7 of my thesis Task-Based Support in Search Engines, for the technical details about how we:
- introduce the two research problems, query-based and mission-based task recommendation;
- propose approaches to address these problems;
- build the whole test collection, consisting of:
- a task repository,
- a set of search missions,
- representative best queries for each mission,
- and corresponding human judgements for relevance assessments;
- and report the experimental results of our proposal, as well as provide a detailed feature and query analysis.

by James R. Griffin III at 2023-03-23 17:46:25.We could not get a new replica to work on the existing pdc-discovery-production
collection. We tried deleting the existing replicas and re-creating them in lib-solr-prod4/5/6
to no avail.
Instead we created a new Solr collection called pdc-discovery-production-2
with two replicas and that worked perfectly. We then re-indexed the data by running the reindex rake task with SOLR-URL env pointing to http://lib-solr8-prod.princeton.edu:8983/solr/pdc-discovery-production-2
.
UPDATE on Mar/2023 To create the new collection we do it via the Solr Admin "Add Collection". There is already a config set for pdc-discovery-production
that we use to create the new one.
Once we confirmed the data was reindexed in pdc-discovery-production-2
we deleted the old pdc-discovery-production
collection and created an alias so that the new pdc-discovery-production-2
collection is also known as pdc-discovery-production
, this way the PDC discovery code and configuration does not need to be updated.
Many, many thanks @hectorcorrea! An additional Solr Collection was created (pdc-discovery-production-1
), and the Solr index was repopulated over a terminal session:
deploy@pdc-discovery-prod2:/opt/pdc_discovery/current$ SOLR_URL=http://lib-solr-prod6.princeton.edu:8983/solr/pdc-discovery-production-1/ bundle exec
rake index:research_data
The Solr Collection Alias was also replaced with one which now defaults exclusively for pdc-discovery-production-1
:
deploy@pdc-discovery-prod2:/opt/pdc_discovery/current$ curl "http://lib-solr-prod6.princeton.edu:8983/solr/admin/collections?action=LISTALIASES"
{
"responseHeader":{
"status":0,
"QTime":0},
"aliases":{
"catalog-alma-production":"catalog-alma-production2",
"library-prod":"library-prod1",
"special-collections-prod":"special-collections-prod2",
"dss":"dss-production2",
"catalog-alma-production-rebuild":"catalog-alma-production3",
"lae-prod":"lae-prod3",
"pdc-discovery-production":"pdc-discovery-production-1"},
"properties":{}}
The final task for fully resolving this will be to ensure that pdc-discovery-production-2
. However, it was proposed that this be delayed until tomorrow (when we can be certain that the migration incurred no problems).

TLS Server
Creating a self-signed certificate
Many ways exists to reach the same goal, this is example is based on Linux and OpenSSL and creates not only a Server Certificate, but also a CA Certificate. An existing CA Certificate makes it easier for the Client PC trusts the Certificates as he only need to trust the CA Certificate and all Certificates signed by this CA (your own CA) are automatically trusted. This not only makes it easier for testing purposes but also if you need to create more Certificates
Create the following 3 files:
ca.cnf
- ca certificate configuration
[req]
prompt = no
distinguished_name = req_distinguished_name
[req_distinguished_name]
C = AT
ST = MYSTATE
L = MYLOCALITY
O = MYORGANIZATION
server.cnf
- server certificate configuration
[req]
default_bits = 2048
prompt = no
default_md = sha256
distinguished_name = req_distinguished_name
[req_distinguished_name]
C = AT
ST = MYSTATE
L = MYLOCALITY
O = MYORGANIZATION
CN = SCM20260D
server_v3.ext
- server certificate extension
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names
[alt_names]
DNS.1 = SCM20260D
IP.1 = <IP_ADDRESS>
The following steps produce a ca.crt
(Certificate Authority) you can publish and import in your PC
- edit
ca.cnf
change the values for C, ST, L and O - Generate a CA private key
$ openssl genrsa -out ca_privatekey.pem 2048
- Generate a 10 years valid CA certificate (from Linux Shell)
$ openssl req -new -x509 -days 3650 -nodes -key ca_privatekey.pem -sha256 -out ca.crt -config ca.cnf
The following steps produce 2 files named serverkey.key
and servercert.crt
you need to use in your device
- edit server.cnf change the values for C, ST, L and O change the value of CN, with DNS the FQDN (server.exampledomain.local), NetBIOS Name (SERVER) or IP Address
- edit server_v3.ext change the values in alt_names section, important to have an entry for the CN value from before important to include CN content from step before!
- Create a Certificate Signing Request
$ openssl req -new -nodes -out server.csr -keyout serverkey.key -config server.cnf
- Generate a 1 year valid self signed Server Certificate
$ openssl x509 -req -in server.csr -CA ca.crt -CAkey ca_privatekey.pem -CAcreateserial -out servercert.crt -days 365 -extfile server_v3.ext
Importing the root certificate
Install the CA Certificate in "Current User" Store Location and "Trusted Root Certification Authorities" Certificate store
- Double click on
ca.crt
and clickInstall Certificate..
- Make sure
Current User
is selected.
- Select
Place all certificates in the following store
. ClickBrowse...
and selectTrusted Root Certification Authorities
From this moment your PC will trust all Certificates signed from your CA
Removing a root certificate from a PC
- Either run certmgr.msc or search for cert in Windows 10 Settings and select "Manage user certificates" to open Cert Manager for Current User, not for Local Computer
- Select "Trusted Root Certification Authorities" and "Certificates", on the right side find your certificate based on the values from
ca.cnf
This sample of code uses X509Certificate
. Place the certificate inside the projects Resources
Tip
Add using statement: System.Security.Cryptography.X509Certificates;
byte[] servercert = Resources.GetBytes(Resources.BinaryResources.servercert);
X509Certificate certificate = new X509Certificate(servercert){
PrivateKey = Resources.GetBytes(Resources.BinaryResources.serverkey),
};
This sample of code uses SslStream
Tip
Add using statements: using System.Net.Security & using System.Net.Sockets
Socket socket;
NetworkStream stream;
try{
SslStream sslStream = new SslStream(socket);
sslStream.AuthenticateAsServer(certificate, System.Security.Authentication.SslProtocols.Tls12);
stream = sslStream;
}
catch (InvalidOperationException){
}
stream.Write(byte[]buffer,int offset, int count);
stream.Read(byte[]buffer, int offset, int count);

--- layout: doc title: Documentation ---
This chapter describes what you can do from inside the goals buffer, providing support for these features exists for your proof assistant.
As of Proof General 4.4, this support has existed only for LEGO and proof-by-pointing functionality has been temporarily removed from the interface. If you would like to see subterm activation support for Proof General in another proof assistant, please petition the developers of that proof assistant to provide it!
| 6.1 Goals buffer commands |
When you are developing a proof, the input focus (Emacs cursor) is usually on the script buffer. Therefore Proof General binds some mouse buttons for commands in the goals buffer, to avoid the need to move the cursor between buffers.
The mouse bindings are these:
pg-goals-button-action
proof-undo-and-delete-last-successful-command
pg-identifier-under-mouse-query
Where mouse-1 indicates the left mouse button, and mouse-3
indicates the right hand mouse button. The functions available provide
a way to construct commands automatically (pg-goals-button-action
)
and to inspect identifiers (pg-identifier-under-mouse-query
) as
the Info toolbar button does.
Proof-by-pointing is a cute idea. It lets you automatically construct
parts of a proof by clicking. You can ask the proof assistant to try to
do a step in the proof, based on where you click. If you don’t like the
command which was inserted into the script, you can comment use the
control key with the right button to undo the step and delete it from
your script (proof-undo-and-delete-last-successful-command
).
Proof-by-pointing may construct several commands in one go. These are sent back to the proof assistant altogether and appear as a single step in the proof script. However, if the proof is later replayed (without using PBP), the proof-by-pointing constructions will be considered as separate proof commands, as usual.
The main function for proof-by-pointing is pg-goals-button-action
.
Construct a proof-by-pointing command based on the mouse-click event.
This function should be bound to a mouse button in the Proof General
goals buffer.
The event is used to find the smallest subterm around a point. A position code for the subterm is sent to the proof assistant, to ask it to construct an appropriate proof command. The command which is constructed will be inserted at the end of the locked region in the proof script buffer, and immediately sent back to the proof assistant. If it succeeds, the locked region will be extended to cover the proof-by-pointing command, just as for any proof command the user types by hand.
Proof-by-pointing uses markup describing the term structure of the concrete syntax output by the proof assistant. This markup is useful in itself: it allows you to explore the structure of a term using the mouse (the smallest subexpression that the mouse is over is highlighted), and easily copy subterms from the output to a proof script.
Query the prover about the identifier near mouse click event.

Hello friends,
Our team is excited to announce a new tool in our ecosystem - The Lab!
The Lab is a test runner for Ferret that helps you to test how your scripts retrieve data or validate web UI.
Let’s see how it works!
Get started
The Lab can be installed either by downloading a binary or pulling a Docker image:
$ docker pull montferret/lab
If you are macOS/Linux user, you can install the latest binary with the shell script:
$ curl https://raw.githubusercontent.com/MontFerret/lab/master/install.sh | sudo sh
In this tutorial, we are going to use a local binary.
First run
Let’s create a simple script that retreives GitHub trending projects:
Let’s save it in a file called trending.fql
.
Now we can the query with lab
:
$ lab trending.fql
9:04PM DBG using User-Agent user-agent=
9:04PM INF Passed Duration=1.32741042s File=/Users/ziflex/Work/src/github.com/MontFerret/_scripts/trending.fql Times=1
9:04PM INF Done Duration=1.32741042s Failed=0 Passed=1
lab
has successfully executed the given script! Even though it might not look very impressive, it is pretty useful when you write scripts to test a UI, like this:
Let’s save this query in a file called assertions.fql
and execute it:
$ lab assertion.fql
9:06PM DBG using User-Agent user-agent=
9:06PM INF Passed Duration=415.113954ms File=/Users/ziflex/Work/src/github.com/MontFerret/_scripts/assertion.fql Times=1
9:06PM INF Done Duration=415.113954ms Failed=0 Passed=1
Great! Now we have 2 scripts that we can run together:
$ lab .
9:07PM DBG using User-Agent user-agent=
9:07PM INF Passed Duration=1.402902567s File=/Users/ziflex/Work/src/github.com/MontFerret/_scripts/assertion.fql Times=1
9:07PM DBG using User-Agent user-agent=
9:07PM INF Passed Duration=134.648972ms File=/Users/ziflex/Work/src/github.com/MontFerret/_scripts/trending.fql Times=1
9:07PM INF Done Duration=1.537551539s Failed=0 Passed=2
Suite files
All that good, but why would we bother writing something that can be achieved by Ferret alone?
The answer is suite files.
Till this moment, we’ve used plain FQL files which lab
directly executed using ferret
without possibility to validate correctness of returned data.
Here come suite files:
query:
ref: trending.fql
assert:
text: |
RETURN<EMAIL_ADDRESS>25)
Ok, what’s happening here is that we have decoupled our query from the assertions. lab
executes a query from the query
section and then validates returned data by executing another query from the assert
section.
The @lab
parameter is a built-in parameter that holds runtime information, like query results and cdn
endpoints, which we will discuss later.
Serving static files
One of the features that lab
provides is static files server called cdn
. The cdn
endpoint allows you to serve any static files or web apps during execution of the tests.
Let’s create a plain text file and simple query that will download a it using the cdn
endpoint.
$ mkdir content
$ echo "Hello world" > content/readme.txt
$ touch cdn-example.fql
As you have alredy seen before, we are using the @lab
param to get access to available cdn endpoints.
content
is a directory name that is used for static files.
$ lab --cdn=./content cdn-example.fql
⇨ http server started on [::]:57150
9:10PM INF Passed Duration=13.387547ms File=/Users/ziflex/Work/src/github.com/MontFerret/_scripts/cdn-example.fql Times=1
9:10PM INF Done Duration=13.387547ms Failed=0 Passed=1
In the logs before script execution, we see that lab
launched a web server on port 57150 in order to serve static files.
Parallel execution
By default, lab
executes queries sequentially, but you can make it run in parallel by setting concurrency
parameter to the required level of parallelism:
$ lab --concurrency=10 .
Docker
Aside from binary files, lab
is also distributed as Docker images via GitHub and Docker Hub that have both lab
binaries and headless Chromium
:
$ docker run --rm -v $PWD:/test montferret/lab:1.2.0
Summary
Let’s summarize what we’ve learned.
lab
can be useful to test correctness of your scraping queries by running them and validating their outputs.
Also, lab
can help in testing UI by using the new assertion library.
In some scenarios, it can be used as a batch script runner that can execute your scripts in parallel that will simplify your infrastructure.


This article introduces how to use MOSN to build the Service Mesh development environment based on SOFAMesh framework, and verify some basic capabilities of MOSN, such as routing and load balancing. This article includes the following content:
- Relationship between MOSN and SOFAMesh
- Preparations
- Deploy SOFAMesh with source codes
- Bookinfo experiment
Relationship between MOSN and SOFAMesh
As mentioned in MOSN introduction, MOSN is a Service Mesh data plane agent developed with Golang, and SOFAMesh is a large-scale implementation solution for Service Mesh, which is improved and extended based on Istio. Serving as a critical component of SOFAMesh, MOSN is used to complete data plane forwarding.
The following figure shows the workflow chart of MOSN based on the overall SOFAMesh framework.
Note: Currently, MOSN cannot be directly used in the native Istio.
Preparations
This guide supposes you are using macOS. For other operating systems, you can install the corresponding software.
1. Install HyperKit
Install docker-for-mac, and then install driver.
1.1 Install Docker
Download the Docker software package to install it or run the following command to install it:
$ brew cask install docker
1.2 Install driver
$ curl -LO https://storage.googleapis.com/minikube/releases/latest/docker-machine-driver-hyperkit \
&& chmod +x docker-machine-driver-hyperkit \
&& sudo mv docker-machine-driver-hyperkit /usr/local/bin/ \
&& sudo chown root:wheel /usr/local/bin/docker-machine-driver-hyperkit \
&& sudo chmod u+s /usr/local/bin/docker-machine-driver-hyperkit
2. Install Minikube (or purchase the commercial version of k8s cluster)
It is recommended to use Minikube V0.28 or later, see https://github.com/kubernetes/minikube.
$ brew cask install minikube
3. Start Minikube
Note that Pilot requires at least 2G memory, so you can add resources to Minikube by adding parameters at startup. If your machine has insufficient resources, it is recommended to use the commercial version of the k8s cluster.
$ minikube start --memory=8192 --cpus=4 --kubernetes-version=v1.15.0 --vm-driver=hyperkit
Create Istio namespace
$ kubectl create namespace istio-system
4. Install kubectl command line tool
kubectl is a command line interface used to run commands for k8s cluster. For how to install it, see https://kubernetes.io/docs/tasks/tools/install-kubectl.
$ brew install kubernetes-cli
5. Install Helm
Helm is a package management tool for k8s. For how to install it, see https://docs.helm.sh/using_helm/#installing-helm.
$ brew install kubernetes-helm
Deploy SOFAMesh with source codes
1. Download SOFAMesh source codes
$ git clone git@github.com:sofastack/sofa-mesh.git
2. Use Helm to install SOFAMesh
You should change directory to sofa-mesh source code, and then use helm template to install isito crd and istio
```
$ cd sofa-mesh
$ helm template install/kubernetes/helm/istio-init --name istio-init --namespace istio-system | kubectl apply -f -
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system | kubectl apply -f -
```
Uninstall
```
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system | kubectl delete -f -
$ kubectl delete namespace istio-system
```
3. Verify installation
When the pods in the istio-system namespace are Running, it means SOFAMesh has been successfully deployed. If you just want to run ‘bookinfo’ example, you only need ‘citadel’, ‘pilot’, and ‘sidecar-injector’ are Running.
$ kubectl get pods -n istio-system

BookInfo experiment
BookInfo is a book application like Douban. It contains four basic services.
- Product Page: Homepage, which is developed with Python, shows all book information and calls the Reviews and Details services.
- Reviews: Comment, which is developed with Java, shows book reviews and calls the Ratings service.
- Ratings: Rating service, which is developed with Nodejs.
- Details: Book details, which is developed with Ruby.
1. Deploy BookInfo application and inject it to MOSN
For the specific procedure, see https://istio.io/docs/examples/bookinfo/.
- Inject to MOSN
$ kubectl label namespace default istio-injection=enabled
- Deploy Bookinfo
$ kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
- Verify if the deployment is successful
$ kubectl get services
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE

- Wait till all pods run successfully
$ kubectl get pods

reviews-v3-1813607990-8ch52 2/2 Running 0 6m
2. Access BookInfo service
- Enable gateway mode
$ kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml
$ kubectl get gateway // Check if the gateway runs
NAME AGE
bookinfo-gateway 24m
- Set gateway address
See the details for set gateway address in https://istio.io/docs/tasks/traffic-management/ingress/ingress-control/#determining-the-ingress-ip-and-ports
$ export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="http2")].nodePort}')
$ export SECURE_INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name=="https")].nodePort}')
$ export INGRESS_HOST=$(minikube ip)
$ export GATEWAY_URL=$INGRESS_HOST:$INGRESS_PORT
- Verify if the gateway takes effect
$ curl -o /dev/null -s -w "%{http_code}\n" http://$GATEWAY_URL/productpage //If 200 is output, it means a success
200
- Observe the page status
Visit http://$GATEWAY_URL/productpage. Note that, you need to replace $GATEWAY_URL
with the address you set. Normally, you can see the following BookInfo interface after refreshing the page. There are three versions of Book Reviews. After refreshing, you can see them in turn. To learn why these three versions appear, view the configuration in samples/bookinfo/platform/kube/bookinfo.yaml
.
Interface of version 1
Interface of version 2
Interface of version 3
3. Verify MOSN’s capability of routing by version
- Firstly, create a series of destination rules for BookInfo’s services.
$ kubectl apply -f samples/bookinfo/networking/destination-rule-all.yaml
- Specify reviews service to access v1 only.
$ kubectl apply -f samples/bookinfo/networking/virtual-service-all-v1.yaml
Visit http://$GATEWAY_URL/productpage, and find that the reviews are fixed in the following version 1 page and no longer change.
4. Verify MOSN’s capability of routing by weight
- Allocate 50% traffic respectively to v1 and v3
$ kubectl apply -f samples/bookinfo/networking/virtual-service-reviews-50-v3.yaml
Access http://$GATEWAY_URL/productpage, and find that the probability for v1 and v3 to appear respectively is 1⁄2.
5. Verify MOSN’s capability of routing by specific header
- There is a login entrance in the upper right corner of the BookInfo system. After you log in, the request carries the custom parameter
end-user
of which the value is user name. Mosn supports routing by the value of this header. For example, route the user Jason to the v2 while other users to v1 (both username and password are Jason, why this user can view the corresponding yaml file).
$ kubectl apply -f samples/bookinfo/networking/virtual-service-reviews-test-v2.yaml
When you access http://$GATEWAY_URL/productpage:
Log in with the account of Jason and you will see the v2 interface.
Log in with the account of another user, you are always on v1 interface.

A week after Meursault's arrest, he’s questioned by the magistrate. During the first interrogation, Meursault reveals that he has not hired a lawyer( pg 64). Meursault is taken to see the magistrate. His lawyer isn't present. Due to unforeseen circumstances the magistrate has a question for him, why did Meursault love his mother and why did he pause between the first and second shot (pg 66-67). >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> This chapter is important because this chapter shows that Meursault emotion. And it also shows that Meursault love his mother but why she did not feel anythings when his mother dead.
Meursault is in prison awaiting trial. He dispassionately dislikes it, and decides that, should he get out, this is one phase of his life he probably wouldn't enjoy talking about(pg72). Later Marie visits Meursault in prison wearing nice with no privacy.(pg73) . Marie encourage Meursault you will get out of prison and marie shouted they will be married to each other. But he answered”you think so”.(pg74-75). Meursault's biggest problem in the first few months of prison is that he had the thoughts of a free man. Often he'd suddenly experience the urge to walk on the beach and swim in the water. Or he would think of women. Never Marie specifically, but just any and all women.(pg76-77). As days goes on and Meursault is trying to kill time for the trial. He looked at a tinplate looking at his reflection and started to backtracks all had happened during prison.(pg81) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> This chapter is important because it shows that meursault had changed during difficult times, he show a different side of him during this time.
By the beginning of summer, trial has been set for June, in the Court of Assizes. (pg82) Also Meursault's attorney tells him that it wouldn't last more than two or three days because a more interesting case is coming up after his trial. (pg82) Then later on he was taken out put into the van, and driven to the prison where he had something to eat.Then after a very short time the court started again. (pg88) Raymond is the last witness. He blurts out that Meursault is innocent. The judge reprimands him, as he's supposed to be calmly relating facts, not babbling on about his opinion. (pg95 and 96) Lastly ,Meursault reflects on the town he once loved and moments when he was once happy. (pg 97) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> This event is important because this shows how Meursault been through his life after the shooting event. It shows his life collapse into pieces.


set cachesf num
Use this command to change the scale factor for setting the default cache size (in bytes), which is calculated according to this formula:
X grid size * Ygrid size * 8 * cachesf
The default cache scale factor is 1.
This command is available with GrADS version 2.0.a8 or later.
The cache size is only relevant when reading HDF5 and NetCDF4 data types.
Cache size is set on a per-file basis; the cache size will be different for each file opened in GrADS. After a file is opened, a new cache is allocated for each variable that gets displayed in the file. Be careful
Current value of the cache size may be discovered with the query cache
command.
Please see the documentation on compression for more details.


| qcache {qs} | R Documentation |
Helper function for caching objects for long running tasks
qcache(expr, name, envir=parent.frame(), cache_dir=".cache", clear=FALSE, prompt=TRUE, qsave_params=list(), qread_params=list())
expr |
The expression to evaluate |
name |
The cached expression name (see details) |
envir |
The environment to evaluate 'expr' |
cache_dir |
The directory to store cached files in |
clear |
Set to 'TRUE' to clear the cache (see details) |
prompt |
Whether to prompt before clearing |
qsave_params |
Parameters passed to 'qsave' |
qread_params |
Parameters passed to 'qread' |
This is a (very) simple helper function to cache results of long running calculations. There are other packages specializing in caching data that are more feature complete.
The evaluated expression is saved with 'qsave' in <cache_dir>/<name>.qs. If the file already exists instead the expression is not evaluated and the cached result is read using 'qread' and returned.
To clear a cached result, you can manually delete the associated 'qs' file, or you can call 'qcache' with 'clear=TRUE'. If 'prompt' is also 'TRUE' a prompt will be given asking you to confirm deletion. If 'name' is not specified, all cached results in 'cache_dir' will be removed.
cache_dir <- tempdir() a <- 1 b <- 5 # not cached result <- qcache({a + b}, name="aplusb", cache_dir = cache_dir, qsave_params = list(preset="fast")) # cached result <- qcache({a + b}, name="aplusb", cache_dir = cache_dir, qsave_params = list(preset="fast")) # clear cached result qcache(name="aplusb", clear=TRUE, prompt=FALSE, cache_dir = cache_dir)

Google antitrust probe to expand into Android: CNBC
The 50 attorneys general investigating advertising practices at Alphabet Inc's Google are planning to expand their antitrust probe into the unit's flagship Android business, CNBC reported on Thursday, citing people familiar with the matter.
REUTERS: The 50 attorneys general investigating advertising practices at Alphabet Inc's Google are planning to expand their antitrust probe into the unit's flagship Android business, CNBC reported on Thursday, citing people familiar with the matter.
Google did not immediately respond to a Reuters request for comment. (https://cnb.cx/376FVQo)
The Google probe is being led by the Texas attorney general's office and is known to be focused on its search and digital advertising businesses.
The Alphabet unit also faces two other major inquiries — a U.S. Justice Department investigation and a probe by the House of Representatives Judiciary Committee — both of which have broad reviews of the big internet companies underway.
Last year, Google was fined 4.34 billion euros by the European Commission, saying the tech giant gave itself an unfair advantage by pre-installing its Chrome browser and Google search app on Android smartphones and notebooks.

My name is Samuel Tober, and I am a Msc. student in computer science at the Royal Institute of Technology (KTH) in Stockholm, Sweden. For a living, I work as a data analyst within insurance, mainly focusing on risk premium modelling, machine learning and data engineering. I am passionate about data science, mathematics, and technology in general. I spend most of my spare time climbing and playing the piano (not at the same time though!). I use this website to document my projects, as a set of tutorials on various subjects that I find interesting, and as my personal journal. My goal is to not always write about technology related matters, but also to touch on other topics. I hope you find something of value!


| cols_label {gt} | R Documentation |
Column labels can be modified from their default values (the names of the
columns from the input table data). When you create a gt table object
using gt()
, column names effectively become the column labels. While this
serves as a good first approximation, column names aren't often appealing as
column labels in a gt output table. The cols_label()
function
provides the flexibility to relabel one or more columns and we even have the
option to use the md()
or html()
helper functions for rendering column
labels from Markdown or using HTML.
cols_label(data, ..., .list = list2(...))
data |
A table object that is created using the |
... |
One or more named arguments of column names from the input |
.list |
Allows for the use of a list as an input alternative to |
It's important to note that while columns can be freely relabeled, we
continue to refer to columns by their original column names. Column names in
a tibble or data frame must be unique whereas column labels in gt have
no requirement for uniqueness (which is useful for labeling columns as, say,
measurement units that may be repeated several times—usually under
different spanner column labels). Thus, we can still easily distinguish
between columns in other gt function calls (e.g., in all of the
fmt*()
functions) even though we may lose distinguishability in column
labels once they have been relabeled.

I have been very busy, but that’s no excuse. I’m lowering the bar for things that deserve a blog post. This particular post will feature things I’ve been thinking about and doing.
Things that have happened
My sister and her kids came to visit a couple of weeks ago. It was a fun visit! Everything was made more complicated by COVID, but it all turned out OK.
I crashed my mountain bike on Sunday, which was not fun. It was one of the higher speed crashes I’ve had. My front tire washed out on a corner and I slid quite a ways, scraping up my knee (even though I was wearing knee pads) and somehow hurting my pinky, which has been the most debilitating result of the crash.
I received a promotion at work. I am now leading the Infrastructure squad at Seeq. This is exciting for me, since I enjoy working on cloud-based infrastructure and development tools, which is what the team is responsible for.
Books I’ve been reading
I finished Prey by Michael Crichton. I plan to write up a book review of it soon.
I also finished reading Being Mortal, which was a superb book. I’ll have to refer to it again the next time I’m faced with the mortality of myself or someone I love. I should also write up a review of that book.
I have been working on another excellent book, which I hope to finish soon, Seeking Allah, Finding Jesus by Nabeel Qureshi. I’ll post more thoughts when I’ve finished it.
Projects I’ve been working on
I have been plugging away at editing a YouTube video of a morning ride I did in Reno. It’s been so long since I’ve edited any video that it’s proving a bit time consuming. I hope to have it finished and posted soon.
Tralina and I have also been getting more serious about cooking. Tralina purchased a Shun santoku knife, which is very nice. I will be getting a chef’s knife soon. I have been browsing Forks Over Knives quite excitedly, looking for recipes that look good. Today I cooked Mediterranean Vegetable Spaghetti, which was not very good and definitely did not meet Tralina’s approval. I also made a “No-Tuna” Salad, which Tralina did approve. She said that it reminded her of the tuna salad that her mom used to make before I even mentioned that it was supposed to be a tuna salad substitute. So I call that a win!
What’s next
It might be nice to post regular updates similar to what Sacha Chua does on her excellent blog. If I decide to do that, I’ll probably want to come up with a consistent format.


Bilbo Baggins was born on September 22 by Shire Reckoning, in the year 2890 of the Third Age, the son of Bungo Baggins and Belladonna Took. He was a grandson of the Old Took. Gandalf suggested Bilbo Baggins to be hired by Thorin and Company to be their burglar in the Quest of Erebor, and later fought in the Battle of the Five Armies. Bilbo was also one of the bearers of the One Ring, and the first to voluntarily give it up, although with some difficulty. He wrote many of his adventures in a book he called There and Back Again. Bilbo adopted Frodo Baggins as his nephew after his parents, Drogo Baggins and Primula Brandybuck, drowned in the Brandywine River.

Injury Blow For Liverpool As Key Midfielder Is Ruled Out Until 2020
by Donatus AnichukwuezeLiverpool have revealed that Fabinho suffered ankle ligament damage against Napoli, which will rule the Brazil international out of action until 2020.
The news comes as a huge blow to Jurgen Klopp’s plans, with the South American having become a key component in the Reds’ Premier League title-chasing side.
With a packed schedule ahead of them, Liverpool would have been hoping to avoid any untimely setbacks, however, Fabinho will not be seen again for the remainder of the calendar year.
That means that the 26-year-old will sit out important domestic fixtures in an ongoing bid for English top-flight glory, while also missing the Reds’ quest to claim the FIFA Club World Cup crown.
No timescale has been put on his recovery, but those at Anfield are preparing themselves to be without one of the finest holding midfielders in the business for a prolonged period of time.
A statement released on the club’s official website read: “Liverpool can confirm Fabinho suffered ankle ligament damage during the Champions League encounter with Napoli in midweek.
“The midfielder needed to be substituted after 18 minutes of the 1-1 draw at Anfield on Wednesday night after falling awkwardly during a challenge.
“Further assessment on the injury has discovered Fabinho will be out of action until the New Year.
“The Brazilian will begin a rehabilitation programme with the Reds’ medical team at Melwood as he works his way back to full fitness.”
Klopp admitted after witnessing Fabinho being forced from the field against Napoli that losing the Brazilian would be “massive” for Liverpool.
Former Reds star Harry Kewell has also been left cursing the club’s luck after seeing a man who has made rapid progress over recent months ruled out for the foreseeable future.
He told Sky Sports: “It is a huge loss, he’s been the sponge.
“He’s soaking everything up. When he receives the ball, he passes it forward – which many holding midfielders don’t do, that first pass forward to put your team on the attack.
“It’s a big loss, but I’m confident in the squad that there are plenty to fill in.”
The first game in which Liverpool will need to find cover for Fabinho is set to see them play host to Brighton on Saturday.

Blackpool striker Armand Gnanduillet fights to be fit for FA Cup tie with Maidstone United
Simon Grayson has revealed that Armand Gnanduillet faces a race against the clock to be fit in time for Blackpool’s FA Cup tie against Maidstone United.
by Matt ScraftonThe striker, who is suffering with a thigh injury he picked up in the recent win against AFC Wimbledon, missed his second game running in midweek.
The Frenchman could be back in time for Sunday’s second round tie at Bloomfield Road, but Grayson was unable to provide any assurances.
“He was never going to be fit (for Wednesday’s EFL Trophy game against Scunthorpe United), although his thigh is making progress,” the Pool boss told The Gazette.
“We’ll see where he is for the weekend but this game was never going to be a consideration.
“If he was fit he’d have been around it but he wasn’t. He wasn’t being rested or anything like that.
“We’ll see where he is for the weekend.”
The Seasiders will be hoping to avoid an embarrassing cup exit to a side that ply their trade in the National League South.
Grayson will be keen to see a reaction from his side after publicly blasting the players that featured in the midweek defeat in the EFL Trophy.
That loss brought an end to Pool’s seven-game unbeaten run in all competitions.
“Players have played themselves out of contention,” Grayson said.
“You pick a team at the weekend that obviously wants to win the game and I want to see a reaction the next time we’re in training.
“I want to see them be professional, play with a purpose, training with an edge, because we had no edge to us on Wednesday.
“Over the last few weeks when we’ve had good results we played with an edge both with and without the ball. We didn’t have it this time.
“We wanted to win the game and carry on the momentum and try and keep progressing and win as many matches as is possible.
“I don’t mind losing matches if you lose it with a purpose in terms of working hard, closing down and trying to outrun the opposition. But we didn’t do that.”


In a directed graph (assume no cycles), each node is assigned an uppercase letter. We define a path's value as the number of the most-frequently-occurring letter along that path. For example, if a path in the graph goes through "ABACA", the value of the path is 3, since there are 3 occurrences of 'A' on the path.
Given a graph with n
nodes and m
directed edges, return the largest value path of the graph. If the largest value is infinite, then return null.
The graph is represented with a string and an edge list. The i
-th character represents the uppercase letter of the i
-th node. Each tuple in the edge list (i, j)
means there is a directed edge from the i
-th node to the j
-th node. Self-edges are possible, as well as multi-edges.
For example, the following input graph:
The output will be 4, since A will have the maximum frequency out of all the letters which will occur in the path : A -> B -> A -> C -> A
Let's try to simplify the problem.
For each path of the graph, the value is equal to the frequency of the most frequently occurring letter. Out of all the possible paths, we have to find the maximum value.
Approach 1:
We can do a classic DFS over the graph and go through all the paths possible.
For each path, we keep track of the frequency of each letter.
Out all such paths and their letter frequency count, we find the maximum frequency.
More Efficient Approach:
We can easily notice that if a node has mode than 1 incoming edge, then we will end up doing many repeated computations.
We can cache the result for each of the node as a map that contains the frequency count for that node.
If we ever encounter that node again, we'll use the value from the cache.
The above approach can be implemented as follows:
