Klopp reveals where Brighton surpass Liverpool; tips trio to replace Fabinho
Jurgen Klopp says Liverpool must find a way to deal with the absence of Fabinho after the midfielder’s injury.
However, Klopp insists his squad will be able to find a solution – with three players tipped to fill his boots.
“It’s absolute bad news. I have nothing good to say about that. I’m not sure how long it’ll take but it’s looking like he won’t be involved in the Christmas fixtures.
“It was my main problem after the game but we have solutions and replacements for him.
“We can play without him. We are not the only team with injury players.
“We have to deal with it and we will.
“Naby [Keita] is OK. No more injuries from Napoli other than Fab.
“It is an opportunity for someone, of course. Hendo [Jordan Henderson], Gini [Wijnaldum] and [Adam] Lallana have all played it. We can system too. Losing a player of Fab’s quality is a blow but we are not the only team with injuries.
“The three players I’ve mentioned have played there. They bring a different quality.
“Gini was brilliant against Napoli. Hendo has played there really, really good. We just have to make it work.”
While he may have a headache over who to play in midfield, he has no similar struggles about working out where the goals will come from, with several members of the team sharing scoring duties this season. It’s something Klopp is pleased to see – even if he thinks there is room for improvement.
“It’s not too long we were talking about how we rely on our front three. I couldn’t care less who scores, I’m just really happy when the ball is in the net. Of course, it is good. Makes us a bit more unpredictable. We could have scored more.
While Liverpool are on a rampant run of form, Klopp is under no illusion about the size of the task at hand to beat Brighton at the weekend.
“[Graham] Potter is doing a fantastic job at Brighton. It will be a tough one.
“This is just the next game. Everyone has three games a week coming up but they have had time to prepare. We had an intense game against Napoli.
“We’re not the most intense team in the league, other teams run more than us. Brighton run much more overall.
“There are games where you have to be very intense, in others we have to control the game more. Most important thing is we don’t feel the numbers.
“We don’t think about 12 wins in 13. We are only 100% about next opponent.
“In this moment, we want to play the best football we can play, and we have to against Brighton. They are not only brave and football playing, they are organised a while. They are always in the game.”

Neuroplasticity and Growth Mindset
Learn about neuroplasticity and growth mindset was a watershed in my journey as a student. Now I am sure that our intelligence and talents can be developed over time. There is a ton of research on the topic already.
However, I must admit that I Had a Fixed Mindset and looking back now I think about how my life could be different if I knew about that before.
Comparing how I was then, to how I am now.
Fixed Mindset
Growth Mindset
I have a negative inner voice that acts against a growth mindset. Now I am Trying to flip thoughts such as ‘I can’t do this’, to ‘I can do this if I keep practicing’ to nurture a growth mindset.
I am learning how hard work, good strategies, and good use of resources lead to better learning.
“The passion for stretching yourself and sticking to it, even (or especially) when it’s not going well, is the hallmark of the growth mindset.”


Background
Apple’s Mail app for iOS seems to treat a single email address as a single character once entered. When you try to edit the text, the whole email is selected.
In an attempt to mimic the email entry behaviour of the Mail app, I came upon an issue when rendering instances of NSTextAttachment
inside a UITextView
.
The Problem
To accomplish this, I attempted to take snapshots of the entered text, and render it as a text attachment inline with any additional text (I might write another post about the data source behaviour another time).
The technique worked very well, except I found my text baseline was being thrown around a bit.
This had me stumped for a while. The UIImage
that I had generated for the NSTextAttachment
was simply a UILabel
rendered offscreen, and then sized to fit. Given that all my font sizes and string attributes matched up, there should not be any reason for the baselines to not line up perfectly.
I set a background colour on the label to investigate:
Aha! It looks like by default, the UITextView
renders instances of NSTextAttachment
on the baseline, extending upwards. This means the larger the image, the further down my baseline of the following text will be pushed.
You can see the snapshotted UILabel
has space at the bottom for it’s descenders, so we don’t want it rendering on the baseline.
The Solution
After spending far too much time delving into various TextKit classes, I came up with a fairly straightforward solution.
I started checking out the NSLayoutManager
class, as that seemed to control how glyphs and characters are positioned in a text container. However it turns out that the NSTextAttachment
class already has a method returning it’s bounds:
-attachmentBoundsForTextContainer:proposedLineFragment:glyphPosition:characterIndex:
So, I made a simple subclass of NSTextAttachment
which exposes a property for adjusting the y-offset of the attachment bounds.
@interface InlineTextAttachment : NSTextAttachment
@property CGFloat fontDescender;
@end
@implementation InlineTextAttachment
- (CGRect)attachmentBoundsForTextContainer:(NSTextContainer *)textContainer proposedLineFragment:(CGRect)lineFrag glyphPosition:(CGPoint)position characterIndex:(NSUInteger)charIndex {
CGRect superRect = [super attachmentBoundsForTextContainer:textContainer proposedLineFragment:lineFrag glyphPosition:position characterIndex:charIndex];
superRect.origin.y = self.fontDescender;
return superRect;
}
@end
Using this subclass now, I can grab the descender value from the font I’m using in my attributed string.
UIImage *labelImage = [label snapshotImageAfterScreenUpdates:NO];
InlineTextAttachment *attachment = [[InlineTextAttachment alloc] initWithData:nil ofType:nil];
UIFont *font = [aString attribute:NSFontAttributeName atIndex:0 effectiveRange:NULL];
attachment.fontDescender = font.descender;
attachment.image = labelImage;
And bingo! The descender height was exactly the offset I needed to get all my NSTextAttachment
instances to line up nicely with my existing text.

Project Influence
Influenced by the Cherno Alpha Jaeger design by Russia in Guillermo Del Toro's seminal Pacific Rim in 2013. Russian like designs call for a design that is rugged, massive in size and packs a lot of power. Powered by a 11.1V battery with 1500mAh capacity and two 200 Steps/Rev and 3.6 A/phase stepper motors on a 3D printed chassis, I entered the 2018 IEEE Robotics Olympiad held at Brown University with my Micromouse version of Cherno Alpha
Implementation
The chasis, designed by Anthony Xu (Union College), was 3D printed.
Wall sensing are povided through usual IR sensors. One at the front and two on the sides. Motors are two stepper motors, which are prices and thus there was no need for a PID controller. Two side sensors are also used to realign the robot as it goes.
Two motors are controlled by two stepper Sparkfun motor drivers and received signals from a Arduino UNO microcontroller. They are first wired directly, and soldered onto a protoboard for a cleaner version.
Final Version
Algorithm
Modified Floodfill algorithm is documented here.
Voice-controlled using Google Assistant
Google AIY Voice Kit voice 1 is used for this project. It is powered by a Raspberry Pi 3. My code uses Google Cloud Speech and Google Assistant python API. It can behave as an usual Google Assistant with hot word detection: OK Google or Hey Google.
My Bluetooth Module enables the robot to be connected remotely. Locals commands are added so that the Google Assistant can find nearby Bluetooth devices and connect to the robot. It can move the robot forward, turn left, right, 180 and reset to origin. It can also set the robot in autonomous mode, which will enable floodfill algorithm.

MEN LIE A Film Review by James Berardinelli Copyright 1994 James Berardinelli
Rating (0 to 10): 5.2
Date Released: (late) Summer 1994 Running Length: 1:26 Rated: R (Language, mature themes, sexual situations)
Starring: Michael DeLuca, Ellia Thompson, Frank Vincent, Victor Argo Director: John Gallagher Screenplay: John Gallagher Distribution undetermined
As might be guessed from the title, this is not a movie that takes an optimistic view on the basic honesty of men in relationships. What might have been called "man bashing" had it been penned by a woman will likely be termed "insightful" and "honest" in this instance, since writer/director John Gallagher is a man.
MEN LIE follows the relationship of Scott (Michael DeLuca in his screen debut) and Jill (Ellia Thompson) through rocky times. Scott is one of those compulsive womanizers who goes to a bar or dance club every night to pick up someone new. At any given time, he has at least one fling going on outside of his long-term relationship. Jill, on the other hand, is resolutely faithful, and convinced that the same is true of her boyfriend. When one of her friends tries to hint at Scott's infidelity, Jill won't listen. Of course, no matter how long she tries to ignore the truth, it's obvious that eventually something is going to happen that Scott won't be able to pass off as an "optical illusion."
Give John Gallagher credit for adding a new spin to an old, old theme. Instead of routinely telling Scott and Jill's story, he inter- sperses their scenes with a number of quirky comments and "interviews" with people-on-the-street types - the modern-day equivalent of a Greek chorus. These feature, among others, Aida Turturro (of ANGIE) as a man-hating woman who wears a hat that declares "Men Lie", Cathy (daughter of Martin) Scorsese and Catherine (mother of Martin) Scorsese arguing about men, and Michael Imperioli (Spider in GOODFELLAS) as a "sex surrogate" who defends his infidelities on the grounds that he's acting in the best interests of his "patients." While many of these sequences contain obvious cliches, they are presented in an engaging, amusing manner. Unfortunately, the primary plot doesn't have the same distinction.
The autopsy of Scott and Jill's relationship is stale, trite, and often unconvincing. If the ultimate aim of this portion of the movie is to get across the "men can be pigs" point, it succeeds, but beyond that, there isn't much here. Both characters are relatively shallow, and the stiff acting of the two leads doesn't help. Not only wasn't I convinced that these were real people, but I didn't much care what happened to them.
Stealing scenes left and right is veteran screen actor Frank Vincent (a Martin Scorsese alum, with GOODFELLAS and RAGING BULL among his numerous credits). Vincent is one of the few consistently good performers, and the comic edge that he brings to Uncle Frank helps defuse the growing sense of tedium. Of course, Frank is just a stereotype, but that doesn't negate the humor.
Writer/director John Gallagher came to this project with the idea of putting together a movie that takes a lighthearted-yet-realistic look at male/female relationships. Given the constraints of a low budget and an 11-day shooting schedule, the result is perhaps better than one might reasonably expect. There are moments when this small, independent production sparkles, but these are sandwiched between scenes that offer little in the way of freshness or creativity. And, after all, does it really take eighty-six minutes to tell us something that's evident from the start - that men lie?

Ansible Basics
NAME HERE, TITLE HERE
COMPANY HERE
WHAT YOU WILL LEARN
Ansible is capable of handling many powerful automation tasks with the flexibility to adapt to many environments and workflows. With Ansible, users can very quickly get up and running to do real work.
In this presentation, we will cover:
What is Ansible
How Ansible Works
Ad-Hoc Commands
Playbook Basics
Reuse and Redistribution of Ansible Content with Roles
Ansible Tower
WHAT IS ANSIBLE AUTOMATION?
The Ansible project is an open source community sponsored by Red Hat. It’s also a simple automation language that perfectly describes IT application environments in Ansible Playbooks .
Ansible Engine is a supported product built from the Ansible community project.
Ansible Tower is an enterprise framework for controlling, securing, managing and extending your Ansible automation (community or engine) with a UI and RESTful API .
The Ansible Project is open source and sponsored by Red Hat.
Ansible Engine is a supported product built from the Ansible community project, and Ansible Tower is the framework for the automation that Ansible Engine does.
There’s also an open-source version of Tower which is the AWX project, and it’s associated with the Ansible GitHub.
WHY ANSIBLE?
So why should you think about using Ansible and what sets it apart?
First off, Ansible is simple: we expect that your user base is going to be mixed with people of all skill levels and because of that we wanted to make it incredibly easy to get started. The language playbooks are written in is YAML, which is very easy-to-read for humans, and those playbooks work consistently across many environments
It’s also extremely powerful in how many nodes we can spin up and manage at any given time, which is largely due to the fact that Ansible is agentless. There are no agents to keep up to date and the requirements are minimal.
THE ANSIBLE WAY
CROSS PLATFORM – Linux, Windows, UNIX
Agentless support for all major OS variants, physical, virtual, cloud and network.
HUMAN READABLE – YAML
Perfectly describe and document every aspect of your application environment
PERFECT DESCRIPTION OF APPLICATION
Every change can be made by playbooks, ensuring everyone is on the same page.
VERSION CONTROLLED
Playbooks are plain-text. Treat them like code in your existing version control.
DYNAMIC INVENTORIES
Capture all the servers 100% of the time, regardless of infrastructure, location, etc.
ORCHESTRATION THAT PLAYS WELL WITH OTHERS – HP SA, Puppet, Jenkins, RHNSS, etc.
Homogenize existing environments by leveraging current toolsets and update mechanisms.
In addition, that agentless support isn’t just Linux exclusive.
This also applies to Windows machines, networking devices, and of course both physical and cloud servers, as well as static or dynamic inventory.
Also, one of the main selling points of Ansible is that we work well with existing toolkits.
Sometimes people don’t know where to start; I’d advise you to pick a pain point in your environment to focus on, something small that you can leverage Ansible for and see how that feels, because you can always homogenize over time.
BATTERIES INCLUDED
Ansible comes bundled with hundreds of modules for a wide variety of automation tasks:
cloud
containers
database
files
messaging
monitoring
network
notifications
packaging
source control
system
testing
utilities
web infrastructure
Installing Ansible nets you a TON of modules that range in type from the popular cloud modules to packaging and database modules.
The list you see here are some of the “high profile” modules, but there are lots more that aren’t listed.
COMMUNITY
THE MOST POPULAR OPEN-SOURCE AUTOMATION COMMUNITY ON GITHUB
34,000+ stars & 13,500+ forks on GitHub
4000+ GitHub Contributors
Over 2000 modules shipped with Ansible
New contributors added every day
1400+ users on IRC channel
World-wide meetups taking place every week
Ansible Galaxy: over 9,000 contributors and 18,000 roles
500,000+ downloads a month
AnsibleFests, Ansible Automates, and other global events
ANSIBLE: COMPLETE AUTOMATION
One of the other bullet points that we highlight around Ansible is that it’s the complete package.
So it’s not just configuration management; it’s also orchestration, app-deployment and provisioning as well.
Looking at this graphic here , you can see that there are tools that definitely perform one or more of these use cases, but can’t do them all and that’s really one of the big strengths of Ansible.
Some users like to refer to it as “Automation Glue”.
WHAT CAN I DO WITH ANSIBLE?
Automate the deployment and management of your entire IT footprint.
On this slide, you can see the different use cases for how to manage and automate your machines.
(some examples are: security and compliance, orchestration, creating new VMs, creating a CI/CD pipeline) - all of these things can be done with Ansible.
INSTALLING ANSIBLE
# the most common and preferred way of installation
$ pip install ansible
# install the epel-release RPM if needed on CentOS, RHEL, or Scientific Linux
$ sudo yum install ansible
# you will need the PPA repo configured
$ sudo apt-get install ansible
There are many ways to install Ansible, including making your own rpm package, running from source, or you can just use a package manager. As you can see, the examples below are using pip, yum, and apt.
The yum and apt installations require additional steps so if you prefer using a single command, then you can install with pip.
1 - Most common and preferred way (unless your Python is set up weird)
2 - If you’re running a RHEL or CentOS type of machine, install epel-release and grab the package from there
3- Ubuntu/Debian flavor OS
If anything stumps you, it’s always helpful to take a look at the Ansible Installation documentation for more information.
HOW ANSIBLE WORKS
Once you have Ansible installed, you’re going to need to become acquainted with the key components of how Ansible works.
The graphic on this slide shows the relationship between all the main pieces of Ansible, starting with the user who writes an Ansible playbook.
MODULES
Modules are bits of code transferred to the target system and executed to satisfy the task declaration.
apt/yum
copy
file
get_url
git
ping
debug
service
synchronize
template
uri
user
wait_for
assert
We talked a bit about modules in the previous couple slides, but I did want to point out a list of some commonly used modules that you may see out in example repos, blog posts, etc. a fair amount.
Typically, you're going to see a lot of package management modules being used, lots of file modules like copy and file, but as mentioned previously, there are tons more as well.
MODULES
https://docs.ansible.com/ansible/latest/modules/modules_by_category.html
You can check out all of them by looking at the exhaustive module index on docs.ansible.com.
They’re broken down by category, so you can more easily find what you need.
I would highly recommend bookmarking this page!
MODULES: RUN COMMANDS
If Ansible doesn’t have a module that suits your needs there are the “run command” modules:
command: Takes the command and executes it. The most secure and predictable.
shell: Executes through a shell like /bin/sh so you can use pipes etc. Be careful.
script: Runs a local script on a remote node after transferring it.
raw: Executes a command without going through the Ansible module subsystem.
NOTE: Unlike standard modules, run commands have no concept of desired state and should only be used as a last resort
On this slide we’re gonna discuss the command and shell modules which are super useful because you can execute commands with them on your remote nodes.
The only big difference is that the command is not processed through the shell so redirect options and certain variables won’t work.
If you need those, just use the shell module instead.
The command modules let you run networking commands with Ansible, the same way a network engineer would type them on the command line.
If you have something that’s not a core module or you haven't written a custom one, you can utilize the script module.
For example, if you want to push out a homegrown script, you can do that here.
We also have the raw module, which issues a pure SSH command and bypasses the python module mechanism.
This is handy if you’re talking to a machine that doesn’t have python (for example, a server that’s running Windows!).
AD-HOC COMMANDS
# check all my inventory hosts are ready to be managed by Ansible
$ ansible all -m ping
# run the uptime command on all hosts in the web group
$ ansible web -m command -a “uptime”
# collect and display the discovered for the localhost
$ ansible localhost -m setup
We’re going to transition right into ad-hoc commands from the commands modules because often times, you utilize command/shell to issue one-off commands to your hosts.
This is essentially what ad-hoc commands are; just quick checks on your servers that you don’t want to preserve in an Ansible playbook.
The examples here are pretty typical.
Our first example is just checking whether we have connectivity with the host by issuing the ping command (I do this all the time to make sure everything is responding).
In the second example here, you can see the command to check the uptime on the two servers in my web group using the command module.
And lastly, the third example is gathering facts about our local machine which would yield the information that you can use for conditionals and variables and whatnot.
[a bit of the output is shown on next slide]
SIDEBAR: DISCOVERED FACTS
$ ansible localhost -m setup
localhost | success >> {
"ansible_facts": {
"ansible_default_ipv4": {
"address": "<IP_ADDRESS>",
"alias": "wlan0",
"gateway": "<IP_ADDRESS>",
"interface": "wlan0",
"macaddress": "c4:85:08:3b:a9:16",
"mtu": 1500,
"netmask": "<IP_ADDRESS>",
"network": "<IP_ADDRESS>",
"type": "ether"
},
INVENTORY
Inventory is a collection of hosts (nodes) against which Ansible can work with.
Hosts
Groups
Inventory-specific data (variables)
Static or dynamic sources
Ad-hoc commands and modules always come back to the inventory we’re managing. Inventory consists of hosts, groups, inventory specific data, and whether it’s static or dynamic sources. Note that “hosts” has been expanded overtime to include network devices, containers and virtually anything else that is network-addressable.
STATIC INVENTORY EXAMPLE
<IP_ADDRESS>
<IP_ADDRESS>
<IP_ADDRESS>
<IP_ADDRESS>
<IP_ADDRESS>
This is a free-form static inventory listed by IP address. If I clean that up a bit, I get...
STATIC INVENTORY EXAMPLE
[control]
control ansible_host=<IP_ADDRESS>
[web]
node-1 ansible_host=<IP_ADDRESS>
node-2 ansible_host=<IP_ADDRESS>
node-3 ansible_host=<IP_ADDRESS>
[haproxy]
haproxy ansible_host=<IP_ADDRESS>
[all:vars]
ansible_user=vagrant
ansible_ssh_private_key_file=~/.vagrant.d/insecure_private_key
...a host file that’s separated into groups (which in this example is control, web, and haproxy).
We also have some inventory-specific data where we’re defining ansible_host for each of these different nodes, and we’ve got a vars section defined for all the hosts where we’re setting the connecting user.
There’s also a path to the private key file we’re using for authentication.
STATIC INVENTORY EXAMPLE IN YAML
all:
vars:
ansible_user: vagrant
ansible_ssh_private_key_file: ~/.vagrant.d/insecure_private_key
children:
web:
hosts:
node-1:
ansible_host: <IP_ADDRESS>
node-2:
ansible_host: <IP_ADDRESS>
node-3:
ansible_host: <IP_ADDRESS>
This is a similar example of the same hosts file in YAML format which is a new option as of version 2.4.
This provides some flexibility in regards to the format you might find easier to work with.
VARIABLES
Ansible can work with metadata from various sources and manage their context in the form of variables.
Command line parameters
Plays and tasks
Files
Inventory
Discovered facts
Roles
To go into a little more detail, variables in Ansible are used to account for differences between servers.
By using variables, I have the ability to keep a nice layer of abstraction in my playbook and define my variables as needed in various host or group vars files.
These could be for things like facts or file paths or package versions.
VARIABLE PRECEDENCE
The order in which the same variable from different sources will override each other:
Extra vars
Set_facts/Registered vars
Include_vars
Include_params
Role params
Task vars (only for the task)
Block vars (only for tasks in the block)
Role vars
Play vars_files
Play vars_prompt
Play vars
Host facts
Playbook host_vars
Inventory host_vars
Inventory file/script host vars
Playbook group_vars
Inventory group_vars
Playbook group_vars/all
Inventory group_vars/all
Inventory file or script group vars
Role defaults
This brings up a good time to talk about variable precedence, which is basically the order in which the same variables will override each other.
The latest version has 21 levels of variable precedence wherein extra_vars will always take precedence and role_defaults will get overwritten by all of these other var types.
TASKS
Tasks are the application of a module to perform a specific unit of work.
file: A directory should exist
yum: A package should be installed
service: A service should be running
template: Render a configuration file from a template
get_url: Fetch an archive file from a URL
git: Clone a source code repository
Just to recap, so far we’ve talked about acting against inventory with modules, but those modules are going to be contained in things called tasks.
These are simple and declarative, because we’re telling the module to do something specific like (give examples from slide of things the modules will do within the tasks).
EXAMPLE TASKS IN A PLAY
tasks:
- name: add cache in directory
file:
path: /opt/cache
state: directory
- name: install nginx
yum:
name: nginx
state: latest
- name: restart nginx
service:
name: nginx
state: restarted
In this example, the first task is called “add cache in directory”.
Note that you can name it anything you'd like.
Here we're going to call the file module and give it a couple of options.
Our path is going to be opt/cache and the state is directory, meaning we're going to create the directory opt/cache.
HANDLER TASKS
Handlers are special tasks that run at the end of a play if notified by another task.
Normal tasks run sequentially, handler tasks run on notification.
Handlers may be notified multiple times during a single play, and are triggered when a tasks causes a change in state.
If nothing notifies a handler, it will not run. Regardless of how many tasks notify a handler, it will run only once, after all of the tasks complete in a particular play.
EXAMPLE HANDLER IN A PLAY
tasks:
- name: add cache dir
file:
path: /opt/cache
state: directory
- name: install nginx
yum:
name: nginx
state: latest
notify: restart nginx
handlers:
- name: restart nginx
service:
name: nginx
state: restarted
In this slide, we have an example of a handler in which after we install nginx, we add a notify to restart the services.
Then, there’s a handlers section in which we define that handler.
If the conditions to trigger the handler aren’t met, then the handler won’t run.
Handlers may be notified multiple times during a single play, and are triggered when a task causes a change in state.
PLAYS & PLAYBOOKS
Plays are ordered sets of tasks to execute against host selections from your inventory.
A playbook is a file containing one or more plays.
All these things we’ve been talking about including tasks, handlers, modules, etc. are all part of what make up plays and playbooks.
PLAYBOOK EXAMPLE
---
- name: install and start apache
hosts: web
vars:
http_port: 80
max_clients: 200
remote_user: root
tasks:
- name: install httpd
yum: pkg=httpd state=latest
- name: write the apache config file
template: src=/srv/httpd.j2 dest=/etc/httpd.conf
- name: start httpd
service: name=httpd state=started
ROLES
Roles are a packages of closely-related Ansible content that can be shared more easily than plays alone.
PLAYBOOK EXAMPLE
site.yml
roles/
common/
files/
templates/
tasks/
handlers/
vars/
defaults/
meta/
webservers/
files/
templates/
tasks/
handlers/
vars/
defaults/
meta/
This is how it looks from a project perspective.
Not all of these directories need to be used, these are just standards that are available and ready to fill in with your tasks, handlers, variables, whatever you need for the particular role.
PLAYBOOK WITH ROLES EXAMPLE
# site.yml
---
- hosts: web
roles:
- common
- webservers
This is how you would call a role from the main playbook.
It keeps everything simple and you can switch things out or delete easily without parsing through a huge list of tasks that you’ve made separately for every host type.

When you determine buffer size settings, you must strike a balance between communication needs and other processing.
Larger socket buffers allow your members to distribute data and events more quickly, but they also take memory away from other things. If you store very large data objects in your cache, finding the right sizing for your buffers while leaving enough memory for the cached data can become critical to system performance.
Ideally, you should have buffers large enough for the distribution of any single data object so you don’t get message fragmentation, which lowers performance. Your buffers should be at least as large as your largest stored objects and their keys plus some overhead for message headers. The overhead varies depending on who is sending and receiving, but 100 bytes should be sufficient. You can also look at the statistics for the communication between your processes to see how many bytes are being sent and received.
If you see performance problems and logging messages indicating blocked writers, increasing your buffer sizes may help.
This table lists the settings for the various member relationships and protocols, and tells where to set them.
| Protocol / Area Affected | Configuration Location | Property Name |
|---|---|---|
| TCP / IP | — | — |
| Peer-to-peer send/receive | gemfire.properties |
socket-buffer-size |
| Client send/receive | cache.xml <pool> |
socket-buffer-size |
| Server send/receive | gfsh start server or
cache.xml <CacheServer> |
socket-buffer-size |
| UDP Multicast | — | — |
| Peer-to-peer send | gemfire.properties | mcast-send-buffer-size |
| Peer-to-peer receive | gemfire.properties | mcast-recv-buffer-size |
| UDP Unicast | — | — |
| Peer-to-peer send | gemfire.properties | udp-send-buffer-size |
| Peer-to-peer receive | gemfire.properties | udp-recv-buffer-size |
TCP/IP Buffer Sizes
If possible, your TCP/IP buffer size settings should match across your Geode installation. At a minimum, follow the guidelines listed here.
- Peer-to-peer. The socket-buffer-size setting in
gemfire.properties
should be the same throughout your distributed system. Client/server. The client’s pool socket-buffer size-should match the setting for the servers the pool uses, as in these example
cache.xml
snippets:Client Socket Buffer Size cache.xml Configuration: <pool>name="PoolA" server-group="dataSetA" socket-buffer-size="42000"... Server Socket Buffer Size cache.xml Configuration: <cache-server port="40404" socket-buffer-size="42000"> <group>dataSetA</group> </cache-server>
UDP Multicast and Unicast Buffer Sizes
With UDP communication, one receiver can have many senders sending to it at once. To accommodate all of the transmissions, the receiving buffer should be larger than the sum of the sending buffers. If you have a system with at most five members running at any time, in which all members update their data regions, you would set the receiving buffer to at least five times the size of the sending buffer. If you have a system with producer and consumer members, where only two producer members ever run at once, the receiving buffer sizes should be set at over two times the sending buffer sizes, as shown in this example:
mcast-send-buffer-size=42000
mcast-recv-buffer-size=90000
udp-send-buffer-size=42000
udp-recv-buffer-size=90000
Operating System Limits
Your operating system sets limits on the buffer sizes it allows. If you request a size larger than the allowed, you may get warnings or exceptions about the setting during startup. These are two examples of the type of message you may see:
[warning 2008/06/24 16:32:20.286 PDT CacheRunner <main> tid=0x1]
requested multicast send buffer size of 9999999 but got 262144: see
system administration guide for how to adjust your OS
Exception in thread "main" java.lang.IllegalArgumentException: Could not
set "socket-buffer-size" to "99262144" because its value can not be
greater than "20000000".
If you think you are requesting more space for your buffer sizes than your system allows, check with your system administrator about adjusting the operating system limits.

class
pip_services3_components.connect.ConnectionParams.
ConnectionParams
(map=None)¶ Bases:
pip_services3_commons.config.ConfigParams.ConfigParams
Contains connection parameters to connect to external services.
They are used together with credential parameters, but usually stored separately from more protected sensitive values.
### Configuration parameters ###
- discovery_key: key to retrieve parameters from discovery service
- protocol: connection protocol like http, https, tcp, udp
- host: host name or IP address
- port: port number
- uri: resource URI or connection string with all parameters in it
In addition to standard parameters ConnectionParams may contain any number of custom parameters
- Example:
- connection = ConnectionParams.from_tuples(“protocol”, “http”,
- “host”, “<IP_ADDRESS>”, “port”, “8080”, “cluster”, “mycluster”)
host = connection.get_host() // Result: “<IP_ADDRESS>” port = connection.get_port() // Result: 8080 cluster = connection.get_as_nullable_string(“cluster”) // Result: “mycluster”
-
static
from_config
(config)¶ Retrieves a single ConnectionParams from configuration parameters from “connection” section. If “connections” section is present instead, then is returns only the first connection element.

sebgroup/bootstrap is a standalone theme built on Bootstrap 4, note that there's no dependencies to bootstrap other than the requirement to follow their markup.
sebgroup/bootstrap has no external dependency to bootstrap but since the project is built on top off bootstrap, all markup examples on their website will work for sebgroup/bootstrap too. Please note that not all components have been styled for SEB yet and this library doesn't include any Javascript either.
The later is by design as the goal and purpose of this project is to hold common styles for standard web components and not control how they work or behave as that would require additional Javascript and that is something most frameworks take care of ie. React, Angular, Vue etc. This is also the reason as to why some of the components like pagination, accordion etc. on the demo page doesn't do anything when you try to use them.
Read about how to get started in the wiki.
