Grafana – general notification for whole dashboard

Is it possible to define general notificatin for whole dashboard in Grafana? Let’s say we have many graphs on dashboard with defined thresholds. Is it possible to send general notification in case of any threshold has been crossed?

To make it clear: Dashboard with graphs for severs of the same type. Each server has several licenses for some functionalities. Each license is depicted in separate graph. I don’t want to multiply notification definitions for each license. So it would be great if it would be possible to define notification once – which would point to the dashboard OR define notification template and reuse in every graph.

Adding efficiency to general lab equipment

General equipment makes up a lab’s foundation. Without these crucial tools, few experiments could be performed, because nearly every research project depends on one or more of such technologies. As fundamental elements of research, general lab equipment must also be efficient. “Energy efficiency in laboratory equipment is extremely important,” says John Dilliott, energy manager at the University of California, San Diego. “It’s a major, yet virtually untapped area.” He mentions that My Green Lab, a California-based nonprofit, published a 2015 report estimating that there are more than 1.2 billion square feet of laboratory space in the United States. “These spaces are three to five times more energy intensive than office areas due to energy-intensive equipment, around-the-clock operations, 100 percent outside-air requirements, and high airflow rates,” Dilliott says. “Not only does laboratory equipment consume a substantial amount of energy, but anyone who has ever been in a lab knows that the heat generated by lab equipment can lead to overcompensation by heating, ventilation, and air-conditioning systems, resulting in an additional increase in energy consumption.”
By saving energy, it takes less capital to run a piece of equipment, and some of the most basic equipment consumes a lot of electricity. According to the website of the International Institute for Sustainable Laboratories (I2SL) in Arlington, Virginia: “The energy used by [plug-in] equipment (e.g., freezers, autoclaves, centrifuges) constitutes from 10 to as much as 50 percent of the total energy use in a laboratory (not including associated cooling energy use).” I2SL’s web page adds, “Many scientists, laboratory managers, and laboratory design consultants are beginning to use energy efficiency as a selection criterion for laboratory equipment, such as laboratory oven, and some manufacturers are starting to advertise the ‘green features’ of their products.” In an effort to start a central database of energy-efficiency information, I2SL created the Energy-Efficient Laboratory Equipment Wiki (
When considering any technology upgrade for energy efficiency, scientists wonder about the payback: How long will it take to recoup the price of the new equipment through energy savings? “Payback is a difficult question to answer as it’s dependent on the initial purchase price, the cost of energy, how the equipment is used, and the type of equipment that is being replaced,” says Allison Paradise, executive director of My Green Lab. “In addition, so few studies have been done on energy consumption of laboratory equipment that it’s often difficult to know, without metering, what the baseline energy consumption is of the existing equipment and what the energy consumption is of the new equipment.” She adds, “Our nonprofit cofounded the Center for Energy Efficient Laboratories (CEEL) to address this specific need”—gathering real-world data on the energy used by general lab equipment. Only with those data in hand can scientists choose the most efficient devices.

An incubator comprises a transparent chamber and the equipment that regulates its temperature, humidity, and ventilation. For years, the principle uses for the controlled environment provided by incubators included hatching poultry eggs and caring for premature or sick infants, but a new and important application has recently emerged, namely, the cultivation and manipulation of microorganisms for medical treatment and research. This article will focus on laboratory (medical) incubators.

This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example.
Laboratory shakers are a key piece of equipment in any biological laboratory. Their versatility enables scientists to easily culture, monitor and scale up a range of experiments including biofuel research and microbiological cultures. When buying a new biological shaker, it’s important to consider the experiments and applications you want to use it for and the people using it. The following guide highlights seven key matters to consider when choosing the right shaker for your laboratory.
1) Orbit size
The diameter of the orbit of your shaker is an important factor when considering different shakers; different orbit sizes suit different culturing techniques and applications.
Aeration and circulation of the growth medium in your experiment is directly affected by the orbit size, so maximise your culturing efficiency by choosing the best orbit size for your application.
Most shakers are available in a 2.5cm and 5.1cm orbit. In general, a 2.5 cm orbit is a standard option for most applications, but higher volume experiments e.g. >2 litres, or shear sensitive cells may benefit from a larger diameter orbit.
2) Shaking
Oxygenation of the cultures also depends on the speed of the agitation. By increasing the agitation speed, the surface area of the liquid increases by washing against the side of the flask, enabling better aeration of the culture if done at an optimal speed.
3) Temperature control
Biological culturing is a precise and temperamental process; sudden changes in temperature can massively affect your culture and so incorporating good temperature control is an important factor to consider in instrument selection.
Reproducibility and consistency are crucial when culturing, so it’s also important to consider the uniformity of any heating/cooling across the whole of your shaker.

A laboratory muffle furnace is a critical component for high-temperature laboratory heating, enabling samples to be heat-treated at temperatures exceeding 1000°C (1832°F) with low risk of cross-contamination.

Rotary evaporator packages have been around for quite some time now, having been developed over 50 years ago to deal with problems faced with standard chemical distillation devices. Those issues included annihilation of the substances being distilled and slow boiling. Rotary evaporators prevent such problems through the spinning motion of the vessel, which speeds distillation by increasing the surface area of the liquid. This type of evaporator also provides a gentler, higher quality distillation process than standard procedures, according to a white paper from IKA. All basic rotary evaporators are made up of a vacuum source, collection flask, rotating flask, temperature bath and condenser. While oil may be used for the bath in order to reach temperatures of 180 C, water is the most commonly used substance. If you’re looking for a rotary evaporator, it’s important to think about whether or not you need automated options and what cooling option is best for you. Vacuum control is also crucial as vacuum that is achieved too quickly can cause foaming and bumping. As always, consulting your vendor can help you make the right choice of rotary evaporator for your lab.

The growth of Life science products has created geographic concentrations of interconnected life sciences companies and institutions, or “clusters,” forming in key global locations, including in the U.S. and the UK. The forming of clusters has been driven by a variety of factors, including a broad recognition that proximity between market participants can drive overall productivity. While it may seem paradoxical for a company to locate near its competitor, a deeper examination reveals that clustering creates synergies for all participants who can benefit from communal resources, regional trade, lobby and support groups, shared infrastructure and logistics channels, and a common regulatory and legal framework (and, in some instances, local tax incentives). 

Traditionally, life sciences clusters have organically developed over time near recognized research universities and teaching hospitals, as these provide ready access to talent across key scientific disciplines and easy means for intellectual property transfer from these institutions to private companies. In recent times, traditional big spenders on R&D in the life sciences sector (like big pharma) have increasingly favoured collaboration, often with smaller venture-funded companies that have spun out from leading academic institutions, as a means of achieving a stake in innovation while reducing in-house R&D risk and expenditure. An interesting by-product of the growth of venture-funded companies is the increasing availability of flexible short-lease lab spaces targeted at covenant weak start-ups and SMEs.

Why is the general community of this site so toxic?

Having read replies to simple questions on this site my immediate reaction was “What a bunch of stuck up cunts.”. People genuinely asking for clarification on rulings who may have missed a line, or not understood something in the PHB are routinely being ridiculed for putting in the effort to learn. Are the majority of users on this site just insecure egotists trying to validate themselves by mocking others and flexing their “abundance of free time”?

Trying to ask the moderator a question but don’t have 20 rep to ping in general Chat. How do I PM the moderator?

Last post was deemed an advertisement by moderator. Not trying to place ads but see if anyone wants to play a new game we have. How can you do that without mentioning the name of the game? It is already published, just new and not as well known as DnD and other stuff you can mention. And just because it is OUR game, the mod sees it as self promotion. Should I log in as someone else and lie and say "Wow guys, I just learned of an awesome new game that isn’t my own… let’s play."

Not trying to be cheeky here, and didn’t want to say all this in public here, but really, 20 rep just to talk on general chat to ping moderator? Come on.

How to create a clickable static call us button that links to a new setting in general

I recently had an admin setting created on my website that allows me to input a contact number to display on the front end via a shortcode.

Now I am now trying to use this field to also create a clickable and static call button for mobile devices only that appears on the bottom of their screens.

There are plugins like WP Call Button that achieve this, but I am trying to keep my website as light as possible. Any help would be much appreciated!

I think I may need another 2 admin fields created that act as a text label as well as the hyperlink function? e.g. tel:035555555?

enter image description here

Here’s the code that was created (thanks again Walter) for my general settings:

/**  * Class for adding a new field to the options-general.php page  */ class Add_Settings_Field {      /**      * Class constructor      */     public function __construct() {         add_action( 'admin_init' , array( $  this , 'register_fields' ) );     }      /**      * Add new fields to wp-admin/options-general.php page      */     public function register_fields() {         register_setting( 'general', 'phone_number_custom', 'esc_attr' );         add_settings_field(             'custom_phone_number',             '<label for="custom_phone_number">' . __( 'Phone Number' , 'phone_number_custom' ) . '</label>',             array( $  this, 'fields_html' ),             'general'         );     }      /**      * HTML for extra settings      */     public function fields_html() {         $  value = get_option( 'phone_number_custom', '' );         echo '<input type="text" id="custom_phone_number" name="phone_number_custom" value="' . esc_attr( $  value ) . '" />';     }  } new Add_Settings_Field();

Is it safe to use the Windows “Compress directory to save space” feature on the directory that contains my MySQL general log file?

I have changed MySQL 8 on my Windows 10 development machine to write logfiles (general log and slow queries log) to "E:\mysql logfiles". I’d like to compress this directory using the Windows "Compress Directory to save space" advanced feature in the Windows 10 directory properties to save space (currently my logfile is over 50 GB). I’m wondering though: is this a good idea? Or will this break MySQL in (subtle or not) ways?

Silence = -4 to Notice against Sounds, but what about Notice against Stealth in general?

Silence gives anyone who tries to hear you -4 to their Notice roll (or an auto-fail with a Raise), but how much does this spell influence your Stealth roll where you also have to stay out of sight?

I am planning on combining Silence (-4/auto-fail to Notice) and Invisibility (-4/-6 to Notice), but I don’t know how to combine these numbers. Without the auto-fail I would’ve just added them up, but the auto-fail gives me the impression that it was intended that I don’t do that in general with these spells.

How to obtain eigenvalues from an ODE’s general solution?

For this second-order linear ODE (eigenvalue e) $ $ y”(x) – 2g\, y'(x) + [-e + g^2 – (\frac{b^2x^2}{2}+a)^2 + b^2x]\, y(x)=0$ $ I know the correct analytical general solution form with two undetermined constants c1,c2 (verified in the code below where y1,y2 is given) $ $ y=c1\,y1(x)+c2\,y2(x)$ $ I want to impose the boundary condition $ y(\pm5)=0$ in order to get the eigenvalue $ \lambda$ . (Actually $ y(\pm\infty)=0$ , but not much numerical difference, I suppose.) So I put c1=1 and tried FindRoot e and c2 together, but it didn’t work well. So I was wondering if I need to tune any option or some other methods?
I also add a direct numerical solution as a reference.

F := (D[#, {x, 2}] -       2 g D[#, x] + (-e + g^2 - (b^2 x^2/2 + a)^2 + b^2 x) #) &; y1[x_] := E^(-(1/6) b^2 x^3 - x a + x g) HeunT[e, 0, -2 a, 0, -b^2, x]; y2[x_] := E^(-(1/6) b^2 x^3 - x a + x g) HeunT[e, 0, -2 a, 0, -b^2, x]; y[x_] := c1 y1[x] + c2 y2[x]; F[y[x]] == 0 // FullSimplify  g = 0.2; a = 0.3 - I 0.3; b = 1; FindRoot[0 ==     y[x] /. {{c1 -> 1, x -> 5}, {c1 -> 1, x -> -5}}, {{e, -0.3}, {c2,     1}}, WorkingPrecision -> 55]  FF = F /. e -> 0; {vals, funs} = NDEigensystem[FF[yy[x]], yy[x], {x, -5, 5}, 5]; vals Plot[Evaluate@Abs@funs, {x, -5, 5}, PlotRange -> All,   PlotLegends -> Automatic]
